Spawning Behaviors in the Bluehead Chub, Nocomis leptocephalus, River Chub, N. micropogon and Central Stoneroller, Campostoma anomalum

Abstract Spawning behaviors were filmed and observed in the nest-building minnows, the bluehead chub, Nocomis leptocephalus, and river chub, N. micropogon. Analysis of videotapes exposed previously unreported behaviors (e.g., female retroflexure) and a precise sequence of male-female interactions that coordinated a successful spawn. Reproductive behaviors were classified into six sequential categories (interim, approach, alignment, run, clasp, dissociation) to facilitate interspecific comparisons. The most conspicuous differences between species involved the intensity of the female's retroflexure and the male's spawning clasp (strong in N. leptocephalus vs. weak in N. micropogon) and reproductive behaviors of subordinate males. In N. leptocephalus, subordinate males spawned concurrently and independently of the resident male over a communal nest, whereas in N. micropogon a subordinate acted like a satellite male and stole spawns from the nest-building male. In addition, heterogeneric spawning clasps involving a male and female N. leptocephalus and a male central stoneroller, Campostoma anomalum, are newly described.
Short term effects of wild fire on invertebrates in coastal heathland in southeastern Australia

Differences in the assemblages of terrestrial arthropod communities in burnt and adjacent unburnt areas of coastal heathland are reported. The burnt site experienced a wildfire 20 months prior to sampling. Collections of invertebrates from pitfall traps in winter indicated that there was no difference in total species richness or total numbers of individuals trapped between burnt and unburnt plots. However, at species level, 60 percent of the taxa showed a strong preference for either burnt areas or unburnt areas with only a few species trapped in around equal numbers in both areas. Twenty percent of species were only found on the unburnt plots. The implications of these results for fire management are discussed.
Activation of Protein Kinase Cδ by IFN-γ1

Engagement of the type II IFN (IFN-γ) receptor results in activation of the Janus kinase-Stat pathway and induction of gene transcription via IFN-γ-activated site (GAS) elements in the promoters of IFN-γ-inducible genes. An important event in IFN-γ-dependent gene transcription is phosphorylation of Stat1 on Ser727, which is regulated by a kinase activated downstream of the phosphatidylinositol 3′-kinase. Here we provide evidence that a member of the protein kinase C (PKC) family of proteins is activated downstream of the phosphatidylinositol 3′-kinase and is engaged in IFN-γ signaling. Our data demonstrate that PKCδ is rapidly phosphorylated during engagement of the type II IFNR and its kinase domain is induced. Subsequently, the activated PKCδ associates with a member of the Stat family of proteins, Stat1, which acts as a substrate for its kinase activity and undergoes phosphorylation on Ser727. Inhibition of PKCδ activity diminishes phosphorylation of Stat1 on Ser727 and IFN-γ-dependent transcriptional regulation via IFN-γ-activated site elements, without affecting the phosphorylation of the protein on Tyr701. Thus, PKCδ is activated during engagement of the IFN-γ receptor and plays an important role in IFN-γ signaling by mediating serine phosphorylation of Stat1 and facilitating transcription of IFN-γ-stimulated genes.
Overview of 1-Methylcyclopropene Trials and Uses for Edible Horticultural Crops

The inhibitor of ethylene perception, 1-methylcyclopropene (1-MCP), is the basis of a new technology that is increasingly being used to improve storage potential and maintain quality of fruit and vegetables. 1-MCP is registered for use on a number of crops, including apple, apricot, avocado, banana, broccoli, kiwifruit, pear, mango, melon, peach, nectarine, persimmon, plum, and tomato. Theregistered crop is often specificto country. The effectsof 1-MCP onquality of thesecrops,aswellasitseffectsonphysiologicaldisordersandpathological diseases,arereviewed.Mostavailableliterature on 1-MCP has focused on laboratory-based trials and little information exists about its effects on product quality at the commercial level. The apple is the most significant exception, being the first crop for which 1-MCP was used commercially and extensively around the world. The apple is a crop for which limited ripening after harvest is desirable. For many other fruit, successful commercialization of 1-MCP will require an appropriate balance between 1-MCP concentrations and exposure periods that will delay but not inhibit ripening. The effects of preharvest factors, cultivar, maturity, and postharvest practices are complex and will impact commercial success of 1-MCP-based technology. For leafy or nonfruit vegetables, the advantages of 1-MCP may only be apparent under abusive conditions such as high temperatures and exogenous ethylene exposure. Finally, commercial utilization of 1-MCP-based technology will be a function of the cost of its application relative to its benefits for each product.
Effects of no-take area size and age of marine protected areas on fisheries yields: a meta-analytical approach

