Can predators stabilize host–parasite interactions? Changes in aquatic predator identity alter amphibian responses and parasite abundance across life stages

open access: yesEcology and Evolution, 2022
The role of parasites can change depending on the food web community. Predators, for instance, can amplify or dilute parasite effects on their hosts.

Context-dependent effects of ranaviral infection on northern leopard frog life history traits.

open access: yesPLoS ONE, 2010
Pathogens have important effects on host life-history traits, but the magnitude of these effects is often strongly context-dependent. The outcome of an interaction between a host and an infectious agent is often associated with the level of stress ...

Physiological control of water exchange in anurans

open access: yesEcology and Evolution, 2022
Research on water exchange in frogs has historically assumed that blood osmotic potential drives water exchange between a frog and its environment, but here we show that the “seat patch” (the primary site of water exchange in many anurans), or other ...

Of Frogs & Rhetoric: The Atrazine Wars [PDF]

open access: yes, 2015
In a scientific dispute over the effects of atrazine on amphibians, chemical industry–funded and publically funded scientists present stunningly contrasting constructions of atrazine\u27s environmental concentrations, persistence, and potential to harm ...

Up and away: ontogenic transference as a pathway for aerial dispersal of microplastics [PDF]

open access: yes, 2018
Microplastics (MPs) are ubiquitous pollutants found in marine, freshwater and terrestrial ecosystems. With so many MPs in aquatic systems it is inevitable that they will be ingested by aquatic organisms, and be transferred up through the food chain ...
