All data were combined for a principal components analysis that discriminated two main groups: three generalist species that live in all types of habitat, and five specialist species that ranged from rather scarce to extremely rare and are found only in unaltered habitats. The three generalist ...

Theory suggests that specialist species are more competitive in natural communities. However, empirical work has shown that specialist species are declining worldwide due to habitat loss and fragmentation. We addressed the question of the coexistence of specialist and generalist species with a spatially ...
Intensified human land use continues to increase habitat loss and fragmentation, and leads to a homogenization of biodiversity. Specialized species with narrow niches seem to be declining more rapidly than generalist species. Veteran trees offer an excellent model system for testing the responses of hab...
Specialist and generalist life histories are expected to result in contrasting levels of genetic diversity at the population level, and symbioses are expected to lead to patterns that reflect a shared biogeographic history and co-diversification. We test these assumptions using mtDNA sequencing and a ...

We examine the differential impact of specialist and generalist seed predators in the reproductive output of both species and evaluate how those effects relate with plant rarity. Furthermore, we assess how insect predation pressure is correlated with plant traits indicative of size and fecundity and ...
Definitions of our species as unique within the hominin clade have tended to focus on differences in capacities for symbolism, language, social networking, technological competence and cognitive development. More recently, however, attention has been tur
Why generalist and specialist species coexist in nature is a question that has interested evolutionary biologists for a long time. While the coexistence of specialists and generalists exploiting resources on a single ecological dimension has been theoretically and empirically explored, biological systems wit...
