Bluemask darters (Etheostoma akatulo) were sampled from the four drainages where extant populations of this narrowly endemic freshwater fish are known to exist. Population genetic diversity and structure were assessed at 10 microsatellite loci. All populations exhibited low levels of genetic variation, with expected heterozygosity ranging from 0.2 to 0.35.(More)
We isolated 21 microsatellite loci from Noturus flavipinnis, a federally threatened freshwater fish. Nine loci were polymorphic with an average of 1.48 alleles and an average observed and expected heterozygosity of 0.092 and 0.096, respectively. All loci conformed to Hardy–Weinberg expectations, and all pairs of loci showed no signs of genotypic(More)
