| mixed-source reintroductions lead to outbreeding depression in second-generation descendents of a native north american fish. | reintroductions are commonly employed to preserve intraspecific biodiversity in fragmented landscapes. however, reintroduced populations are frequently smaller and more geographically isolated than native populations. mixing genetically, divergent sources are often proposed to attenuate potentially low genetic diversity in reintroduced populations that may result from small effective population sizes. however, a possible negative tradeoff for mixing sources is outbreeding depression in hybrid of ... | 2011 | 21917046 |
