Summary: Avian malaria in Hawaii, an introduced disease vectored by non-native mosquitoes, has led to the extinction or population decline of many native Hawaiian birds. Avian malaria is lethal to most Hawaiian birds, but a few species have developed resistance to the disease and can persist in disease hot zones. Identifying the genes that allow those birds to survive malaria will provide invaluable information on how they are adapting to the threat and provide insight into conservation strategies to prevent additional extinctions. But finding those genes is a grand scientific challenge. The National Science Foundation is funding a diverse team of researchers from US Geological Survey, Smithsonian Institute, and academia to sample DNA from bird populations across the Hawaiian archepelago, genotype sampled individuals, and identify genes associated with increased survival.
Many factors including habitat destruction, invasive plants, non-native predators and competitors, and introduced diseases have decimated the diverse, endemic native forest bird community of Hawai‘i. In particular, avian malaria (Plasmodium relictum), which is transmitted by the introduced Southern House Mosquito (Culex quinquefasciatus), has caused dramatic declines and extinctions in many native...

Many of Hawai‘i’s forest birds have shown significant declines in the past 200 years, with many currently listed as endangered species. Multiple threats have been identified as contributing to declines, including disease, invasive species, habitat loss, and decreased survivorship and productivity caused by introduced predators. Demographic and ecological studies are needed to determine how...