Marine protected areas (MPAs) are often promoted as tools for biodiversity conservation as well as for fisheries management. Despite increasing evidence of their usefulness, questions remain regarding the optimal design of MPAs, in particular concerning their function as fisheries management tools, for which empirical studies are still lacking. Using 28 data sets from seven MPAs in Southern Europe, we developed a meta-analytical approach to investigate the effects of protection on adjacent fisheries and asking how these effects are influenced by MPA size and age. Southern European MPAs showed clear effects on the surrounding fisheries, on the ‘catch per unit effort’ (CPUE) of target species, but especially on the CPUE of the marketable catch. These effects depended on the time of protection and on the size of the no-take area. CPUE of both target species and the marketable catch increased gradually by 2‐4% per year over a long time period (at least 30 years). The influence of the size of the no-take area appeared to be more complex. The catch rates of the entire fishery in and around the MPA were higher when the no-take areas were smaller. Conversely, catch rates of selected fisheries that were expected to benefit most from protection increased when the no-take area was larger. Our results emphasize the importance of MPA size on its export functions and suggest that an adequate, often extended, time frame be used for the management and the evaluation of effectiveness of MPAs.
The deep divergences of neornithine birds: a phylogenetic analysis of morphological characters

Consensus is elusive regarding the phylogenetic relationships among neornithine (crown clade) birds. The ongoing debate over their deep divergences is despite recent increases in available molecular sequence data and the publication of several larger morphological data sets. In the present study, the phylogenetic relationships among 43 neornithine higher taxa are addressed using a data set of 148 osteological and soft tissue characters, which is one of the largest to date. The Mesozoic non‐neornithine birds Apsaravis, Hesperornis, and Ichthyornis are used as outgroup taxa for this analysis. Thus, for the first time, a broad array of morphological characters (including both cranial and postcranial characters) are analyzed for an ingroup densely sampling Neornithes, with crown clade outgroups used to polarize these characters. The strict consensus cladogram of two most parsimonious trees resultant from 1000 replicate heuristic searches (random stepwise addition, tree‐bisection‐reconnection) recovered several previously identified clades; the at‐one‐time contentious clades Galloanseres (waterfowl, fowl, and allies) and Palaeognathae were supported. Most notably, our analysis recovered monophyly of Neoaves, i.e., all neognathous birds to the exclusion of the Galloanseres, although this clade was weakly supported. The recently proposed sister taxon relationship between Steatornithidae (oilbird) and Trogonidae (trogons) was recovered. The traditional taxon “Falconiformes” (Cathartidae, Sagittariidae, Accipitridae, and Falconidae) was not found to be monophyletic, as Strigiformes (owls) are placed as the sister taxon of (Falconidae + Accipitridae). Monophyly of the traditional “Gruiformes” (cranes and allies) and ”Ciconiiformes” (storks and allies) was also not recovered. The primary analysis resulted in support for a sister group relationship between Gaviidae (loons) and Podicipedidae (grebes)—foot‐propelled diving birds that share many features of the pelvis and hind limb. Exclusion of Gaviidae and reanalysis of the data set, however, recovered the sister group relationship between Phoenicopteridae (flamingos) and grebes recently proposed from molecular sequence data.
POPULATION VARIATION IN ESCAPE BEHAVIOR AND LIMB MORPHOLOGY OF COLLARED LIZARDS (CROTAPHYTUS COLLARIS) IN OKLAHOMA

