Influence of microhábitat on the trophic ecology of two leptodactylids from northeastern Argentina.
(Herpetologists League, 2004-12)
We analyzed trophic ecology and its relationship with environmental variables for two leptodactylid species, Leptodactylus latinasus and L. bufonius (Anura: Leptodactylidae). The two species are common around Corrientes ...
Food niche overlap between two sympatric leaf-litter frog species from Central Amazonia
(Sociedade Brasileira de Zoologia, 2015)
Ecological singularity of temperate mesopredatory myliobatoid rays (Chondrichthyes: Myliobatiformes)
(Csiro Publishing, 2016-06)
Many myliobatoid rays are important mesopredators, having significant effects on coastal benthic communities. In tropical and subtropical high-diversity oligotrophic ecosystems, they partition their trophic resources, which ...
Trophic interactions between brown and south polar skuas at Deception Island, Antarctica
(Springer, 2012-02)
It is broadly accepted that the brown skua (Stercorarius antarcticus lonnbergi) competitively excludes the south polar skua (S. maccormicki) from penguin colonies when breeding sympatrically, forcing the latter to feed on ...
Functional traits and environmental conditions predict community isotopic niches and energy pathways across spatial scales
(2018-10-01)
Despite ongoing research in food web ecology and functional biogeography, the links between food web structure, functional traits and environmental conditions across spatial scales remain poorly understood. Trophic niches, ...
Human-modified landscapes narrow the isotopic niche of neotropical birds
(Springer, 2021-04-09)
Deforestation and habitat loss resulting from land use changes are some of the utmost anthropogenic impacts that threaten tropical birds in human-modified landscapes (HMLs). The degree of these impacts on birds' diet, ...
Feeding ecomorphologies in the fish genus Herichthys (Perciformes: Cichlidae) based on stomach content and lower pharyngeal jaw shape
