Characterising the preferred at-sea habitats used by chinstrap penguins and the fishery for Antarctic krill: slow-flowing, nearshore waters over shallow bathymetry
Abstract: We show that the preferred habitat models developed by Warwick-Evans et al. (2017) for ... chinstrap penguins breeding at the South Orkney Islands, can be modified to predict the at-sea distribution ... of chinstraps breeding at the South Shetland Islands, based on the distance from the colony, and the ... bearing to the shelf edge, adjusting for the at-sea density of Pygoscelis penguins from other colonies ...

Entanglement of Antarctic fur seal Arctocephalus gazella in man-made debris at Bird Island, South Georgia during the 2001 winter and the 2002 breeding season
Abstract: Results of the survey of entanglements of Antarctic fur seals at Bird Island, South ... Georgia for the twelfth consecutive winter (2001) and fourteenth consecutive summer (2001/02) are reported ... here. The overall number of entanglements showed an increase from recent years, with 20 entanglements ... reported over winter and 48 during the summer breeding period.
