Valproate (depakine-chrono) in the acute treatment of outpatients with generalized anxiety disorder without psychiatric comorbidity: Randomized, double-blind placebo-controlled study
Authors: Aliyev Nadir A. , Aliyev Zafar N.
Published: December 2007

Objective

Anxiety disorders are highly prevalent in population of European countries. However, the effect of Valproate (depakine-chrono) on generalized anxiety disorder (GAD) has not been studied in a double-blind placebo-controlled design.

Method

Eighty patients (all men) were washout from the all medications. Each patient was randomized to receive either depakine-chrono (40 patients) for 6 weeks or matched placebo (40 patients) in a double-blind manner. Eligible participants, in addition to meeting the DSM-IV criteria for GAD and having a minimum score of 25 and more on the Hamilton Anxiety Scale, were required to be between 18 and 65 years. Response was defined as a 50% reduction in the Hamilton anxiety scale score. Response and side effects with depakine-chrono and placebo were compared by using analysis of variance (ANOVA) and chi-square tests. Six patients did not return for at least one subsequent assessment, leaving 74 patients (36 taking depakine-chrono and 38 taking placebo) in the valuables study group.

Results

Twenty six of the 36 depakine-chrono-treated participants responded by 6 weeks, versus six of the 38 placebo-treated participants (p< 0.001). The most common and problematic side effect in the depakine-chrono group was dizziness and nausea.

Conclusions

The authors believe this to be the first double-blind placebo-controlled randomization study to test the efficacy of a depakine-chrono in the management of anxiety disorders. They need to be replicated in a larger study group.
Intimate partner violence and unplanned pregnancy in the Pacific Islands Families Study
Authors: Gao Wanzhen , Paterson Janis , Carter Sarnia , Iusitini Leon
Published: December 2007

Objective

To examine the association between maternal intimate partner violence (IPV) victimization and unplanned pregnancy.

Method

Mothers of the Pacific Islands Families (PIF) Study cohort of Pacific infants born in Auckland, New Zealand during 2000 were interviewed when the children were 6 weeks old. A total of 1088 mothers cohabiting in married or de‐facto partnerships were questioned about IPV and whether their pregnancy had been planned.

Results

Women identified as victims of physical violence were more likely to report an unplanned pregnancy than those who were not victims (68.7% vs 55.1%, odds ratio [OR] 1.78; 95% confidence interval [CI], 1.32–2.40). The adjusted odds remained statistically significant (OR 1.52; 95% CI, 1.01–2.26).

Conclusion

The findings of this study suggest an association between IPV and unplanned pregnancy in the Pacific birth cohort.
Feline dysautonomia in the Midwestern United States: A retrospective study of nine cases
Authors: Kidder Aimee C. , Johannes Chad , O'Brien Dennis P. , Harkin Kenneth R. , Schermerhorn Thomas
Published: December 2007

Dysautonomia of domestic animals is pathologically characterized by chromatolytic degeneration of the neurons in the autonomic nervous ganglia that results in clinical signs related to dysfunction or failure of the sympathetic and parasympathetic nervous systems. The exact cause is unknown. It has a poor prognosis among all species reported and no definitive treatment is available currently. To date, most reported feline cases have occurred in the United Kingdom and Scandinavia. The cases reported here highlight the clinical signs, physical examination findings, and results of autonomic nervous system function testing in nine cats with dysautonomia in the US. Feline dysautonomia is uncommon in the US, but may have a regional prevalence, as is seen in dogs with most cases reported in Missouri and Kansas.
Taxonomy of some sponges (Porifera: Demospongiae) collected from the Aegean Sea and description of a new species
Authors: Kefalas E. , Castritsi-Catharios J.
Published: December 2007

A systematic survey of the sponge fauna of the Aegean Sea has been carried out. Twenty-eight stations located in the Aegean Sea were explored and 59 species of Demospongiae were collected from this particular area, which covers a broader geographical area of the Aegean and Cretan Seas. Some of the species found are poorly known for the Mediterranean fauna, like Cerbaris curvispiculifera and Spongosorites flavens, which are reported for the first time in the Aegean Sea and generally in the eastern Mediterranean. The species Axinyssa michaelis sp. nov. (Halichondriidae: Halichondrida) is new to science. In this paper, a description of the new species is presented along with the description of the first recorded species in the Aegean Sea. In addition to the taxonomic description of the species, some ecological data and a distribution pattern are also presented.
Harmful effects of the toxic dinoflagellate Alexandrium tamarense on the tintinnids Favella taraikaensis and Eutintinnus sp.
Authors: Fulco V. Karin
Published: December 2007

