Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species' niches. However, ...

Tropical rainforests support the greatest diversity of small mammals in the world, yet we have little understanding about the mechanisms that promote the coexistence of species. Diet partitioning can favor coexistence by ...

Variation in fitness across individuals is central to population growth, species coexistence and evolution by natural selection. Fitness variation associated with resource use is hugely consequential, but how this variation ...

Saurians use differentially three dimensions of the ecological niche: spatial, temporal, and trophic niche to mini-mize or avoid competition. During dry season of 2006, we compared resource partitioning in two saurian ...

Esta tese gravita em torno da ideia de que indivíduos de uma mesma espécie são ecologicamente diferentes. Apesar de esse fato não parecer surpreendente, a teoria ecológica tem historicamente negligenciado a variação ...

Ontogenetic shifts from an insectivorous diet towards an herbivorous one are well known in lizards. Energetic, behavioral and morphological factors have been linked to this pattern, but the latter have received less ...

O nicho ecológico das espécies depende de fatores ecológicos e evolutivos. Espécies filogeneticamente próximas podem apresentar conservatismo de nicho, mantendo suas características ecológicas ancestrais. Alternativamente, ...
