Global fungal diversity is estimated to range in the millions, yet it remains severely underexplored, especially in extreme environments. Fewer than 5% of species have been officially identified and characterised. Estimates suggest that 70%–90% of soil fungi remain uncultivable…
Gravity waves provide a key mechanism for the vertical transport of energy and momentum from the active near-surface weather to the upper reaches of the neutral and ionised atmosphere. Generation mechanisms vary between storms, fronts…
Population monitoring provides information on species conservation status. We reassess the status of the southern elephant seal population at Macquarie Island. The number of cows on the isthmus, ~20% of the total population, correlated with counts for the whole island (i.e.
Genetic diversity is fundamental to biological diversity, vital for species’ health and adaptation to environmental change. Under the recently adopted Kunming-Montreal Global Biodiversity Framework (GBF)…
Publication: 2019. Final Report, FRDC Project 2017/021. Australian Antarctic Division and the Fisheries Research and Development Corporation. Kingston, Australia. ISBN 978-1-876934-33-0. For this study, Antarctic toothfish samples were collected from CCAMLR Subareas 48.2, 48.4, 48.6, 88.1, 88.
Elasmobranchs (sharks, skates and rays) are among the least productive fish species, which make their populations vulnerable to increased mortality. Although skates exhibit elevated vulnerability to fishing, they are commonly caught as incidental bycatch in demersal fisheries.
The SCAR Krill Action Group (SKAG) provides a conduit for science to feed into the management of the Antarctic krill fishery, as well a more general forum to promote collaboration, help early career researchers, improve understanding of krill biology and ecology, and facilitate information exchange.
The Australian Antarctic Strategy and 20 Year Action Plan: Update 2022 reaffirms Australia's ongoing commitment to best practice environmental stewardship in Antarctica. Related high priority actions over the next five years include establishing a Cleaner Antarctica science program…
Shallow-water benthic communities throughout coastal Antarctica share many species and are governed by similar physico-oceanographic processes.
During the summer of 2008/09, measurements were taken at 34 magnetotelluric (MT) stations along profiles totaling approximately 180 line km in the Prydz Bay region of Antarctica. Prydz Bay comprises several regions of coastal outcrops with distinct geological histories…
Many parasitic Apicomplexa, such as Plasmodium falciparum, contain an unpigmented chloroplast remnant termed the … apicoplast, which is a target for malaria treatment. However, no close relative of apicomplexans with a functional … photosynthetic plastid has yet been described.
Fan-Beam and Pencil-Beam Radar Scaterrometers on many satellites in polar orbits, e.g. ERS-1/2, ADEOS-1/2 and QuikSCAT, have been designed primarily for estimation of vector winds over the … global oceans. However, these scatterometers…
We carried out a phylogeographic study using mtDNA (COII) for the endemic springtail … Desoria klovstadi … (formerly … Isotoma klovstadi … ) from northern Victoria Land, Antarctica. Low … levels of sequence divergence ( ¡Ü … 1.6%) across 26 unique haplotypes (from 69 individuals)…
The Australian Antarctic Data Centre (AADC) plays a key role in managing and providing … access to scientific data collected under the auspices of the Australian Antarctic program. Through its membership of the Joint Committee of Antarctic Data Management (JCADM)…
This study examines the molecular-genetic divergence and evolution of Australian aquatic micro-Crustacea Daphnia … and Daphniopsis. The results indicate that species of Daphniopsis are accommodated within the genus Daphnia. Although their phyletic integrity is no longer supported…
The invertebrate animals that inhabit ice-free areas of East Antarctica have been studied … since the earliest days of Antarctic science. However, even though biodiversity and … biogeography is reasonably well known for some regions (e.g. Southern Victoria Land)…
Thorium-234 is increasingly used as a tracer of ocean particle flux, primarily as a means to estimate particulate organic carbon … export from the surface ocean. This requires determination of both the 234Th activity distribution (in order to calculate 234Th fluxes)…
The Australian Antarctic Division is responsible for management of 42% of the Antarctic continent, equivalent to 3/4 the size of Australia. Management of such a large and remote area creates many practical difficulties…
On sub-Antarctic Macquarie Island, we examined pup weaning mass of southern elephant seals in relation to human presence. Pup weaning mass was previously found to be positively associated with 1st-year survivorship. Weaned pups were weighed in a remote area, Middle Beach…
In-situ zircon U–Pb and Hf isotopic analysis … via laser ablation microprobe-inductively coupled plasma … mass spectrometer (LAM-ICPMS) of samples from … Kemp and MacRobertson Lands…
Graphical methods for the exploration of ecological databases … Ben Raymond, Lee Belbin, Jonathan Stark … Scientific data repositories are becoming increasingly characterised by large data sets stored in web-accessible, structured databases.
