Using delta C-13 stable isotopes to quantify individual-level diet variation
(SpringerNew YorkEUA, 2007)
Differential use of trophic resources between an exotic and a coexisting native snail
(2022-01-01)
Knowing the interactions between exotic and native species is essential to establish possible threats to the local fauna. In this study, we assessed the use of food resources and diet overlap between a recently introduced ...
Feeding preferences in aquatic invertebrates associated to Egeria densa in a tropical high-mountain lake
(Universidad de Costa Rica, 2020)
Differential use of trophic resources between an exotic and a coexisting native snail
(Springer Tokyo, 2021-08-11)
Knowing the interactions between exotic and native species is essential to establish possible threats to the local fauna. In this study, we assessed the use of food resources and diet overlap between a recently introduced ...
Trophic ecology of tadpoles in floodplain wetlands: combining gut contents, selectivity, and stable isotopes to study feeding segregation of syntopic species
(Springer, 2020-05-29)
Little consensus exists on the role of food partitioning in the organization of tadpole assemblages. We studied trophic ecology of syntopic tadpoles through the analysis of gut contents, selectivity, and stable isotopes ...
The isotopic composition and insect content of diet predict tissue isotopic values in a South American passerine assemblage
(Springer, 2013)
We analyzed the carbon and nitrogen isotopic
values of the muscle, liver, and crop contents (‘‘diet’’) of
132 individuals of 16 species of Chilean birds. The nitrogen
content of diet was tightly correlated with the ...
Macroinvertebrate trophic responses to nutrient addition in a temperate stream in South America
(E Schweizerbartsche Verlags, 2013-01)
The present continuous anthropogenic pressure has resulted in an enhancement of nutrient inputs into rivers and streams. This situation has worsened, mainly in agricultural areas, causing an accelerated eutrophication. ...
Assessing trophic interactions between pelagic predatory fish by gut content and stable isotopes analysis around Fernando de Noronha Archipelago (Brazil), Equatorial West Atlantic
(2021-01-01)
The objective of this study was to analyse the feeding habits and trophic interactions between four oceanic predatory fish around the Fernando de Noronha Archipelago (FNA), Brazil, in the western equatorial Atlantic ...
