The herbage productivity of tall fescue in the Pampas region of Argentina is correlated to its ecological niche
(Wiley, 2016-09)
Since its introduction in the 1950s, tall fescue has spread throughout the Pampas region of Argentina to become naturalized in much of this region. Its annual forage mass productivity shows significant differences among ...
The importance of biotic interactions in species distribution models: a test of the Eltonian noise hypothesis using parrots
(Wiley-blackwellHobokenEUA, 2014)
Smooth, striated, or rough: how substrate textures affect the feeding performance of tadpoles with different oral morphologies
(2020-03-01)
For grazing animals that share spatial and alimentary resources, the relationship between differences in oral morphology and the physical properties of substrates can help explain how and where species forage. The substrates ...
Feeding ecomorphologies in the fish genus Herichthys (Perciformes: Cichlidae) based on stomach content and lower pharyngeal jaw shape
(Universidad de Costa Rica, 2019)
Feeding habits of two deep-sea sharks from central-northern Chile: hooktooth dogfish Aculeola nigra (Etmopteridae) and dusky catshark Bythalaelurus canescens (Scyliorhinidae)
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2010)
A closer look at the main actors of Neotropical floodplain food webs: functional classification and niche overlap of dominant benthic invertebrates in a floodplain lake of Paraná River
(Fundaçao Zoobotanica Rio Grande Sul, 2016-04)
Functional classifi cation of animals is necessary to enhance the predictive power of food web models. However, while there is a large database for functional classifi cation of benthic invertebrates (Functional Feeding ...
Trophic interactions and isotopic niche of octopuses and sea stars in North Patagonia
(Springer, 2020-03)
Coexistence of species is associated with differentiation of niches and partitioning of resources, which lessen niche overlap and the intensity of competition. Here, we used stable isotope analysis to evaluate and compare ...
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 ...
