Dr Leila Brook B.Sc. (Hons.), PhD

Read More

Leila has recently joined Ecology Australia after working in government (DSE / DELWP) on ecological policy, particularly for threatened taxa and communities.

Leila’s PhD in Tropical Ecology investigated the ecological interactions between dingoes and feral cats in northern Australia. She used remote camera surveys and high-frequency telemetry data to explore both broad-scale trends in abundance, habitat use and behaviour and fine-scale space use patterns.  She has a strong interest in the influence of species interactions on ecosystem function and dynamics, especially their potential to provide a buffer against environmental change or threatening processes.

She has developed a broad range of scientific and analytical skills through her research and gained a good understanding of many broadly distributed vertebrates such as macropods, introduced predators, rodents and birds.
