Accurate estimates of vegetation cover underpin ecological monitoring and conservation, yet lichens, the dominant primary producers across the coldest biomes remain poorly represented. Recent satellite-derived products provide Antarctic-wide estimates of […]
Species distribution models using animal tracking data to predict foraging habitat suitability can inform dynamic ocean management techniques that respond to changing environmental conditions. Such models require accurate transferability in […]
The stability of the West Antarctic Ice Sheet (WAIS) remains a major uncertainty in sea-level projections, and geologic records provide important constraints on its past behavior. We present 40Ar/39Ar ages […]
Antarctica’s remote wilderness is increasingly impacted by human activities such as tourism, scientific research, and historical and contemporary exploitation of marine resources. Despite regulatory measures, these activities continue introducing pollutants, […]
Abstract Background With over 10,000 recognized species, birds constitute one of the most diverse and widely distributed vertebrate groups. Although avian genomics has advanced rapidly over the past decade, substantial […]
Ecosystem engineering is an important factor influencing species establishment in novel environments. Here we tested how shell middens created by kelp gulls (Larus dominicanus) affect the growth of candidate non-native […]
During the 94/95 field season seismic measurements of the ice- and water-column thickness were made at 15 km (average) intervals along a 2300 km traverse. This zig-zag traverse covered the […]
This review considers the current status, and highlights existing knowledge gaps, on Antarctic terrestrial and freshwater biological responses to climate change. Climate change is considered to be one of the […]
Around Antarctica, disturbance from iceberg scouring and natural macroalgal senescence result in the accumulation of macroalgal detrital material. This detritus in turn supports a significant abundance of detritivorous invertebrates and […]
Introduction: Migratory marine species face complex conservation challenges due to their dependence on habitats spanning vast scales. Humpback whales in the Western South Atlantic illustrate this complexity, undertaking long-distance migrations […]
The total amount of methane (CH4) released from the global ocean is uncertain. It is important that this component of the global CH4 budget is better constrained, as a more […]
In the Southern Ocean, reconstructions of past sea ice conditions remain challenging because of limited proxy and calibration approaches. Sedimentary DNA can complement the available proxies for reconstructing past sea […]
