Finding new instrumental rheological parameters that better describe sensory textures can improve correlation between rheological and sensory measurements of food. Two optical three‐dimensional (3‐D) techniques commonly used in mechanical engineering field were studied. These techniques have never been used in food science. Digital image correlation and Breuckmann scanning systems were successful to distinguish gelatin gels and soft cheeses varying in firmness and viscoelastic properties. These two systems were coupled with a universal testing machine to provide information regarding 3‐D displacements and surface deformation of sample. Mathematical models were developed to determine surface displacement profiles of samples from their firmness and viscoelastic properties. Three parameters were obtained to describe surface displacement profiles linked to samples textural properties. These parameters may be useful to develop models predicting accurately food sensory texture from instrumental measurements.

T‐shaped malformation of the ventral colon in a Thoroughbred filly with colic
Authors: Trope GD , Steel CM
Published: July 2010

A 4‐month‐old Thoroughbred filly presented for abdominal pain was diagnosed with a T‐shaped malformation of the ventral colon at exploratory laparotomy. Following resection and anastomosis of the large colon, no further episodes of abdominal pain occurred during a 12‐month follow‐up. Acute dehiscence of the linea alba occurred as a complication of the initial laparotomy, but was successfully managed following additional surgical repair. T‐shaped malformation of the ventral colon has not previously been reported and is considered a congenital malformation of mesocolon formation.
Seroconversion to avian influenza virus in free‐range chickens in the Riverland region of Victoria

Published: July 2010

Background  Since 2005, H5N1 avian influenza (AI) has spread from South‐East Asia to over 60 different countries, resulting in the direct death or slaughter of over 250,000,000 poultry. Migratory waterfowl have been implicated in this spread and in Australia there have been numerous isolations of low‐pathogenicity AI virus from wild waterfowl and shorebirds. The Department of Human Services, Victoria maintains 10 sentinel free‐range chicken flocks in the Riverland at locations that are populated by large numbers of waterfowl known to carry a range of strains of AI.

Objective  This study analysed historical samples collected in 1991–94 and 2003–06 from the library of serum samples for antibodies against AI to assess the potential for transfer of AI virus from wild waterfowl to free‐range poultry.

Results  Of the 2000 serum samples analysed, 17 were positive for antibodies against AI and 87 were suspect, with a clustering of positive and suspect results in the years 1994, 2003 and 2004. There was also a clustering of positive samples at the site of the Barmah flock. Nine sequential sets of sera from individual chickens with at least one positive result were identified. Analysis of these sequential sets showed that infection was acquired on site but that the antibody response to AI infection was short‐lived and was no longer detectable at 8 weeks after the positive finding.

Conclusion  The surveillance of sentinel chickens is a potential avenue for monitoring the circulation of AI viruses and could provide an early warning system for the commercial poultry industries.

This study was performed to test whether morning hypertension defined by the morning‐evening difference in home blood pressure (BP) (MEdif) and the average of morning and evening BP (MEave) is a determinant of concentric left ventricular hypertrophy (LVH). The authors enrolled patients with untreated hypertension and performed echocardiography and home BP monitoring for 14 consecutive days. All patients were classified into 4 groups by the MEave and MEdif and morning hypertension was defined by MEave ≥135 mm Hg and MEdif ≥15 mm Hg. Left ventricular (LV) geometry was classified as normal, concentric remodeling, eccentric LVH, or concentric LVH. The morning hypertensive patients had a higher LV mass index and relative wall thickness than the other groups. According to multivariable logistic regression analysis, morning hypertensive patients had a significantly increased risk of the concentric LVH (odds ratio, 6.5; 95% confidence interval, 2.5–17.2; P<.001) compared with home normotensive patients with MEdif <15 mm Hg, after adjusting for confounders. Moreover, even among the home normotensives (white‐coat hypertensives), patients with MEdif ≥15 mm Hg had a higher percentage of concentric remodeling than those with MEdif <15 mm Hg (32.5% vs 14.7%, P=.017). Morning hypertension defined by the MEdif and MEave is a strong determinant of concentric LVH, suggesting that this definition could be used to determine the cardiovascular risk of morning hypertension.
Internet‐based assessment of medical students’ ophthalmoscopy skills
Authors: Åsman Peter , Lindén Christina

Acta Ophthalmol. 2010: 88: 854–857

Purpose:  Ophthalmoscopy is an important skill in undergraduate medical education. The use and outcome of a novel Internet‐based method for assessing motor skills‐related aspects of ophthalmoscopy skills in medical students are described.

Methods:  A total of 139 students in Malmö and 255 students in Umeå were assessed during four consecutive semesters. An optic disc photograph was obtained in each student. At assessment each student was asked to examine the eye of a fellow student. Fifteen disc photographs were displayed on a computer screen. One of the photographs was from the fellow student. The remaining images had been randomly selected. The student was asked to identify the optic disc of the fellow student from the 15 photographs on the screen. In one semester, the time spent on this by each student was recorded.

