As top predators, leopard seals (Hydrurga leptonyx) have a key role in Southern Ocean ecosystems. For example, this species has driven the local collapse of Antarctic fur seals (Arctocephalus gazella) […]
Background: Pelagic seabirds forage over vast areas, and their movements and diet provide valuable insights into environmental conditions that are otherwise difficult to observe. Snow petrels Pagodroma nivea forage largely […]
The surface texture of bird eggshells differs remarkably between species and is thought to play a substantial role in providing physical and microbial protection for the developing embryo. We used […]
The Tibetan Plateau is a high-altitude arid region, where limited in-situ precipitation measurements are available. In this communication, we document a strong precipitation gradient at the southern edge of the […]
Over the Southern Ocean, atmospheric and climate models have large biases in their radiative fluxes, primarily caused by the representation of supercooled liquid and mixed-phase low-level clouds, both at the […]
South Georgia forms one of the most isolated fragments of continental crust on Earth and lies in a remote location in the Southern Ocean. Its geology is dominated by Early […]
This report presents outcomes from the international workshop “Essential Biodiversity Variables (EBV) Framework for Terrestrial Antarctic and Sub-Antarctic Ecosystems,” held in Cambridge, UK, from 18–20 September 2024, with significant online […]
Diversity, distribution and biogeographical aspects of polar macroalgae must be reassessed as they face contemporary environmental changes. Macroalgae are the basis of the marine food web, efficient carbon sinks, biogenic […]
Relativistic electrons are an important space weather hazard, being a major source of radiation damage to satellites and posing a risk to humans in space. We use approximately 20 years […]
Numerical age models are useful tools for investigating the age of the ice in an ice sheet. They can be used to date ice cores or to interpret isochronal horizons […]
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build […]
