Parasites As Probes For Biodiversity, Scott Lyell Gardner, Mariel L. Campbell
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
Cestodes of the genus Linstowia, parasitic in marsupials, show patterns of coevolution and ancient historical-ecological connections. Correlated with the breakup of the austral landmasses (Gondwanaland) of the Neotropical and Australian regions from the Antarctic continent, the age of this host-parasite community is estimated to be between 60 and 70 million years old. Based on the data from the survey of parasites of mammals from throughout Bolivia and from the phylogenetic analysis of the cestodes, we urge the planners of biodiversity preserves in the neotropics to consider the Yungas of Bolivia as a region that supports an ancient ecological community …
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 …
