One important hypothesis, in relation to the abundance of species, across geographical distributions, assumes that there are optimal sites (center of distribution) and sub-optimal sites (periphery) for survival and ...

The role of niche differences and competition is invoked when one finds coexisting species to be more dissimilar in trait composition than expected at random in community assembly studies. This approach has been questioned ...

Many generalist populations are composed of specialised individuals, whose niches are small subsets of the population niche. This 'individual specialisation' is a widespread phenomenon in natural populations, but until ...

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 ...

Understanding the effects of biodiversity on community persistence and productivity is key to managing both natural and production systems. Because rare species face greater danger of extinction, species evenness, a measure ...
