Using Haplotype Information for Conservation Genomics

Abstract

The particular combinations of alleles that define haplotypes along individual chromosomes can be determined with increasing ease and accuracy by using current sequencing technologies. Beyond allele frequencies, haplotype data collected in population samples contain information about the history of allelic associations in gene genealogies, and this is of tremendous potential for conservation genomics. We provide an overview of how haplotype information can be used to assess historical demography, gene flow, selection, and the evolutionary outcomes of hybridization across different timescales relevant to conservation issues. We address technical aspects of applying such approaches to nonmodel species. We conclude that there is much to be gained by integrating haplotype-based analyses in future conservation genomics studies.
