Inconsistent dilution: experimental but not field evidence for a dilution effect in Daphnia-bacteria interactions.

Abstract excerpt

The dilution effect hypothesis, which suggests greater host biodiversity can reduce infectious disease transmission, occurs in many systems but is not universal. Most studies only investigate the dilution of a single parasite in a community, but many host communities have multiple parasites circulating. We studied a zooplankton host community with prior support for a dilution effect in laboratory- and field-based...
