Celebrating #WorldEnvironmentDay‌2024 with #hunterenvironmentalinstitute and @UON_research ray guru Molly Grew. Awesome non-invasive techniques for measuring the contribution of rays to estuarine ecosystems.

Check out our new article in The @ConversationEDU talking about a new way to detect the amphibian fungal disease in Asia. Was fantastic to collaborate with such good people on such an important project. @SreedharanGaya3 @Science_Academy @ConservationUon theconversation.com/the-worl…

The chytrid fungal disease has been decimating frog populations worldwide for decades, and research progress has been slow. A new method for detecting the disease could help change its course.

I got so excited when google photos shared a memory with me called 'Underwater Adventures'. But all it served to do was remind me that perhaps I need a holiday 😜 #frogs #conservation #tiredscience photos.app.goo.gl/xvhv88rvFC…

It's a frog's life - disease, dispersal and diversity - Small population size results in low genetic diversity driving a high risk of local extinction. The Blue Mountains population of the endangered Littlejohn's tree frog requires urgent on ground conservation actions.

Our latest research highlights the urgent need for conservation management of the endangered Littlejohn's Tree Frog. Genetic data reveals 5 distinct clusters, small populations and loss of genetic diveristy. #BioDiversityCrisis #conservation #frogs rdcu.be/da5Ub

I am thrilled to have been awarded second place in University of Newcastle's Three Minute Thesis competition. Such tough and diverse competition. Congrats to all finalists and particularly Katie who will now represent UON at the Asia-Pacific finals.

Not so many gambusia in our hunt in the rain tonight, just the usual stolen tech rising from the murky depths of Kooragang #ilovekooragang #conservationbiology #kooragangcleanup @Uni_Newcastle @ConservationUon 🐸
