Temporal genetic variation of mitochondrial DNA and the female effective population size of red drum ( Sciaenops ocellatus) in the northern Gulf of Mexico
Abstract We studied genetic drift of mitochondrial DNA (mtDNA) haplotype frequencies in a natural population of red drum ( Sciaenops ocellatus ) from the northern Gulf of Mexico (Gulf). The amount of genetic drift observed across temporally adjacent year classes (1986–89) was used to estimate varian...
