“…Given that populations of L. fallax may have a high prevalence of the amphibian chytrid fungus ( Batrachochytrium dendrobatidis ) and not suffer population declines as a result (Kriger and Hero 2007), it is possible that introduced populations of L. fallax are acting as disease amplifiers or reservoir hosts (e.g. Rivera et al . 2019).…”

An increasing number of species are establishing populations outside of their native ranges, often with negative ecological and economic impacts. The detection and surveillance of invasive species presents a huge logistical challenge, given the large spatial regions in which new populations can appear. However, data collected through citizen science projects are increasingly recognised as a valuable source for detection and monitoring of invasive species. We use data from a national citizen science project, FrogID, to quantify the spread of the eastern dwarf tree frog (Litoria fallax) outside its historical native range in Australia. Of 48 012 records of L. fallax in the FrogID database, 485 were located far outside the historical native range of the species. L. fallax has established geographically large populations hundreds of kilometres away from its native range, and these appear to be spreading in extent over time. These populations have resulted in novel species co-occurrences, with L. fallax now co-occurring with at least two frog species not present in their native range. Although the impacts of the invasive populations of L. fallax remain unknown, our work highlights the value in leveraging citizen science projects to detect and monitor native species that can become invasive far outside their historical range.

Ranaviruses are globally distributed pathogens in amphibian, fish, and reptile communities that appear to be emerging. Cases of ranavirus infection or disease have been confirmed in at least 177 amphibian species (25 families), 49 fish species (25 families), and 37 reptile species (17 families). Transmission of individual strains between animal classes has been documented. While ranaviruses are frequently associated with mass die-offs, host susceptibility differs among species, with some species harboring subclinical infections and likely serving as reservoirs for the virus and other highly susceptible species amplifying the virus. Currently, there are seven recognized species of ranavirus, with stark differences in pathogenicity between strains and hosts. Several strains among these species have been named, and changes in taxonomy in this genus can lead to some confusion. Frog virus 3 is the best studied species of the genus Ranavirus and appears to be the most globally distributed species, with viruses of this species infecting ectothermic vertebrates across three vertebrate classes. International commerce involving infected ectothermic vertebrates undoubtedly has contributed to the global distribution, diversity, and emergence of ranaviruses. Herein, we describe the global distribution of ranaviruses in amphibians, fish, and reptiles, host range of the different Ranavirus species, the implications of interclass transmission, and the impact of trade on ranavirus distribution. The Global Ranavirus Reporting System (GRRS), which documents global detections of ranaviruses, is also presented.
