Plasticity in the foraging behavior of male Southern Rockhopper Penguins (Eudyptes chrysocome) during incubation in the Falkland/Malvinas Islands
(Springer, 2018-09)
Environmental changes often affect the persistence of species or populations at different spatial and temporal scales. Thus, species must either adapt to these changes or experience negative impacts at the individual or ...
Foraging habits and levels of mercury in a resident population of bottlenose dolphins (Tursiops truncatus) in Bocas del Toro Archipelago, Caribbean Sea, Panama
A small and genetically isolated bottlenose dolphin (Tursiops truncatus) population resides year-round in the
Bocas del Toro Archipelago-Panama (BDT). Photo-identification and genetic data showed that this dolphin
population ...
Linking population trends of Antarctic Shag (Phalacrocorax bransfieldensis) and fish at Nelson Island, South Shetland Islands (Antarctica)
(Springer, 2015-08)
This study aims to provide consistent information to explain the steady declining trend in the number of breeding pairs of Antarctic shag Phalacrocorax bransfieldensis in two colonies on Nelson Island, South Shetland ...
Dietary overlap in inshore notothenioid fish from the Danco Coast, western Antarctic Peninsula
(Co-action Publishing, 2013-12)
We carried out a dietary overlap analysis between notothenioid species by examining the stomach contents of more than 900 specimens collected in a fish assemblage at the Danco Coast, western Antarctic Peninsula, in the ...
Does prey availability influence the foraging effort and breeding success in the Antarctic Shag Phalacrocorax bransfieldensis?
(China Ornithological Society, 2013-12)
Information on diet composition, foraging effort and breeding success of the Antarctic Shag (Phalacrocorax bransfieldensis) was obtained at three colonies on the Antarctic Peninsula, during the 1997/98 breeding season. ...
Billfish foraging along the northern coast of Chile during the Middle Holocene (7400-5900 cal BP)
(Elsevier, 2016)
Early maritime adaptation is well known from eastern South America; however, evidence for navigation and large marine fish exploitation, indicative of skilled foraging techniques, remains scarce. In the Atacama Desert, ...
Shags in Antarctica: their feeding behaviour and ecological role in the marine food web
(Cambridge University Press, 2006-03)
Feeding behaviour, ecological role in the marine food web and population trends of the Antarctic shag Phalacrocorax bransfieldensis and the South Georgia shag P. georgianus in Antarctica are analysed. The diving depths and ...
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 ...
Stable isotopes indicate differing foraging strategies in two sympatric otariids of the Galapagos Islands
(Journal of Experimental Marine Biology and Ecology, 2012)
The feeding behavior of marine predators varies with the level of competition to which they are exposed. Populations living in the same or overlapping geographic regions (sympatric) are generally subject to inter-specific ...
Isotopic niche partitioning between two small cetacean species
(Inter-Research, 2021-02)
Commerson’s dolphin Cephalorhynchus commersonii and Peale’s dolphin Lageno - rhynchus australis live in sympatry along the southwestern South Atlantic Ocean, suggesting the existence of some degree of habitat partitioning ...
