Abstract: Recent losses of worldwide biodiversity include population declines and extinctions in many amphibian populations. Many factors, including pathogens, are contributing to amphibian population declines. One pathogen, a water mould of the genus Saprolegnia, causes mortality in early life stages of amphibians and may contribute to the declines of specific amphibian populations. Most of our knowledge of how Saprolegnia affects amphibians comes from studies of embryos. The effects of Saprolegnia on post-metamorphic amphibians are poorly known. Therefore, in the laboratory, we investigated the susceptibility of newly-metamorphosed juvenile amphibians to Saprolegnia in four frog species: Bufo boreas (western toad), Pseudacris regilla (Pacific treefrog), Rana aurora (red-legged frog) and R. cascadae (Cascades frog). We found that juvenile R. cascadae exposed to Saprolegnia had greater rates of mortality than unexposed controls. In the other species, survival was also lower in the Saprolegnia treatments compared with controls but these differences were not statistically significant. Combined effects of Saprolegnia in both embryonic and juvenile stages may make the populations of R. cascadae especially vulnerable.

IMPORTANT NOTE - JUNE 2020

Please note that as from Volume 31 Number 1 (January 2021) on, the Herpetological Journal will be available as an online publication only - the last print edition will be Volume 30 Number 4.   

Aligning with this change, it is now no longer possible to purchase a subscription that includes a print copy of the HJ.  All members who have existing HJ print subscriptions that remain active as at end June 2020 will receive the full four 2020 print editions.  New subscribers or renewals after this time will only have option to subscribe to the online only subscription package.  Subscription pricing has been amended to reflect the content changes.
