Genetic ecology is a branch of evolutionary biology that looks at genetic variation among species and populations. It works to understand the evolutionary processes that shape genetic variation, including natural selection, genetic drift, and gene flow. It is also interested in the effects of environmental factors on genetic variations.

Most of genetic ecology is done using field observations and experiments but it also incorporates theoretical approaches and population genetics. Field observations involve looking at different populations of animals to compare their behavior, diet, phenotypes, and reproductive strategies. Experiments are designed to test how different populations react to various environmental conditions or methods of management. Theoretical models look at the ways in which different parts of the environment or different populations interact and how they affect each other. Population genetics looks at how genetic variation is distributed among members of a population, and how that distribution changes over time.

Genetic ecology is also interested in how human activities, such as conservation and food production, affect genetic variation. It looks at how human activities can affect the spread of genes among different populations, as well as how human activities affect the diversity of genetic variation.

Genetic ecology has important implications for conservation. It can help us understand the best ways to manage wildlife populations and habitats to protect their genetic diversity. By looking at the genetic variation among populations, we can also better understand why some species are more resilient and adaptable than others. This is particularly important as climate change and other environmental changes, such as land use changes, have the potential to drastically reduce genetic variation. Genetic ecology can help us identify which species are most vulnerable to these changes and what conservation strategies are most appropriate for them.
