... Patterns of niche partitioning can result from local ecological interactions (e.g. interspecific competition) occurring within a contemporary time frame (realized niche partitioning). Alternatively, they may represent the end product of historical processes acting over long time frames (fundamental niche partitioning). Niche partitioning is often detected by analysing patterns of resource use with ...
... Non‐random species associations occur in naturally sampled parasite communities. The processes resulting in predictable community structure (e.g. particular host behaviours, cross‐immunity, interspecific competition) could be affected by traits that vary within a parasite species, like growth or antigenicity. We experimentally infected three‐spined sticklebacks with a large tapeworm (Schistocephal ...
... Models of ecological community assembly predict how communities of interacting organisms may be shaped by abiotic and biotic factors. Competition and environmental filtering are the predominant factors hypothesized to explain community assembly. This study tested the effects of habitat, phylogenetic and phenotypic trait predictors on species co‐occurrence patterns and abundances, with the endemic ...

Abstract:
... Numerous processes influence community structure. The relative importance of these processes is thought to vary with spatial, temporal and taxonomic scales: density‐dependent interactions are thought to be most important at small scales; at intermediate scales, environmental conditions may be the most influential factor; and biogeographic processes are thought to be of greater importance at larger ...
