The emergence of infectious diseases is often associated with changes to host–pathogen ecology, and wildfires are known to profoundly modify the ecology of terrestrial and freshwater ecosystems. Nevertheless, few studies have employed manipulative experiments to quantify the effects of fire on infections across parasite species. In a mark–recapture study, prescribed burns did not significantly affect the densities of Cuban tre...

What happens when two emergent diseases infect the same host? In a From the Cover article in this issue of Molecular Ecology, McDonald et al. (2020) compare transcriptomic responses to co‐infection by the two chytrid fungi in the skin, liver and spleen of Eastern newts ( Notophthalmus viridescens ). Novel molecular tools, such as high‐throughput DNA sequencing for genome discovery and transcriptomics, have revolutionized our u...
