Summary: Excessive anthropogenic nutrient input has led to eutrophication and algal blooms in aquatic ecosystems. This study in Xiangxi Bay, China, found that nutrient limitation on algal growth fluctuated from nitrogen to phosphorus limitation during the flood season. Nutrient dilution and enrichment bioassays showed that targeted thresholds for total nitrogen and total phosphorus concentrations can help control algal growth and maintain chlorophyll a levels. Dual nutrient reductions were recommended for long-term bloom mitigation. This study provides a scientific basis for nutrient management strategies to combat eutrophication and reduce algal bloom potentials.

Summary: Traditionally, it was believed that phosphorus (P) fertilization relieved the limitation of soil microbial activity by providing P. Recent studies, however, suggest that the stimulation of microbial respiration is actually due to the release of carbon (C) from soil minerals caused by P, which increases microbially available C and stimulates microbial respiration. This new understanding has implications for interpreting the effects of P fertilization on other soil microbe-mediated processes.

Summary: The Lake in Central Park and Prospect Park Lake in New York City have extremely high levels of cyanobacteria and microcystin. These lakes have elevated levels of orthophosphate relative to dissolved inorganic nitrogen during summer months. Nitrogen consistently limits cyanobacterial populations while green algae are rarely nutrient limited. Adding public drinking water rich in phosphorus and to a lesser extent nitrogen significantly enhances the growth of cyanobacteria.

Summary: The study focused on the effect of coagulation on dephosphorization in reservoir water, comparing the performances of Al-based and Fe-based coagulants. Results showed that aluminum salts had stable advantages in dephosphorization, especially in the initial stage of algal blooms. Factors such as pH, P content, and extracellular organic matter were found to significantly affect the efficiency of dephosphorization.

Summary: This study investigates the response of a coral symbiotic species, Cladocopium goreaui, to phosphorus limitation by examining its physiological performance and transcriptomic profile. The results show that C. goreaui exhibits decreased photosynthetic efficiency and downregulated carbohydrate exporter genes under phosphorus limitation, but enhances carbon fixation, nitrogen assimilation, and energy metabolism. The study also reveals flexible mechanisms of utilizing different dissolved organic phosphorus to relieve phosphorus deficiency. These findings shed light on the survival strategies of symbiotic algae and the potential weakening of their role as an organic carbon supplier under phosphorus limitation.

Summary: There is increasing evidence that soil nutrient availability can limit forest carbon sink capacity, especially in the tropics where a large proportion of Earth's plant biomass is stored. This study analyzed stem growth and foliar elemental composition to assess the limitations of soil nutrients on tropical forest growth, with a focus on nitrogen and phosphorus limitations. Results showed a positive effect of nitrogen and phosphorus fertilization on stem growth and foliar nutrient concentrations, with potential nitrogen-fixing species exhibiting greater growth and nutrient concentrations compared to non-nitrogen-fixers.

Summary: Phosphorus limitation is expected to increase due to nitrogen-induced terrestrial eutrophication, but can be alleviated through transformations of phosphorus pools.

Summary: This study investigated the patterns of plant-microbial N/P limitation in forests across China and found significant divergence between the two. The N/P limitation was disconnected in 42.6% of plant-microbial communities, with only 17.7% of N and 39.7% of P limitations consistent. The divergence was more evident at mid-latitudes, where plants were mainly N limited and microbes were mainly P limited. The findings were consistent with ecological stoichiometry and highlighted the importance of soil chemistry in driving the divergence.

Summary: By calculating the ratio between plant demand and soil supply, researchers conducted a theoretical analysis of nitrogen and phosphorus fertilization experiments to explore interaction formalisms between nutrients. The study revealed that synergistic co-limitation could occur even using Liebig's law of minimum under certain conditions, emphasizing the sensitivity of nutrient interaction categorization to mathematical formulation.

Summary: This study investigated the intracellular polyP metabolism and its regulation in Karenia mikimotoi, a harmful algal bloom species, under varying external phosphorus conditions. The findings suggest that K. mikimotoi has a strong capability to mobilize the intracellular phosphorus pool for growth under phosphorus deficiency, and polyP may not play a crucial role in cellular phosphorus storage in phytoplankton, at least in dinoflagellates.

Summary: Microbial lipids are considered a sustainable alternative to traditional vegetable oils and have gained attention among researchers. This study investigated the impact of limiting inorganic phosphorus and nitrogen sources on cellular lipid biosynthesis in Y. lipolytica yeast, revealing a significant relationship between phosphorus concentration and lipid accumulation. Simultaneously limiting both phosphorus and nitrogen sources promoted lipid accumulation but hindered biomass growth, highlighting the importance of phosphorus as a factor in cultivating oleaginous microorganisms.

Summary: Phosphorus is a key nutrient limiting bacterial growth in the oceans. Marine microbes have evolved strategies to adapt to phosphorus limitation by remodeling membrane lipids. This remodeling affects the interactions between bacteria and protists, potentially leading to more efficient removal of low-phosphorus prey.

Summary: The coral skeletal P/Ca ratio can be used as an indicator of temporal seawater dissolved inorganic phosphorus (DIP), allowing for assessments of oceanographic and climatic impacts on marine biogeochemical cycles. Factors influencing P incorporation in coral skeletons and the partitioning of elements between seawater and coral skeletons remain unclear. In temperature-controlled aquarium culture experiments, it was found that the growth rate of corals may be the direct controlling factor on coral P/Ca ratio.

Summary: Adsorption is an effective method for phosphorus recovery from sewages, and EPS-based and Fe-modified hydrogels showed high adsorptive capacity. The hydrogels could adsorb P via ion exchange and hydrogen bonding mechanisms, and had good performance under a wide range of pH conditions. Coexisting anions did not significantly affect the adsorption process, with the exception of CO32-. Ligand exchange was the major driving force for phosphorus adsorption.

Summary: Rivers play a crucial role in the nutrient input to lakes and the control of river nutrients is significant in mitigating lake eutrophication. Based on a study of 1412 sampling sites in China, it is revealed that phosphorus is the key limiting factor for river nutrient balance in China's rivers.

Summary: Near-term ecological forecasts provide advance notice of changes in ecosystem services and uncertainty partitioning helps improve forecast skill and guide interpretation. The study found that model process specification and initial conditions dominate forecast uncertainty and suggested long-term studies and improved observation protocols for better predictions.
