Summary: Hypolimnetic withdrawal (HW), a lake restoration method based on phosphorus removal, faces the challenge of balancing effective P removal with maintaining thermal stratification. By adjusting withdrawal rate and using diffusive fluxes, it is possible to remove phosphorus without disturbing thermal stratification and shift the P budget of the lake to negative, showing great potential for lake restoration. Optimizing HW based on diffusive flux of P and utilizing a closed-circuit system could further enhance its effectiveness.

Summary: Advances in high-frequency water quality measurements have allowed for a better understanding of the relationship between hydrological flushing and biogeochemical cycling in streams. Diel cycles in water quality time series, even during storm events, indicate that biogeochemical processes are not always suppressed. Different water quality parameters exhibit diverse responses to storm events, with storm magnitude and timing playing a critical role in controlling mobilization, flushing, and cycling behavior.

Summary: The termination of the Marinoan global glaciation led to the diversification of eukaryotes and possibly the occurrence of animals, suggesting a potential linkage between biological evolution and global glaciation. The study on the marine carbon and sulfur biogeochemical cycles during the Nantuo glaciation in South China revealed active biogeochemical cycles, indicating sustained habitability and survivorship in the pan-glacial ocean. The delayed recovery of marine productivity may have imposed environmental stress for millions of years, paving the way for the evolution of animals.

Summary: Estuarine intertidal sediments play a vital role in organic matter remineralization and nutrient recycling. This study investigates the seasonal biogeochemical cycles in three types of intertidal sedimentary habitats in the Western Scheldt estuary. The results show that environmental conditions determine the local nutrient dynamics, with temperature controlling sediment oxygen consumption rates and nutrient fluxes. The sediments remove a significant amount of nitrogen and phosphorus entering the estuary and also reveal the positive impact of water treatment policies on water quality. This study highlights the importance of intertidal sediments in estuarine systems and provides valuable insights for modeling estuarine biogeochemistry and climate change scenarios.

Summary: The novel combinations of climatic conditions and prolonged fire seasons caused by climate change have led to an increased occurrence of megafires. These large-scale fires pose an unknown threat to biodiversity due to the increased extent and severity of burn. This study assessed the impacts of the 2019-2020 Australian wildfires on estuarine benthic sediment communities using eDNA techniques, revealing that estuaries from burnt catchments with no buffer showed greater dissimilarities in composition and abundance compared to those with an intact buffer or from unburnt catchments. The changes in sediment community composition and abundance were associated with increased concentrations of nutrients, carbon, including fire-derived pyrogenic carbon, and copper in highly burnt catchments.

Summary: Over the last century, human activities have increased nutrient inputs to ecosystems, altering nitrogen and phosphorus cycling and impacting ecosystem function. Reef-forming shellfish can enhance nutrient cycling, particularly nitrogen removal, by providing substrate for microbial colonization and enhancing microbial denitrification in sediments. However, the effectiveness of shellfish in enhancing nutrient cycling varies spatially and in response to environmental factors.

Summary: This study investigates the effects of increasing habitat complexity on biodiversity and ecological functions. The results show that increasing physical and biogenic complexity can enhance species richness but does not necessarily affect productivity. Therefore, when implementing eco-engineering practices, it is important to consider the trade-off between biodiversity and functional targets.

Summary: Despite low surface concentrations, phosphorus (P) availability in marine environments is crucial for biological processes. Picocyanobacteria strains possess a putative phosphorus transporter, PhnDCE, but lack the ability to degrade phosphite or utilize alternate phosphorus sources. Our study found that Synechococcus PhnD1 proteins selectively bind phosphorus compounds, with a higher affinity for phosphite. However, growth experiments showed that Synechococcus strains cannot utilize phosphite as a sole phosphorus source, suggesting that the PhnDCE transporter is a constitutively expressed, medium-affinity phosphate transporter.

Summary: This study investigated nitrogen cycling in oyster reef habitats along the East coast of Australia by assessing the abundances of nitrogen cycling genes in oyster shell biofilms and surrounding sediments. The study found higher abundances of denitrification gene nosZII in oyster shell biofilms, indicating a greater capacity for nitrogen removal. The ratio of (nirS + nirK)/nosZII in oyster shell biofilms was lower, suggesting limited nitrous oxide release compared to sediments. The abundances of nitrogen cycling genes in sediments were influenced by large-scale environmental conditions.

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.
