Baleen whales are extreme capital breeders, capable of fasting for more than half a year while migrating thousands of kilometres and nursing rapidly growing offspring that quadruple in body size over the same period. To understand this energetic conundrum…
The weaning mass of southern elephant seal pups (Mirounga leonina) is a key predictor of their first-year survival probability. However, variations in pup morphometric characteristics (length, mass and body condition i.e. the residual of the allometric relationship between log(mass) and log(length))…
Amphipods play an important role in Southern Ocean trophic chains. Considering the key role of Pacific Ocean and sea ice ecosystems in the Earth system and the growing impact of global environmental change, it is important to collect information on the status of marine amphipod biodiversity.
Adult specimens, additional juvenile specimens, egg cases and embryos were used to provide a more detailed anatomical description of the Kerguelen sandpaper skate Bathyraja irrasa…
Estimates of the distribution and density of Antarctic krill (Euphausia superba Dana, 1850) were derived from a large-scale survey conducted during the austral summer in the Southwest Atlantic sector of the Southern Ocean and across the Scotia Sea in 2018–19, the '2018–19 Area 48 Survey'.
Marine migratory species tend to be overlooked in marine spatial planning due to limited knowledge of their habitats and migration pathways, resulting in a disconnect between animal migration ecology and spatial management decision making.
A method for combining a proportional-hazards survival time model with a bioassay model where the log-hazard function is modelled as a linear or smoothing spline function of log-concentration combined with a smoothing spline function of time is described.
A method for combining a proportional-hazards survival time model with a bioassay model where the log-hazard function is modelled as a linear function of log-concentration combined with a cubic smoothing spline function of time is described.
Chemical contamination resulting from human activities has been identified in … nearshore marine environments in the vicinity of Antarctic Research Stations. To better … manage and remediate contaminated sites, and to assess the risks of ongoing activities…
Developing water quality guidelines for Antarctic marine environments requires understanding sensitivity of biota to contaminant exposure. Toxicity tests with Antarctic … invertebrates have shown response times to metal exposure takes far longer than the durations of standard bioassay methods.
Within the Pycnogonida, genetic studies have … revealed that Colossendeis megalonyx Hoek (Challenger … Report, Zoology, 3(X), 1–167, 1881), consists of a complex of … several cryptic or overlooked species.
We present the Gattini project: a multisite campaign to measure the optical sky properties above the two high altitude … Antarctic astronomical sites of Dome C and Dome A. The Gattini-DomeC project, part of the IRAIT site testing … campaign and ongoing since January 2006…
Macquarie Island, a small subantarctic island, is home to rockhopper, royal and king penguins, which are often infested with the globally distributed seabird tick, Ixodes uriae. A flavivirus, an orbivirus, a phlebovirus, and a nairovirus were isolated from these ticks and partial sequences obtained.
This report presents the application of the taxonomic guidelines developed by the … Taxonomy Working Group to three pairs of taxa currently listed under Annex 1 … (Attachment 1) of the Agreement on the Conservation of Albatrosses and Petrels … (ACAP): 1. Amsterdam and Wandering Albatross…
Abstract. We examined sexual dimorphism in 11 morphological characters of the Flesh-footed Shearwater (Puffinus … carneipes) and used these characters in a discriminant function analysis (DFA) to enable sexual classification in the field.
Southern elephant seals (Mirounga leonina) are a major consumer of biomass in the … Southern Ocean with a global distribution.
Blood protein analysis including total serum protein and albumin by chemical methods, fibrinogen estimation and serum protein electrophoresis (SPE) was performed on the leopard seal, Hydrurga leptonyx. The most commonly observed SPE pattern was eight fractions designated albumin, a1a, a1b, a2a, a2b…
On the surface, the severity of the Antarctic environment is sufficient to account for the injury rates that might occur there. However, it is argued that injury occurrence is the outcome of multiple factors. A number of such factors…