Results:  All students completed the task. The average pass ratio was 96.4% (ranging from 94.0% to 98.0%). Median student times were 5.53 mins in Malmö and 6.36 mins in Umeå.

Conclusions:  This is the first automated, Internet‐based assessment of an ophthalmic motor skill performed in co‐operation between universities. The method used bears more similarities to real‐life ophthalmoscopy than methods that use model eyes. Time investments and infrastructure demands were comparatively low. The method was designed for stand‐alone assessment of ophthalmoscopy or as an objective structured clinical examination station, but it may also be used during the learning process. The collaboration between universities was easily transformed into routine practice and similar projects should be encouraged to increase the standardization of assessment.
All-inorganic thermal nanoimprint process
Authors: Weiss Dirk N. , Meyers Stephen T. , Keszler Douglas A.
Published: July 2010

The authors describe a nanoimprint method for an all-inorganic resist material, aluminum oxide phosphate. The resist is free of organic additives, water-based, environmentally benign and yields dense, amorphous, crack-, and pore-free films after annealing at 300 °C. They achieved macroscopically defect-free imprinted areas of up to 25 cm2, using flexible ethylene tetrafluoroethylene imprint molds. It is shown that, if temperature and pressure are chosen such that the residual solvent in the resist stays liquid during imprinting, macroscopically defect-free imprints can be obtained. Volumetric shrinkage due to postimprint annealing is characterized. The imprinting tests are performed on standard thermal nanoimprint equipment, but the process is believed to be scalable for large-area imprinting.

MESSENGER's Third Set of Messages

The temporal extent of volcanic activity and, in particular, the timing of most recent activity had been missing ingredients in the understanding of Mercury's global thermal evolution.

The planet's tail magnetic field increased and then decreased by factors of 2 to 3.5 during periods lasting 2 to 3 minutes. These observations suggest that magnetic open flux loads the magnetosphere, which is subsequently unloaded by substorms—magnetic disturbances during which energy is rapidly released in the magnetotail. At Earth, changes in tail magnetic field intensity during the loading/unloading cycle are much smaller and occur on much longer time scales.

Differences in the altitude profiles of magnesium, calcium, and sodium over the north and south poles of Mercury indicate that multiple processes are at play to create and maintain the exosphere.

Toward a General Flu Vaccination

Current seasonal influenza virus vaccines are targeted against specific viral strains and do not provide broad, durable protection. Seasonal influenza vaccines induce protective antibody responses against regions of viral hemagglutinin (HA) that rapidly mutate so that very soon, the virus becomes resistant to vaccination. Conserved regions of HA also exist, and a major goal of influenza vaccine development is to design a vaccine that elicits antibodies against the conserved regions so that protection against a wide range of viral strains is achieved.

Wei
et al.

Doms

) show that a combined HA DNA prime, followed by boosting with a seasonal vaccine, elicits broadly cross-reactive neutralizing antibody responses in mice, ferrets, and nonhuman primates, which were protective in mice and ferrets against heterologous influenza challenge. The neutralizing antibodies were directed against the conserved HA stem region, which indicates the possibility that a more broadly protective vaccine against influenza could be developed.
ARTIFICIAL NEURAL NETWORK PREDICTION FOR THERMAL DECOMPOSITION OF POTASSIUM NITRATE (KNO3) AND BENZOIC ACID (C6H5COOH)
Authors: BEKEN MURAT
Published: July 2010

The aim of this work is to correlate the results of experimental data by using the differential thermal analysis (DTA) method and predictions of artificial neural networks (ANNs). Thermal decomposition of potassium nitrate ( KNO 3) and benzoic acid ( C 6 H 5 COOH ) have been analyzed by the simultaneous DTA method. Kinetic parameters (critical points, the change of enthalpy) have been investigated. A computer model, based on multilayer feed-forwarding back-propagation is used for the prediction of critical points, phase transitions of potassium nitrate ( KNO 3) and benzoic acid ( C 6 H 5 COOH ). As a result of our study, we conclude that the ANN model shows a considerably good result about the prediction of experimental data.
THEORETICAL STUDIES ON THE GYROMAGNETIC FACTORS FORFe3+INZnX(X=O,S,Se,Te)
Authors: WANG XUE-FENG , WU SHAO-YI , XU PEI , LI LI-LI
Published: July 2010

