Experts say the fish kill might have been caused by a combination of extreme heat and stormwater runoff lowering oxygen levels in the seawater close to shore.
Wildfires are becoming larger and more frequent in forests under climate change, with corresponding increases in area burnt recently and at high-severity. Australian fire regimes are changing rapidly, but the implications for fauna are poorly understood. The first of two overarching aims of this research was to increase understanding of the mechanisms and processes that underpin avian responses to fire regimes in montane dry sclerophyll forests of south-eastern Australia. The second was to investigate the implications of altered fire regimes for birds through evaluation of their responses where fire activity is currently high.
Due to its deep modification of biotic and abiotic elements compared to natural habitats, the urban environment, which is extending every year with human population expansion, causes problems for bird survival.
