Abstract Detail
Integrative species delimitation: incorporating multiple types of data Pettengill, James [1], Neel, Maile [2]. A sequential approach using genetic and morphological analyses to test species status: The case of the United States federally endangered Agalinis acuta (Orobanchaceae). Given that inaccurate taxonomy can have negative consequences for species of conservation concern and result in erroneous conclusions regarding macroecological patterns, efficient methods for resolving taxonomic uncertainty are essential. To assess the evolutionary distinctiveness of the federally endangered plant species Agalinis acuta (Orobanchaceae), we describe and implement a sequential approach that begins with the most restrictive criteria of genealogical exclusivity. Because of the possibility that incomplete lineagesorting is responsible for the lack of genealogical exclusivity among A.acuta individuals, we then conducted intensive population level analyses based on 21 microsatellite loci and 61 morphological traits. Through this successive approach, we found insufficient evidence to support the evolutionary distinctiveness of the listed taxon A. acuta. We recommend that it be synonymized under A. decemloba and also conclude that the taxon that would now include A. acuta is deserving of protection under the Endangered Species Act. Broader Impacts:
