Increasing temperatures accentuate negative fitness consequences of a marine parasite
Abstract Infectious diseases are key drivers of wildlife populations and agriculture production, but whether and how climate change will influence disease impacts remains controversial. One of the critical knowledge gaps that prevents resolution of this controversy is a lack of high-quality experime...

Abstract Infectious diseases are key drivers of wildlife populations and agriculture production, but whether and how climate change will influence disease impacts remains controversial. One of the critical knowledge gaps that prevents resolution of this controversy is a lack of high-quality experimental data, especially in marine systems of significant ecological and economic consequence. Here, we performed a manipulative experiment in which we tested the temperature-dependent effects on Atlantic salmon ( Salmo salar ) of sea lice ( Lepeophtheirus salmonis )—a parasite that can depress the productivity of wild-salmon populations and the profits of the salmon-farming industry.