The effects of the exposure of two tintinnids (Favella taraikaensis and Eutintinnus sp.) to the toxic dinoflagellate Alexandrium tamarense were studied, using the non-toxic dinoflagellate Scrippsiella trochoidea as a control. The tintinnid F. taraikaensis showed backward swimming and cellular lysis after a few minutes in the presence of the toxic dinoflagellate A. tamarense in high concentration (280–700 cells ml-1). At low concentrations of A. tamarense (30–120 cells ml-1) no swimming alterations were observed, but cellular lysis occurred after 48 hours. No changes in the swimming patterns were observed when Eutintinnus sp. was exposed to either toxic dinoflagellates or cell-free filtrate, or when F. taraikaensis was exposed to cell-free filtrate. However, both tintinnids suffered cellular lysis after 48 hours of exposure. Favella taraikaensis and Eutintinnus sp. remained healthy after preying on the non-toxic S. trochoidea for 48 hours. In selectivity experiments, F. taraikaensis avoided cells of the toxic dinoflagellates during the dark phase. Our results suggest that tintinnids could play a regulatory role when the toxic blooms are initiating and the toxic cell concentrations remain still low in the northern Patagonian gulfs of Argentina. Since tintinnids are affected by substances released by A. tamarense, predation on dinoflagellates would not occur during the peak of the bloom.
UV radiation influences covering behaviour in the urchin Lytechinus variegatus
Authors: Sigg Jessica E. , Lloyd-Knight Karena M. , Boal Jean Geary
Published: December 2007

Many species of sea urchins cover their bodies with a variety of materials. One hypothesis for this behaviour is that the urchins are reducing their exposure to UV radiation. The effect of UV radiation on the covering behaviour of twelve sea urchins, Lytechinus variegatus, was recorded and the shells used as covering materials were quantified. During UV exposure, urchins used significantly greater numbers, areas and masses of shells than did urchins during non-UV exposure. Results suggest that not only were L. variegatus covering in response to UV exposure, but they were also making distinct choices regarding preferred covering items. Unlike in previous studies, the urchins did not simply choose familiar objects or even the lightest objects; rather, when exposed to UV radiation they selected intermediate-sized objects, perhaps demonstrating a trade-off between the energetic costs of carrying objects and the physiological costs of exposure to UV radiation. While there appear to be many reasons for why urchins cover, these results indicate that urchin covering is non-random and has important functional significance.
Effects of algal diet on larval survival and growth of the barnacle Amphibalanus (=Balanus) improvisus
Authors: Nasrolahi Ali , Sari Alireza , Saifabadi Seyedjafar , Malek Masoumeh
Published: December 2007

The effects of algal diet on larval survival and growth of the barnacle Amphibalanus
improvisus was for the first time examined under controlled laboratory conditions. Larvae
were obtained by dissecting egg lamellae at later developmental stage out of the adults. Hatched
nauplii were reared in 0.6-l glass beakers (200 larvae l-1) on a monoalgal diet of
Chaetoceros calcitrans, Chlorella vulgaris and Scenedesmus quadricauda at
1x105 and 2x105 cells ml-1, under continuous light at
25 ±1°C. The rate of development, survival and size (at Stage V) of the larvae were
measured for each diet. The majority of nauplius II larvae (~70%) fed with Cha. calcitrans
and Chl. vulgaris developed into cyprids within seven days while those fed with
S. quadricauda remained at Stage II. A shorter time interval for Stage II to III
was observed in larvae fed with a Chl. vulgaris monoalgal diet than Cha.
calcitrans. Larvae fed with Cha. calcitrans had shorter developmental
intervals for later larval stages (Stages IV–VI). The highest mortality was observed
in the treatment with a monoalgal diet of S. quadricauda, while the highest survival
was achieved with a diet of Cha. calcitrans. The mixed diet of Cha. calcitrans,
Chl. vulgaris and S. quadricauda resulted in a shorter developmental duration
of larval cycle (six days). Both food type and food concentration significantly affected the
length and width of the nauplius larvae.
Occurrence of Paraleucilla magna (Porifera: Calcarea) in the Mediterranean Sea
Authors: Longo Caterina , Mastrototaro Francesco , Corriero Giuseppe
Published: December 2007

The calcareous sponge Paraleucilla magna has been detected at different Mediterranean sites (Taranto, Porto Cesareo, Brindisi and Naples). Its record in well studied areas where several benthic surveys have previously been carried out suggests a recent introduction of the species into the Mediterranean Sea. Until now this sponge has only been recorded from the Brazilian coast. It shows different morphologies, varying from tubular to an irregular massive shape with several folds occurring on its surface. The colour is white-cream. The surface is smooth. The consistency is friable. The oscula are 10–20 mm in diameter and located at the top of tubular protrusions. The skeleton consists of cortical and subatrial triactines and tetractines, together with atrial triactines, differently distributed in the sponge body. Paraleucilla magna is abundant in eutrophic environments, where seasonally it may reach very high frequency values and large dimensions. It is resistant to pollution, but it is also able to live in clean waters. The inclusion of this species among Mediterranean alien invasive species is suggested.
Assessing anti-predatory chemical defences among ten eastern Mediterranean sponges
Authors: Sokolover N. , Ilan M.
Published: December 2007

