A multi-disciplinary evaluation of the hybrid anemonefish Amphiprion leucokranos: behaviour shaping evolutionary outcomes of hybridization.
Hybridization is an important source of genetic variation within the marine environment. The highly diverse nature of coral reef assemblages offers many opportunities to broaden our understanding of ecological and evolutionary implications associated with current and historical gene exchange between naturally hybridizing species. The project aims to evaluate the ecological and evolutionary implications of reef fish hybridization with the application of genetic techniques to provide high resolution inference of genetic structure within and among taxa. The broad objective of the project is to evaluate localised differences between regions across the narrow hybrid zone between two anemonefish species, and a confirmed hybrid. This project will use ecological and morphological techniques, as well as phylogenetic and population genetic analyses, to address this question, as well as how populations outside the hybrid zone compare to those within, how species are changing through time and whether an advantage or disadvantage exists for hybrids within mixed species groups with strong social structuring behaviour.

The most extensive reef survey of the Coral Sea Marine Park ever undertaken will continue this week as scientists from ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral C
Scientists have used modern genetic techniques to prove age-old assumptions about what sizes of fish to leave in the sea to preserve the future of local fisheries. “We’ve known for decades that
Scientists say outdated assumptions around gender continue to hinder effective and fair policymaking and action for climate mitigation and adaptation. Lead author of a new study, Dr Jacqueline Lau
For the first time, scientists have assessed how many corals there are in the Pacific Ocean—and evaluated their risk of extinction. While the answer to “how many coral species are there?” is
Abstract: The fate of fish larvae during the pelagic phase has profound effects on replenishment of marine populations that are critical for human and ecosystem health. The survival and transport of l
Abstract: Neonate sharks experience high predation during early ontogeny. For this reason, predator avoidance is the major driver of shallow-water habitat use in neonate sharks. When a predator encoun
Abstract: Humans have been harvesting predators and other creatures from the global oceans for millennia. More recently, conservation measures, such as marine reserves, have been established to restor

Abstract: We frequently hear about demise and decline in fisheries systems. This narrative can inadvertently shift thefocus of research and funding away from the opportunities and benefits avail
Abstract: Multiple habitats in a tropical seascape are increasingly recognized as interconnected to one another. Mangroves, seagrass beds, and macroaglal beds are important components of a tropical se
Abstract: Current conservation goals for reef-building corals under climate change involve boosting desirable traits like heat tolerance and fast growth in natural and restored coral populations. This
