Evolutionarily stable range limits set by interspecific competition.
A combination of abiotic and biotic factors probably restricts the range of many species. Recent evolutionary models and tests of those models have asked how a gradual change in environmental conditions can set the range limit, with a prominent idea being that gene flow disrupts local adaptation. We investigate how biotic factors, explicitly competition for limited resources, result in evolutio...
متن کاملThe influence of interspecific interactions on species range expansion rates
Ongoing and predicted global change makes understanding and predicting species' range shifts an urgent scientific priority. Here, we provide a synthetic perspective on the so far poorly understood effects of interspecific interactions on range expansion rates. We present theoretical foundations for how interspecific interactions may modulate range expansion rates, consider examples from empiric...
متن کاملTrophic interactions and range limits: the diverse roles of predation.
Interactions between natural enemies and their victims are a pervasive feature of the natural world. In this paper, we discuss trophic interactions as determinants of geographic range limits. Predators can directly limit ranges, or do so in conjunction with competition. Dispersal can at times permit a specialist predator to constrain the distribution of its prey-and thus itself-along a gradient...
متن کاملInterspecific Interactions among Gastrointestinal Helminths in Pikas of North America
Two helminth communities, comprising seven species in Ochotona princeps and five in O. collaris, were studied for site specificity and interspecific interactions. There were no cases of competitive exclusion, but four species pairs were found concurrently more often than by chance, possibly due to similarities in life cycles. One case of interactive site segregation was demonstrated. There was ...
متن کاملImpact of interspecific interactions on antimicrobial activity among soil bacteria
Certain bacterial species produce antimicrobial compounds only in the presence of a competing species. However, little is known on the frequency of interaction-mediated induction of antibiotic compound production in natural communities of soil bacteria. Here we developed a high-throughput method to screen for the production of antimicrobial activity by monocultures and pair-wise combinations of...