The palatability of organic chemical extracts from ten of the most abundant sponge species along the Israeli (shallow) coast, eastern Mediterranean Sea (Axinella sp., Axinella polypoides, Chondrilla nucula, Ircinia sp., Psammocinia sp. 1, Psammocinia sp. 2, Psammocinia sp. 3, Psammocinia sp. 4, Sarcotragus sp. and Tetilla sp.) was tested. To examine the generality of the phenomenon, it was evaluated with two types of potential predators, a fish and a gastropod. It was determined that the extracts of only two species (Psammocinia sp. 1 and Psammocinia sp. 3) deterred feeding of the omnivorous ornate Mediterranean wrasse Thalassoma pavo. On the other hand, extracts of five other sponges (Chondrilla nucula, Axinella sp., Ircinia sp., Sarcotragus sp. and Psammocinia sp. 2) were non-palatable to the omnivorous gastropod Strombus persicus (the extracts that deterred the fish did not deter the gastropod and vice versa). We also determined the capacity of extracts from six Red Sea sponges to deter T. pavo, and compared it with these extracts' effect on the Red Sea wrasse T. klunzingeri. All the extracts that deterred the Red Sea wrasse (from Amphimedon chloros, Crella cyatophora, Negombata magnifica and Theonella swinhoei) were also non-palatable to the Mediterranean wrasse. In addition to these four species, also Diacarnus erythraenus deterred Thalassoma pavo while being palatable to T. klunzingeri, whereas food pellets with extracts of Niphates rowi were eaten by both wrasse species.
Intergenerational transmission of symbiotic bacteria in oviparous and viviparous demosponges, with emphasis on intracytoplasmically-compartmented bacterial types
Authors: Maldonado Manuel
Published: December 2007

Recent molecular detection of vast microbial communities exclusively associated with sponges has made evident the need for a better understanding of the mechanisms by which these symbiotic microbes are handled and transferred from one sponge generation to another. This transmission electron microscopy (TEM) study investigated the occurrence of symbiotic bacteria in free-swimming larvae of two viviparous species (Haliclona caerulea and Corticium candelabrum) and spawned gametes of two oviparous species (Chondrilla nucula and Petrosia ficiformis). Complex microbial communities were found in these sponges, which in two cases included bacteria characterized by an intra-cytoplasmic membrane (ICM). When ICM-bearing and ICM-lacking bacteria co-existed, they were transferred following identical pathways. Nevertheless, the mechanism for microbial transference varied substantially between species. In C. nucula, a combination of intercellular symbiotic ICM-bearing and ICM-lacking bacteria, along with cyanobacteria and yeasts, were collected from the mesohyl by amoeboid nurse cells, then transported and transferred to the oocytes. In the case of Corticium candelabrum, intercellular bacteria did not enter the gametes, but spread into the division furrows of early embryos and proliferated in the central cavity of the free-swimming larva. Surprisingly, symbiotic bacteria were not vertically transmitted by P. ficiformis gametes or embryos, but apparently acquired from the environment by the juveniles of each new generation. This study failed to unravel the mechanism by which the intercellular endosymbiotic bacterium found in the central mesohyl of the H. caerulea larva got there. Nevertheless, the ultrastructure of this bacterial rod, which was characterized by a star-shaped cross section with nine radial protrusions, an ICM-bound riboplasm, and a putative membrane-bound acidocalcisome, suggested that it may represent a novel organization grade within the prokaryotes. It combines traits occurring in members of Poribacteria, Planctomycetes and Verrucomicrobia, emerging as one of the most complex prokaryotic architectures known to date.
Three new species of Crambe (Crambeidae: Poecilosclerida: Demospongiae) from the south-eastern Pacific, with a review of morphological characters for the genus
Authors: Esteves Eduardo L. , Lôbo-Hajdu Gisele , Hajdu Eduardo
Published: December 2007

Three new species of Crambe are described from the upper and middle-southern coast of Chile, south-east Pacific. Crambe chilensis sp. nov. and C. amarilla sp. nov. are astroclone bearing species, while C. maldonadoi sp. nov. has sphaeroclones as asterose desmas. Morphological characters of Crambe were re-evaluated to consider this unsuspected high diversity of Crambe in the south-east Pacific. The main characters for the distinction of Chilean species as well as of other Crambe species were the live-colour; the shape and size of asterose desmas and (sub)(tylo)styles; the shape, number of categories and size-range of anchorate isochelae; and the presence/absence and dimensions of spined microxeas. An identification key for the Crambe of the world is provided. If astroclone and sphaeroclone desma-bearing species groups would represent two distinct evolutionary lineages, then the south-eastern/eastern Pacific Region would have been occupied by two evolutionary lineages with distinct life histories. The relatively high diversity of Crambe in the Chilean temperate coast, together with its occurrence in New Zealand's Oligocene, is suggestive of a likely wide distribution in Panthalassa, which contrasts to earlier suggestions of wide distribution in the Tethyan Realm only.
Sponge biodiversity of Rathlin Island, Northern Ireland
Authors: Picton B.E. , Goodwin C.E.
Published: December 2007

Sponges from Rathlin Island, Northern Ireland were sampled during a six week SCUBA diving expedition. One hundred and twenty-eight species were recorded, 29 of which were previously undescribed. With previous records a total of 134 species are now known from Rathlin, the richness of its sponge community makes it a key site for sponges in Europe. Eight new species are described: Axinella parva, Spongosorites calcicola, Crella plana, Phorbas punctata, Lissodendoryx (Ectyodoryx) jenjonesae, Antho (Antho) granditoxa, Hymeraphia breeni and Hymeraphia elongata and information is given on the poorly known species Axinella pyramidata, Myxilla (Styloptilon) ancoratum, Antho (Antho) brattegardi, Clathria (Microciona) laevis and Plocamionida tylotata. Extension of the range of Hexadella racovitzai is discussed. A small bay of particularly high nature conservation importance for sponges was identified, many of the rarer species were limited to this area. Sponge populations on the east coast of Rathlin seem to have been damaged by dredging.
New genus and species of Polymastiidae (Demospongiae: Hadromerida) from the Antarctic deep sea
Authors: Plotkin Alexander S. , Janussen Dorte
Published: December 2007