The gyromagnetic factors for Fe3+in ZnX ( X = O , S , Se , Te ) are theoretically studied from the perturbation formula of the g-factor for a 3d5ion in tetrahedra based on inclusion of both the crystal-field and the charge-transfer contributions. The related model parameters in the calculations are determined from the cluster approach in a uniform way. The g-shift Δg (= g-gs, where gs≈ 2.0023 is the spin-only value) from the charge-transfer contributions is opposite (positive) in sign and much larger in magnitude as compared with that from the crystal-field ones. The importance of the charge-transfer contributions increases rapidly with increasing the covalency and the spin-orbit coupling coefficient of the ligand and thus exhibits the order of O2-< S2-< Se2-< Te2-. The calculated g-factors by considering both the crystal-field and charge-transfer contributions show reasonable agreement with the experimental data for all the Fe3+centers in ZnX .
EFFECT OF SINTERING TEMPERATURE ON THE STRUCTURAL AND DIELECTRIC PROPERTIES OF ZINC CADMIUM FERRITES PREPARED BY EGG-WHITE TECHNIQUE
Authors: DAR M. ABDULLAH , SIDDIQUI W. A. , ALAM M.
Published: July 2010

The effect of cadmium substitution and sintering temperature on the microstructure and dielectric properties of nano ZnCd x Fe 2-x O 4 ferrites (x=0.0, 0.05, 0.1, 0.2, 0.3 and 0.5) has been investigated and prepared by egg-white technique. Electrical conductivity and dielectric measurements have been analysed in the frequency range from 100 Hz to 10 MHz. The variation of the real (ε′) and imaginary (ε″) part of dielectric constant, AC conductivity (σ AC ) and loss tangent ( tan δ) with frequency has been studied. It follows the Maxwell–Wagner model based on the interfacial polarization in consonance with the Koop's phenomenological theory. It is found that the permittivity of ZnCd x Fe 2-x O 4 ferrites improved and shows a maximum value (~9 × 103) at 100 Hz for the x=0.1 sample.

A note on the nomenclature of some Upper Jurassic dinoflagellate cyst taxa
Authors: Fisher Michael J. , Riley Leslie A.
Published: July 2010

Abstract. In 1980, several new species of dinoflagellate cyst taxa were validly published and named from the Kimmeridge Clay of England as part of a larger study on Kimmeridgian-Valanginian dinoflagellate cyst assemblages (Fisher & Riley, 1980); this study was originally presented at the IV International Palynological Conference, Lucknow in 1976–77. This note, necessitated by the long publication delay and numerous printing errors, comprises taxonomic re-allocations, taking account of subsequent studies (Norris, 1978; Stover & Evitt, 1978; Davey, 1979; Riley, 1979) and corrects inadvertent taxonomic errors.
A revision of mid-Cretaceous textularian foraminifers from Texas
Authors: Loeblich Alfred R. , Tappan Helen
Published: July 2010

Abstract. As Cretaceous species previously placed in Bigenerina, Siphotextularia, and Textularia differ from typical Cenozoic representatives of these genera in having solid non-canaliculate walls, 16 species from the Fredericksburg and Washita Groups (Albian-Cenomanian) of Texas and Oklahoma have been restudied. The new genera Heterantyx with type species H. antonovae sp. nov. and Quasispiroplectammina with type species Spiroplectammina longa are assigned to the family Spiroplectamminidae. A new family Textulariopsidae is proposed for basically biserial taxa with solid walls and includes Plectinella, Textulariopsis, of which two species T. lechriosa and T. texhomensis are new, the reinstated genus Bimonilina, with a new species B. reciprocata, and three new genera, Aaptoioichus, Haimasiella and Minyaichme.
The generic revision of the Reussellids (Foraminiferida)
Authors: Revets Stefan A.
Published: July 2010

Abstract. The study of the apertural complex in the type species of the reussellid genera leads to a reassessment of the classification of these taxa. The genus Reussella has so many characteristics in common with Bulimina that it is reclassified in the Buliminidae. The family Trimosinidae is retained and redescribed to contain the genera Trimosina, Mimosina and Fijiella only. Pyramidina is retained in the Turrilinidae on account of the praebulimine toothplate.The absence of an internal toothplate and the very un-bulimine apertural face in Bifarinella, Chrysalidinella, Cifellia, Finlayina, Orthocerina, Pavonina and Valvohifarina species is the main argument to remove these genera from the Buliminacea and reclassify them in the superfamily Pavoninacea herein proposed.The genus Orthocerina d’Orbigny, 1839 is reinstated and shown to be closely related to Chrysalidinella and Cifellia.The genus Compressigerina is reclassified in the Uvigerinidae, close to Trifarina because of the presence of an apertural neck with toothplate.
Detailed biostratigraphy of the Santonian/Campanian boundary interval in Northern Israel
Authors: Almogi-Labin A. , Eshet Y. , Flexer A. , Honigstein A. , Moshkovitz S. , Rosenfeld A.
Published: July 2010

