We observed variation in ability to colonize the rhizosphere amongst Metarhizium species. However, regardless of whether the Metarhizium species was a generalist or specialist insect pathogen, all strains tested retain ancestral ability to associate with plant roots.

Host-use trade-offs displayed by generalist and specialist sister species of the genus Helicoverpa were evaluated to examine the relationship between maternal choice and offspring performance. The prediction of optimal oviposition theory, that females will choose to lay eggs on plants on which their ...
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 ...
The impact of pre-dispersal seed predators on the reproductive output of both study plants was moderate and, in general, varied within and between habitats within each species. In areas of sympatry, the two plants suffered seed losses of the same magnitude to generalist and specialist predators ...

Bayesian species delimitation reveals generalist and specialist parasitic wasps on Galerucellabeetles (Chrysomelidae): sorting by herbivore or plant host Peter A Hambäck, Elisabet Weingartner, Lars Ericson, Lisa Fors, Anna Cassel-Lundhagen, Johan A Stenberg & Johannes Bergsten BMC Evolutiona...
Some specialist insects feed on plants rich in secondary compounds, which pose a major selective pressure on both the phytophagous and the gut microbiota. However, microbial communities of toxic plant feeders are still poorly characterized. Here, we show the bacterial communities of the gut of two...
Specialist or generalist? It depends.

However, for two groups in particular, Telonemia and Cryothecomonas, some species level taxa showed more restricted distributions. For example, several phylotypes of Telonemia favoured open waters with lower nutrients such as the Canada Basin and offshore of the Mackenzie Shelf. In summary, we...
