In ecology, a niche is the match ... It describes how an organism or population responds to the distribution of resources and competitors (for example, ...
Intraspecific competition is an interaction in population ecology, whereby members of the same species compete for limited resources. This leads to a reduction in fitness for both individuals, but the more fit individual survives and is able to reproduce. [1]
An autecological approach differs from ecosystem ecology, community ecology (synecology) and population ecology by greater recognition of the species-specific adaptations of individual animals, plants or other organisms, and of environmental over density-dependent influences on species distributions. [1]
The Society for Ecological Restoration defines restoration as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." [1] Restoration ecology is the academic study of the science of restoration, whereas ecological restoration is the implementation by practitioners. [19]
The effective population size (N e) is the size of an idealised population that would experience the same rate of genetic drift as the real population, whereby the latter, due mainly to the limited proportion of breeding individuals, has a normally larger census population size N. Idealised populations are based on unrealistic but convenient ...
The Leslie matrix is a discrete, age-structured model of population growth that is very popular in population ecology named after Patrick H. Leslie. [1] [2] The Leslie matrix (also called the Leslie model) is one of the most well-known ways to describe the growth of populations (and their projected age distribution), in which a population is closed to migration, growing in an unlimited ...
Applied ecology is an integrated treatment of the ecological, social, and biotechnological aspects of natural resource conservation and management. [2] Applied ecology typically focuses on geomorphology, soils, and plant communities as the underpinnings for vegetation and wildlife (both game and non-game) management.
Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology.Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.
