Ecology and management of wildlife pandemics
Infectious diseases can have catastrophic impacts on biodiversity, causing population declines and extinctions of wild species and increasing vulnerability of populations to existing pressures. Many of the risks that wild species face due to infectious diseases are enhanced or arise due to human activities, including habitat degradation and fragmentation, climate change, global trade, and local activities that can facilitate spread. These factors also commonly contribute to infectious disease threats to humans, many of which originate in wildlife as zoonoses. Pandemics of every kind thus represent a globally significant threat to health security.
Chytridiomycosis and other emerging fungal infections

Amphibian chytridiomycosis has been described as the most significant disease of vertebrates in recorded history, causing widespread extinctions and catastrophic population declines across the globe. The emergence of the fungal pathogen causing this disease (Batrachochytrium dendrobatidis) has been driven by the extensive trade in amphibian species, which allowed opportunities for pathogen mixing and the global spread of a virulent pandemic strain. Distribution and impacts of the disease are mediated by a huge range of factors, including life-history and ecological traits of affected species and numerous environmental factors (e.g., climate and temperature extremes and variability).
We are studying numerous aspects of the ecology and management of chytridiomycosis, including the risks associated with the wildlife trade and biosecurity strategies, risk factor analyses of infection in wild and laboratory settings, understanding and dating the origins of the pandemic strain, and developing global collaborative networks to develop research on this, and other, emerging pathogenic fungi in wildlife, including chytridiomycosis in salamanders (caused by a related chytrid species, B. salamandrivorans) and white-nose syndrome in bats (also caused by a fungus, Pseudogymnoascus destructans). We are also widely engaged with policy makers in order to advise on national and international strategies to mitigate the threat of novel infectious diseases in wildlife.