A new sponge genus and species, Astrotylus astrotylus, is described from the Antarctic abyssal zone. Its peculiar microscleres, herein referred to as astrotylostyles, combine the features of asterose spicules and tylostyles. Similar spicules are observed in Hymeraphia and Discorhabdella (order Poecilosclerida). But this similarity is convergent as far as a radial choanosomal skeleton composed by principal tylostyles and a cortical palisade of small tylostyles in Astrotylus undoubtedly confirm its allocation to the order Hadromerida and most likely to the family Polymastiidae. Atergia, Acanthopolymastia and Tylexocladus have the closest affinities with Astrotylus that calls for the phylogenetic analysis of their relations. Meanwhile astrotylostyles of Astrotylus, cladotylostyles of Tylexocladus and grapnel-like exotyles of Proteleia may be the remnants of non-monaxonic ancestral spicule type in Polymastiidae that calls for reconsideration of the relations between hadromerid families.
Revision of the genus Asconema (Porifera: Hexactinellida: Rossellidae)
Authors: Tabachnick Konstantin R. , Menshenina Larisa L.
Published: December 2007

The genus Asconema, widely distributed in the North Atlantic and Arctic, was for some time considered to be monospecific. Its revision shows that it contains five species including the previously known A. setubalense, reinstated A. foliata and three new species (two of which are subdivided into three and four subspecies). The generic diagnosis is changed to encompass the specific characters of the new species.
Towards a DNA taxonomy of Caribbean demosponges: a gene tree reconstructed from partial mitochondrial CO1 gene sequences supports previous rDNA phylogenies and provides a new perspective on the systematics of Demospongiae
Authors: Erpenbeck Dirk , Duran Sandra , Rützler Klaus , Paul Valerie , Hooper John N.A. , Wörheide Gert
Published: December 2007

We present the most comprehensive cytochrome oxidase subunit 1 gene tree published to date for demosponges based on new sequences. The CO1 barcoding fragment is sequenced for 65 species from the Caribbean Sea, and its gene tree reconstructed. Although its deeper nodes are not particularly well-supported, the gene tree provides a variety of information for new phylogenetic patterns, as well as support for previously published 28S rDNA gene trees. In our analysis Halichondriidae cluster with Suberitidae, supporting previous 28S rDNA data. Chelae-bearing Poecilosclerida are monophyletic but most taxa lacking chelae in this dataset cluster more distantly. Haplosclerida are not resolved monophyletically under this fragment. While some species exhibit distinct barcodes, some genera contain species that share CO1 haplotypes.
The systematics of Raspailiidae (Demospongiae: Poecilosclerida: Microcionina) re-analysed with a ribosomal marker
Authors: Erpenbeck Dirk , List-Armitage Sue , Alvarez Belinda , Degnan Bernard M. , Wörheide Gert , Hooper John N.A.
Published: December 2007

We present a 28S rDNA gene tree of selected Raspailiidae, Axinellidae and other demosponges to obtain insight into raspailiid phylogeny and character evolution. The Raspailiidae in our data set cluster in a well-supported clade, distinguished from Axinellidae, Agelasida and Hadromerida. Raspailia (s.s.), Eurypon, Sollasella, Aulospongus and Ectyoplasia form a Raspailiidae clade. Some Raspailia subgenera, in particular R. (Parasyringella), are not retrieved monophyletically. Trikentrion falls into the Thrinacophorinae, and not the Cyamoninae as earlier hypothesized. The axinellid genera Ptilocaulis and Reniochalina also cluster with Raspailiidae, distant from the other Axinellidae. The suitability of particular morphological characters for raspailiid phylogeny is discussed.
Phylogeny of the genus Tethya (Tethyidae: Hadromerida: Porifera): molecular and morphological aspects
Authors: Heim Isabel , Nickel Michael , Brümmer Franz
Published: December 2007

