The Great Barrier Reef has lost half its corals
A new study of the Great Barrier Reef shows populations of its small, medium and large corals have all declined in the past three decades. Lead author Dr Andy Dietzel, from the ARC Centre of Excell

Abstract: Biodiversity plays a critical role in the resilience of natural systems. Although there is a directed effort towards understanding current threats to biodiversity (e.g. climate change), very little research examines the origins of such biodiversity and how it is maintained. I address these fundamental questions by summarising a multi-disciplinary genetic survey of Red Sea and Arabian Sea marine fauna, with a particular focus on endemic and widespread reef fish. This work flows into some of my more recent trials using next-generation sequencing technology to help audit marine biodiversity via degraded DNA sources, thus improving best-practice management for coral reef ecosystems.
Biography: Joseph is an Early Career Postdoctoral Fellow (ECRF) at Curtin University in Western Australia. He holds a Ph.D. from McGill University in Montreal, Canada, completed an NSERC postdoctoral fellowship at the Hawai’i Institute of Marine Biology (HIMB), USA, and recently completed a postdoctoral position at the King Abdullah University of Science and Technology (KAUST). His research is directed towards understanding the origins of species-level biodiversity and how it is maintained. He is interested in the integration of classical and novel molecular approaches to resolve patterns of genetic variation within and between marine populations (or species), identifying historical and contemporary factors that influence separation of such populations (or species), incorporating phylogeographic findings into the design of marine protected areas, and tracking evolutionary responses in natural (or experimental) populations.

Scientists have found that as the world undergoes profound environmental change, identifying and protecting ‘novel’ communities of species can help prevent extinctions within vulnerable ecosystems
Scientists say a ‘portfolio’ of protected areas within marine parks such as the Great Barrier Reef can help secure sustainable fish populations. Dr Hugo Harrison from the ARC Centre of Excellen
Scientists have developed a new genetic tool that can help them better understand and ultimately work to save coral reefs. “Surprisingly, we still don’t know how many coral species live on the

Abstract: When abundant, seabirds feeding in the open ocean transport large quantities of nutrients onto islands, enhancing the productivity of island fauna and flora. These nutrients can leach int

Abstract: Globally, coral reefs are under threat. Unfortunately, the rate of ecosystem degradation often surpasses the rate of generation of knowledge required to support management. Despite the consi
