Ecosystem trophic structure and energy flux in the Northen Gulf of California, Mexico
(Ecological Modelling, 2004)
Using the Ecopath with Ecosim software, a trophic structure model of the Northern Gulf of California was constructed to represent the main biomass flows in the system. It was based mostly on bibliographic data and provides ...
Feeding habits of two deep-sea sharks from central-northern Chile: hooktooth dogfish Aculeola nigra (Etmopteridae) and dusky catshark Bythalaelurus canescens (Scyliorhinidae)
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2010)
Influence of land use on the trophic niche overlap of dung beetles in the semideciduous Atlantic forest of Argentina
(Wiley-liss, Div John Wiley & Sons Inc, 2018-11)
The degradation and replacement of natural ecosystems affect species abundance, diversity and interspecific interaction through the modification of resource availability and environmental conditions. Land uses preserving ...

Dusky Dolphin Trophic Ecology: Their Role in the Food Web
(Elsevier, 2010)
Like most top predators, dusky dolphins (Lagenorhynchus obscurus) may play different roles in marine ecosystems, although they are still poorly known. Dusky dolphins are an integral part of several marine ecosystems of the ...
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 ...
Partitioning the relative fitness effects of diet and trophic morphology in the threespine stickleback
(Evolutionary Ecology Ltd, 2011-07-01)
Background: Numerous models show that if morphology and diet are correlated, frequency-dependent competition will lead to fitness differences among phenotypically dissimilar individuals within a species.Hypothesis: Selection ...
