Genetic ecology is the study of the stability and expression of varying genetic material within abiotic mediums. [1] Typically, genetic data is not thought of outside ...
Ecological genetics is the study of genetics in natural populations. It combines ecology, evolution, and genetics to understand the processes behind adaptation. [1] It is virtually synonymous with the field of molecular ecology.
In evolutionary ecology, an ecotype, [note 1] sometimes called ecospecies, describes a genetically distinct geographic variety, population, or race within a species, which is genotypically adapted to specific environmental conditions.
Genecology is a branch of ecology which studies genetic variation of species and communities compared to their population distribution in a particular environment. [1] [2] It is closely related to ecogenetics, but genecology focuses primarily on an ecological perspective, looking at changes and interactions between species, while ecogenetics focuses more on species' genetic responses to the ...
Genetics is the study of genes, genetic variation, and heredity in organisms. [ 1 ] [ 2 ] [ 3 ] It is an important branch in biology because heredity is vital to organisms' evolution . Gregor Mendel , a Moravian Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically.
Population bottleneck followed by recovery or extinction. A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts; or human activities such as genocide, speciocide, widespread violence or intentional culling.
A genetic species as defined by Robert Baker and Robert Bradley is a set of genetically isolated interbreeding populations. This is similar to Mayr's Biological Species Concept, but stresses genetic rather than reproductive isolation. [47] In the 21st century, a genetic species could be established by comparing DNA sequences.
Biotic homogenization is the process by which two or more spatially distributed ecological communities become increasingly similar over time. This process may be genetic, taxonomic, or functional, and it leads to a loss of beta (β) diversity. [1]