The genus Tethya represents a large cosmopolitan group of 81 recognized and a significant number of additional, still undescribed sponge species. The phylogenetic relationships within this old taxon are almost unknown. This is represented by the fact that several species are regarded as cosmopolitan. However, some of them might represent groups of closely related but distinct species. Using molecular and morphological characters, we aimed at a fundamental phylogenetic study for the genus Tethya, evaluating an existing morphological matrix and the cytochrome oxidase subunit I (COI) as a molecular marker. Intending to create a basic phylogenetic framework for the genus we selected a number of species from main biogeographic regions covered by Tethya species: from the Mediterranean Sea (T. citrina and T. aurantium), the northern European seas (T. citrina, T. norvegica and T. hibernica), the western Atlantic (T. actinia), the eastern Pacific (T. californiana), the Indo-Pacific (T. seychellensis) as well as three species of unknown biogeographical origin, originally described from aquarium habitats (T. wilhelma, T. gracilis and T. minuta). Both the morphological matrix, consisting of 29 characters and 131 character states, as well as the molecular matrices (COI nucleotide sequences of 658 bp as well as deduced amino acid sequence of 219 aa), resolved major biogeographical subgroups within the genus. However, the nucleotide based matrices revealed a higher resolution. Two major branches seem to have diverged early: an Indo-Pacific (T. seychellensis, T. wilhelma, T. minuta) and a Pan-European clade (T. citrina, T. norvegica, T. hibernica). For T. aurantium as well as a North-American group (T. californiana, T. actinia and T. minuta) our results are not conclusive. The morphological character set will have to be re-evaluated to gain a higher phylogenetic resolution. The addition of more species to our basal phylogenetic framework will allow analysing the evolution of the various biogeographical subgroups in the genus Tethya.
Demosponge fauna of Ormonde and Gettysburg Seamounts (Gorringe Bank, north-east Atlantic): diversity and zoogeographical affinities
Authors: Xavier Joana , van Soest Rob
Published: December 2007

Seamounts, although abundant features of the world's oceans, constitute one of the least studied marine ecosystems. In the present work we assessed the diversity and zoogeographical affinities of the demosponge assemblages of Gettysburg and Ormonde Seamounts (Gorringe Bank, north-east Atlantic). Twenty-three demosponge species were identified adding to the thirteen previously reported for Gorringe shallow-water. Gorringe's demosponge assemblage was found to be mainly composed of species with a wide Atlanto–Mediterranean distribution (61%) and a group of species (28%) that are endemic to this Bank or have a restricted geographical distribution. This high level of endemism suggests the Gorringe Bank as a hotspot for demosponge fauna in the north-east Atlantic. Gorringe demosponge fauna was found to present an overall moderate similarity to the Mediterranean, Iberian coasts and Macaronesian archipelagos. We compare our findings with patterns reported for fish and molluscan faunas for this Bank and discuss some evolutionary aspects on the role of these ecosystems for the north-east Atlantic marine biota.
Human usage of mermaid's glove sponge (Isodictya palmata) on the Faroes
Authors: Svanberg Ingvar
Published: December 2007

There is very little documentation on the economic importance of locally available marine sponges (Porifera) in north-western Europe. From Iceland and the Faroe Islands there are records of naming and using the so-called mermaid's glove sponge (Isodictya palmata) especially for cleaning purposes. As late as in the 1940s, school children in the Faroe Islands gathered this sponge and used it to clean the slate.
Fragmentation and clearance of Liberia's forests during 1986-2000
Authors: Christie T. , Steininger M.K. , Juhn D. , Peal A.
Published: December 2007

We report estimates of the area and rate of loss and fragmentation of Liberian forests from 1986 to 2000. These estimates are based on comprehensive mapping using Landsat satellite imagery, which has a resolution of 28.5 m. We estimate a total forest cover of 4.65 million ha in 1986 and 4.33 million ha in 2000. Most of Liberia's remaining forest is in two large regions. These forests are very important biologically because they are the largest remaining forest areas in West Africa. The average deforestation rate was low at 0.2% per year during 1986–2000. Although the fragmentation of Liberia's forests is also relatively low, most of the remaining forest is readily accessible as it is within a few km of existing roads. This ease of accessibility suggests that the present low deforestation rate could increase if conservation planning is not effectively implemented.
Assessing the conservation status of the tiger Panthera tigris at priority sites in Peninsular Malaysia
Authors: Lynam Antony J. , Laidlaw Ruth , Wan Noordin Wan Shaharuddin , Elagupillay Sivananthan , Bennett Elizabeth L.
Published: December 2007

Wildlife managers require status and distribution information for informed decisions. Recognizing the tiger's globally threatened status and potential as an umbrella species for protection of forested landscapes, camera trap surveys for tigers and other large mammals have been conducted since 1997 in Peninsular Malaysia with the aim of assessing the population status of tigers in the Peninsula. Results from surveys at nine sites between December 1997 and December 1999 are reported here. Tigers were confirmed from six sites in the Main Range and Greater Taman Negara landscape, with multiple locations inside putative priority tiger areas. Although the data were collected 8 years ago, they are supplemented with more recent information, including tiger-human conflict investigations during 2000–2005 that indicate tiger persistence at these sites. Tiger density estimates were 0.51–1.95 tigers per 100 km2. With results from other surveys, this suggests a national population of up to several hundred tigers. A thorough survey, with sufficient resources, should be carried out in the future to derive a more reliable tiger population estimate for Malaysia. Key threats are habitat loss and fragmentation, hunting of prey, commercial trade in tiger parts, and harassment and displacement. Recommendations for the recovery of tigers in Peninsular Malaysia are provided.
Partnerships for tropical conservation
Authors: Vermeulen Sonja , Sheil Douglas
Published: December 2007

