Plants have evolved numerous defensive traits that enable them to resist herbivores. In turn,
this resistance has selected for herbivores that can cope with defenses by either avoiding …

Reproductive interference is interspecific sexual interactions that are costly to at least one
species involved. Although many studies have reported a substantial fitness cost associated …

Bacterial endosymbionts are known as important players of the evolutionary ecology of their
hosts. However, their distribution, prevalence and diversity are still largely unexplored. To …

Endosymbiotic reproductive manipulators are widely studied as sources of postzygotic
isolation in arthropods, but their effect on prezygotic isolation between genetically …

Some plants are able to accumulate in their shoots metals at levels that are toxic to most
other organisms. This ability may serve as a defence against herbivores. Therefore, both …

Few studies have tested how plant quality and the presence of competitors interact in
determining how herbivores choose between different leaves within a plant. We investigated …

Wolbachia are maternally-inherited bacteria that induce cytoplasmic incompatibility in many
arthropod species. However, the ubiquity of this isolation mechanism for host speciation …

Plant defense suppression is an offensive strategy of herbivores, in which they manipulate
plant physiological processes to increase their performance. Paradoxically, defense …

Herbivores select host plants depending on plant quality and the presence of predators and
competitors. Competing herbivores change host plant quantity through consumption, but …

Competition for food and reproductive interference (negative interspecific sexual
interactions) have been identified as major drivers of species exclusion. Still, how these …
