Publicly released:
Avian malaria is rising in NZ, threatening vulnerable native bird species. A modelling study from an NZ-Canadian team used data from 18 South Island sites to reveal that human-driven changes to landscape may lead to more avian malaria infections in the studied non-native bird species like blackbirds and thrushes, which are known to be hosts for malaria parasites. This potentially ups the risk of local infection for other species like native birds. The authors also predict warmer and wetter places will have a higher risk of avian malaria spread, and say landscape restoration is vital to mitigate the impact of infectious diseases on wild ecosystems.