Achieving effective conservation in the tropics is a global concern but implicates local people. Despite considerable rhetoric about local participation the vast majority of conservation initiatives continue to be devised and controlled by a small group of powerful, external voices. What is widely overlooked is that local people often have positive conservation goals and preferences. These overlap with global values and create a strong precedent for practice, providing the basis for strategic alliances with conservation agencies. Local people can be part of a solution, rather than of the problem, if they are given the opportunity. While as yet unfamiliar to many conservationists, partnerships with local people are working in other natural resource sectors (water, commercial forestry). Strong partnerships entail shared decision making, shared risks and a balance of rights and responsibilities between external conservation agencies and local interest groups. Partnerships are no panacea, but a real commitment to partnership offers conservation outcomes that are more ethical and often more practicable than current models.
The use of hydroelectric lakes by giant ottersPteronura brasiliensis: Balbina lake in central Amazonia, Brazil
Authors: Rosas Fernando C.W. , Ely de Mattos Gália , Mendes Cabral Márcia Munick
Published: December 2007

Data on the occurrence and habitat use of giant ottersPteronura brasiliensisin the 4,437 km2of Balbina hydroelectric lake in central Amazonia, Brazil, were collected from September 2001 to December 2005. Twenty-nine groups of giant otters were recorded in an area corresponding to 10% of the total reservoir. Despite the fact that it is a hydroelectric lake, the water level can vary annually by up to 3.5 m with the Amazonian seasonal flood pulse. A total of 210 dens, communal latrines and campsites of giant otters were located. An average of 37% of the dens observed were classified as in use, and the species was recorded in the lake throughout the year. Giant otters started their daily activities between 05.23 and 08.05. The average height of den openings was 28.77 ± SD 10.00 cm, with an average width of 56.11 ± SD 19.17 cm. Births in Balbina occur mainly during the period of high and receding water level, as reported for giant otters in other Amazonian areas. There are at least two conditions that enable the species to inhabit hydroelectric reservoirs: (1) presence of the species in the area before dam construction and (2) absence or low numbers of human communities around the reservoir. The potential use of hydroelectric lakes for the conservation of the giant otter in the Amazon is discussed.
Extirpation and reintroduction of the Corsican red deer Cervus elaphus corsicanus in Corsica
Authors: Kidjo Nicolas , Feracci Gérard , Bideau Eric , Gonzalez Georges , Mattéi César , Marchand Bernard , Aulagnier Stéphane
Published: December 2007

The Endangered Corsican red deer Cervus elaphus corsicanus was extirpated from Corsica in the early 1970s, at which time the Sardinian population fell to <250 individuals. The Sardinian authorities agreed to protect this subspecies and to secure its reintroduction in Corsica, a natural choice, considering ethological and historical descriptions. Since the beginning of 1985, when the first deer destined for captive breeding and eventual reintroduction arrived in Corsica, the population increased from 13 Sardinian founders to 106 captive animals under constant monitoring in three enclosures (Quenza, Casabianda and Ania di Fium'Orbu). The sites of Quenza, Chisà and Santo Pietro di Venaco were selected by the Regional Nature Park of Corsica for the reintroduction into the wild that began in 1998. Currently the size of the whole Corsican population is c. 250 individuals. These deer are still closely monitored and studied, both in enclosures and in the wild, to secure the long-term conservation of this subspecies. The Corsican and Sardinian populations together now total slightly >1,000, and the subspecies could therefore be downgraded to Near Threatened on the IUCN Red List.
Habitat preferences of tigers Panthera tigris in the Sundarbans East Wildlife Sanctuary, Bangladesh, and management recommendations
Authors: Khan M. Monirul H. , Chivers David J.
Published: December 2007

We examined the habitat preferences of tigers Panthera tigris in four habitat types in the Sundarbans East Wildlife Sanctuary, Bangladesh. Transect sampling was used to count tiger signs. Mean densities of signs of feeding, resting, defaecation and interaction were significantly different between the four main habitat types (mangrove woodlands, grasslands, sea beaches and transitional areas), whereas movement, scratch-scent-urinal and other signs were not significantly different. This indicates that tigers have habitat preferences for at least some activities. Similar patterns were found in the densities of movement and feeding signs, as well as of resting and defaecation signs, across the four different habitat types. Tigers were found to use soft-barked trees for scratching more often than other types.
Distribution, status and conservation of the black-and-white snub-nosed monkey Rhinopithecus bieti in Tibet

Published: December 2007

The black-and-white snub-nosed monkey Rhinopithecus bieti (Colobinae), categorized as Endangered on the IUCN Red List, is endemic to the Trans-Himalayas (the Hengduan Mountains) of north-west Yunnan and south-east Tibet. To evaluate the species’ current status in Tibet we surveyed six sites in Honglaxueshan National Nature Reserve, believed to be the area's only remaining location of R. bieti. Sites were identified from previous surveys and interviews with villagers and local officials. Three sub-populations, with a total of >300 individuals, were located in conifer and evergreen broad-leaf forests, which together comprise 971 km2. One of the sub-populations, in Zhina, is a new discovery, and is the northernmost known sub-population of R. bieti. Identified threats to the species include habitat destruction through wood extraction, uncontrolled grass fires, cutting of oak Quercus aquifolioides branches, inappropriate attitudes to R. bieti when people carry out economic activities in the forest, and hunting. Opportunities for conservation include the existence of sacred mountains, the limited possibilities for agriculture, and the economic dependency of villagers on the forest. We recommend the development of a sustainable ecosystem to reduce pressure on R. bieti and its forest habitat, including use of solar energy for heating and cheap electricity for cooking to minimize dependence on firewood, introduction of techniques for high crop yields to improve food supplies, and release of some farmland for planting grass, which can be used to raise livestock in enclosures and thus reduce the cutting of oak.
Conservation of turtles in Vietnam: a survey of Cat Tien National Park
Authors: Le Minh
Published: December 2007

