    Description / Table of Contents: Biological studies commenced at the American station Wilkes in Wilkes Land, East Antarctica in 1957. In 1959 station operations were taken over by the Australian National Antarctic Research Expeditions (ANARE) and maintained until 1969 when Casey station was commissioned. This report reviews the information on the fauna obtained by ANARE up to 1980. Studies on invertebrates were limited to ectoparasites of birds and seals. Interest was mostly in the avian and mammalian fauna. Extensive banding of Adélie penguins, southern giant petrels and southern fulmars was undertaken for dispersion and breeding studies. Breeding behaviours of southern fulmars and Antarctic petrels were studied. The main breeding locality of the Weddell seal in the area was located. The southern elephant seal was found to breed at the Windmill Islands, the only known breeding site on the Antarctic continent.

    Description: ABSTRACT The description and application of a modified Scanning Electron Microscope preparation technique using hexamethyldisilazane for small parasitic copepods was demonstrated though a high resolution depiction of individuals of Ergasilus labracis sampled from three spined stickleback ( Gasterosteus aculeatus) in Bay D'Espoir, Newfoundland during summer 2015 and from archival samples retrieved from Atlantic salmon par ( Salmo salar ) stored at the Atlantic reference centre, St. Andrews, New Brunswick. The specimens were very well preserved showing high quality detail of important features and verifying those previously described using light microscopy by Hogans. Additionally the technique allowed excellent in situ demonstrations of mouth parts, swimming legs, and unusual and previously undescribed features of the second antenna including prominent striations and pore-like structures found to define the claw. It is thought that this technique will become a quick and efficient tool for describing important taxonomic features of small parasitic copepods like E. labracis or other similar small aquatic organisms.

    Description: A new model is proposed for analysis of the source clays used to create ceramics, based on geographic, petrographic, mineralogical, mineral-chemistry, and geochemical criteria. The development of this model became feasible after the discovery of a Pliocene volcanic clay horizon on NW Aegina Island, Greece. The volcanic clay contains smectite, mixed-layer chloritesmectite, biotite, and palygorskite and has greater feldspar content than the underlying Pliocene marls, which contain R0 mixed-layer illitesmectite, mica, dolomite, serpentine, talc and gypsum, and, in some places, palygorskite. The two units have distinct geochemical characteristics. In general the Pliocene volcanic clay is richer in SiO 2 , Al 2 O 3 , and Fe 2 O 3 and poorer in Na 2 O, MgO, and P 2 O 5 than the Pliocene marls. The Nb, Zr, Hf, Th, and rare earth element ( REE ) contents are also significantly greater in the Pliocene volcanic clay and comparable to those of the dacitic rocks of the island, reflecting the volcanic origin of the clay. The proposed model was used to identify the source-clay materials that were used for the production of ceramics on the island of Aegina (Aeginetan Ware). All five criteria should be considered in any provenance study. The use of individual criteria on their own can lead to ambiguous conclusions. In the present study the geochemical criterion was particularly helpful. It provided robust evidence for the nature of the source clay. The Pliocene volcanic clay horizon and the underlying Pliocene marls are the candidate raw materials for Aeginetan Ware. Although the Pliocene marls have been invoked as raw materials for Greek Bronze Age (~3000–1100 BC) Aeginetan ceramics and are used as raw materials by modern Aeginetan ceramists, the geochemical characteristics of a large set of Bronze Age Greek Aeginetan sherds with fine and coarse fabrics coincide with those of the Pliocene volcanic clay. This comparative and cumulative evidence suggests that the Pliocene volcanic clay was the main source clay for ancient Aeginetan ceramics, regardless of the fabric (coarse or fine) and that admixture of different sources might not be necessary for fine-grained ceramics.

    Description: Author(s): James M. Murray and Oskar Vafek Majorana quasiparticles localized in vortex cores of a chiral p -wave superconductor hybridize with one another to form bands in a vortex lattice. We begin by solving a fully microscopic theory describing all quasiparticle bands in a chiral p -wave superconductor in a magnetic field, then use this sol… [Phys. Rev.

