| 요약 | The southern sea otter (Enhydra lutris neires) and the Amargosa vole (Microtus californicus scirpensis) are two native California species listed under the Endangered Species Act due to substantial population declines associated with anthropogenic pressures. Though habitat loss is commonly the greatest threat to species survival, disease can be a neglected yet considerable contributing factor to population decline. In complex communities, abundant host populations can be a source for repeated spillover of multiple-host pathogens to scarce, threatened host populations. The purpose of this dissertation was to investigate the threat of two multiple-host pathogens to inform conservation management actions: hantaviruses in Amargosa voles and nasopulmonary mites in southern sea otters. Hantaviruses are globally distributed, rodent-associated viruses that can affect host fitness, potentially compounding challenges facing endangered rodents like the Amargosa vole. Nasopulmonary mites infest marine mammals worldwide and can cause signficant host pathology, potentially contributing to the death of southern sea otter individuals. Additionally, because little basic biology had been described for the Amargosa vole, it was necessary to summarize their basic natural history and ecology to allow managers to adequately undertake recovery planning. In the Amargosa vole community, hantaviruses do not appear to be a threat that requires management action at present, and instead recovery planning should focus on preserving habitat characteristics necessary for Amargosa vole survival. In contrast, nasopulmonary mites do represent an ongoing threat to southern sea otters with possible recurrent spillover from neighboring pinnipeds and should be considered when planning management actions. |
