Distribution of native birds and non-native mosquitoes that transmit avian malaria relative to temperature and elevation in Hawai‘i

Distribution of native birds and non-native mosquitoes that transmit avian malaria relative to temperature and elevation in Hawai‘i

Temperature and elevation affect the distribution and intensity of avian malaria in Hawai‘i. Climate change is aiding the rapid movement of disease into disease-free forests. At low elevations, mosquitoes breed year-round, and disease transmission is too intense for most native bird species to persist.

A major advancement in the use of radio telemetry has been the development of automated radio tracking systems (ARTS) which allow animal movements to be tracked continuously. A new ARTS approach is the use of a network of simple radio receivers (nodes) that collect radio signal strength (RSS) values from animal-borne radio transmitters.

Geneticist, Kylle Roy, extracts DNA from samples to detect Ceratocystis, a fungal pathogen that causes Rapid Ohia Death. Samples have been acquired using aerial spore traps, by collecting wood shavings from ohia trees, or by collecting frass (excrement) of wood-boring beetles.

A trap designed for collecting airborne particulates deployed on the Hāmākua Coast of the island of Hawai‘i. The traps appear to be an effective method for monitoring airborne fungal spores as hundreds of fungal taxa were identified from a handful of samples screened by second generation sequencing.
