6. Stable isotope analysis reveals trophic variation in adult Antarctic krill (Euphausia superba) around the Antarctic Peninsula from austral fall to early winter

   Abstract:  The Antarctic krill (Euphausia superba) is a key species in the Southern Ocean ... ecosystem and an important link in the food web of the Antarctic ecosystem. The trophic information for this ... species during the transition from the austral fall to the winter is important to understand its poorly ... known overwintering mechanisms.

9. An alternative method for estimating the level of illegal fishing using simulated scaling methods on detected effort

   Abstract:  A new method for estimating illegal fishing effort is put forward. The results from ... this new method are similar to those of the Agnew and Kirkwood (2005) method, and this suggests that ... the current method is adequate under circumstances of low evasion and when good knowledge exists that ... zero observations reflect zero illegal fishing. The new method performs better in the case of zero ...