The evolution of the morphological traits underlying locomotor performance is often addressed at the level of species comparisons; however, examining variation in traits within a species and the underlying selective pressures that presumably mold those traits can offer great insight into the effects of natural selection, as well as the selective forces responsible for phenotypic changes. We studied limb morphology and escape behavior of three Oklahoma populations of collared lizards: Glass Mountains (GM), Sooner Lake (SL), and Wichita Mountains (WM). Predation differs among populations, with WM > SL ≫ GM. Habitat openness also varies, with SL > GM > WM. Our analysis of limb morphometrics revealed that WM had the longest hindlimb elements, GM lizards had the shortest, and SL lizards were intermediate. These differences are consistent with the hypothesis that predation pressure rather than habitat structure is most important in determining hindlimb morphology. WM lizards were found to have the longest approach distance among populations, but GM lizards ran the longest distances from predators. These differences in escape behavior support the hypothesis that predation pressure is important in determining population differences in behavior.
TET2 Mutations in Ph-Negative-Myeloproliferative Neoplasms: Identification of Three Novel Mutations and Relationship with Clinical and Laboratory Findings

High-throughput DNA sequence analysis was used to screen for TET2 mutations in peripheral blood derived DNA from 97 patients with BCR-ABL-negative-myeloproliferative neoplasms (MPNs). Overall six mutations in the coding region of the gene were identified in 7 patients with an overall mutational frequency of 7.2%. In polycythemia vera patients (n = 25) were identified 2 mutations (8%); in those with essential thrombocythemia (n = 55) 2 mutations (3.6%); in those with unclassifiable MPN (n = 8) 3 mutations (37.5%). No primary myelofibrosis patiens (n = 6) harboured TET2 mutations. Three unreported mutations were identified (p.P177fs, p.C1298del, p.P411del) the first two in patients with unclassifiable MPN, the last in a patient with essential thrombocythemia. On multivariate analysis the diagnosis of an unclassifiable MPN was significantly related to the presence of TET2 mutations (p = 0.02; OR: 2.81; 95% CI 1.11 - 7.06). We conclude that TET2 mutations occur in both JAK2V617F-positive and -negative MPN and are more frequent in MPN-U patients. This could represent the biological link between the different classes of myeloid malignancies.
Systematics of Podocoma (Asteraceae: Astereae): a generic reassessment

Podocoma is a southern South American genus of perennial herbs with short-radiate capitula with two- to four-seriate ray florets and a two- to three-seriate pappus of scabridulous setae. The ray florets have corollas with narrow limbs. The rostrate cypsela of Podocoma is one of the most distinct features of the genus. Podocoma, with many of the endemic southern South American genera of Astereae, is included in subtribe Podocominae. Podocoma traditionally contained seven mainly Brazilian species (P. asperrima, P. bellidifolia, P. blanchetiana, P. hieracifolia, P. hirsuta, P. regnellii and P. spegazzinii), and its expansion to include two species of Conyza (C. notobellidiastrum and C. rivularis) was, perhaps, the most significant recent change in the generic concept of Podocoma. However, recent molecular- and morphology-based phylogenetic analyses do not support the inclusion of these two species in Podocoma. Morphological and anatomical studies were carried out in order to clarify the taxonomy of Podocoma and to delimit the genus and its species. On the basis of the results of these morphological and anatomical studies, and those from molecular- and morphology-based phylogenetic analyses, P. notobellidiastrum and P. rivularis are excluded from Podocoma and transferred to a new genus that is currently under description. Moreover, P. regnellii and P. asperrima are placed in synonymy with P. hirsuta and P. spegazzinii, respectively. Three species, P. bellidifolia, P. blanchetiana and P. hieracifolia, are recognized here as a complex of closely related species from a morphological point of view; however, they are treated separately. © 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 163, 486–513.
Effect of bio-fertilizers on groth and yield of chilli ( Capsicum annuum L.) cv Byadagi Dabba at different levels of nitrogen and phosphorus

