Mitigating future avian malaria threats to Hawaiian forest birds from climate change
Wei Liao, Carter T. Atkinson, Dennis LaPointe, Michael D. Samuel
2017, PLoS ONE (12) 1-25
Avian malaria, transmitted by Culex quinquefasciatus mosquitoes in the Hawaiian Islands, has been a primary contributor to population range limitations, declines, and extinctions for many endemic Hawaiian honeycreepers. Avian malaria is strongly influenced by climate; therefore, predicted future changes are expected to expand transmission into higher elevations and intensify and...
