“…Similar to royal albatrosses, White-capped and Black-browed albatrosses are also distributed over shelf areas and the shelf-break (but the latter also in coastal and oceanic waters) (Phillips et al 2005;Jiménez et al 2010Jiménez et al , 2015Copello et al 2013). A plausible explanation is that individual royal albatrosses spend a higher proportion of the time in frontal zones in these areas where there is more floating plastic, or following vessels (picking up the rubbish thrown overboard) than mollymawks.…”

Plastics and other marine debris affect wildlife through entanglement and by ingestion. We assessed the ingestion of marine debris by seven albatross species in the southwest Atlantic by analysing stomach contents of birds killed in fisheries. Of the 128 specimens examined, including four Diomedea species (n=78) and three Thalassarche species (n=50), 21 (16.4%) contained 1-4 debris items, mainly in the ventriculus. The most common type was plastic fragments. Debris was most frequent in Diomedea species (25.6%) and, particularly, D. sanfordi (38.9%) and very rare in Thalassarche species (2.0%), presumably reflecting differences in foraging behavior or distribution. Frequency of occurrence was significantly higher in male than female Diomedea albatrosses (39.3% vs. 18.0%). Although levels of accumulated debris were relatively low overall, and unlikely to result in gut blockage, associated toxins might nevertheless represent a health risk for Diomedea albatrosses, compounding the negative impact of other human activities on these threatened species.

“…Las especies oceánicas registradas en nuestro estudio (albatros, petreles, tortugas marinas) presentan amplios rangos de distribución, y usan el área de estudio como sitio no reproductivo Silva Rodríguez et al, 2005;Copello et al, 2009Copello et al, , 2013González Carman et al, 2012). Las mayores amenazas a estas especies son la mortalidad incidental por enmallamiento relacionado a pesquerías y la polución costera fundamentalmente por la ingesta de plásticos (Lewison et al, 2014, Kuhn et al, 2015.…”

Tetrapod's diversity at the southeast Pampas as a tool for conservation planning. Despite advances in the understanding about the biodiversity in some regions, this is in general rather dispersed and has not been analyzed regarding their emergent properties and ordered in contexts to facilitate decision-making. The southeast of the Pampas shows an outstanding environmental diversity in a relatively restricted area, with a significant amount of information about biodiversity of Tetrapods. Our goal was to gather this information within a common framework, making a list of the relative abundance of species at each environment, highlighting species of conservation concern. We evaluated the complementarity among taxa (amphibians, reptiles, birds and mammals) in terms of composition, total number of species and number of threatened species. Our results on Tetrapods' diversity data shows that this small area harbor a number of species representative of Buenos Aires Province, 12 species of amphibians, 26 reptiles, 233 birds and 34 species of mammals, of which 41 are threatened and two endemic. The environments represented (grassland, dunes, mountains, wetlands, estuaries, marine, agroecosystems and urbanizations) contribute differently to the overall diversity of Tetrapods. The uneven distribution of species richness, threatened species and composition within each taxon among environments and among taxa highlights the usefulness of this type of analysis in the elucidation of the spatial variation of biodiversity and it should assists in territorial planning within a framework that optimizes the conservation of biodiversity.

“…In this fishery, the main component of discards (undersized hake) and offal (hake head, tail, and guts) could be assumed to have similar isotopic signatures than ice trawlers. However, given the very low level of overlapping with BBas during the temporal window analyzed (see Copello et al 2013;Copello unpubl. data), this fleet was considered negligible in terms of supplying any source of food to albatrosses.…”
