Emerging infectious diseases in wildlife species caused by pathogenic fungi are of growing concern, yet crucial knowledge gaps remain for diseases with potentially large impacts. For example, there is detailed knowledge about host pathology and mechanisms underlying response for chytridiomycosis in amphibians and white‐nose syndrome in bats, but such information is lacking for other more recently described fungal infections.

Fitness of hybrids between genetically modified (GM) crops and wild relatives influences the likelihood of ecological harm. We measured fitness components in spontaneous (non‐GM) rapeseed × Brassica rapa hybrids in natural populations. The F 1 hybrids yielded 46.9% seed output of B. rapa , were 16.9% as effective as males on B. rapa and exhibited increased self‐pollination. Assuming 100% GM rapeseed cultivation, we conservativ...
