Summary: Precipitation variation has a profound impact on agricultural development and diffuse pollution risk, potentially undermining the effectiveness of pesticide reduction policies. This study analyzed the response of pesticide discharge loads in a large vulnerable watershed to pesticide application intensity and precipitation variance before and after the implementation of pesticide reduction policies. The results showed that the policies successfully reduced the annual discharge load of the pesticide atrazine within the watershed. Furthermore, the sensitivity of atrazine discharge loads shifted from precipitation to pesticide application intensity after the implementation of the policies, although discharge loads significantly increased in an abnormally high precipitation year in the context of increasing precipitation variability.

Summary: This study explores the multidimensional landscape effects on stream water nitrogen and finds that the riparian buffer zone with a width of 400 m has the most significant influence on NH4-N and TN levels. Within this buffer zone, different key landscape metrics can explain 43.35%-76.55% of the total variation in river N levels. Additionally, reference thresholds for triggering abrupt increases in NH4-N and TN levels are identified.

Summary: Over-application of manure to agricultural fields can result in nitrate contamination of groundwater, with high spatial variability and long-term effects. This study evaluated the factors influencing the distribution of nitrate in shallow groundwater after long-term manure application. The results showed that cumulative manure loading had the greatest control on nitrate distribution, and a decreasing temporal trend was observed in wells where manure application ceased. Isotopic analysis revealed denitrification processes and the impact of historical nutrient and water management practices on groundwater quality.

Summary: Predicting the response of water quality and quantity to climate change in a watershed is challenging due to complexity and uncertainties. However, hydrological models like the Soil Water Assessment Tool (SWAT) can simplify the processes and predict the impacts of agricultural activities. This study evaluated the applicability of SWAT in predicting streamflow and nitrate load in an agricultural Mediterranean watershed and found that the model performed well during calibration and validation. Climate change projections showed a decline in streamflow and nitrate load, with the long-term projection scenario of RCP8.5 being greatly affected.

Summary: Nitrogen inputs in agricultural systems have significant impacts on soil nitrate concentrations, increasing NO3- leaching and groundwater contamination. Previous studies have mainly focused on the role of soil microbes in regulating NO3- concentrations in the topsoil, neglecting their influence in the subsoil. This study examined the relationships between microbial properties and NO3- concentrations in both the topsoil and subsoil, revealing the important role of microbial regulation in subsoil NO3- concentrations.

Summary: Subtropical systems experience occasional severe floods that lead to significant changes in phytoplankton community structure. A study in an Australian subtropical bay found that a 1:100 year summer flood resulted in rapid shifts from micro-phytoplankton dominance to nano- and pico-plankton dominance. This shift was attributed to increased nutrient availability stimulating the growth of smaller phytoplankton species.

Summary: Restoring riparian zones with woody vegetation can help protect waterways from sediment and nutrient pollution, but leaf litter can lead to dissolved organic matter leaching into surface waters, generating disinfection by-products (DBPs) during water treatment. The study compared the DBPs formed from leachate of two native Australian riparian trees, finding that Eucalyptus tereticornis leachates produced more DBPs and induced greater toxicity in bioassays compared to Casuarina cunninghamiana and reservoir water. Different tree species have unique DBP profiles, with E. tereticornis posing a greater risk to drinking water quality.

Summary: The study showed that fluorescence measurements of mixed cyanobacteria populations can be accurately estimated, with a stronger correlation to biomass instead of cell count. Errors in fluorescence estimations were found to be larger for species with different morphologies, while converting fluorescence to biomass helped reduce species-specific bias. Best practices for fluorometer deployment and operation, along with data-driven models for in-situ calibration, are discussed as solutions to minimize taxa-specific bias in fluorescence estimates.

Summary: Flow is a fundamental driver of ecological processes in river networks and estuaries. In this study, the researchers explored how changes in river flow regime influenced the structure of benthic communities in three estuaries in northern Australia's Gulf of Carpentaria. They found that the number of consecutive days of zero river flow during the preceding dry season best explained inter- and intra-annual patterns in benthic community composition. The study also revealed that the regional taxa pool currently contains enough functional redundancy to maintain abundances and biomasses under various physicochemical conditions.

Summary: Targeting catchment nutrient critical source areas (CSAs) can help prioritize remediation sites for reducing nutrient runoff. The soil slurry approach can be used to identify potential CSAs within individual land use types, examine fire impacts, and identify the contribution of leaf litter to nutrient export. The slurry results were validated through comparisons with stream monitoring data and showed consistent differences in nutrient ratios and export contribution. The slurry method can account for impacts of vegetation and bushfires, providing valuable information for catchment restoration actions.

Summary: The inter-relationships between cellular phosphorus (P) storage, dissolved inorganic P (DIP) uptake affinity, alkaline phosphatase activity (APA) and dissolved inorganic nitrogen (DIN) concentrations were studied in two ubiquitous diazotrophic freshwater cyanobacteria, Raphidiopsis raciborskii and Chrysosporum ovalisporum. The study showed that DIP uptake of individual strains followed Michaelis-Menten kinetics, but differed with DIN and P availability, and between growth stages. Our results indicate that cyanobacterial species and strains differ in their strategies to P limiting conditions, and highlight the interplay between N and P.

Summary: River run-off is considered to be a major source of organic-rich suspended particulate matter (SPM) in the Great Barrier Reef (GBR), but the origin of this SPM remains uncertain. Through multiple lines of evidence, it has been found that a significant portion of the land-derived SPM is degraded in the mixing zones of rivers and estuaries before being transported offshore. The fingerprints of SPM in the marine environment are different from those of terrestrial origin and more consistent with those formed by marine phytoplankton. This suggests that the SPM in the GBR may be produced locally in the marine environment.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
