Parasite prevalence increases with temperature in an avian metapopulation in northern Norway
Abstract Climate and weather conditions may have substantial effects on the ecology of both parasites and hosts in natural populations. The strength and shape of the effects of weather on parasites and hosts are likely to change as global warming affects local climate. These changes may in turn alte...
