Antarctic sea ice has been increasing in recent decades, but with strong regional differences in the expression of sea ice change. Declining sea ice in the Bellingshausen Sea since 1979 […]
The distribution of noble gases and helium isotopes in the dense shelf waters of Antarctica reflect the boundary conditions near the ocean surface: air-sea exchange, sea ice formation and subsurface […]
Individuals within populations often differ substantially in habitat use, the ecological consequences of which can be far reaching. Stable isotope analysis provides a convenient and often cost effective means of […]
Defining reliable demographic models is essential to understand the threats of ongoing environmental change. Yet, in the most remote and threatened areas, models are often based on the survey of […]
Understanding species’ responses to environmental change underpins our abilities to make predictions on future biodiversity under any range of scenarios. In spite of the huge biodiversity in most ecosystems, a […]
Antarctic non-native species legislation is contained within the Protocol on Environmental Protection to the Antarctic Treaty, with 2016 marking the 25th anniversary of its adoption. We take this opportunity to […]
We extend the one-dimensional polymer solution theory of bacterial biofilm growth described by Winstanley et al. (2011 Proc. R. Soc. A 467, 1449–1467 (doi:10.1098/rspa.2010.0327)) to deal with the problem of […]
Background Flatfish metamorphosis denotes the extraordinary transformation of a symmetric pelagic larva into an asymmetric benthic juvenile. Metamorphosis in vertebrates is driven by thyroid hormones (THs), but how they orchestrate […]
Surface ozone has been measured since 2004 at the coastal East Antarctic site of Dumont d’Urville (DDU), and since 2007 at the Concordia station located on the high East Antarctic […]
Intrapopulation variation in resource use occurs in many populations of generalist predators with important community and evolutionary implications. One of the hypothesised mechanisms for such widespread variation is ecological opportunity, […]
Robust evidence highlights major shifts in the abundance and distribution of penguins (Adélie, chinstrap, gentoo, emperor, king, and macaroni) breeding on the Antarctic Peninsula and across the Scotia Arc in […]
