The Hawaiian Islands are home to some of the world’s most culturally valuable but imperiled forest birds, including brightly colored native honeycreepers, many of which are threatened or endangered. One of the major threats these birds face is avian malaria, which is spread by a species of introduced mosquito and can have death rates exceeding 90 percent. For decades, upper mountain forests have provided refuge for Hawaiian forest birds because mosquitoes (and thus the disease) could not survive the cooler temperatures. However, warming associated with climate change could change this. Scientists used climate data and an epidemiological model to evaluate the future impacts of avian malaria on Hawaiian forest birds...

A State Wildlife Action Plan is a comprehensive assessment of a state’s wildlife and wildlife-related issues submitted by the Fish and Wildlife Management agencies of every state. These plans lay out actions necessary to conserve wildlife and their habitat within each state and prevent endangered species listings. Congress has mandated that these action plans be reviewed and revised every ten years to identify the species of greatest conservation need within each state. In addition, these plans provide the basis for state access to funding from the Fish and Wildlife Service State and Tribal Wildlife Grants Program to target such species and enable effective conservation efforts. Our goal is to develop a better understanding...

FY2011Aspen populations are in decline across western North America due to altered fire regimes, herbivory, drought, pathogens, and competition with conifers. Aspen stands typically support higher avian biodiversity than surrounding habitats, and maintaining current distributions of several avian species is likely tied to persistence of aspen on the landscape. We are examining effects of climate change on aspen and associated avian communities in isolated mountain ranges of the northern Great Basin, by coupling empirical models of avian-habitat relationships with spatially-explicit landscape simulations of vegetation and disturbance dynamics (using LANDIS-II) under various climate change scenarios. We are addressing...
