Variación inter e intraespecífica del ciclo respiratorio durante las inmersiones en tres especies de cormoranes patagónicosInter- and intraspecific variation of the breathing cycle during diving in three species of patagonian cormorants
(Asociación Ornitológica del Plata, 2009-12)
En tres sitios de nidificación ubicados en la costa patagónica de Argentina (Punta Loma, Caleta Malaspina y Puerto Deseado) se estudió en forma comparada la variación inter e intraespecífica de la relación entre la duración ...
Cormorant pellets as a tool for the knowledge of parasite-intermediate host associations and nematode diversity in the environment
(Versita, 2019-11-05)
Anisakids are usually acquired through the diet. Cormorant pellets are useful to detect both parasite larval stages, and prey items which could act as intermediate hosts in the environment. The current study provides ...
Long necks enhance and constrain foraging capacity in aquatic vertebrates
(The Royal Society, 2017-11)
Highly specialized diving birds display substantial dichotomy in neck length with, for example, cormorants and anhingas having extreme necks, while penguins and auks have minimized necks. We attached acceleration loggers ...
Seabird use of discards and incidental captures at the Argentine hake trawl fishery in the Golfo San Jorge, Argentina
(Inter-research, 2006-07-03)
We studied discard use and incidental mortality of seabirds attracted to high-sea trawl vessels operating in the Golfo San Jorge, Argentina, during the height of the fishing season in 2003 and 2004. Fourteen seabird species ...
Spatial overlap between foraging seabirds and trawl fisheries: Implications for the effectiveness of a marine protected area at Golfo San Jorge, Argentina
(Cambridge University Press, 2010-09)
La evaluación de las actividades humanas y la comprensión de su interacción con las aves marinas son importantes para la elaboración adecuada de esquemas de planificación para la conservación. Se analizó el uso espacial ...
Seabird attendance and incidental mortality at shrimp fisheries in Golfo San Jorge, Argentina
(Inter-Research, 2011-06)
Many seabirds are attracted to trawl vessels to make use of fishery waste, and often this attraction results in increased incidental mortality. We assessed seabird attendance and associated incidental mortality at the ...
Foraging patterns of breeding Dolphin Gulls Larus scoresbii at Punta Tombo, Argentina
(Wiley Blackwell Publishing, Inc, 2005-06)
The Dolphin Gull Larus scoresbii is a little‐known, rare species endemic to southern South America. Knowledge of its feeding ecology is essential for development of management and conservation strategies. To obtain information ...
Construction of energy landscapes can clarify the movement and distribution of foraging animals
(The Royal Society, 2011-09-07)
Variation in the physical characteristics of the environment should impact the movement energetics of animals. Although cognizance of this may help interpret movement ecology, determination of the landscape-dependent energy ...
Marine protected areas, spatial scales, and governance: implications for the conservation of breeding seabirds
(Wiley, 2009-08)
As in many regions worldwide, seabird colonies in Argentina are important conservation targets of marine protected areas (MPAs). Seabirds are wide ranging, often crossing jurisdictional boundaries during foraging. Using a ...
Flexible paddle sheds new light on speed: A novel method for the remote measurement of swim speed in aquatic animals
(Inter-Research Science Center, 2008-12)
Speed is a key determinant of energy expenditure in free-living animals, and particularly in marine vertebrates, where power requirements for swimming increase as a cubed function of the speed. However, current devices ...
