| genetic structure of populations of the threatened eastern massasauga rattlesnake, sistrurus c. catenatus: evidence from microsatellite dna markers. | throughout its distribution in north america, the threatened eastern massasauga rattlesnake (sistrurus c. catenatus) persists in a series of habitat-isolated disjunct populations of varying size. here, we use six microsatellite dna loci to generate information on the degree of genetic differentiation between, and the levels of inbreeding within populations to understand how evolutionary processes operate in these populations and aid the development of conservation plans for this species. samples ... | 1997 | 9421918 |
