Molecular ecology is an holistic interdisciplinary approach combining molecular biology and ecology to treat the relationship between organisms and their environment at the genes’ level. This method permits the analysis of the influence that genetic variation exercises on the ecological process, vice versa. For instance, how environmental changes affect the genetic makeup of populations.

Some of the important topics include population genetics, conservation genetics and evolutionary ecology. Population genetics is related to the genetic variation within or among populations hence this enables it to interpret the patterns of gene flow, genetic drift, and adaptation. In these analyses, some important techniques that will be included are microsatellite analysis, DNA sequencing, and GWAS.

These studies are integral parts of molecular ecology, reflecting the concern that genetic preservation is maintained within endangered species and populations to avoid inbreeding and the loss of genetic variation. Molecular tools may be helpful tools in estimating the genetic health of populations, identifying critical habitats, and methodologies for effective conservation.

Evolutionary ecology is, therefore, the study of how genetic changes in species influence their ecological roles and interactions: adaptation to environmental pressures and impacts of climate change. These adaptations can then be used as a molecular basis for predicting how species might respond to further changes in the environment.
