Population genetics and the dynamics of conservation

  • Chapter
Biotic Diversity and Germplasm Preservation, Global Imperatives

Part of the book series: Beltsville Symposia in Agricultural Research ((BSAR,volume 13))

Abstract

Dynamic evolution of natural populations implies that collections made at any one time and statically maintained cannot capture all potentially useful alleles or efficiently save useful alleles. The structure of mating demes and the presence of heterogeneous selection force species to evolve new alleles, traits, and populations continuously, some of which may be useful for breeding. Breeding also is a dynamic system, and breeders can develop different populations and use new gene effects to create selective responses to new economic demands or to new requirements for ecological adaptability. Static collections, however, are not necessarily easy to use. The genetic management of both natural and breeding populations can involve single or multiple populations selected for homogeneous or diverse objectives. Through collection and maintenance programs that mediate between evolution and breeding, germplasm conservation can include the active development of collections and the creation of diversity.
