Habitat fragmentation and degradation have led to a proliferation of small and isolated populations that are vulnerable to genetic erosion. Reduction in habitat and concomitant declines in population connectivity can expediate the collapse of species that exist as natural metapopulations. In recent years, Allegheny woodrats (Neotoma magister) have experienced local extirpations and declines in genetic diversity across their range due to disease-related mortality, reduced food availability, and disruption of connectivity among subpopulations. In response, we developed a captive-breeding program to facilitate genetic management of isolated woodrat populations in Indiana. Between 2010 and 2012, 27 captive-reared individuals were released to four …
Identification Of Segregating Haplotypes Of The Major Histocompatibility Complex In Cranes, Susan I. Jarvi, George F. Gee, W. Elwood Briles, Marcia M. Miller
Identification Of Segregating Haplotypes Of The Major Histocompatibility Complex In Cranes, Susan I. Jarvi, George F. Gee, W. Elwood Briles, Marcia M. Miller
Proceedings of the North American Crane Workshop
The major histocompatibility complex (Mhc) is thought to exist in all vertebrate species. In most species, a high degree of polymorphism is maintained in this region at mUltiple loci which encode molecules that serve in the presentation of foreign antigens to T lymphocytes (Klein 1986, Miller 1991). In this investigation, serological and recombinant DNA techniques are being used to investigate genetic diversity at the Mhc in several species of cranes, to investigate questions of paternity in some instances, and to develop practical methods for determining Mhc haplotype •. Blood samples are provided by the Patuxent Wildlife Research Center (PWRC), Laurel, …
The Plight Of Cranes: A Case Study For Conserving Biodiversity, J. Christopher Haney, Mark E. Eiswerth
The Plight Of Cranes: A Case Study For Conserving Biodiversity, J. Christopher Haney, Mark E. Eiswerth
Proceedings of the North American Crane Workshop
Cranes provide an exemplary case for evaluating conservation policy because (1) they are a charismatic group with high public visibility, (2) as migratory vertebrates they provide an umbrella for the protection of aquatic habitats and a wider set of species, (3) they are a widely-distributed avian family, consequently protection efforts have favored international cooperation, (4) genetic and taxonomic relationships have been studied, and (5) populations of at least 7 crane species are threatened, endangered, or otherwise considered at direct risk. We use comparisons among the world's cranes to show how biogeographic, taxonomic, and genetic data bases can be linked for …
