MF24027Contributions of nano- and picophytoplankton to the phytoplankton biomass in Saudi Arabian waters of the Arabian Gulf

Moritz J. Heinle 0000-0003-0945-9283, Ace V. Flandez, Todd R. Clardy, Hattan Balkhi and Mohammad A. Qurban
 

This study reports on the contribution of three phytoplankton size classes to the total chlorophyll-a (Chl-a) concentration at three coastal stations in the Arabian Gulf. It included data on the seasonal cycle for total chlorophyll a, as well as for the three size classes, and indicated physicochemical parameters potentially driving these cycles. It was found that micro- and nanophytoplankton Chl-a are correlated to a similar set of physicochemical parameters, whereas picophytoplankton Chl-a has a distinctly different correlation model.

MF24041Residency and movement patterns of juvenile yellowfin bream Acanthopagrus australis, stocked on estuarine artificial reefs

Alistair Becker 0000-0001-5578-7208, Symon A. Dworjanyn, Benjamin Mos 0000-0003-3687-516X, Yuri V. Niella, James A. Smith, Michael B. Lowry and Matthew D. Taylor 0000-0002-1519-9521
 

Successful fish stocking relies upon releasing cohorts directly into habitat containing suitable supporting resources. We compared residency and movement patterns of juvenile yellowfin bream stocked on artificial reefs and less complex natural habitat. Fish stocked on artificial reefs showed greater fidelity to their release site and were detected for longer periods. Future stocking of bream or other sparids should consider releasing fish onto artificial reefs, with benefits these structures provide likely to be greater for estuaries lacking naturally complex habitats.

This study showed the presence of juvenile olive ridley turtles in north-eastern Brazil, with 62.04% of 266 records being juveniles, including ‘lost years’ individuals up to 25.9 cm. Anthropogenic interaction with fishing (83.02%) is the main cause of strandings. The north-eastern region is vital as a habitat, necessitating continuous monitoring and conservation, particularly in heavily fished areas.

MF24067Realising the benefits of modern fish-protection screening in Australia

Thomas S. Rayner 0000-0001-9616-1068, Craig A. Boys 0000-0002-6434-2937, John Conallin 0000-0002-2508-1930, Boyd Blackwell, Anthony Moore, Marita Pearson and Rodney Price
 

Modern fish-protection screens are implemented globally to conserve aquatic ecosystems and infrastructure. They safeguard up to 90% of fish from water diversions, with Australian governments investing ~A$40 million in incentive programs. Progress in New South Wales includes screening 36 pumps from 2018 to 2024, protecting over 819,000 native fish yearly and delivering cleaner water for agriculture. Challenges remain in cost management and national expansion, necessitating prioritisation, affordability, industry stewardship, and ongoing advancements towards widespread adoption.

MF24080No effects of abiotic and anthropogenic factors on reef-associated neonate shark abundance within a shark nursery-area system

I. A. Bouyoucos 0000-0002-4267-1043, C. A. Simpfendorfer, G. D. Schwieterman, K. B. Eustache, Lauric Thiault, S. Planes and J. L. Rummer
 

Coastal waters can be crucial nursery grounds for young sharks, but these areas are subject to a wide range of environmental changes and human interference. Our study found no significant effects on newborn populations of two reef shark species. This indicates either their remarkable resilience to environmental shifts and human presence in their habitats, or that these populations are historically degraded.

MF24063Eutrophication weakens the positive biodiversity–productivity relationship of benthic diatoms in plateau lakes

Yun Zhang 0000-0002-9455-4711, Yihan Zhao, Yanling Li, Xiaodong Wu, Janne Soininen 0000-0002-8583-3137 and Jun Wang 0000-0003-2481-1409
 

This study examined the benthic diatom biodiversity–productivity relationship (BPRs) and the underlying mechanisms in high-plateau lakes along trophic states. The BPRs were linear and positive at all trophic levels, but eutrophication may weaken this relationship. Motile, non-attached and small-sized cells contributed notably to reducing the productivity and BPR. Nutrients affected productivity indirectly by influencing algal community structure, niche width and by biodiversity change.

MF23174Are tuna always hungry? A deep dive into stomach-fullness measures in the western and central Pacific Ocean

Pauline Machful 0009-0006-1926-8594, Annie Portal, Jed Macdonald, Valerie Allain, Joe Scutt Phillips, Joanne Potts and Simon Nicol
 

In this study, we sought to reconstruct tropical tuna dietary histories by using different metrics of stomach fullness and to assess their association with fisheries-related, environmental and biological covariates. Our results add to the evidence that tropical tunas forage more effectively during the day and more actively when not associated with floating objects. Further research is needed to understand the factors governing this promising indicator of ecosystem change.

MF24123The implications of brief floodplain inundation for local and landscape-scale ecosystem function in an intermittent Australian river

Oliver P. Pratt 0000-0001-7323-4594, Leah S. Beesley 0000-0003-4850-6388, Bradley J. Pusey 0000-0002-7446-7186, Samantha A. Setterfield 0000-0002-7470-4997 and Michael M. Douglas 0000-0003-3650-3374
 

Seasonal flooding promotes habitat diversity that influences biodiversity and ecological processes in river–floodplain ecosystems. We demonstrated that environmental conditions in floodplain pools on the Fitzroy River (WA) vary substantially compared with the main channel, providing an important habitat for organisms that contribute to landscape-scale ecosystem function. Floodplain pools fill a unique role in the wider river–floodplain ecosystem and should be protected from negative effects of water development.

MF24118A comprehensive review of South Australia’s Great Artesian Basin spring and discharge wetlands biota

P. G. Beasley-Hall 0000-0002-7360-7933, B. A. Hedges, S. J. B. Cooper, A. D. Austin and M. T. Guzik
 

The Great Artesian Basin (GAB) is Australia’s largest freshwater resource. Springs fed by the GAB support many species not found elsewhere on Earth, but conservation is hindered by a lack of fundamental knowledge about the plants, animals and fungi reliant on these habitats. Using South Australia as a case study, we provide a comprehensive review of GAB biodiversity in that state.
