2. Population trends of albatrosses and petrels at sub-Antarctic Marion Island

   Abstract:  We report on the population changes of five species of Procellariiform seabirds breeding at Marion Island: wandering albatross (Diomedea exulans), grey-headed albatross (Thalassarche chrysostoma), northern giant petrel (Macronectes halli), southern giant petrel (M. giganteus), and white

4. Longline fishing at Tristan da Cunha: impacts on seabirds

   Abstract:  Tristan da Cunha and Gough Islands in the central South Atlantic Ocean support globally important seabird populations. Two longline fisheries occur within Tristan's Exclusive Economic Zone: a pelagic fishery for tunas and a demersal fishery for bluefish and alfoncino. Fishery

5. Length-at-age juvenile Patagonian toothfish Dissostichus eleginoides

   Abstract:  The fishery for Patagonian toothfish is one of the most valuable in the CCAMLR Area. Age based models are used to assess the status of the stocks of this species. Although age can be estimated using otoliths it has proven difficult for these to be validated. During a recent trawl survey

6. Problems in estimating population length at age from commercial catches, the Patagonian toothfish as an example

   Abstract:  Age based fishery population models require information on size at age of the fished population and the commercial catch. Age-length keys can be produced by standardised random sampling of the commercial catches. This information does not necessarily reflect the size at age of the fished

7. Modelling the impact of fishery by-catches on albatross populations

   Abstract:  1. Several albatross species, including the wandering albatross Diomedea exulans, have shown marked declines in abundance throughout their range. These seabirds are frequently taken as by-catch in longline fisheries and this mortality has been implicated in the population declines. 2. We

8. Global relationships amongst black-browed albatrosses: analysis of population structure using mtDNA and microsatellites

   Abstract:  The population structure of black-browed (Thalassarche melanophris and T. impavida) and grey-headed (T. chrysostoma) albatrosses was examined using both mitochondrial DNA (mtDNA) and microsatellite analyses. mtDNA sequences from 73 black-browed and 50 grey-headed albatrosses were
