Introduced species are one of the main threats to biological diversity, but they can also facilitate native through mechanisms such as trophic subsidy.We quantified diet breeding kelp gulls (Larus dominicanus) and their consumption introduced green crab (Carcinus maenas) at five colonies located along over 600 km coastline in Patagonia, Argentina, analyzed differences rates among locations.Results based on pellet analysis (n = 961 pellets) showed that consumed crabs during most or part cycle...
Several studies have applied induced regurgitations to characterize the diet of cormorants, but none presented quantitative information indicating complete stomach contents were obtained. Our goal was test value for assessment and monitoring Imperial Cormorant (Phalacrocorax atriceps) diet. Stomach samples obtained from male female breeding adults bringing food back colony during chick rearing stage (n = 22) at Isla Arce, Argentina. Samples through regurgitation, immediately afterward each...
We assessed differences in diet composition between Imperial Cormorants (Phalacrocorax atriceps) breeding at Isla Arce and Vernaci Este, Golfo San Jorge, Argentina. Both colonies are located within the Patagonia Austral marine park, commercial trawl fisheries operate adjacent waters, thus knowledge of their food requirement is fundamental to assess potential conflicts monitor interactions. obtained stomach samples from 63 adult during chick-rearing period 2014: 32 31 Este. recorded 27 30...
The Argentine anchovy, Engraulis anchoita, plays a vital role as key prey species for several marine predators in the north Patagonian ecosystem of Atlantic Ocean. Reconstructing length and weight each consumed specimen is essential to provide detailed description trophic ecology top predators. Predictive linear regression equations were calculated stock anchovy estimate parameters length-weight relationships using measurements whole individuals diagnostic elements such otoliths, head bones...