Abstract. One of the best continuous and fossiliferous Late Santonian-Early Campanian successions in Israel is the approximately 6m thick Kabri section in northern Israel. Its chalky marls were deposited in an outer shelf to upper slope environment with minor depth fluctuations. This Santonian/Campanian interval was studied examining calcareous nannoplankton, palynomorphs, ostracods and benthonic and planktonic foraminifera. The planktonic foraminiferal Dicarinella asymetrica - Globotruncanita elevata concurrent range zone was first observed in Israel in the Kabri section. The first occurrence of Aspidolithus parcus parcus herein is characterized by small specimens, difficult to determine by light microscopy. The lower boundary of the Campanian in this sequence was defined by the first occurrence of G. elevata, in accordance with the ammonite stage definition. This datum line nearly coincides with the first occurrence of the nannofossil marker A. parcus parcus and with the base of the Leguminocythereis dorsocostata (S-4) ostracod zone, both slightly above the foraminiferal boundary.
Exceptional new record of Cretaceous Hauterivian Angiospermid Pollen from Southern England
Authors: Hughes N. F. , Mcdougall A. B. , Chapman J. L.
Published: July 2010

Abstract. Routine SEM examination of a previously neglected part of the Wealden succession in the borehole at Kingsclere, Southern England, has revealed a very well preserved set of specimens, in a single sample (KCE 777), of a type of early pollen grain only known hitherto from isolated grains. This tectate-columellate monosulcate pollen with sharply segmented muri and sturdy columellae is the earliest known with generally accepted angiospermid characters, and appears to be of Cretaceous Hauterivian age. The nature of the simple tectate pattern over the aperture suggests a style of pollen development to bear in mind when searching for even earlier pollen of this group.
Henry Hopley White (1790–1877) and the early researches on Chalk “Xanthidia” (marine palynomorphs) by Clapham microscopists
Authors: Sarjeant William A. S.
Published: July 2010

Abstract. In the mid-nineteenth century, a group of microscopists centred in Clapham, London, made significant early contributions to our knowledge of the fossils then known as ‘Xanthidia’ (and now known to include dinoflagellates, acritarchs and prasinophytes), describing or illustrating many types and formulating far-reaching conclusions concerning their physical character and distribution in sediments. Prominent among them was Henry Hopley White (1790–1877), London barrister and amateur microscopist. An account of White’s life is presented and the morphology and present systematic placement of the forms he described are summarized. The new combinations Eatonicysta? vestita (White) and Achomosphaera? malleofera (White), both dinoflagellates; Tasmanites globosus (White), a prasinophycean; and Comasphaeridium fimbriatum (White), an acritarch, are proposed.
The platycopid signal: a means of detecting kenoxic events using Ostracoda
Authors: Whatley Robin
Published: July 2010

Abstract. It has been shown that during Jurassic and Cretaceous kenoxic events, while other groups of benthonic Ostracoda severely decline and eventually disappear, the Platycopina tend to survive. The survival of the platycopids is attributed to their being filter feeders who, in dysaerobic conditions manage to obtain sufficient oxygen by virtue of the greater volume of water which they circulate across their respiratory surface in the course of their normal feeding behaviour. The podocopid ostracods, which are predators, scavengers and deposit feeders, are unable to survive the diminished oxygen concentrations which characterise these events. The platycopid genus Cytherella is shown to dominate the oxygen mininmum zone in two different parts of the Atlantic at the present day.
A new method for bulk palynological processing of oil-contaminated chalks
Authors: Nørgaard Ingerlise , Rasmussen Anne-Marie , Schiøler Poul , Stouge Svend
Published: July 2010

Abstract. INTRODUCTIONThe application of palynomorphs in well-site dating and correlation within the Upper Cretaceous—Danian Chalk Group of the North Sea, is currently being investigated at the Geological Survey of Denmark. Due to the relatively low abundance of palynomorphs in the chalks, a large sample size (100–300g) is often needed to obtain representative microfloras. Palynological preparation of large chalk samples does, however, create processing problems, especially if the samples derive from oil bearing intervals. The aim of this note is to describe a method developed at the Geological Survey of Denmark to overcome these processing problems.PROBLEMS IN THE PREPARATION OF LARGE CHALK SAMPLES.The problems during the preparation process comprise the following factors: The dissolution of carbonates from 100—300g sized chalk samples with hydrochloric acid causes a vigorous reaction that developes vast amounts of foam. The foam development is usually controlled by spraying alcohol or the more hazardous acetone into the reaction vessel; these solvents reduce the vigorous expansion of the foam by reducing the surface tension of the acid. This procedure, however, demands constant surveillance of the acid treatment, because the effect of the solvents is of short duration. Furthermore, the initial vigorous reaction restricts the use of stronger, more effective hydrofluoric acid concentrations to later parts of the acid treatment process, where the reaction is more calm. In the Danish sector of the North Sea, the main producing reservoir is situated in the Chalk Group. Core samples from the Chalk Group are therefore usually usually oil bearing . . .
On Arcacythere Hornibrook, 1952 (Cytheracea, Ostracoda, Crustacea), a senior synonym of Rockallia Whatley, Frame & Whittaker, 1978
Authors: Ayress M. A.
Published: July 2010

