Concepts

The concept that co-occurring species occupy distinct positions in multidimensional nutrient space to minimize competition and facilitate coexistence

A species that has a disproportionately large effect on its environment relative to its abundance and whose presence/absence significantly affects ecosystem structure and function

Theory that predicts patterns of distribution, abundance, and energetics using instantaneous values of community state variables including total area, total abundance, total species richness, and tota...

Theory suggesting that offspring sex ratios might vary according to maternal condition, hence females should vary the sex of their offspring according to their ability to physically invest in their of...

Theory that animals distribute themselves among habitat patches in proportion to resource availability, with high-quality patches becoming occupied first and animals moving to lower-quality patches as...

Biogeographic classification of species based on their broader distributional affinities and evolutionary origins

Sapsucker-fungus partnership that strongly influences the avian community by providing nest sites