Turtles in South-east Asia, especially in Vietnam, have been overexploited for more than a decade, largely because of international trade with and demand from China. This study examined natural populations in Cat Tien National Park and the local trade in surrounding areas to find ways of protecting remaining turtle populations more effectively. The results show that although trade around this protected area remains high, viable turtle populations still exist. However, these populations need immediate measures to protect them. Increased protection measures in such areas should have priority over trade control, given the complexity of the trade network and the lack of government resources to control it. Nevertheless, for long-term conservation goals additional measures such as trade control, environmental education in buffer zones, and raising people's awareness in urban areas, where wildlife consumption has increased, are also required.

Published: December 2007

Over 8 months we surveyed the Lake Tumba landscape, Democratic Republic of Congo, walking 86 km of transects and 324 km of reconnaissance, to document the distribution and estimate the abundance of great apes. Five separate groups of bonobo Pan paniscus were located in the areas of Bolombo-Losombo, Mbala-Donkese, Ngombe-Botuali, Botuali-Ilombe, and Mompulenge–Mbanzi-Malebo–Nguomi, and one population of chimpanzees Pan troglodytes in the Bosobele-Lubengo area. Mean bonobo densities ranged from 0.27 individuals km-2 in the vicinity of Lake Tumba to 2.2 individuals km-2 in the Malebo-Nguomi area. In the latter they appear to be living at a higher density than reported for any other site. This may be due to the area's forest-savannah mosaic habitat, which may provide year-round fruit sources, with bonobos falling back on savannah fruits when forest resources are scarce. The bonobos of the Bolombo-Losombo area and the Bosobele-Lubengo chimpanzees have low relative abundances and live in marginal habitats of islands of terra firma within inundated forests.

Refugees in the UK Labour Market: The Conflict between Economic Integration and Policy-led Labour Market Restriction
Authors: BLOCH ALICE
Published: December 2007

This article draws on data from a survey of 400 refugees and shows low levels of labour market activity. The minority of refugees who are working are in secondary sector jobs with little opportunity for progression. Moreover, refugees with high levels of skills who are working are not in jobs commensurate with their skills and qualifications. The article examines the human capacity and personal characteristics that have an impact on refugee employment, and finds the greatest difference in employment is between men and women, although English language fluency and training are also very important. Employment is a major part of the refugee integration strategy, and employment initiatives focus on capacity-building rather than discrimination or reversing restrictive policies. The article concludes that strategies need to focus on individual employability as well as measures to overcome personal and structural barriers to the labour market.
Neighbourhood Ethnic Concentration and Discrimination
Authors: MAGEE WILLIAM , FONG ERIC , WILKES RIMA
Published: December 2007

We investigate the association between the residential concentration of Chinese in Toronto and discrimination as experienced and perceived by Chinese immigrant residents. A unique aspect of this study is our focus on perceived employment discrimination. We find that Chinese immigrants living in neighbourhoods with a high concentration of other Chinese residents are more likely to perceive employment discrimination against Chinese people as a group, and are more likely to report exposure to ethnically motivated verbal assault, than are Chinese immigrants living elsewhere. Our results are consistent with studies of other populations. However, we argue that theory and policy related to ethnic concentration and discrimination should recognise that effects of ethnic concentration on discrimination are likely to vary with the ecological setting under investigation (for example, neighbourhoods versus larger areas), as well as by size of locale (city, region, or country), and the ethnic groups involved.
Lower Prices Improve Diversity in the Performing Arts: Is This True and Does It Matter?
Authors: BORGONOVI FRANCESCA
Published: December 2007

Participation and attendance in the arts can foster social capital, economic regeneration and skill acquisition. For these reasons, encouraging greater arts participation and attendance among disadvantaged groups became part of the New Labour strategy to promote neighbourhood renewal and tackle social exclusion. It is, however, far from clear what policies are best suited to achieve the aim of greater involvement in the arts. One policy option is to award subsidies to lower admission fees. Using 14 years of data from the UK Family Expenditure Survey, the article examines whether lower prices stimulate attendance at live performances overall and among low-income groups in particular. Findings indicate that while ticket prices influence attendance generally, the response of different income groups is similar, with a 10 per cent increase in price accompanied by a 9 per cent drop in demand. This means that, while price controls may be effective in increasing overall attendance levels among all groups in the population, including among low-income groups, they may not prove adequate whenever the main aim is to reduce the gap in participation across social groups.
Policy Interaction: The Mixing of Fatherhood, Crime and Urban Policies
Authors: JORDAN-ZACHERY JULIA S.
Published: December 2007

