Climate‐Driven Increase in Transmission of a Wildlife Malaria Parasite Over the Last Quarter Century [PDF]

Global change biology.
Climate warming is shaping ecosystems in several ways, and this includes changes in the dynamics of wildlife disease transmission. Over 26 years, avian malaria parasites have become much more common in a population of blue tits, small songbirds that we surveyed in southern Sweden.
