Abstract: Species in the fungal genus Batrachochytrium are responsible for severe declines in the populations of hibians globally. The sources of these pathogens have been uncertain. O'Hanlon et al. used genomics on a panel of more than 200 isolates to trace the source of the frog pathogen B. dendrobatidis to a hyper erse hotspot in the Korean peninsula (see the Perspective by Lips). Over the past century, the trade in hibian species has accelerated, and now all lineages of B. dendrobatidis occur in traded hibians the fungus has become ubiquitous and is ersifying rapidly.

Abstract: Parasitic chytrid fungi have emerged as a significant threat to hibian species worldwide, necessitating the development of techniques to isolate these pathogens into culture for research purposes. However, early methods of isolating chytrids from their hosts relied on killing hibians. We modified a pre-existing protocol for isolating chytrids from infected animals to use toe clips and biopsies from toe webbing rather than euthanizing hosts, and distributed the protocol to researchers as part of the Bio ERsA project RACE here called the RML protocol. In tandem, we developed a lethal procedure for isolating chytrids from tadpole mouthparts. Reviewing a database of use a decade after their inception, we find that these methods have been applied across 5 continents, 23 countries and in 62 hibian species. Isolation of chytrids by the non-lethal RML protocol occured in 18% of attempts with 207 fungal isolates and three species of chytrid being recovered. Isolation of chytrids from tadpoles occured in 43% of attempts with 334 fungal isolates of one species ( Batrachochytrium dendrobatidis ) being recovered. Together, these methods have resulted in a significant reduction and refinement of our use of threatened hibian species and have improved our ability to work with this group of emerging pathogens.

Abstract: Lambert et al . question our retrospective and holistic epidemiological assessment of the role of chytridiomycosis in hibian declines. Their alternative assessment is narrow and provides an incomplete evaluation of evidence. Adopting this approach limits understanding of infectious disease impacts and h ers conservation efforts. We reaffirm that our study provides unambiguous evidence that chytridiomycosis has affected at least 501 hibian species.

Abstract: Rapid spread of disease is a hazard in our interconnected world. The chytrid fungus Batrachochytrium dendrobatidis was identified in hibian populations about 20 years ago and has caused death and species extinction at a global scale. Scheele et al. found that the fungus has caused declines in hibian populations everywhere except at its origin in Asia (see the Perspective by Greenberg and Palen). A majority of species and populations are still experiencing decline, but there is evidence of limited recovery in some species. The analysis also suggests some conditions that predict resilience.
