Multi‐infections may result in either competitive exclusion or coexistence on the same host of pathogen genotypes belonging to the same or different species. Epidemiological consequences of multiple infections, particularly how the development and transmission of a pathogen can be modified by the presence of another pathogen, are well documented. However, understanding how life history strategies...
In species with obligate sexual reproduction, scarcity of males can occasionally limit female reproductive success. It is unclear, however, whether this impacts population‐level persistence. Sexually deceptive orchids attract mate‐searching male insects who lose time, mating opportunities and may even become sperm depleted by mating with flowers. These insects are almost exclusively haplodiploid,...
Understanding the relative contribution of different biotic interactions in shaping species assemblages constitutes a major goal in community ecology, and consequently, multiple methods aimed at inferring the nature of these associations have emerged during the last decade. In this framework, the stress‐gradient hypothesis (SGH) predicts that prevalent biotic interactions shift from competition to...
While models of species coexistence largely focus on how competition defines biological communities, over recent decades, a number of studies show positive plant–plant species interactions (facilitation) can also promote stable coexistence. The long‐lived, co‐dominant shrubs California buckwheat Eriogonum fasciculatum and California sagebrush Artemisia californica share a well‐documented positive...
