Plasticity in shell morphology and growth among deep-sea protobranch bivalves of the genus Yoldiella (Yoldiidae) from contrasting Southern Ocean regions
Read more of: Plasticity in shell morphology and growth among deep-sea protobranch bivalves of the genus Yoldiella (Yoldiidae) from contrasting Southern Ocean regionsThe ecology of Antarctic deep-sea fauna is poorly understood and few studies have gone beyond assessing biodiversity when comparing deep regions of the Southern Ocean. Protobranch bivalves are ubiquitous in […]

Arctic and Antarctic submarine gullies – a comparison of high latitude continental margins
Read more of: Arctic and Antarctic submarine gullies – a comparison of high latitude continental marginsSubmarine gullies are common features of high latitude continental slopes and, over the last decade, have been shown to play a key role in continental margin evolution, submarine erosion, downslope […]

Management of Antarctic Specially Protected Areas: permitting, visitation and information exchange practices
Read more of: Management of Antarctic Specially Protected Areas: permitting, visitation and information exchange practicesAntarctic Specially Protected Areas (ASPAs) represent the highest level of area protection within the Antarctic Treaty area. To reduce environmental impacts, ASPA visitors must comply with the Area’s management plan […]

Structural limitations in deriving accurate U-series ages from calcitic cold-water corals contrasts with robust coral radiocarbon and Mg/Ca systematics
Read more of: Structural limitations in deriving accurate U-series ages from calcitic cold-water corals contrasts with robust coral radiocarbon and Mg/Ca systematicsRadiocarbon and uranium-thorium dating results are presented from a genus of calcitic Antarctic cold-water octocorals (family Coralliidae), which were collected from the Marie Byrd Seamounts in the Amundsen Sea (Pacific […]

Spatial pattern in Antarctica: what can we learn from Antarctic bacterial isolates?
Read more of: Spatial pattern in Antarctica: what can we learn from Antarctic bacterial isolates?A range of small- to moderate-scale studies of patterns in bacterial biodiversity have been conducted in Antarctica over the last two decades, most suggesting strong correlations between the described bacterial […]

Influence of age, sex and breeding status on mercury accumulation patterns in the wandering albatross Diomedea exulans
Read more of: Influence of age, sex and breeding status on mercury accumulation patterns in the wandering albatross Diomedea exulansAlthough mercury bio-amplifies through the food chain and accumulates in top predators, mercury concentrations in tissues of the wandering albatross are greater than in any other vertebrate, including closely related […]

Lévy flights in random searches
Read more of: Lévy flights in random searchesWe review the general search problem of how to find randomly located objects that can only be detected in the limited vicinity of a forager, and discuss its quantitative description […]

The eastern Palmer Land shear zone: a new terrane accretion model for the Mesozoic development of the Antarctic Peninsula
Read more of: The eastern Palmer Land shear zone: a new terrane accretion model for the Mesozoic development of the Antarctic PeninsulaA major ductile fault zone, the eastern Palmer Land shear zone, has been identified east of the spine of the southern Antarctic Peninsula. This shear zone separates newly identified geological […]
