Consideration of genetic relationships in management decisions for the endangered Anthony's riversnail, Leptoxis crassa anthonyi (Redfield, 1854) (Gastropoda: Pleuroceridae)

摘要: Anthony's riversnail, Leptoxis crassa anthonyi, is a federally endangered pleurocerid restricted to three natural populations in the Tennessee River drainage. Recovery plans organized into two management units, and called for specific numbers of downlisting or debiting Given that nothing was known about genetic structure these individuals were being randomly transplanted, we examined each population using COI mtDNA sequences All possessed unique sequence haplotypes, units identified recovery plan did not group accurately phylogenetic context. Potential decisions light our findings are discussed.
