Dr Peter Caley, of CSIRO, will explore which of the numerous putative drivers are consistent with the observations of the decline of the famous Bogong moth.

Bogong moth populations are in decline. Following a big decrease in numbers after European colonisation expanded across their breeding range, a subsequent decline from about 1980 has been followed by a dramatic drought-induced crash from 2017--2019. It appears that something has fundamentally changed in the environment, such that it no longer supports the abundance of bogong moths that it once did. Caughley's declining population paradigm provides a systematic, scientific approach to diagnosing the proximal factor(s) driving the decline, and hence knowledge for reversing such declines. This talk explores which of the numerous putative drivers are consistent with the observations.

Dr Peter Caley is a research scientist with CSIRO Data61. He has a background in applying quantitative methods to address contemporary problems in the environmental, agricultural and health sciences. He has an ongoing research interest in the dynamics of animal populations, with recent examples including inferring trends in the abundance of waterbird populations, flying foxes, and bogong moths.
