TLDR
As presas predominantes forarn o polvo comurn e peixes para grandes exernplares de E. marginatus da ilha Terceira foram obsewadas e s5io descritas.Abstract:
Entre 1992 e 1995, forarn colhidos e examinados 57 exernplares de E. marginatus da ilha Terceira. 0 s seus cornprirnentos totais variararn entre 60 e 138 crn corn duas categorias de tarnanho. 0 coeficiente de vacuidade observado foi de 44,0% para exernplares de rnMio porte e 31,3% para grandes exernplares. As presas predominantes forarn o polvo comurn e peixes. Duas posturas de caGa diferentes foram obsewadas e s5io descritas.read more

Fisheries Impacts on North Atlantic Ecosystems : Models and Analyses
TL;DR: A preliminary food web model of the Atlantic continental shelf adjacent to the southeastern United States was constructed using Ecopath with Ecosim, as a way to initiate a long-term process of integrating this knowledge, learning more about the structure and resiliency of the system, and helping to guide research priorities in the future.
