CHANGES IN TECHNOLOGY HAVE DRIVEN INCREASED USE OF CONSERVATION GENETICS TO INFORM MANAGEMENT OF IMPERILED FRESHWATER MUSSELS
Quantifying genetic variation of imperiled species has been a concern of conservation agencies. Changing technology has led to increased use of genetic techniques for informing conservation of freshwater mussels. Early attempts to describe variation used morphological characteristics, especially shell shape. However, these traits are notoriously plastic, leading to poor resolution of species boundaries and among-population variation. Because biochemical genetic techniques describe variation at a small number of loci, they have limited abilities to resolve genetic diversity and divergence, and the presence of species boundaries. Phylogeographic studies and DNA barcoding to delimit species were feasible once DNA sequencing methods became inexpensive. Recent development of population genomic approaches promises to expand coverage of the genome and thus, provide higher resolution of population diversity and divergence, while also identifying signatures of natural selection. Over the past two decades, application of genetic principles for the conservation and recovery of imperiled species has greatly increased. This is seen in the development of recovery plans, creation of strategies for captive propagation and reintroduction, and studies examining biological factors such as gene flow and isolation among populations.
