A CONCEPTUAL MODEL TO FACILITATE AMPHIBIAN CONSERVATION IN THE NORTHERN GREAT PLAINS

摘要: As pressures on agricultural landscapes to meet worldwide resource needs increase, amphibian populations face numerous threats including habitat destruction, chemical contaminants, disease outbreaks, wetland sedimentation, and synergistic effects of these perturbations. To facilitate conservation planning, we developed a conceptual model depicting elements critical for in the northern Great Plains. First, linked upland, wetland, landscape features specific ecological attributes. Ecological attributes included adult survival; reproduction survival metamorphosis; successful dispersal recolonization. Second, ecosystem drivers, stressors, region each attribute. Lastly, summarized information that work concert influence maintenance viable genetically diverse amphib­ ian While our focus was Plains, can be tailored other geographic regions taxa.
