1. Is toothfish catch correlated with the catch of vulnerable benthic invertebrate taxa?

   fishing would be higher than if VMEs are distributed randomly with respect to fishing locations. This ... footprint. If high target fish catch rates are associated with habitats where VMEs are found, impacts from ... evidence that the presence of any of six VME taxa was related to Antarctic toothfish catch at the scale of ... scales (10–100 km) would be useful to determine if both toothfish and individual VME taxa have regionally ...

2. Foraging partitioning between giant petrels Macronectes spp. and its relationship with breeding population changes at Bird Island, South Georgia

   may be reduced by the limited overlap in the activity range, with southern giant petrels foraging ... females in both species. Sex differences agree with previous observations on diet and on attendance at ... seal carcasses, suggesting that females mainly forage at sea, whereas males mainly scavenge on the ... during the breeding season on fur seals, which have increased exponentially in recent years, may be ...

3. Spatial distribution of Champsocephalus gunnari size and age are related with depth

   all species resulted significantly associated with depth, positively in the case of C. gunnari and N ... . rossii and negatively for the remaining species. Less association with depth is observed in C. gunnari as ... the fish grow older, indicating that the spatial separation is controlled by depth. The accumulated ... catches of age I- present maximum difference with the older age classes at about 150 meters a result which ...

5. The reliability of VHF telemetry data for measuring attendance patterns of marine predators: a comparison with Time Depth Recorder data

   the retrieved datasets, 25% of the VHF data could not be interpreted with any reliability ... VHF data collected on 16 lactating Antarctic fur seals to assess onshore attendance, with concurrently ... instrument types, with VHF data overestimating attendance bout duration by approximately 8.9h on average ... , suggesting that VHF data is an inappropriate method for collecting attendance data. Modelling the raw VHF ...
