Predator Community

There are few published studies of the population ecology of the larvae of Australian native anurans. In this study we report on the population dynamics of the larvae of the Australian frog Crinia signifera at a study site near Bridgewater in the Adelaide Hills, South Australia. The predator community was also monitored to provide an indication of the importance of predation in influencing the population dynamics of C. signifera larvae. Pool drying meant larvae failed to metamorphose from temporary pools in all years of the study. In a permanent pond, mortality was high and variable, with an average of 10% survival over the three years of the study. There was a complete failure to recruit to the terrestrial phase in one year. Predation pressure was thought to be the most important source of mortality in the permanent pond, although predator numbers varied considerably between and within years. When combined with information on the population ecology of the embryonic (Williamson and Bull 1994) and terrestrial (Williamson and Bull 1996) stages, the data suggest that the aquatic phase is the key phase in the population dynamics of this species.

Amphibians are declining around the world and infectious diseases are thought to play a key role in these declines, along with habitat destruction and other environmental factors.  Since the late 1900s, several emerging infections have been identified in amphibians. The chytrids, of which there are two known to affect amphibians, Batrachochytrium dendtrobatids, and B. salamandrivorans; and ranaviruses are perhaps the most well-known and studied. There are also other, lesser known and studied pathogenic agents such as Perkinsea spp. and herpesviruses; that have emerged in approximately the same timeline, which may also be contributing to amphibian population dynamics. In this piece we examine the progress that has been made over the past decade in understanding ‘The Big Three’ and specifically how the emergence of B. salamandrivorans has brought together much of the amphibian disease world in the last half of the 2010s.
