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. Ecogenetics focuses on the relationship between genetics and ecology [3] and species' genetic responses to the environment. [4] [5] Genecology primarily focuses on an ecological perspective, looking at changes and interactions between species. It studies the relationships between genetic variation and environmental gradients within a species. Genecology is often referred to as ecological genetics. [6]
