Status of white-chinned petrels Procellaria aequinoctialis Linnaeus 1758, at Bird Island, South Georgia
population status. We assessed the status of white-chinned petrels at Bird Island, South Georgia by comparing ... the distributioin and density of occupied burrows in 1981 and 1998. In both surveys white-chinned ... petrel burrows occurred in one-quarter of the 460–47736-m2 quadrats surveyed. The total number of burrows ... in each quadrat was consistent between each survey but we estimate an overall decrease of 28% in ...

Abstract: We compare two versions of the krill-predator-fishery model to demonstrate the extent ... to which the predictions of KPFM1 can be reproduced with KPFM2. We also discuss the incorporation of ... seasonality into parameter estimates and a necessary change in the predator recruitment function of KPFM2 ... logic of KPFM2 have not caused substantial changes in model results. In essence, KPFM1 has become a ...
