Trophic relationships of large pelagic predators can determine the structure and dynamics of oceanic food webs. The feeding habits and trophic ecology of five large pelagic fish (Acanthocybium solandri, Coryphaena hippurus, ...

Natural or human-induced environmental changes can modify the structure of ecological communities and thus alter food web interactions. After the collapse of hake stocks (Merluccius hubbsi) provoked by fisheries over the ...

As marine ecosystems are harvested or modified by anthropogenic or natural factors, there is an increasing demand for indicators of trophic web health or status. The Magellanic Penguin (Spheniscus magellanicus) is a widely ...

The Humboldt squid is an important predator in the pelagic ecosystem of the central Gulf of California to the commercial catch of this species has increased over the past decade, probable due to a decrease of several top ...

Marine mammals and humans are apex predators and both may compete for fish in ecosystems under continuous fishing pressure. We assessed the degree of trophic overlap between prey species found in the diet of 5 marine mammals ...

Coral reef ecosystems harbor a high biodiversity around the world, supporting a large amount of ecosystem services. Rapa Nui is a remote oceanic island situated in the Central South Pacific Ocean, and its coral reefs ...

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 ...
