Aaron Davis’ research broadly focuses on catchment water quality in northern Australia, particularly the role of anthropogenic (human) stressors in aquatic communities. One of his key research interests is identifying progressive agricultural practices that offer industry improvements from a natural resource management perspective, while also ensuring the long-term social and economic viability of farming enterprises. Aaron is also interested in better quantifying the temporal and spatial extent of water quality contamination in coastal freshwater and estuarine wetlands, particularly in regard to chronic, sub-lethal exposure to pollutants. Other research interests include landscape ecology in relation to wetland connectivity, and identifying primary production sources for aquatic communities and relationships to flow regime (for instance, dietary and isotopic ecology). Aaron’s research interests also span fish ecology, particularly size-related trophic ecology, and the evolutionary processes influencing the present-day Australasian fish fauna. This includes the biogeographic, phylogenetic and paleoecological drivers that have shaped the unique contemporary fish assemblage structure seen in Australian freshwaters.

Abbi Scott moved to Australia in 2016 to pursue a passion for seagrass ecology after working on seagrasses, rocky shore ecology and citizen science projects in the UK. Abbi completed her PhD with the TropWATER seagrass ecology team in 2021, with her research examining how herbivores structure seagrass meadows on the Great Barrier Reef and how this could affect the delivery of ecosystem services by seagrasses. The focus was on the herbivore community as a whole, from large herbivores such as dugongs and turtles to small mesograzers, to quantify their impact on meadow structure. Understanding the role of plant-herbivore interactions in structuring seagrass meadows and modifying seagrass ecosystem service delivery is key to managing and conserving both seagrass meadows and herbivore populations in the future. Abbi currently works on research in seagrass herbivory, monitoring and restoration and coordinates the Cairns Port Douglas Reef Hub. Abbi is also an enthusiastic science communicator who has made regular contributions to illuminate the wonders of marine life and science on ABC radio. She also shares her knowledge via seminars targeted at various audiences, and through her blog.

Richard was employed at JCU as Senior Tutor in Zoology in 1974, eventually becoming Professor in 1999. He was successful in his 1988 funding application to the federal government to establish the Australian Centre for Tropical Freshwater Research (ACTFR, now TropWATER) and became its Deputy Director, moving to Director in the mid-90s. He was appointed as Head of the new School of Tropical Biology in 1999 and subsequently relinquished the directorship of the ACTFR. During this time, he continued to teach, supervise postgraduate students and undertake research, for which he had continuous funding from several sources. Richard initially investigated the effects of river pollution by sugar mills, followed by projects associated with the sugar industry and Cooperative Research Centres for Rainforest Management and the Great Barrier Reef. For the rainforest CRC he investigated the ecology of pristine tropical streams and continued that work beyond retirement in an international programme on stream ecology. He led the original joint CRC Catchment to Reef programme, and he worked for several years on the ecology of the Burdekin River. Richard has authored at least 70 technical reports and over 160 refereed journal papers and book chapters. He supervised more than 70 postgraduate students. He continues to collaborate with TropWATER staff and others, and to write up his and his students’ research results.

Rob has a Bachelor of Science in zoology, an Honours degree (first class) in entomology, and a PhD in fisheries from the University of Queensland. He has worked as an entomologist, a fisheries scientist, a fisheries manager in the Torres Strait, an environment and regional manager for the Queensland government, and as a seagrass scientist and research administrator. Rob has a history of promoting seagrass and coastal management research in the Indo-Pacific region and around the world and was the founding secretary of the World Seagrass Association. Some of Rob’s recent work has seen him study the connectivity among seagrass meadows and how this may influence management approaches. He has also been part of a team that has recompiled and revalidated Australian seagrass data extending back to the early 1980s with the aim to provide a publically available and reliable data set. His recent research and environment management focus has been to engage with northern Australian Traditional Owner groups in collaboration with seagrass and dugong expert colleagues from James Cook University and Charles Darwin University. This approach responds to concerns about threats and reduced resilience in the coastal environment. It addresses knowledge gaps about dugongs and seagrasses that are critical to Traditional Owners’ cultural identity and traditional values.

Severine Choukroun is a physical oceanographer and biophysical modeller with a background in marine science. Severine has developped hydrodynamic models models for understanding and predicting ecological processes – like how marine life moves in ocean currents – and understanding how physical and biological processes influence marine population connectivity and persistence. She has significant experience in conducting observational and modelling research on coastal and shelf dynamics, coupled with biophysical modelling that integrates complex early life behaviour. Severine’s recent activities include work with crown-of-thorns starfish (COTS), including a project with CSIRO to develop information infrastructure to better share modelled data between stakeholders involved in COTS control. This will improve data-sharing reliability and efficiency, while aligning with the broader infrastructures already being created through other programs. Severine is also studying patterns of COTS outbreaks on the Great Barrier Reef by tracking larval spread via ocean currents. Understanding, measuring and predicting how larvae are dispersed is vital to both modelling COTS outbreaks on the GBR and controlling those outbreaks effectively.

Shelley (Michelle) Templeman’s research is broadly focused on understanding the impacts of pollutants and contaminants in tropical aquatic ecosystems, as well as developing more suitable ecological monitoring tools to measure and mitigate pollutant impacts. A childhood spent on cattle properties in central Australia may seem like an unlikely foundation for an aquatic scientist, however this experience provided Shelley with some early insights into the important interactions and impacts between humans and the environment. Since leaving school she has completed a range of undergraduate and postgraduate qualifications across Australia, mostly while performing several scientific roles in northern Australia, Indonesia and Antarctica. Shelley’s studies culminated in a PhD at James Cook University in 2012, investigating the bioindicator potential of jellyfishes to metal pollution. Her more recent research is focused on macroinvertebrate taxonomy and biological monitoring at Kakadu National Park in the Northern Territory. Also, she is working with a north Queensland local council as an environmental specialist to help support the internal team to achieve sustainable outcomes for the community.
