1. Using the EPOC modelling framework to assess management procedures for Antarctic krill in Statistical Area 48: evaluating spatial differences in productivity of Antarctic krill

   Abstract:  Spatially explicit simulation models of the Antarctic marine ecosystem are needed to ... development of a harvest strategy are whether (i) spatial differences in the productivity of krill give rise ... to differential affects on predators in different locations, (ii) movement of krill between locations ... conservation objectives for predators could be affected by those changes. Productivity of krill can be impacted ...

4. Antarctic icefishes (Channichthyidae) – a unique family of fishes – a review

   Abstract:  Icefish are a family of species unique among vertebrates in that they possess no ... haemoglobin. With the exception of one species, icefish live only in the cold – stable and oxygen – rich ... environment of the Southern Ocean.
