BioTIME: A database of biodiversity time series for the Anthropocene

Maria Dornelas, +286 more
TL;DR: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time to enable users to calculate temporal trends in biodiversity within and amongst assemblage using a broad range of metrics.
Journal ArticleDOI

The diet of Antarctic fur seals Arctocephalus gazella (Peters) during the breeding season at Heard Island

TL;DR: Trial fishing around Heard Island indicates that one of the major dietary items of the seals (C. gunnari) is of probable commercial importance and therefore any plans for the establishment of a fishery on Heard Island grounds must be considered in this light.
Journal ArticleDOI

The diet of Antarctic fur seals during the late autumn and early winter around Heard Island

TL;DR: The diet of Antarctic fur seals around Heard Island was investigated in May and June 1990, and fish predominated in samples, occurring in an average of 93.4% of droppings.
Journal ArticleDOI

Population structure of the Patagonian toothfish around Heard, McDonald and Macquarie Islands

TL;DR: The genetic heterogeneity between the three locations indicates restricted gene flow, with the fish at each location comprising independent units, anddepletion in one location is therefore unlikely to be quickly replaced by immigration from another.
Journal ArticleDOI

Diet composition of Emperor Penguin chicks Aptenodytes forsten‘ at two Mawson Coast colonies, Antarctica

TL;DR: The diet composition of Emperor Penguin Aptenodytes forsteri chicks was examined at Auster and Taylor Glacier colonies, near Australia's Mawson station, Antarctica, between hatching in mid-winter and fledging in mid/summer by “water-offloading” adults.
