Linking modern coexistence theory and contemporary niche theory

Thus we can define an equalizing mechanism as any process that reduces the average fitness difference between species; and a stabilizing mechanism as any process that red ...

Ecological Role of Dry-Habitat Chimpanzees (Pan troglodytes

Patch focals allow for the observation of all animals within a study area; capture resources that are not used by the study species; and are ...

Species coexistence and the superior ability of an invasive species

To quantify whether there was evidence for spillover effects adjacent to cordgrass–mussel beds, we conducted a survey in August 2007 to compare the abundance of adult crabs in low cobble habitats at sites with cordgrass-ribbed mussel beds in the mid zone vs. sites without beds in the mid zone. We co ...
