Trophic ecology of large pelagic fish in the Saint Peter and Saint Paul Archipelago, Brazil
(2019-01-01)
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, ...
Long-Term Stability in the Trophic Ecology of a Pelagic Forager Living in a Changing Marine Ecosystem
(Frontiers Media S.A., 2020-02)
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 ...
Isotopic niche plasticity in a marine top predator as indicator of a large marine ecosystem food web status
(Elsevier Science, 2021-07)
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 ...
Importance of jumbo squid Dosidicus gigas (Orbigny, 1835) in the pelagic ecosystem of the central Gulf of California
(Ecological Modelling, 2008)
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 ...
Trophic overlap between marine mammals and fisheries in subtropical waters in the western South Atlantic
(Inter-Research, 2020-04)
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 ...
Biodiversity, structure and trophic functioning of marine communities in Rapa Nui (Easter Island)
(2020)
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 ...
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 ...
