For most people the term “ancient DNA” might conjur up images of Jurassic Park, where DNA extracted from a mosquito preserved in amber was used to re-create long extinct dinosaurs.

Adelaide is losing 75,000 trees a year. Tree-removal laws must be tightened if we want our cities to be liveable and green

Large areas of concrete and asphalt absorb and radiate heat, creating an “urban heat island effect”. It puts cities at risk of overheating as they are several degrees warmer than surrounding areas.
Heat stress from ocean warming harms octopus vision

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.

Exploring ancient DNA for environmental insights
![Exploring ancient DNA for environmental insights](/environment/sites/default/files/styles/ua_landscape/public/media/images/2024-05/image-1000x700.jpg?h=c4dd2c7b&itok=sysIBgL4)
Ancient environmental DNA (aeDNA) has revolutionised the study of ancient environments and the evolution of living things. It helps researchers unlock secrets found in sediments, ice, and water and has transformed our understanding of past biodiversity across different timescales, from decades to thousands of years ago. The Environment Institute is privileged to support the training of highly specialised experts in these cutting-edge techniques.

Wildlife in our homes: Australian reptiles in the global exotic pet market
![A shingleback skink](/environment/sites/default/files/styles/ua_landscape/public/media/images/2024-05/shingleback.jpg?h=c4dd2c7b&itok=a_NEcUDA)
On March 3rd we celebrate World Wildlife Day, and the theme for 2024 is "Connecting People and Planet: Exploring Digital Innovation in Wildlife Conservation." We are thrilled to feature the research of our guest blogger, Sebastian Chekunov, a PhD candidate from Dr. Phill Cassey's Invasion Ecology research group. Dr Cassey is an ARC Industry Laureate Fellow, Combatting Wildlife Crime and Preventing Environmental Harm.
