Conservation genetics is a science that aims to apply genetic methods to deal with the maintenance, loss, and restoration of biodiversity. Researchers involved in conservation genetics come from a variety of fields including population genetics, molecular ecology and biology, evolutionary biology, and systematics. A short list of studies a conservation geneticist may research include:
- Phylogenetic classification of species, subspecies, geographic races, and populations, and measures of phylogenetic diversity and uniqueness.
- Identifying hybrid species, hybridization in natural populations, and assessing the history and extent of introgression between species.
- Population genetic structure of natural and managed populations, including identification of Evolutionary Significant Units (ESUs) and management units for conservation.
- Assessing genetic variation within a species or population, including small or endangered populations, and estimates such as effective population size (Ne).
- Measuring the impact of inbreeding and outbreeding depression, and the relationship between heterozygosity and measures of fitness (see Fisher's fundamental theorem of natural selection).
- Evidence of disrupted mate choice and reproductive strategy in disturbed populations.
- Forensic applications, especially for the control of trade in endangered species.
- Practical methods for monitoring and maximizing genetic diversity during captive breeding programs and re-introduction schemes, including mathematical models and case studies.
- Conservation issues related to the introduction of genetically modified organisms.
- The interaction between environmental contaminants and the biology and health of an organism, including changes in mutation rates and adaptation to local changes in the environment (e.g. industrial melanism).
- New techniques for noninvasive genotyping.
