At-sea distribution and diet of an endangered top predator: links of white-chinned petrels with commercial longline fisheries
Abstract: Incidental seabird mortality associated with longline commercial fishing is a worldwide ... that at a large scale spatial and temporal overlap occurred and varied among areas and with breeding ... stage. Dynamic analysis (detection for each bird location of any operating vessel within a time/space ... window) revealed few overlap at a small scale. Our study revealed a mismatch between large and small ...

The development of spatially and temporally controlled measures of survival and tag-detection for the CCAMLR tagging program
Abstract: A reliable commercial tagging program is critical to the successful assessment and ... management by CCAMLR of a number of toothfish fisheries in Antarctica. The evaluation of the tagging ... programme relies on two key aspects (i) that the tagged fish have a good chance of survival and (ii) that ... . We propose that, by controlling for the spatial and temporal confounding factors using a case-control ...