    Description: Cohesin is an essential structural component of chromosomes that ensures accurate chromosome segregation during mitosis and meiosis. Previous studies have shown that there are cohesin complexes specific to meiosis, required to mediate homologous chromosome pairing, synapsis, recombination, and segregation. Meiosis-specific cohesin complexes consist of two structural maintenance of chromosomes proteins (SMC1α/SMC1β and SMC3), an α-kleisin protein (RAD21, RAD21L, or REC8), and a stromal antigen protein (STAG1, 2, or 3). STAG3 is exclusively expressed during meiosis, and is the predominant STAG protein component of cohesin complexes in primary spermatocytes from mouse, interacting directly with each α-kleisin subunit. REC8 and RAD21L are also meiosis-specific cohesin components. Stag3 mutant spermatocytes arrest in early prophase ("zygotene-like" stage), displaying failed homolog synapsis and persistent DNA damage, as a result of unstable loading of cohesin onto the chromosome axes. Interestingly, Rec8 , Rad21L double mutants resulted in an earlier "leptotene-like" arrest, accompanied by complete absence of STAG3 loading. To assess genetic interactions between STAG3 and α-kleisin subunits RAD21L and REC8, our lab generated Stag3 , Rad21L , and Stag3 , Rec8 double knockout mice, and compared them to the Rec8 , Rad21L double mutant. These double mutants are phenotypically distinct from one another, and more severe than each single knockout mutant with regards to chromosome axis formation, cohesin loading, and sister chromatid cohesion. The Stag3 , Rad21L , and Stag3 , Rec8 double mutants both progress further into prophase I than the Rec8 , Rad21L double mutant. Our genetic analysis demonstrates that cohesins containing STAG3 and REC8 are the main complex required for centromeric cohesion, and RAD21L cohesins are required for normal clustering of pericentromeric heterochromatin. Furthermore, the STAG3/REC8 and STAG3/RAD21L cohesins are the primary cohesins required for axis formation.

    Description: Garnet in Nova Scotia's peraluminous South Mountain Batholith (SMB) displays diversity in its texture and composition that has challenged a comprehensive explanation of its origins. In this study, we have employed oxygen isotope analysis to "fingerprint" magmatic, peritectic, and xenocrystic SMB garnets to take advantage of contrasting {delta}18O of SMB and metasedimentary country-rocks and the slow rates of diffusion of oxygen in garnet. Among texturally well-characterized garnet, values of {delta}18O distinguish magmatic (8.21 {+/-} 0.19{per thousand}; n = 10), metamorphic (9.38 {+/-} 0.13{per thousand}; n = 6), and peritectic garnet (8.67 {+/-} 0.20{per thousand}; n = 6). Values of {delta}18O of magmatic garnet are in equilibrium with coexisting zircon ({delta}18O = 8.14 {+/-} 0.23{per thousand}; n = 21) in the SMB, confirming direct magmatic crystallization of garnet. Entrained metamorphic garnet porphyroblasts preserve high{delta}18O values, confirming a slow rate of intracrystalline diffusion of oxygen in garnet. Averaging of metamorphic and magmatic contributions is evident from the intermediate {delta}18O of peritectic garnet, and corresponds to textural evidence that garnet crystallized dynamically, and that metamorphic wallrocks were partially melted and disaggregated by magmas. In the case of texturally ambiguous garnet found on the margin of the Halifax pluton, {delta}18O varies by 2.5{per thousand} among closely spaced (separated by mm to cm) crystals, signaling heterogeneous populations of magmatic, peritectic, and xenocrystic garnet, and thorough mixing of the host magma. In total, {delta}18O analysis provides a powerful complement to existing methods of determining garnet provenance and a new means to deconvolute garnet assemblages in peraluminous magmas.
