Amphibian trophic ecology in increasingly human-altered wetlands
(Herpetological Conservation and Biology, 2015-12)
Habitat destruction and alteration are among the major causes of worldwide amphibian declines. Resource limitation in altered environments can potentially affect trophic ecology of amphibians and contribute to decline. In ...
Análise do conteúdo estomacal confirma a plasticidade alimentar de uma espécie de peixe generalista em um rio tropical
(Associação Brasileira de Limnologia, 2020-09-02)
In this paper, we compared the diet composition of the South American silver croaker, Plasgioscion squamosissimus in preserved and impacted areas (agrarian land use) of an Amazonian river. Our objective was to quantify the ...
Individual diet specialisation in sparrows is driven by phenotypic plasticity in traits related to trade-offs in animal performance
(Wiley Blackwell Publishing, Inc, 2019-01)
Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population niches should exhibit greater IS than ...

Dieta del surel Trachurus lathami - región norpatagónica
Rough scad Trachurus lathami is a key pelagic fish in the Argentinean continental shelf (ACS, south-west Atlantic Ocean), with recent increases in abundance. It is a main prey of fishes and marine mammals, and shares the ...
Quality and digestibility of food ingested by various trophic fish groups in the Upper Paraná River floodplain
(Universidad de Costa Rica, 2011)
Buoyancy studies of three morphs of the Antarctic fish Trematomus newnesi (Nototheniidae) from the South Shetland Islands
(Springer, 2010-06)
Phenotypic plasticity, a widespread phenomenon in boreal freshwater fishes, is less apparent in the marine realm and the organism-environment interactions producing this variation are undetermined. A sample of 40 specimens ...
Variation in trophic resources in female South American sea lions at a small geographic scale
(John Wiley & Sons Inc, 2021-01)
Difference among colonies in the population structure of otariids can be driven by philopatry and/or by specializations in the foraging ecology of females. In northern Patagonia, the South American sea lion (SASL) shows ...
Inter-annual variation in the trophic niche of Magellanic penguins Spheniscus magellanicus during the pre-molt period in the Beagle Channel
(Inter-Research, 2020-11)
Inter-annual variations in the diets of seabirds are often a reflection of resource availability, with population dynamics and community structure implications. We investigated the trophic niche of Magellanic penguins ...
