Abstract: | Background A central hypothesis in the evolutionary ecology of parasitism is that trade-offs exist between resistance to parasites and
other fitness components such as fecundity, growth, survival, and predator avoidance, or resistance to other parasites. These
trade-offs are called costs of resistance. These costs fall into two broad categories: constitutive costs of resistance, which
arise from a negative genetic covariance between immunity and other fitness-related traits, and inducible costs of resistance,
which are the physiological costs incurred by hosts when mounting an immune response. We sought to study inducible costs in
depth using the crustacean Daphnia magna and its bacterial parasite Pasteuria ramosa. |
