1. Developing conceptual models of elements of the Antarctic marine ecosystem: Antarctic krill (Euphausia superba)

   Abstract:  A simple generalised conceptual life history model for Antarctic krill is developed based on observations and data from the literature. The model attempts to take into account the observed relationships between Antarctic krill and its biotic and abiotic environment. Krill life history is

2. A conceptual model of the krill fishery

   Abstract:  The behaviour patterns of Japanese krill fishery vessels in Area 48 were analysed using questionnaires on the reasons why the vessel changed their fishing grounds, which were sent out to of the Japanese fishing vessel since the 1989/90 fishing season. Among many reasons for changing

3. Analysis of trends in Japanese krill fishery, and its implication

   Abstract:  Haul by haul logbook data from the Japanese krill fishery from 1980/81 to 2003/04 fishing season was analysed. By using statistical modeling (linear mixed model) a series of predicted intra- and inter-annual trends of standardized fishery indices are presented. The results strongly

4. Developing conceptual models of elements of the Antarctic marine ecosystem: Adélie penguins

   Abstract:  In this paper we present a simple generalised conceptual life history model of Adélie penguins based primarily on data collected from Béchervaise Island, East Antarctica. The model uses life history categories based on an individual penguins reproductive potential in any given year,

5. Modelling availability bias using existing time series count data: Adélie penguins as a case study

   Abstract:  It is widely acknowledged that counts of Adélie and other penguin species at breeding sites in Antarctica during the breeding season are influenced by the date at which they are undertaken. A count of some attribute of the population on any date may therefore need to be adjusted by some

6. Assessing the accuracy of penguin breeding abundance estimates at regional scales in Antarctica from existing count data: a review using Adélie penguins as a case study

   Abstract:  There is a large body of existing count data in the literature for penguins at their breeding sites in Antarctica and the sub-Antarctic islands. These data have been summarised into several compilation documents and their accuracy assessed therein on a site-by-site basis. There has been

7. Developing and applying a general abundance estimator for land-based predator surveys: Adélie penguins as a case study

   Abstract:  The development of a general estimator of abundance would facilitate a standardised approach to regional and circum-Antarctic surveys of land-based predators. Such a generalised estimator is outlined, and its applicability illustrated by adapting it to the specific problem of estimating

8. Changes in the foraging range of Adélie penguins as the breeding season progresses

   Abstract:  1. This paper describes temporal changes in foraging range throughout the breeding season of Adélie penguins nesting at Béchervaise Island on the Mawson coast of Eastern Antarctica. A decade’s worth of satellite tracking data was loaded into geographical information systems (GIS)

9. Developing conceptual models of the Antarctic marine ecosystem: squid

   Abstract:  The Convention for the Conservation of Antarctic Marine Living Resources (CCAMLR) is currently considering plausible models of the Southern Ocean ecosystem within the Working Group on Ecosystem Monitoring and Management (WG-EMM). While recognised to be an important component of this

10. Biotopic and spatial distribution of krill Euphausia superba Dana (Crustacea, Euphausiacea) length groupings in the Atlantic sector of Antarctic in summer 1984 and 1988

    Abstract:  Three basic length groupings of krill were identified with the clustering analysis on the basis of the data of two complex surveys carried out in the western Atlantic sector of Antarctic in summer 1984 and 1988. The large-length grouping is biotopically associated with the waters of the