Abstract. The type specimens of Arcacythere chapmani Hornibrook, 1952 (the type species of Arcacythere Hornibrook, 1953; Tertiary, New Zealand) have been re-examined and are shown to have internal carapace features identical to those of Rockallia Whatley, Frame & Whittaker, 1978. Rockallia is known from Cenozoic deep-sea sediments worldwide and from the Oligocene and Miocene of northwestern Europe. The external carapace morphologies of Arcacythere and Rockallia show only minor distribution of the fossae. Rockallia is, therefore, shown to be a subjective junior synonym of Arcacythere. An emended diagnosis of A. chapmani is given.
Lower Triassic (Smithian) conodonts from northwest Pahang Peninsular Malaysia
Authors: Metcalfe I.
Published: July 2010

Abstract. Lower Triassic conodonts are reported from limestones, interpreted as a possible submarine slump, exposed along the new Kuala Lipis -Gua Musang highway, northwest Pahang, Peninsular Malaysia. The co-occurrence of Neospathodus triangularis (Bender), Platyvillosus costatus (Staesch), Neospathodus dieneri Sweet and Platyvillosus hamadai Koike in the fauna indicates a Scythian (late Smithian) age. Platyvillosus hamadai is unknown from the Peri-Gondwana province and its occurrence in the fauna supports a pre-Early Triassic rifting of the Malay Peninsula from Gondwana.
The structure and taxonomic position of Millettia Schubert, 1911 (Foraminiferida)
Authors: Revets Stefan A.
Published: July 2010

Abstract. The study of opened specimens of Millettia species confirms the presence of septula subdividing the individual chambers. Toothplates are present between the individual septular foramina, and the chamber foramen. Polished and etched sections show the test to be bilamellar, but secondary lamination is absent. The toothplates are monolamellar and made up of inner lining, each one continuous with the septula which are formed by doubled-up inner lining. Laterally, the internal chamber walls are covered by a web-like coating of supplementary inner lining, continuous with the septula. X-ray diffraction shows the genus to be calcific. The genus is revised to include M. tessellata, M. limbata and the newly described M. ipsithillae and M. polyxenae. The monotypic Millettiidae are considered incertae sedis within the Rotaliina.
Sequence stratigraphy and eustatic sea-level change: the role of micropalaeontology
Authors: Simmons M. D. , Williams C. L.
Published: July 2010

Abstract. Following the May 1992 meeting in Dijon, which initiated an international project on the “Sequence Stratigraphy of European Basins”, it seems an appropriate time to consider the contribution micropalaeontology can make to the science of sequence stratigraphy. In this short note, we assume that readers are familiar with sequence stratigraphic terminology; if not, see Van Wagoner et al. (1988).WHAT ARE THE CHALLENGES FACING SEQUENCE STRATIGRAPHY?Demonstrating global eustatic sea-level change. We accept that the basic sequence stratigraphy model put forward by Peter Vail and his colleagues (see Van Wagoner et al., 1988 for a summary) is a powerful tool for describing many sedimentary successions, and that the associated eustatic sea-level curve (Haq et al., 1987) has some validity. Our own observations on numerous sedimentary sequences around the world suggest that local and global eustatic events exist, and that relative sea-level curves can be constructed, but it should be remembered that the timing and magnitude of many global eustatic events are still to be established. As most workers in the field will be aware, much of the evidence to support the Haq et al. curve has not been published. The Sequence Stratigraphy of European Basins Project will go some way to rectify this, but it should be borne in mind that there can be an unfortunate tendency to use the Haq et al. curve for dating in its own right - i.e. fitting relative sea-level changes seen in a succession to the curve. If this is done, then the global . . .

Abstract. It is shown that the genus Chiasmolithus as currently understood comprises two discrete lineages. It is proposed that these should be formally recognised as separate genera. A new genus, Sullivania, is described and ten new combinations: S. californica, S. consueta, S. danica, S. edwardsii, S. gigas, S. inconspicua, S. minima, S. nitida, S. titus and Cruciplacolithus oulchyensis are introduced. The speculative evolution in the genera Cruciplacolithus, Sullivania and Chiasmolithus is discussed and illustrated.