Investigations were carried out to study the effect of nitrogenous and phophatic bio-fertilizers along with different levels of nitrogen and phosphorus on growth and yield of chillies (Capsicum annuum) cv Byadagi Dabba. The maximum plant height, leaf area per plant and dry matter production per plant were in the treatment supplied with 75% N, P plus 100% K in addition to the inoculation of Azotobacter, Azospirillum, phosphate solubilizing bacteria (PSB) and vesicular arbuscular mycorrhiza (VAM). The plants inoculated with Azotobacter, Azospirillum, PSB and VAM along with 75% N, P plus 100% Kproduced more number of fruits per plant and higher yield of dry chillies. Application of bio-fertilizers along with reduced level of chemical fetilizers has beneficial effect compared to application of chemical fertilizers or bio-fertilizers alone.
Using opportunistic photo-identifications to detect a population decline of killer whales (Orcinus orca) in British and Irish waters

An assemblage of killer whales that has been sighted in waters off the west coast of the British Isles and Ireland has previously been shown to be isolated from other North Atlantic killer whale communities based on association patterns. By applying a Bayesian formulation of the Jolly–Seber mark-recapture model to the photo-identification data compiled from opportunistic photographic encounters with this population of killer whales, we show that such sparse and opportunistically-collected data can still be valuable in estimating population dynamics of small, wide-ranging groups. Good quality photo-identification data was collected from 32 encounters over 19 years. Despite a cumulative total of 77 identifications from these encounters, just ten individuals were identified and the remaining 67 identifications were re-sights of these ten animals. There was no detected recruitment through births during the study and, as a result, the population appears to be in a slight decline. The demography of the population was highly skewed towards older individuals and had an unusually high ratio of adult males, and we suggest that demographic stochasticity due to a small population size may be further impacting the population growth rate. We recommend that this population be managed as a separate conservation unit from neighbouring killer whale populations.
Molecular Phylogeny of the Tree‐of‐Heaven Family (Simaroubaceae) Based on Chloroplast and Nuclear Markers

Members of Simaroubaceae comprise a clade of 22 genera and ca. 100 species in the Sapindales. Previous phylogenetic analyses of the family were limited to a single gene and seven genera, and relationships among the genera remain poorly understood. Molecular data from three plastid genes (rbcL, atpB, and matK) and a nuclear gene (phyC), totaling ca. 6000 bp, are used to reconstruct the phylogeny of Simaroubaceae and clarify generic limits, employing maximum parsimony (MP) and Bayesian approaches. Individual analyses of genes are largely congruent, and both MP and Bayesian analyses of combined data produce well‐supported phylogenies. Nothospondias, an African genus of uncertain affiliation, is found to be a member of the family. A clade composed of Picrasma, Holacantha, and Castela is sister to the rest of the family, and enigmatic Leitneria is sister to a clade of Brucea, Soulamea, and Amaroria. A broad circumscription of Quassia is unwarranted given several well‐supported clades corresponding to traditional generic limits. Comparisons among Bayesian analyses, partitioned variously by gene and codon position, reveal that the most complex method of partitioning best explains the data under a Bayes factor criterion. However, tree topology did not change among partitioning strategies, suggesting that the phylogenetic signal is robust and resistant to model misspecification.
Morphology and Development of the Immature Stages of Brachyufens Osborni (Hymenoptera: Trichogrammatidae), an Egg Parasitoid of Broad-Nosed Weevil Species (Coleoptera: Curculionidae)

