摘要: Admixture and introgression have varied effects on population viability fitness. might be an important source of new alleles, particularly for small, geographically isolated populations. However, admixture also cause outbreeding depression if populations are adapted to different ecological or climatic conditions. Because the emerging use translocation as a conservation wildlife management strategy reduce genetic load (termed rescue), possible practical consequences (Bouzat et al. 2009; Hedrick & Fredrickson 2010). Importantly, local adaptation properties individual loci epistatic interactions among rather than genomes. Likewise, outcome rescue depend fitness introduced alleles. In this issue Molecular Ecology, Miller (2012) model-based, genomic analyses document locus-specific recent in bighorn sheep within National Bison Range refuge (NBR; Montana, USA). They find subset alleles associated with increased NBR sheep, some which experienced accelerated following their introduction. These mark regions genome that could constitute basis successful rescue. Although frequently used study selection (e.g. Hohenlohe 2010; Lawniczak 2010), constitutes novel application analytical framework management. Moreover, detailed demographic data available provide rare powerful information allow more robust inference is often possible.