The reciprocity between coiling direction and dimorphic reproduction in benthic foraminifera
Authors: Nigam R. , Khare N.
Published: July 2010

Abstract. There are various opinions as to what parameter influences the coiling directions in foraminifera. “Do microspheric and megalospheric generations have different coiling ratios?” is an unanswered question in foraminiferal studies. Per view of this, an attempt is made to study the relationship between mode of reproduction (sexual/asexual) and coiling direction (dextral/sinistral) in the benthic foraminiferal species Rotalidium annectens (Parker & Jones). Proloculus (initial chamber) size is taken as an indicator of changes in reproductive behaviour.The present study is based on the observations made on 17722 specimens of this species from 186 samples, obtained from 3 sediment cores (representing a time span of about 9,500 years) from the shallow water region off Karwar, west coast of India. The results indicate an inverse relationship between mean proloculus size and dextrality (% of dextral forms) which is statistically confirmed. The correlation value (r = −0.57) between the two parameters is above the level of significance at 99% level. Therefore, it is inferred that microspheric generation (smaller proloculus) prefers dextral coiling and coiling in benthic foraminifera appears to be influenced by mode of reproduction.

Emendation of the foraminiferal genus Cribrostomoides Cushman, 1910, and its taxonomic implications
Authors: Jones Robert W. , Bender Heike , Charnock Michael A. , Kaminski Michael A. , Whittaker John E.
Published: July 2010

Abstract. A review of the taxonomic history of the agglutinated (benthonic) foraminiferal genus Cribrostomoides Cushman, 1910 reveals much confusion concerning its type species, coiling mode and apertural characteristics. We believe the originally designated type species of Cribrostomoides Cushman, 1910, C. bradyi Cushman, 1910, to be no more than varietally (i.e. infra-subspecifically) distinct from, and therefore a junior synonym of, Haplophragmoides subglobosus Cushman, 1910. The coiling of Cribrostomoides, as typified by C. subglobosus (Cushman, 1910), is in the form of an involute streptospire characterised by a repeated alternation in axis. The aperture of the genus is equatorially or asymmetrically placed and interio-areal and single (in megalospheric and juvenile microspheric specimens) to areal and multiple (in microspheric adults). In order to stabilise the concept of Cribrostomoides, we have designated lectotypes for both C. bradyi and H. subglobosus, and have also emended the generic diagnosis of Loeblich and Tappan (1987). Criteria for the discrimination of Cribrostomoides emend, herein and allied genera are tabulated.

Approximately 60 species of benthonic foraminifera are recorded from 14 samples collected by the RRS Discovery from water depths of 200–4200 m on the Antarctic Peninsula Shelf and Slope and adjacent areas of the Western Antarctic Ocean. Discussion focuses firstly on benthonic foraminiferal abundance, diversity and assemblage composition and the effects of calcite dissolution and, secondly, on the characteristic assemblages of the study area and their relationships to water-masses.
Lower and Middle Triassic foraminifera from the Eros Limestone, Hydra Island, Greece

Abstract. The systematics and stratigraphic ranges (constrained by conodont dating) of abundant and well preserved foraminiferal faunas from six sections in the Lower and Middle Triassic Eros Limestone of central and western Hydra (Argolis Peninsula, Greece) are described. A joint analysis of the conodonts, foraminifera and bivalves has enabled the Scythian and Anisian stages to be recognized with some certainty within the Eros Limestone carbonate platform. The foraminifera have affinities with those of many other Tethyan localities, in particular the Dinarides, Balkans, Carpathians and the Southern Alps.
Graphic correlation and sequence stratigraphy in the Palaeogene of NW Europe
Authors: Neal J. E. , Stein J. A. , Gamber J. H.
Published: July 2010

Abstract. A sequence stratigraphic analysis of well log, seismic, and biostratigraphic data has documented a pattern of cyclic sedimentation for the Palaeogene of the Central North Sea. Previously published research has also documented cyclic sedimentation related to sea level changes. Integrating Central North Sea subsurface sections with Palaeogene outcrop from NW Europe, using sequence stratigraphic first principles and the graphic correlation method, has produced a chronostratigraphic framework for the Palaeogene of NW Europe.Northwestern Europe basins (London–Hampshire, Paris, and Belgian) have shallow marine to nonmarine environments, revealing basinward and landward fades shifts indicating sea level changes. The problem correlating NW Europe with North Sea deposits has been addressed by correlating a biostratigraphy to the deep water deposits outcropping in Denmark. Once a biostratigraphy joining the subsurface and outcrops is built, key bounding surfaces are correlated between basins. We find that: (1) sedimentation in the deep basin occurs as depositional pulses, separated by time-correlative biostratigraphic data terraces (hiatal intervals), which correspond to persistent seismic reflectors; (2) not all sequence boundaries are resolvable by graphic correlation, but the method brackets packages defined by seismic, log interpretation and biostratigraphy; and (3) correlation with outcrops reveals the true significance of the hiatal intervals.
Notes on the topotype and deep-sea specimens of the planktonic foraminifer Cassigerinelloita amekiensis Stolk
Authors: Li Qianyu , Radford Sally
Published: July 2010

Abstract. Specimens of Cassigerinelloita amekiensis Stolk from the type collections and DSDP/ODP holes are found to possess a microperforate and pustulate wall and a triserial, pseudoplanispiral coiling mode. These characters prompt its affinity with the contemporaneous Guembelitria triseriata (Terquem). An amended description of Cassigerinelloita amekiensis is given, and the peculiar coiling mode discussed.

