In ecology, functional equivalence (or functional redundancy) is the ecological phenomenon that multiple species representing a variety of taxonomic groups can share similar, if not identical, roles in ecosystem functionality (e.g., nitrogen fixers, algae scrapers, scavengers). [1] This phenomenon can apply to both plant and animal taxa.
Studies relating to functional diversity and redundancy occur in a large proportion of conservation and ecological research. As the human population increases, the need for ecosystem function subsequently increases.
The award goes to individuals or organizations that make "outstanding achievements in scientific research and in so doing help to solve global environmental problems." In 2020 Walker was made an Officer (AO) in the General Division of The Order of Australia for "distinguished service to science, particularly to ecosystem ecology and research ...
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover [citation needed], and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
Graph shows principles of intermediate disturbance hypothesis: I. at low levels of ecological disturbance species richness decreases as competitive exclusion increases, II. at intermediate levels of disturbance, diversity is maximized because species that thrive at both early and late successional stages can coexist, III. at high levels of ...
An "ecological community" is a group of trophically similar, sympatric species that actually or potentially compete in a local area for the same or similar resources. [1] Under the Unified Theory, complex ecological interactions are permitted among individuals of an ecological community (such as competition and cooperation), provided that all ...

Functional diversity is widely considered to be "the value and the range of those species and organismal traits that influence ecosystem functioning" [3] In this sense, the use of the term "function" may apply to individuals, populations, communities, trophic levels, or evolutionary process (i.e. considering the function of adaptations).