In an attempt to counter changes in family structures, a number of nation states are designing policies to make men fit into families. In the case of the USA, decision makers view fatherhood and marriage as the cure for poverty among African Americans. To assert that training these men to be better fathers and husbands will help them improve other dimensions of their lives (particularly poverty) is a good idea, but it is also simplistic. Decision makers rely on an intra-group, which privileges an individualistic and cultural approach, in their development of policies. This approach tends to ignore that other subsystems, such as previously existing policies, can have an impact on the effectiveness of marriage and fatherhood promotion. Using the USA as a case study, I hypothesise that the effectiveness of fatherhood and marriage promotion is limited because of their interaction with other policies. Fatherhood and marriage promotion initiatives will be negatively affected by the absence of a progressive national urban policy, particularly in the area of economic development and in the context of current crime policies. The socio-economic and cultural reality faced by African American men must be incorporated into the decision-making processes in order to identify the most effective policies.
Flexicurity in Bismarckian Countries? Old Age Protection for Non-standard Workers in Belgium
Authors: PEETERS HANS , DEBELS ANNELIES , VERSCHRAEGEN GERT , BERGHMAN JOS
Published: December 2007

In the debate on ‘flexicurity’, relatively little attention has been paid to how responsive traditional areas of social security have been to increasing flexibility in the labour market. This article tries to fill this gap by focusing on the Belgian pension system. In particular, it asks to what extent pension regulation in the three pillars has been adapted to the proliferation of atypical forms of employment. It does so by examining whether there are significant differences between old age protection of standard and non-standard workers. The article pursues a double research strategy: an analysis of Belgian legislation and relevant collective labour agreements is complemented with a statistical analysis of the Panel Study of Belgian Households (PSBH). The results show that part-time employment results in a lower first-pillar pension, while other forms of temporal flexibility such as career interruptions and temporary unemployment do not. In the second pillar, our findings suggest that workers with contractual flexibility and job mobility are discriminated against. Finally, non-standard workers do not appear to compensate for lower pension protection through increased participation in the third pension pillar. Our findings suggest the need for a re-assessment of the system of ‘assimilated’ periods. To conclude, we point to some implications for the design of flexicurity policies.
The Pursuit of a Canonical Definition of Membership of the Church of Ireland
Authors: Colton Paul
Published: December 2007

This paper pursues a canonical definition of membership of the Church of Ireland. Both civil and Church laws presuppose that membership is defined; clergy rely on definitions, both formal and informal. In Ireland, freedom of religion is guaranteed and the courts are reluctant to interfere in the internal affairs of religious entities. Churches are voluntary associations, and church members are bound, inter se, by the church's internal laws as a matter of contract; this is given statutory expression in the Irish Church Act 1869. While the law of the Church of Ireland presents no unified definition of membership, the concept is utilised: strata of membership are manifest in a multiplicity of terminologies and roles. In the dynamics discerned in Church laws (not least the Preamble and Declaration and the Constitution of the Church of Ireland) a nascent definition of membership is detected. Comparison with the Anglican Communion and the ecumenical arena exposes weaknesses in the laws of the Church of Ireland. History indicates that membership was recognised and relied on in an establishment context, but not defined. In this paper, an anatomy of a canonical definition of membership that transcends such self-defining models is posited, based on the proposition that membership is more than what people say they are.
Use of natural and anthropogenic resources by Olrog's Gull Larus atlanticus: implications for the conservation of the species in non-breeding habitats
Authors: Berón María Paula , Favero Marco , Laich Agustina Gómez
Published: December 2007

We studied the exploitation of crab-beds and fishing grounds by Olrog's Gulls Larus atlanticus in non-breeding areas along the coast of Buenos Aires province, Argentina. During 2004 and 2005, censuses were performed in different areas of Mar Chiquita coastal lagoon and Mar del Plata harbour. Additionally, from April to August 2005 the movements of five non-breeding individuals were studied by means of radio-telemetry. At both study sites the highest numbers of Olrog's Gulls were observed between June and August. A total of 278 radio-tracked locations (from 407 samples) were registered. All the tracked individuals showed strong site fidelity, with 96% of the radio signals registered in the vicinity of the lagoon's mouth, associated with both crab-beds and areas where sport-fishing activities took place. Conservation issues in non-breeding areas should be tackled in the near future, given the conservation status of this species (Vulnerable) and the fact that each year several Olrog's Gulls are being killed because of their interaction with sport-fishing activities.

Resumo

Se estudió la utilización de cangrejales y áreas de pesca por la Gaviota de Olrog durante el periodo no reproductivo. Durante los aãos 2004 y 2005 se realizaron censos en diferentes áreas de la Laguna Costera Mar Chiquita y el Puerto Mar del Plata, Provincia de Buenos Aires, Argentina. En ambos sitios de estudio el mayor número de individuos se observó entre los meses de junio y agosto. Adicionalmente entre los meses de abril y agosto de 2005 se estudiaron los movimientos de cinco individuos no reproductores mediante el uso de radio-transmisores. De un total de 407 muestras se obtuvieron 278 localizaciones. Todos los individuos instrumentados mostraron una alta fidelidad al sitio. El 96% de las localizaciones se registraron en cercanías de la desembocadura de la laguna, asociadas a cangrejales y areas de pesca deportiva. Considerando el estatus de conservación de la Gaviota de Olrog (‘Vulnerable’) y los efectos negativos de su interacción con la pesca deportiva, programas de conservación en áreas no reproductivas deben ser implementados.
