Maria completed her Ph.D. in 2006 on neutral theory and biodiversity patterns of reef corals, under the supervision of Sean Connolly and Terry Hughes. She moved to Scotland to take up her first postdoctoral fellowship in Anne Magurran’s lab at the University of St Andrews. Maria came back to Australia to join the ARC CoE of Coral Reef Studies last February.
Species abundance distributions summarize the patterns of species rarity and commonness in ecological communities, and are the biodiversity pattern most often used to test biodiversity models. However, the abundances of rare species require large samples to be confidently estimated. In this seminar I will present the species abundance distribution for a sample of >40,000 coral colonies from a single bay in Lizard Island. This exceeds existing samples of coral assemblages by over an order of magnitude. Although species abundance distributions are widely accepted to follow a lognormal distribution, these data have a multimodal distribution, and are best fitted by a mixture of three lognormal distributions. Several types of heterogeneities within the community are explored, but only differences among species spatial distributions are linked to multimodality.
Scientists say outdated assumptions around gender continue to hinder effective and fair policymaking and action for climate mitigation and adaptation.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
Scientists have discovered a never-before-seen biodiversity pattern of coral reef fishes that suggests some fishes might be exceptionally vulnerable to environmental change. A new study shows plank
Scientists say stable seafood consumption amongst the world’s poorer coastal communities is linked to how local habitat characteristics influence fishing at different times of the year. In the co
Abstract: The vast majority of reef fishes have a life history consisting of a pelagic larval phase of typically 20 to 60 days, followed by larval settlement where they remain through their juvenile a
Abstract: Social networks have been and remain important across the Pacific Islands, and beyond, for building and maintaining social-ecological resilience. However, there is little quantitative infor
Abstract: The global conservation community is comprised of a range of organisations, processes, and professionals. Given the diversity of these actors, and the complexity of the systems that conser
Abstract: Seasons create a rhythm in nature and, by extension, in the lives of people who depend directly on natural resources. However, our understanding of how seasons affect the ways that people
Abstract: Oceanic shark populations have declined 77% over the past 60 years as a result of overexploitation in fisheries. However, sustainable shark management is limited to a few developed nations
Abstract: Vertigo3 is a new class of small, fast and agile ‘true-flight’ underwater glider, purposely designed for robotic, artificial intelligence-assisted broadscale marine surveys, and capable
Abstract: Recurrent marine heat waves are leading to widespread coral bleaching, transforming the structure and function of tropical coral reefs. Past bleaching events have highlighted large variatio
Abstract: Shallow-water tropical seascapes typically include a range of habitat types such as coral reefs, mangroves, macroalgal and seagrass beds. These habitats can occur in close proximity and are