Pliocene–Pleistocene radiolarian and diatom biostratigraphy of ODP Hole 709C (equatorial Indian Ocean)
Authors: Haslett Simon K. , Kennington Kevin , Funnell Brian M. , Kersley Claire L.
Published: July 2010

Abstract. Ocean Drilling Program (ODP) Hole 709C was drilled on Madingley Rise in the equatorial Indian Ocean. Thirteen radiolarian and diatom events were identified in the Pliocene to Early Pleistocene section studied. Five radiolarian zones could be recognized: Anthocyrtidium angulare, Pterocanium prismatium, Anthocyrtidium jenghisi, Stichocorys peregrina, and Phormostichoartus doliolum zones. The LAD of P. prismatium was found to be an unreliable indicator of the base of the A. angulare zone in Hole 709C and in other upwelling areas. Accordingly, the base of the A. angulare zone is redefined here by the FAD of A. angulare. The Phormostichoartus fistula zone, which normally separates the 5. peregrina and P. doliolum zones, could not be identified due to the scarcity of P. fistula. Standard tropical diatom Pliocene–Pleistocene zones and subzones were identified: Nitzschia reinholdii, Rhizosolenia praebergonii, and Nitzschia jouseae zones. The development of oxygen isotope calibrated dates enabled the dating of some radiolarian events: FAD A. angulare 1.65 Ma, LAD Theocorythium vetulum 2 Ma, LAD A. jenghisi 2.21 Ma, FAD Theocalyptra davisiana 2.33 Ma, FAD Theocorythium trachelium 2.33 Ma, and FAD Lamprocyrtis neoheteroporos 2.4 Ma.
Cytogenetic studies on marine myodocopid Ostracoda: the karyotypes of some species of halocyprids
Authors: Moguilevsky Alicia
Published: July 2010

Abstract. Nineteen species of halocyprid ostracods were dissected and analysed for karyotype studies. Results were obtained for only six species, 5 belonging to Conchoecia and 1 to Halocypris. The uniformity in the chromosome morphology of these species (metacentric/submetacentric) is similar to that found for the cypridinids. The size range of their chromosomes falls within the lower end of the studied cypridinid species. The chromosome counts, in some preparations, were somewhat impaired by uncertain cell boundaries and widely scattered chromosomes. In these cases, the morphology of the identifiable chromosomes and their size ranges were noted and wherever possible a provisional karyotype was suggested.
Southern Australian endemic and semi-endemic foraminifera: a preliminary report
Authors: Li Qianyu , Quilty Patrick G. , Moss Graham , Mcgowran Brian
Published: July 2010

Abstract. The Cenozoic in southern Australia contains many foraminifera endemic to the region in neritic (intermediate- to shallow-water) facies. They were mostly epifaunal and inhabited waters to some 300 m deep. This endemism is first obvious in the later Eocene when Maslinella, Crespinina and Wadella, among others, evolved. More than half of the Eocene endemic species disappeared in the Eocene or Oligocene. There followed in the Oligocene the evolution of such species as Parrellina imperatrix and Astrononion centroplax. The Miocene was a time of slightly reduced endemism and is characterized by migration into the region of many larger (sub)tropical taxa such as Lepidocyclina and Cycloclypeus. The long-ranging genus Notorotalia emerged about 50 Ma ago and is still common in modern southern mid-latitude waters. The youngest common extant species which made their first appearance in the Pliocene–Quaternary include Discorbis dimidiatus and Parredicta porifera, both with a test up to 1.5 mm in diameter. A similar pattern has been recorded in New Zealand.Four phases of endemism can be recognized: later Eocene, Oligocene, Miocene and Pliocene–Quaternary. It appears that the four phases were all stimulated in response to major marine transgressions, respectively the Wilson Bluff ( = Khirthar), Aldingan, Clifton–Longfordian and Hallet Cove–Glanville transgressions. Probably they signal four important stages in the transformation of water masses along the southern continental margin.

