Reduced bait loss and bycatch of seabirds in longlining by using a seabird scarer
Abstract: Although longlining is regarded as a highly conservation oriented method of fishing ... , bycatch of seabirds on longlines is a problem in certain seasons and areas. Birds feeding on the bait ... during setting of the gear might cause considerable bait loss and occasional hooking of birds might ... eventually give high mortalities considering the large amounts of hooks used. Both from a fishery and bird ...

On the estimation of some demographic parameters for Adelie penguins
Abstract: A population dynamics model for Adelie penguins is developed which takes account of the ... factors of lower adult survival rates in the year of first breeding, and the possibility that such ... breeding may be deferred one year if conditions are poor. A Bayesian approach for estimation of the model ... for illustrative purposes. The results for this case would likely be improved by the provision of more ...
