Habitat preference, accessibility, and competition limit the global distribution of breeding black-browed albatrosses
Read more of: Habitat preference, accessibility, and competition limit the global distribution of breeding black-browed albatrossesTelemetry methods and remote sensing now make it possible to record the spatial usage of wide-ranging marine animals and the biophysical characteristics of their pelagic habitats. Furthermore, recent statistical advances […]

Proteomics of cryoprotective dehydration in Megaphorura arctica Tullberg 1876 (Onychiuridae: Collembola)
Read more of: Proteomics of cryoprotective dehydration in Megaphorura arctica Tullberg 1876 (Onychiuridae: Collembola)The Arctic springtail, Megaphorura arctica Tullberg 1876 (Onychiuridae: Collembola), is one of the few organisms known to survive the extreme stresses of its environment by using cryoprotective dehydration. We have […]

Great flights by great snipes: long and fast non-stop migration over benign habitats
Read more of: Great flights by great snipes: long and fast non-stop migration over benign habitatsMigratory land birds perform extreme endurance flights when crossing ecological barriers, such as deserts, oceans and ice-caps. When travelling over benign areas, birds are expected to migrate by shorter flight […]

Effects of brooding and broadcasting reproductive modes on the population genetic structure of two Antarctic gastropod molluscs
Read more of: Effects of brooding and broadcasting reproductive modes on the population genetic structure of two Antarctic gastropod molluscsLife-history characteristics exert a profound influence upon the population structure of many marine organisms. However, relatively few genetic studies have compared direct with indirect-developing species in the same ecosystem or […]

Economic value of improved quantification in global sources and sinks of carbon dioxide
Read more of: Economic value of improved quantification in global sources and sinks of carbon dioxideOn average, about 45 per cent of global annual anthropogenic carbon dioxide (CO2) emissions remain in the atmosphere, while the remainder are taken up by carbon reservoirs on land and […]

Potential mode of clutch size determination and follicle development in Eudyptes penguins
Read more of: Potential mode of clutch size determination and follicle development in Eudyptes penguinsIt has long been held that Eudyptes penguins will only ever develop a maximum of two mature yolky follicles to match their invariant two-egg clutch, an idea inferred largely from […]

Either taking it easy or feeling too tired: old Cory’s shearwaters display reduced activity levels while at sea
Read more of: Either taking it easy or feeling too tired: old Cory’s shearwaters display reduced activity levels while at seaIt has long been known that birds change their behaviour, reproductive performance and survival as they mature, including in the first few years after recruitment into the breeding population. However, […]

Conservation biogeography of the Antarctic
Read more of: Conservation biogeography of the AntarcticAim: To present a synthesis of past biogeographic analyses and a new approach based on spatially explicit biodiversity information for the Antarctic region to identify biologically distinct areas in need […]
