Genetic Analysis of Ozark Hellbenders Utilizing RAPD Markers

Ozark hellbenders (Cryptobranchus alleganiensis bishopi) are large aquatic salamanders found in flowing waters. The abundance of this species is thought to have declined over the long term. What had been the most abundant population, in Spring River, Arkansas, appears to have declined precipitously in the last decade. The possibility of supplementing the population through captive propagation has been suggested, raising concerns about genetic issues. Random amplified polymorphic DNA (RAPD) was evaluated for assessing genetic variability among and within populations of Ozark hellbenders...

Biochemical Genetics of Brook Trout in Georgia: Management Implications

Twenty-eight populations of brook trout (Salvelinus fontinalis) in Georgia were genetically compared using isozymes and their genetic relatedness determined. Eight populations (29%) were classified as southern based on fixation for CK-A2*122 allele, 2 (7%) populations were classified as northern based on fixation for CK-A2*100 allele, and the remaining 18 (64%) were northern-southern hybrid populations. All 8 southern populations shared some variant alleles with northern populations. Northern brook trout in Georgia had much greater genetic variation than southern brook trout, and hybrid...