ABSTRACT The external morphology and development of the immature stages of Brachyufens osborni (Dozier) (Hymenoptera: Trichogrammatidae), a Nearctic solitary endoparasitoid of the eggs of Pachnaeus spp. (Coleoptera: Curculionidae), are reported. Under our laboratory conditions (25°C and a photoperiod of 12:12 [L:D] h), B. osborni reared in eggs of Pachnaeus litus (Germar) (Entiminae) had a developmental time of 14.7 d. Egg hatching occurred within 15 h from oviposition and mandible measurements indicated the existence of two instars. First instars were mymariform, whereas second instars were sacciform. Pupation occurred 5–6 d after egg hatching and adults emerged 8 d later. On completion of the preimaginal development, the meconium was expelled and emergence took place by biting a hole in the chorion of the host egg. Both sexes emerged at the same time, and the sex ratio was female biased (3:1).
Reproductive cycle of the traditionally exploited sea cucumber Holothuria tubulosa (Holothuroidea: Aspidochirotida) in Pagasitikos Gulf, western Aegean Sea, Greece

The reproductive cycle of the traditionally exploited sea cucumber Holothuria tubulosa was investigated in the Pagasitikos Gulf (39°18'457\"N, 23°05'869\"E) from June 2007 to July 2008. The study examined the microscopic characteristics of the gonads and was based on maturity index (MI) and oocytes' size-frequency distribution. The reproductive cycle was found to be synchronous between sexes, following an annual pattern. The minimum MI values were recorded in December and January, marking the onset of the reproductive cycle. During the spring, MI increased due to gamete development and proliferation. Mature specimens were prominent in summer while spawning occurred between July and September. The maximum MI values were recorded in mid-autumn, when most specimens were at the postspawning stage. The oocytes' size-frequency distribution showed analogous seasonal variability. The present findings are crucial for establishing an efficient management strategy for this commercial and ecosystem-engineering species, since its exploitation in Greek waters has not been under official control for more than a century. The authors propose a seasonal ban on the exploitation of the species from July to September and a minimum individual drained weight limit of 250 g.
The Ecology of Bird Introductions

A growing number of species have been transported and introduced by humans to new locations and have established self-sustaining wild populations beyond their natural range limits. Many of these species go on to have significant environmental or economic impacts. However, not all species transported and introduced to new locations succeed in establishing wild populations, and of the established species only some become widespread and abundant. What factors underlie this variation in invasion success? Here, we review progress that has been made in identifying factors underpinning invasion success from studies of bird introductions. We review what is known about the introduction, establishment, and spread of introduced bird species, focusing on comparative studies that use historical records to test hypotheses about what factors determine success at different stages in the invasion process. We close with suggestions for future research.
Anther Culture in Rye: Improved Plant Regeneration Using Modified MS‐Media

The use of androgenetic doubled haploids in rye breeding is still limited by low regeneration rates. In this study we tested the influence of two modified MS-media on the number of reacting anthers and on plant regeneration. Picloram and 2,4-D were used as auxin components in the induction media. The highest induction rates (reacting anthers per 100 cultivated anthers) and the highest regeneration rates (number of green plants per 100 cultivated anthers) were reached on a modified MS-medium containing Picloram as auxin source, regardless of the donor plant material. The comparison of the results obtained with the single cross ‘SC 35’ which contains genes of Secale vavilovii and the true Secale cereale donor forms clearly show the genotypic influence of donor plant material on induction and regeneration ability.
Nutritional Compositions in Edible Portion of Castanopsis cuspidata Seeds

Dept. of Culinary Art, Chodang University, Jeonnam 534-701, KoreaAbstractNutritional compositions in edible portion of Castanopsis cuspidata seeds were investigated. Moisture content of Castanopsis cuspidata was 24.72 (Wt. %), crude protein was 2.19% (Wt. %), crude lipid was 0.83% (Wt. %), ash was 1.04% (Wt. %), and carbohydrate was 52.63% (Wt. %) in Castanopsis cuspidata seeds. Major amino acids were glutamic acid, aspartic acid, arginine and histidine, and minor ones were alanine, serine, proline, and valine. Sucrose was the highest content of free sugar in the seed. Major fatty acids were linolenic acid (18:3), palmitic acid (16:0) and oleic acid (18:1). Major minerals were P, K, Mg, Zn and Ca at the level of 88.31, 26.00, 13.20, 10.90, and 3.93 mg/100 g, respectively.Key words: Castanopsis cuspidata seeds, amino acids, free sugar, fatty acids, minerals
