Can hot temperatures limit disease transmission? A test of mechanisms in a zooplankton–fungus system

Thermal ecology theory predicts that transmission of infectious diseases should respond unimodally to temperature, that is be maximized at intermediate temperatures and constrained at extreme low and high temperatures. However, empirical evidence linking hot temperatures to decreased transmission in nature remains limited. We tested the hypothesis that hot temperatures constrain transmission in a zooplankton–fungus ( Daphnia...
