Echolocation evolved multiple times in bats over millions of year. Yet the earliest bat ancestors probably didn't have this skill — or if they did, it was likely very primitive.
A world-first framework will help identify the ecosystems that are most critical for biodiversity conservation, research, management and human wellbeing.
The native species has reached numbers that are contributing to drier soil and less vegetation – and may be more damaging to conservation areas than rabbits.
A UNSW study shows airway bacteria can indicate the health of dolphins and whales – a finding that could benefit endangered species like the northern right and blue whales.
Engineers and scientists at UNSW Sydney have come up with an ingenious way to get fish past dam walls, weirs and other barriers blocking their migration in Australian rivers.
The tube fishway allows fish to glide past dam walls, weirs and other river barriers, with the potential to revitalise Australia’s ailing freshwater fish stocks.