Axelheibergella (Ostracoda, Crustacea), a new genus of marginally septate cladocopid ostracods from the central Arctic Ocean
Authors: Briggs William M.
Published: July 2010

Abstract. The genus Axelheibergella is established for cladocopid ostracods with well-developed, radially aligned septa between the outer lamella and the relatively wide, free-margin infold parts of the shell. Two deep-water species of the genus are described from the Holocene of the Alpha Ridge rise and Axel Heiberg slope, central Arctic Ocean (CAO). Two other species are present in the warmer, shallower waters of the Mediterranean region. Presumably the septa are designed to strengthen the free margin of the shell. The relationship of the camerae (interseptal chambers) to marginal pore canals in extant ostracods, including the Punciacopina, and to the marginal shell glands of cladocopids and halocypridid myodocopids is discussed. Cladocopid and podocopid (podocopine) shell ultrastructure is discussed, and new terms are defined. The septate frill and its function in the enigmatic Punciacopina are discussed in the light of recent discoveries of the radically different lifestyle of Manawa, and presumably of Puncia and Promanawa, from other non-punciacean ostracods. It is suggested that the frill of the Punciacopina is homologous to the ala of some cytheracean (cytherurid) podocopid ostracods. Two unnamed species of Puncia from the New Zealand Pleistocene are illustrated, and complement the discussion of septa and camerae in Axelheibergella.
Recent non-marine Ostracoda from Jamaica, West Indies
Authors: Holmes Jonathan A.
Published: July 2010

Abstract. Ostracods were sampled qualitatively at 22 sites from 15 waterbodies in the western part of Jamaica and determinations of the water chemistry and habitat characteristics were made at each locality. Most of the ostracods found belong to the Cypridinae, Cypridopsinae, Cyclocypridinae and Darwinulidae. There is a clear distinction between the faunas found in the larger, permanent lakes and the smaller ponds. The latter are subject to large fluctuations in volume and may desiccate either seasonally or interannually. Within the largest lake, Wallywash Great Pond, there is some degree of spatial zonation in the ostracod faunas that appears to be related to water depth and aquatic macrophyte occurrence. The distribution of modern ostracods within Wallywash Great Pond suggests that the late Quaternary faunal sequence from this lake is primarily a function of lake-level changes.
200 Year interruption of Holocene sapropel formation in the Adriatic Sea
Authors: Rohling E. J. , Jorissen F. J. , De Stigter H. C.
Published: July 2010

Abstract. An interruption of Holocene sapropel S1 is found in cores from various subbasins of the eastern Mediterranean. In core IN68-9 from the Adriatic Sea, sapropel S1 is dated between 8300 and 6340 BP, interrupted between 7100 and 6900 BP (14C years uncorrected for reservoir age). Lithology and variations in the foraminiferal faunas suggest that the interruption is genuine, and not the result of resedimentation. The results indicate that S1 was deposited within a period of enhanced levels of productivity (resulting from increased seasonal contrasts) which started around 9300 BP and ended around 5200 BP. The onset, interruption, and final ending of S1 deposition in the Adriatic Sea, however, appear to have been triggered by changes in ventilation of the basin related to changes in sea surface temperature (SST). Although the rough estimates of SST change are relatively small (< 2°C), they still are significant when compared with the relative SST changes considered necessary to upset convection in the Adriatic. Moreover, recent studies show that the influence of the inferred temperature changes should be viewed in combination with that of reduced salinities due to (1) the deglaciation, and (2) increased humidity in the eastern Mediterranean area during the deposition of S1. The lithological and benthic foraminiferal evidence that sapropel formation in the Adriatic Sea ended around 6340 BP contrasts with the conclusion from a recent geochemical study that sapropel formation in the open eastern Mediterranean would have ended as late as 5000 BP. More significantly, the results of the present study combined with other reports on sapropel interruptions suggest that the process of sapropel formation is not a very stable mode in the basin, but that it may be relatively easily interrupted in response to subtle rearrangements in the balance between productivity and, especially, deep water ventilation.
A re-examination of the Pliensbachian and Toarcian Ostracoda of Zambujal, west-central Portugal
Authors: Boomer Ian , Ainsworth Nigel R. , Exton John
Published: July 2010

Abstract. Pliensbachian and Toarcian Ostracoda first described by Exton (Geological Paper, Carleton University, Ottawa, 79: 1–104 1979) from the Lusitanian Basin, west-central Portugal have been re-examined. As a result, a greater diversity in the Ostracoda (80 species) is now recognized. Two species are newly described (Eucytherura zambujalensis sp. nov., Ektyphocythere mediodepressa sp. nov.) from the marls and calcareous shales of the Maria Pares Hill section near the village of Zambujal. Poor preservation precludes a complete taxonomic review of the present material. Five ostracod zones are proposed; Gammacythere ubiquita–Ogmoconchella gruendeli Zone, Poly cope cerasia–Polycope cincinnata Zone, Liasina lanceolata–Ogmoconcha convexa Zone, Bairdiacypris rectangularis–Kinkelinella sermoisensis Zone, and Cytherella toarcensis-Kinkelinella costata Zone. Although the ostracod assemblages possess strong similarities to those described from Northwest Europe, some of the Zambujal assemblages are dominated by the genus Polycope. A marked faunal turnover, in association with the extinction of the Metacopina occurs in the lower Subzone of the tenuicostatum Zone of Lower Toarcian age. These faunal events are discussed in relation to changing environmental conditions.
