Exploring the use of transformation group priors and the method of maximum relative entropy for Bayesian glaciological inversions

1 October, 2015 by Robert Arthern

Ice-sheet models can be used to forecast ice losses from Antarctica and Greenland, but to fully quantify the risks associated with sea-level rise, probabilistic forecasts are needed. These require estimates…

23 September, 2015 by Kevin Newsham

The ever increasing microbial resistome means there is an urgent need for new antibiotics. Metagenomics is an underexploited tool in the field of drug discovery. In this study we aimed…

Chemical fingerprints encode mother-offspring similarity, colony membership, relatedness and genetic quality in fur seals

8 September, 2015 by Jaume Forcada

Chemical communication underpins virtually all aspects of vertebrate social life, yet remains poorly understood because of its highly complex mechanistic basis. We therefore used chemical fingerprinting of skin swabs and…

Crystallisation temperatures of the most Mg-rich magmas of the Karoo LIP on the basis of Al-in-olivine thermometer

1 September, 2015 by Teal Riley

Calculating reliable temperatures of Mg-rich magmas is problematic because melt composition and KD(Fe-Mg)ol-liq, the key parameters of many traditional thermometers, are difficult to constrain precisely. The recently developed Al-in-olivine thermometer…

Key metabolic pathways involved in xenobiotic biotransformation and stress responses revealed by transcriptomics of the mangrove oyster Crassostrea brasiliana

1 September, 2015 by Michael Thorne, Melody Clark

The Brazilian oyster Crassostrea brasiliana was challenged to three common environmental contaminants: phenanthrene, diesel fuel water-accommodated fraction (WAF) and domestic sewage. Total RNA was extracted from the gill and digestive…

Limited genetic differentiation among chinstrap penguin (Pygoscelis antarctica) colonies in the Scotia Arc and Western Antarctic Peninsula

1 September, 2015 by Michael Dunn

Long-term monitoring of seabird numbers around Antarctica has revealed that the chinstrap penguin (Pygoscelis antarctica) is largely declining throughout its range in the Scotia Arc. Whether archipelagos across this large…

Comparative analysis of Deschampsia antarctica Desv. population adaptability in the natural environment of Admiralty Bay (King George Island, maritime Antarctic)

1 September, 2015 by Peter Convey

Plants inhabiting extreme environments may possess features allowing them to tolerate sudden abrupt changes in their environment, a phenomenon often known as ‘adaptability.’ However, ability or success in developing adaptability…

Mercury accumulation in gentoo penguins Pygoscelis papua: spatial, temporal and sexual intraspecific variations

1 September, 2015 by Norman Ratcliffe, Philip Trathan

Mercury emissions have increased over the past decades affecting even remote areas such as Antarctica. As gentoo penguins (Pygoscelis papua) breed on many of the islands surrounding Antarctica, foraging close…

Evolutionary factors affecting the cross-species utility of newly developed microsatellite markers in seabirds

1 September, 2015 by Richard Phillips

Microsatellite loci are ideal for testing hypotheses relating to genetic segregation at fine spatio-temporal scales. They are also conserved among closely related species, making them potentially useful for clarifying interspecific…

An examination of the relationship between the Southern Annular Mode and Antarctic surface air temperatures in the CMIP5 historical runs

1 September, 2015 by Gareth Marshall, Thomas Bracegirdle

Strong relationships exist between the Southern Annular Mode (SAM) and surface air temperature (SAT) across much of Antarctica. Changes in the SAM will have a profound influence on future Antarctic…

Airborne radar evidence for tributary flow switching in Institute Ice Stream, West Antarctica: implications for ice sheet configuration and dynamics

1 September, 2015 by Hugh Corr

Despite the importance of ice streaming to the evaluation of West Antarctic Ice Sheet (WAIS) stability we know little about mid- to long-term dynamic changes within the Institute Ice Stream…

Assessing the design and power of capture-recapture studies to estimate demographic parameters for the Endangered Oceania humpback whale population

1 September, 2015 by Jennifer Jackson

Capture-recapture studies offer a powerful tool to assess abundance, survival and population rate of change (λ). A previous capture-recapture study, based on DNA profiles, estimated that the IUCN-listed Endangered Oceania…

The ‘scaly-foot gastropod’: a new genus and species of hydrothermal vent-endemic gastropod (Neomphalina: Peltospiridae) from the Indian Ocean

1 August, 2015 by Katrin Linse

The ‘scaly-foot gastropod’ is widely recognized as an iconic species of deep-sea hydrothermal vent ecosystems in the Indian Ocean. Uniquely among gastropods, this species carries hundreds of dermal sclerites on…

Iron budgets for three distinct biogeochemical sites around the Kerguelen archipelago (Southern Ocean) during the natural fertilisation experiment KEOPS-2

29 July, 2015 by Jean-Baptiste Sallee

Iron availability in the Southern Ocean controls phytoplankton growth, community composition and the uptake of atmospheric CO2 by the biological pump. The KEOPS-2 experiment took place around the Kerguelen plateau…

A diatom-conductivity transfer function for reconstructing past changes in the Southern Hemisphere westerly winds over the Southern Ocean

16 July, 2015 by Dominic Hodgson

Sub-Antarctic islands are ideally placed to reconstruct past changes in Southern Hemisphere westerly wind behaviour. They lie within their core belt (50–60°S) and the strong winds deliver sea salt ions…

Against the flow: evidence of multiple recent invasions of warmer continental shelf waters by a Southern Ocean brittle star

22 June, 2015 by Chester Sands, David Barnes

The Southern Ocean is anomalously rich in benthos. This biodiversity is native, mostly endemic and perceived to be uniquely threatened from climate- and anthropogenically- mediated invasions. Major international scientific effort…
