Résumé: Dense coral-sponge communities on the upper continental slope off George V Land have been identified as a Vulnerable Marine Ecosystem in the Antarctic. The challenge is now to understand their likely distribution. The CEAMARC survey of 2007/2008 found these communities at sites on the upper slope in depths of 570 – 950 m. Based on these results we propose some working hypotheses to explain Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	5.3

Résumé: Analysis of VME data collected in 2008/09 by UK vessels and national and international observers onboard was carried out to explore evidence of VMEs in the Ross Sea. 2008/09 data corroborated areas in 88.1I, E and F identified in our previous analysis of data collected by observers on UK vessels between 2005 and 2007 on benthic taxa recovered from longlines. A new area was identified within 88 Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	5

Résumé: This paper reviews, reanalyzes and contributes new data pertinent to understanding genetic connectivity in benthic invertebrates at differing spatial scales in Antarctica. This information is valuable for understanding the potential resilience of benthic communities under threat from bottom fishing. Genetic connectivity allows insight into the realized dispersal of organisms, i.e. the Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	3.3
WS-VME-09/07 Plus d'infos	IS THE BYCATCH OF VULNERABLE INVERTEBRATE TAXA ASSOCIATED WITH HIGH CATCH RATES OF FISH IN THE ROSS SEA LONGLINE FISHERIES? Parker, S.J., Mormede, S. Résumé: Protecting vulnerable marine ecosystems (VMEs) from significant adverse impacts caused by fishing activities requires knowledge of the distribution of those communities relative to the fishing footprint. If high fish catch rates are associated with habitats where VMEs are found, impacts from fishing are more likely to occur than if VMEs are distributed randomly with respect to fishing Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	5.1
WS-VME-09/08 Plus d'infos	IDENTIFYING TAXONOMIC GROUPS AS VULNERABLE TO BOTTOM LONGLINE FISHING GEAR IN THE ROSS SEA REGION Bowden, D.A., Parker, S.J. Résumé: Implementing measures to avoid significant adverse impacts to vulnerable marine ecosystems (VMEs) requires a specific list of the taxa that are considered vulnerable. New Zealand identified an interim list of taxa to monitor in fishery bycatch in the Ross Sea as part of its 2008 benthic fisheries impact assessment. The rationale for including or excluding each taxonomic group is described Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	3.2
WS-VME-09/09 Plus d'infos	DETECTION OF COLD SEEPS AND HYDROTHERMAL VENTS Logan, G., O’Brien, P.E., Rollet, N., Kennard, J., Jones, A. Résumé: Cold seeps and hydrothermal vents can be detected by a number of oceanographic and geophysical techniques as well as the recovery of characteristic organisms. While the definitive identification of a seep or vent and its accompanying fauna is seldom unequivocal without significant effort. We suggest an approach to identifying associated VMEs in the CCAMLR region that uses the results of Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	5.1

Résumé: Publicly available bathymetry and geophysical data can be used to map geomorphic features of the Antarctic continental margin and adjoining ocean basins at scales of 1:1-5 million. These data can also be used to map likely locations for some Vulnerable Marine Ecosystems. Seamounts over a certain size are readily identified and submarine canyons and mid ocean ridge central valleys which harbour Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	5.3

Résumé: A global database of life-history characteristics, including growth rate, age, maximum size and reproductive parameters, was established for benthic, habitat-forming taxa and associated physical and chemical variables, including depth, temperature, oxygen concentration, salinity and nutrients. The metadata fields are described. At present more than 850 records representing more than 650 taxa Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	3.1

Résumé: Following on from earlier analyses presented to WG-EMM, meta-analyses of life-history characteristics and their relationships with physical and chemical variables were undertaken for habitat-forming invertebrates other than cnidarians. Particular focus was placed on bryozoans and sponges which are known to form important biogenic habitat in the Southern Ocean. Data were extracted from a global Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion	3.1

Résumé: Prediction of species ’distributions is central to diverse applications in ecology, evolution and conservation science. There is increasing electronic access to vast sets of occurrence records in museums and herbaria, yet little effective guidance on how best to use this information in the context of numerous approaches for modelling distributions. To meet this need, we compared 16 modelling Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Approuvé par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion

Résumé: Current circumstances — that the majority of species distribution records exist as presence-only data (e.g. from museums and herbaria), and that there is an established need for predictions of species distributions — mean that scientists and conservation managers seek to develop robust methods for using these data. Such methods must, in particular, accommodate the difficulties caused by lack Read More Soumis par: Admin Admin (Secrétariat de la CCAMLR) Demander un document de réunion
