Summary: Microbial interactions play a critical role in community stability and niche spaces in all ecosystems. However, it is still unclear what factors influence these interactions and lead to changes in species fitness and ecological niches. This study investigated the effects of metabolic similarity and resource availability on niche deformation and interactions between bacterial species. The results suggest that metabolic similarity drives niche changes between species and resource limitation increases microbial inhibition and negative interactions. Furthermore, high resource availability promotes niche expansion and facilitates positive interactions between bacteria. These findings demonstrate the importance of metabolic similarity and resource availability in modulating microbial interactions and altering bacterial niches.

Summary: Persistent eutrophication can lead to toxic algal blooms, posing a serious threat to drinking water safety, food security, and public health. This study proposes a new framework for analyzing the spatial patterns of nutrient loads and thresholds in large shallow lakes. The results show significant spatial differences in nutrient loads and thresholds among different areas of the lake, which are valuable for watershed nutrient management and ecological restoration of lakes.

Summary: The study found that the light-to-nutrient conditions in alpine lakes can limit bacteria, with significant differences in environmental conditions between lakes above and below the treeline. Lakes above treeline exhibited phosphorus limitation, while lakes below treeline had reduced phosphorus limitation due to high allochthonous organic matter input.

Summary: The bacterial community in sediments of lakes dominated by macrophytes and lakes without macrophytes show different sensitivities to excessive nutrients. Bacterial communities in macrophyte-dominated areas are more susceptible to changes in nutrient levels and have lower stability compared to macrophyte-free areas.

Summary: When bacterial communities mix, the immigration history can have a fundamental impact on their composition due to priority effects. The strength of priority effects depends on the environmental conditions, with greater effects observed when the conditions favor the growth of the first arriver.

Summary: In this study, the bacterial community structures and metabolic functions in urban landscape lakes in Xi’an were analyzed. The results showed clear seasonal and spatial differences in bacterial diversity and distribution, with temperature, dissolved oxygen, and nitrogen being the primary factors affecting the seasonal variation in bacteria. The study provides important insights into the current status of bacteria in urban landscape lakes.

Summary: The enrichment of nutrients in lakes due to municipal wastewater discharge and agricultural run-off leads to excessive growth of algae and aquatic macrophytes, altering their trophic states. This study demonstrates that as trophic state increases, the elemental content in aquatic macrophytes also increases, along with biomineral depositions in leaf anatomy.

Summary: The oxygen content in the heap composting pile decreases with depth, leading to aerobic, facultatively anaerobic, and anaerobic fermentation in different layers. This study investigated the temporal succession and spatial heterogeneity of humification, pathogens, and bacterial community in facultative heap composting. Pig manure alone or mixed with cornstalk was composted for 90 days without ventilation or turning, and different compost layers exhibited discrepancies in maturity and bacterial community. Cornstalk addition improved compost maturity, humification, bacterial diversity, and cooperative interactions, as well as the transformation from anaerobic to aerobic bacteria by enhancing porosity and oxygen diffusion. However, it also slowed down pathogen reduction.

Summary: The impact of environmental nutrient availability on T cell metabolism and function is not well understood. This study found that physiologic carbon sources (PCSs) in cell culture medium have a broad impact on glucose utilization by CD8(+) T cells, independent of transcriptional changes in metabolic reprogramming. PCSs reduce glucose contribution to the TCA cycle and increase the effector function of CD8(+) T cells, with lactate directly contributing to the TCA cycle.

Summary: The clearing of riparian forests can significantly alter macroinvertebrate richness and community composition in streams, with different dominant biological communities in different types of watersheds. Taxonomic composition is controlled by forest cover and available organic material, while functional composition is influenced by periphyton regardless of riparian buffer presence.

Summary: Recent advancements in high-frequency environmental sensing and statistical approaches have expanded the knowledge of aquatic ecosystem metabolism, particularly in measuring and interpreting gross primary productivity (GPP) and ecosystem respiration (ER). These advancements have made it easier to monitor dissolved oxygen (DO) and key physical processes in aquatic ecosystems, aiding in environmental management and monitoring. Despite challenges, developments in modeling metabolism have brought us closer to utilizing real-time estimates of GPP, ER, and gas exchange to improve environmental assessment and management.

Summary: This study in the Brazilian Amazon found relatively subtle differences in stream function between forested and cropland streams, with cropland streams having lower OM biomass and greater seasonality in ecosystem respiration and net ecosystem production. Streams were found to be more retentive of phosphorus than nitrogen, indicating that fertilizer nitrogen reaching streams will be exported in stream networks.

Summary: The future of comparative psychology relies on early-career scientists, yet scholars from marginalized groups are disproportionately underrepresented in the field. New approaches to sponsorship, mentoring, and community building are needed to retain talent from marginalized communities and create a culture where all individuals can thrive. Initiatives like peer coaching circles can empower marginalized scholars and professional societies play a crucial role in investing in the success and career development of underrepresented individuals.

Summary: This paper examines how a diverse group of women in academic engineering supported early-career women by drawing on data from the NSF-funded LATTICE program. Using ethnography, the authors analyze the social dynamics and power relations involved in forming a coherent group identity for the leadership team of LATTICE. They identify processes and behaviors that help build a coherent community across various dimensions of difference and offer actionable strategies for change agents working across intersecting dimensions of difference.
