MF24017Recognising diversity in wetlands and farming systems to support sustainable agriculture and conserve wetlands

Anne A. van Dam 0000-0002-5073-7241, Hugh Robertson, Roland Prieler 0009-0002-7256-6882, Asmita Dubey and C. Max Finlayson 0000-0001-9991-7289
 

A review of the impacts of food production on wetlands underlined the need for transforming food production to achieve sustainable wetland management. Sustainable agriculture–wetland interactions can be achieved by more efficient use of water and fertilisers, integration of crop–livestock–fish production, better support for small producers, and governance of food production that recognises the ecosystem services of wetlands in catchments.

MF24160Repairing Australia’s inland river and groundwater systems: nine priority actions, benefits and the finance gap

S. J. Capon 0000-0002-1975-553X, C. M. Steinfeld, J. Pittock 0000-0001-6293-996X, B. J. Moggridge, A. Ward, L. J. Baumgartner, F. Sheldon 0000-0001-9944-6392, M. Ward and D. L. Medaris
 

We propose and cost nine priority actions to repair inland river and groundwater systems in Australia, including riparian revegetation, surface and groundwater recovery and management of barriers to flow and fish movement. Our estimates suggest approximate annual investment from 2025 to 2054 of A$3.1 billion (2022 dollar values). Revenue generated through the carbon market through riparian restoration could cover between 37 and 72% of the costs, reducing investment needed to between A$0.9 billion and A$2.0 billion. We highlight opportunities for Indigenous nations to implement associated on-ground works.

MF24162A grey nurse shark from the Northern Territory of Australia shares a mitochondrial haplotype only recorded from the western Australian population

Sara Krause 0009-0006-1744-5999 and Adam Stow
 

The grey nurse shark (Carcharias taurus) is a Critically Endangered species with two genetically distinct Australian populations. An individual caught outside the species’ known distribution range off the Northern Territory of Australia was found to be genetically compatible with the western Australian population and not with the more highly endangered eastern Australian population. Our results imply a possible extension of the western Australian population and are useful baseline information for the development of conservation strategies for grey nurse shark in northern Australian waters.

MF25023Attributes and effects of the invasive air-breathing freshwater snail Physa acuta on ecosystem properties and services

Gonzalo A. Collado 0000-0001-9076-4255, Cristina Damborenea, Gustavo Darrigran and Álvaro Alonso
 

Freshwater ecosystems face significant disruption from non-native species such as the sewage snail (Physa acuta). Our study comprehensively assesses its impacts on ecosystem services, showing that negative effects outweigh positive ones, particularly in cultural and provisioning services. Although it harms many services and native fauna, it can serve as a bioindicator, highlighting the need for thorough evaluations of invasive species.

MF24221Developing geospatial tools to identify refuges from alien trout invasion in Australia to assist freshwater conservation

Hugh Allan 0000-0002-0251-7332, Richard P. Duncan, Peter Unmack, Duanne White and Mark Lintermans
 

Introduced predatory fish species have caused small-bodied fish to decline worldwide. Some native fish now exist only in headwater streams where they are protected from invasive introduced species by barriers such as waterfalls. We explored the use of remote-sensing technology to improve processes to find and characterise these barriers and assist with future freshwater fish conservation.

MF23164Spatial and temporal habitat use of humpback whales (Megaptera novaeangliae) in relation to vessel traffic in the Gold Coast Bay, Australia

Jana Djukaric 0000-0002-3108-1697 and Jan-Olaf Meynecke 0000-0002-4639-4055
 

Humpback whales frequent Gold Coast Bay, Australia, for breeding, resting, and migration, facing vessel traffic. This study used 4319 citizen science whale sightings (2011–20) to map whale habitats. Calving pods stayed near shore, overlapping with non-calving pods further in the bay. Vessels affected up to 80% of these areas, endangering mother–calf pods. Evaluating all bay-bound vessels is suggested to safeguard the whales.

MF24130Trends in eastern blue groper (Achoerodus viridis) abundance along south-eastern Australia (New South Wales): the influence of latitude, climate change and potential depth refuges

Nathan A. Knott 0000-0002-7873-0412, Matthew J. Rees 0000-0002-2472-6215, Tom R. Davis 0000-0003-0199-2024, David Harasti 0000-0002-2851-9838, Hamish A. Malcolm, Matthew D.

Eastern blue groper (Achoerodus viridis) is an iconic Australian rocky-reef fish, and we analysed its abundances for more than a decade across the New South Wales coastline. Blue groper was most abundant in temperate rather than subtropical waters along this coast. Its abundances were stable on deeper reefs, but declined steadily through time on shallow reefs. This pattern indicates that blue groper is declining because of warming oceans, although deeper reefs may provide a thermal refuge.

Hypersaline waters are some of the most extreme habitats but have high productivity, and the potential to support bird diversity as well as develop multi-species aquaculture. We provide new information on interactions between seagrass Ruppia and zooplankton in those waters, which gives a better understanding of unique ecosystems and is valuable for the management of hypersaline water bodies and the development of sustainable polyaquaculture in them.

MF24109Australians’ perceptions of species diversity of, and threats to, the Great Barrier Reef

Jarrah Taylor, Carla Litchfield and Brianna Le Busque 0000-0002-9096-1897
 

This study investigated Australian’s knowledge of the Great Barrier Reef, including which threats the reef is facing and which species reside on the reef. We found that Australians listed various environmental and social threats to the reef, and that clown fish were the most commonly listed specific species, perhaps owing to the popularity of film Finding Nemo.

MF24147Effects of prolonged starvation on body mass and respiratory physiology of the New Zealand abalone or pāua, Haliotis iris

Islay D. Marsden 0009-0007-0904-9344 and H. Harry Taylor
 

The effects of 105 days of starvation on body mass, respiration and haemolymph proteins were measured in two groups of pāua, one group where the haemolymph was sampled at intervals and the other which was sampled only at the start and end of the experiment. Fed individuals increased body mass, whereas starved individuals lost body mass and condition. Paua survive extended periods of starvation by metabolising haemocyanin and are able to survive stressors associated with low food availability.

Lakes, creeks and floodplains that are situated away from the main channel are likely to play important roles in the ecology of inland rivers. These isolated areas provide habitat for endangered species as well as nursery areas for resident fauna, and data obtained from such areas should inform research and management projects at catchment scale.
