1. Further progress on modelling the krill–predator dynamics of the Antarctic ecosystem

   Abstract:  This paper addresses work conducted on the Mori-Butterworth multi-species model of the ... Antarctic ecosystem subsequent to the Ulsan meeting of the IWC Scientific Committee. Points raised about the ... unable to fully utilise the primary production available. The precision of parameters estimated when ... fitting the model to abundance and trend data is reported. The model is extended to include an “other ...

2. The diet of the Antarctic fur seal Arctocephalus gazella at Harmony Point, South Shetland Islands: evidence of opportunistic foraging on penguins?

   Abstract:  The diet of non-breeding male Antarctic fur seals Arctocephalus gazella was ... investigated at Harmony Point, Nelson Island, South Shetland Islands, by the analysis of 523 scats collected ... from January to March 2001 and 2002. The composition of the diet was diverse and both, pelagic and ... benthic-demersal preys were represented in the samples. Overall, the Antarctic Krill Euphausia superba and ...

3. Problems and prospects for the Convention on the Conservation of Antarctic Marine Living Resources twenty years on

   Abstract:  Twenty years after its adoption, the Convention on the Conservation of Antarctic Marine ... considering the impact of existing or proposed fisheries on the entire ecosystem, rather than on just the ... harvested species. However, the recent picture of fisheries activities within the Convention area suggests a ... substantial – and perhaps widening- gap between theory and practice.

4. Assessment models for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea for the years 1997–98 to 2010–11

   Abstract:  We provide an update of the Bayesian sex and age structured population stock assessment ... model for Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea region (Subareas 88.1 and SSRUs ... 88.2A–B), using revised catch, catch-at-age, and tag-recapture data for the 2010–2011 seasons. The 2011 ... reference model using the selected trips tag data gave a similar, but slightly higher estimate of initial ...

5. A PRELIMINARY BALANCED TROPHIC MODEL OF THE ECOSYSTEM OF THE ROSS SEA, ANTARCTICA, WITH EMPHASIS ON APEX PREDATORS

   Abstract:  We report on the development of a mass balanced carbon-budget trophic model of the Ross ... Sea as a step towards investigating ecosystem effects of the fishery for Antarctic toothfish ... (Dissostichus mawsoni). The model has 30 trophic groups representing all the major biota of the Ross Sea. Many ... of the lower trophic level species in the model are grouped by functional role because information is ...

6. BIOMASS ESTIMATES AND SIZE DISTRIBUTIONS OF DEMERSAL FINFISH ON THE ROSS SEA SHELF AND SLOPE FROM THE NEW ZEALAND IPY-CAML SURVEY, FEBRUARY-MARCH 2008

   Abstract:  during February and March 2008 as part of the International Polar Year. The main aim of ... the survey was to carry out a Census of Antarctic Marine Life in this regionfocussing on sampling the ... pelagic and benthic habitats on the shelf, slope, abyss, and seamounts in the Ross Sea region (CCAMLR ...

7. The foraging range of Adelie penguins at Bechervaise Island, Mac. Robertson Land, Antarctica, and its overlap with the krill fishery

   Abstract:  The foraging ranges of six female and four male Adélie penguins breeding at Bechervaise ... Island near Mawson Station (Mac. Robertson Land) were determined by satellite tracking, using the ARGOS ... system. Birds were tracked over four foraging trips (by 2 females and 4 males) during the incubation ... birds were feeding chicks. Most birds made foraging trips to the continental shelf break (1000m isobath ...
