1. Among-year variation in growth of Antarctic krill Euphausia superba based on length-frequency data

   Abstract:  Understanding the temporal variability in vital rates (e.g. growth and survivorship) of wild populations is practically and statistically difficult but crucial for connecting such variation to mechanistic drivers and their population consequences. For somatic growth, empirical estimates

2. Evaluation of populations of chinstrap and gentoo penguins at Cierva Cove (ASPA N° 132). Is this site an appropriate control area for non-fishing effects?

   Abstract:  We present new censuses data for a suite of chinstrap (Pygoscelis antarctica) and gentoo (P. papua) penguin colonies in the Cierva Cove region of the Danco Coast, including ASPA No. 134. Data indicate an overall increase in breeding population size of chinstrap and gentoo penguins. Given

3. A critical re-examination of the evidence for a possible dependence of Weddell seals (Leptonychotes weddellii) on Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea, Antarctica

   Abstract:  There is presently debate over the degree to which the fishery for Antarctic toothfish (Dissostichus mawsoni; ‘toothfish’) in the Ross Sea may affect the ecological viability of top predators such as Weddell seals (Leptonychotes weddellii), but available evidence remains inconclusive as

4. To what extent do type C killer whales (Orcinus orca) feed on Antarctic toothfish (Dissostichus mawsoni) in the Ross Sea, Antarctica?

   Abstract:  Information on type C killer whales in the Ross Sea region is reviewed, in particular on the trophic overlap between type C killer whales and Antarctic toothfish. Killer whale population ecology (high consumption rates, low abundances, low production rates, often specialised diets,

5. Abundance and trends in the breeding population of Adélie penguins (Pygoscelis adeliae) in the western Ross Sea

   Abstract:  The Adélie penguin (Pygoscelis adeliae) is an indicator species used by the CCAMLR Ecosystem Monitoring Program (CEMP) to detect effects of anthropogenic activities (e.g. commercial fishing) on the Antarctic marine ecosystem.  The goal of this study was to assess annual variation and

6. Competition-mediated prey availability drives Adélie penguin (Pygocelis adeliae) chick size, mass and condition at colonies of differing size in the southern Ross Sea

   Abstract:  Understanding the relative effects of biotic and abiotic drivers of survival, and the interactions between them, is a key component in understanding the factors driving changes in animal populations.  Body size, mass and condition may be important determinants of an organism’s ability to

7. The dynamic of krill fishery and the environment in the Antarctic Peninsula Subarea (48.1)

   Abstract:  The dynamic of krill fishery in the Subarea 48.1 and its relation to the environment variability was analyzed.  It was revealed  that the dynamic of ААО indices (Antarctic Oscillation Index) used as an indicator of the inter-annual and long-period fluctuations of hydrometeorological

8. Information for the management plan for CEMP sites within the Argentine Islands

   Abstract:  INFORMATION FOR THE MANAGEMENT PLAN FOR CEMP SITES WITHIN THE ARGENTINE ISLANDS presented in accordance with Conservation Measure 91-01 (2004) “Procedure for according protection to CEMP sites”, ANNEX 91-01/A “INFORMATION TO BE INCLUDED IN MANAGEMENT PLANS FOR CEMP SITES”.

9. A method to evaluate selection of Antarctic krill in towed fishing gears

   Abstract:  The pelagic trawlers involved in the fishery for Antarctic krill (Euphausia superba) apply different trawl designs. Very little information exists on the size selectivity of E. superba. Size selectivity describes a given trawls designs ability to catch different sizes of a population and

10. Observations of penguins in the waters off South Orkney Islands, 2011–2013

    Abstract:  In this study, we introduce the initial results from three seasons (2011-2013) of penguin observations made in the waters off the South Orkney Islands. The surveys followed pre-determined transect lines during five consecutive days within late January and early February. Three species of
