We review our ecological understanding of wildlife infectious diseases from the individual
host to the ecosystem scale, highlighting where conceptual thinking lacks verification …

Parasite resistance mechanisms can be costly to maintain. We would therefore predict that
organisms should invest in resistance only when it is likely to be required. Insects that show …

Pairwise invadability analysis is used to examine the evolutionary dynamics of host
resistance to microparasitic infection. A continuum of strains of the host differs in …

Theory suggests that the current rapid increase in connectivity and consequential changes
in the structure of human, agricultural, and wildlife populations may select for parasite strains …

1. We studied the effect of parasitism on snowshoe hare (Lepus americanus) survival
through a field experiment that reduced natural burdens of sublethal nematodes in a free …

Parasite resistant hosts may avoid becoming infected, recover more quickly after infection or
survive longer once infected. A model is constructed to examine the evolution of costly host …

Many viral, bacterial and protozoan parasites of invertebrates first propagate inside their
host without releasing any transmission stages and then kill their host to release all …

The prevalence of pathogens in wild populations has often been estimated by the
appearance of overt symptoms in the host, and this is typically used as the sole gauge of the …

Generation cycles are population cycles with a period of roughly one generation. They have
been observed in tropical pest populations and in laboratory populations. Theory suggests …

1. Baculoviruses are often highly pathogenic to their insect hosts, but theoretical studies
have shown that sublethal infections may also play an important role in host population …
