Summary: The usability of Ligula intestinalis as a bioindicator for pesticide accumulation was examined in this study. Two experiments were conducted to detect pesticide residues and withdrawal period, respectively. The results showed that the presence of malathion was detected in both fish and L. intestinalis in the experimental group, while no malathion residue was found in the control group. It was also found that malathion accumulation exhibited a linear correlation between infected and uninfected fish, while an inverse correlation was observed between L. intestinalis and both malathion and control fish. Therefore, L. intestinalis can be used as a bioindicator for pesticide accumulation, and the pesticide can still be detected in the parasite after withdrawal from fish.

Summary: A novel electrochemiluminescence (ECL) biosensor with multiple signal amplification strategy was constructed for ultrasensitive detection of malathion. The ECL signal was amplified by immobilizing Ru(bpy)32+ (as luminophore) on hydroxyapatite (HAP) and further increased by modifying Au@ZIF-7 nanocomposite (as coreaction promoter) to the electrode surface. Acetylcholinesterase (AChE) was loaded on the porous Au@ZIF-7 to enhance the selectivity of the sensor. The method showed wide linear range and high sensitivity in detecting malathion, with potential application prospect in OPs detection.

Summary: In this work, polyaniline (PANI) and overoxidized polyaniline (oPANI) nanorods doped by phytic acid (PA) were prepared as non-enzymatic malathion sensors. PA doping had a significant influence on the structural and morphological properties, conductivity, and detection performance of the electrode materials. PA-PANI exhibited high affinity towards malathion, hindering the redox reaction of PANI molecules, while PA-oPANI showed good catalytic performance, enhancing the electron transfer process. Both enzyme-free electrochemical sensors exhibited excellent stability, anti-interference ability, recovery in real samples, and wide linear ranges with low detection limits, indicating their potential as malathion sensors. Further exploration is needed for the reproducibility of the PA-oPANI sensor through anodic polarity processing.

Summary: Human-mediated salinity increases have negative effects on freshwater biodiversity globally. It is important to consider individual ion concentrations and ion ratios in addition to total concentrations when determining the effects of salinity. Single-species laboratory tests may not accurately predict the impact of different salt sources on populations and communities. This study compared the effects of synthetic marine salts and sodium bicarbonate on stream macroinvertebrates in an outdoor mesocosm experiment in southeastern Australia.

Summary: The 96-h acute toxicity of barium (Ba2+), o-cresol, and sodium chloride (NaCl) to Paratya australiensis was assessed in single, binary, and ternary combinations, and three biochemical assays were conducted to evaluate their toxic effects. The results showed that o-cresol had the highest mortality rate, followed by NaCl and Ba2+. The combined exposures of the toxicants resulted in more than additive effects, with the ternary combinations showing highly synergistic interactions. There were no significant enzyme activity trends observed in both individual and mixture exposures.

Summary: Amphipods are widely distributed in aquatic environments and play an important role in nutrient cycling, making them ideal indicators for biomonitoring and ecotoxicological studies. In this study, marine amphipods were exposed to copper, pyrene, and their mixtures for different durations, and changes in polar metabolites were assessed using GC-MS-based untargeted metabolomics. Limited metabolite changes were observed for single exposures, while mixtures had a greater impact on metabolites. The results highlight the sensitivity of metabolomics in assessing the effects of low concentrations of chemicals compared to traditional ecotoxicological endpoints.

Summary: Australia has implemented the Murray Darling Basin Plan to address water resource overallocation in the Murray-Darling Basin. However, the impacts of climate change on surface runoff and water demand may undermine the achievements of the plan. It is crucial to learn from the past two decades and adapt to climate change. Managers have three options: continue with current adaptive management, focus on a subset of sites, or shift to a more functional flow regime. Climate change requires more than incremental adaptation and necessitates substantial changes to the Basin Plan.

Summary: How people value rivers, wetlands and floodplains influences their attitudes, beliefs and behaviors towards these ecosystems, and can shape policy and management interventions. Better understanding why people value rivers, wetlands and floodplains and their key ecosystem components, such as vegetation, helps to determine what factors underpin the social legitimacy required for effective management of these systems. This study sought to ascertain perspectives on the value of non-woody vegetation in river-floodplain systems via an online survey. The survey found that participants valued non-woody vegetation for their provision of a range of ecosystem functions and services, with strong emphasis on ecological aspects such as regulation functions, habitat provision and biodiversity. However, the inclusion of a question framed to focus on stories or narratives resulted in a different emphasis. Responses indicated that non-woody vegetation, and rivers, wetlands and floodplains were valued for the way they made people feel through lived experiences such as recreational activities, personal interactions with nature, educational and research experiences. This highlights the important role of storytelling in navigating complex natural resource management challenges and ascertaining a deeper understanding of values that moves beyond provision of function to feeling. Improved understanding of the diverse ways people value and interact with river-floodplain systems will help develop narratives and forms of engagement that foster shared understanding, empathy and collaboration. Appreciation of plural values such as the provision of functions and services along with the role of emotional connections and lived experience will likely increase lasting engagement of the general public with management to protect and restore river-floodplain systems.
