Climate-driven changes in disturbance are a major threat to ecosystem Functional diversity. The selective mechanisms underlying ecosystem response to disturbance are far from universal and remain the subject of scientific […]
The strong air temperature warming between the 1950s and 2016 in the Antarctic Peninsula region exceeded the global average warming with evident impacts on terrestrial ecosystems and the two native […]
The Antarctic continent, including its ice shelves, has an area of 13.8 million km2, about half the size of North America and 1.3 times the size of Europe. It is […]
Observations of surface lowering on Larsen C Ice Shelf (LCIS), Antarctica, have prompted concern about its stability. In this study, an ocean model is used to investigate the extent to […]
Antarctic snow represents a microhabitat directly linked with atmospheric precipitation, and through it receives dust, sea spray, organic materials and microbial propagules. Among the microorganisms that inhabit Antarctic snow, fungi […]
The Ellsworth Mountains experience frigid desert conditions. No macroscopic vegetation is present, with only very few published records of microalgae, and the range has received virtually no formal biological survey. […]
Responses to the early (February–July 2020) COVID-19 pandemic varied widely, globally. Reasons for this are multiple but likely relate to the healthcare and financial resources then available, and the degree […]
It is challenging, yet important, to measure the – ever-changing – cold electron density in the plasmasphere. The cold electron density inside and outside of the plasmapause is a key […]
Mechanisms promoting coexistence between closely related species are fundamental for maintaining species diversity. Mechanisms of niche differentiation include allochrony which offsets the peak timing of resource utilisation between species. Many […]
The subglacial hydrological system exerts a critical control on the dynamic behaviour of the overlying ice because its configuration affects the degree of basal lubrication between the ice and the […]
Geomagnetically induced currents (GICs) produced during geomagnetic disturbances pose a risk to the safe operation of electrical power networks. One route to determine the hazard of large and extreme geomagnetic […]
Ice shelves restrict outflow from many of the largest glaciers in Antarctica, thus limiting the Antarctic contribution to sea-level rise. However, past ice-shelf collapse events show they are highly vulnerable […]
