Evolutionary Genetics of Artificial Refugium Populations of an Endangered Species, the Desert Pupfish

Four artificial populations of an endangered fish species, Cyprinodon macularius, the desert pupfish, were surveyed for allozyme variation at the products of 39 presumptive structural gene loci. When compared to five remnant natural populations of the same species, some divergence in specific allele frequencies in the refugium populations were detected. The comparison revealed little overall divergence between the refugium populations and their natural progenitors. There was no apparent loss of average genic heterozygosity in the refugium populations. Results suggest that artificial refugia for endangered fish species are a biologically valid component of their management and conservation.
