TL;DR: It is shown that the widely used herbicide, atrazine, was the best predictor of the abundance of larval trematodes in the declining northern leopard frog Rana pipiens, and analysis of field data supported a causal mechanism whereby both agrochemicals increase exposure and susceptibility to larval Trematodes by augmenting snail intermediate hosts and suppressing amphibian immunity.

TL;DR: Exposures of metamorphic frogs to cercariae revealed that these individuals can become infected with echinostomes, and highlighted the host stage–dependent dynamics of tadpole–echinostome interactions.

TL;DR: A key role for hatch-year birds is indicated in the amplification of epizootic transmission of WNV, and in increasing human infection risk by facilitating local viral amplification.

TL;DR: It is shown that the diversity of predators that consume parasites was the best negative predictor of infections in frogs, suggesting that predation on parasites can be an important mechanism of disease reduction.

TL;DR: The effects of timing of infection on tadpole survival and limb development are examined and it is suggested that the timing of R. ondatrae infection in relation to the stage structure of tadpole populations in the wild is an im- portant determinant of the degree to which populations are affected.
