Summary: CyanoHABs in Harsha Lake shifted from N2 fixer-dominated Anabaena to non-N2 fixer-dominated Microcystis and Planktothrix as nitrogen supply decreased. The concentrations of cyanotoxins were significantly higher when nitrogen became limited. Water quality results indicated significant correlations between nitrogen species, water temperature, and cyanobacterial biomass. Additionally, the expression levels of certain C- and N-processing-related cyanobacterial genes were highly predictive of species biomass.

Summary: This study developed a framework called mixNanohealthrisk to provide exposure limit or reference dose for co-occurring nanoparticles in water for different regions. The top three risk-posing nanoparticles were identified as CuO, ZnO, and TiO2 when co-occurring together. The regions with the highest risk quotient were found to be USA, Switzerland, and Europe.

Summary: Phosphorus is an essential nutrient for phytoplankton growth and regulates the succession of diatoms and dinoflagellates blooms in the East China Sea. This study investigated the growth interactions among major bloom-forming species and revealed that the survival strategies of Prorocentrum donghaiense and Karenia mikimotoi were superior to Skeletonema costatum in bi-algal cultures. The competition results varied with different P concentrations and sources, providing evidence for understanding the bloom succession in the ECS.

Summary: This study investigates the influence of host genotype on microbiomes in co-occurring asexual and sexual genotypes of the same species. Results show that clones with similar host genotypes have similar bacterial composition and functions, while sexual genotypes differ from them. Therefore, factors regulated by host genotype, such as secondary metabolite production, likely drive differences in microbial communities between different host morphs. This study highlights the importance of genetic relatedness of hosts in determining variability in their bacterial symbionts.

Summary: This study demonstrates the biosynthetic pathways of five benzoic acid derivatives through microbial co-culture and confirms the effects of microbial co-culture on microbial morphology. It provides insights into the interactions among microorganisms and offers new ideas for studying the biosynthetic pathways of newly induced secondary metabolites in co-culture.

Summary: The transcriptional responses of Saccharomyces cerevisiae to different non-Saccharomyces species were studied, revealing an overexpression of the gluco-fermentative pathway and strong repression of the respiration pathway in response to Metschnikowia pulcherrima. Under excess sugar conditions, a direct interaction stress response between S. cerevisiae and other yeast species may induce transcription of hexose transporters, leading to increased glucose flow to fermentation and inhibition of respiration.

Summary: Habitat heterogeneity is a primary driver of biodiversity patterns, but its universal role has not been fully understood due to a lack of coordinated experiments. This study conducted 22 experiments to assess the impact of habitat heterogeneity on biodiversity across different ecosystems and regions, and found that positive and additive effects were common across the three axes of heterogeneity. These findings provide mechanistic insights into the importance of habitat heterogeneity in promoting biodiversity through facilitative interactions.

Summary: Several studies have found that invasive plant species are more negatively affected by drought than native plant species. However, little is known about how drought-rewetting events affect the growth of invasive and native plant species, both directly and indirectly through soil microorganisms. This study used a factorial design to investigate the effects of drought and rewetting on four pairs of invasive and native plant species. The results showed that invasive plant species experienced a greater decline in biomass during drought, but exhibited a stronger recovery following rewetting compared to native plant species. Additionally, soil microorganisms facilitated greater recovery from drought in invasive plant species than in native plant species.

Summary: In freshwater ecosystems, the interaction between algae and heterotrophic bacteria may lead to the formation of bacterial populations with the ability to degrade phosphonates, increasing the proliferation capabilities of cyanobacteria. Metatranscriptomic analysis of aggregate samples suggests that the cooperation between algae and heterotrophic bacteria plays a crucial role in the proliferation of cyanobacteria.

Summary: The study revealed that temperatures of 6 and 12 degrees C were the most suitable for bar storage, while storage at 20 degrees C had a negative impact. Retempering immediately after production can enhance the resistance of chocolate bars to fat bloom, although it may affect sensory quality at the beginning of the storage period.

Summary: The study found that tamarack and black spruce exhibit divergent responses to climate warming in terms of leaf nitrogen content, with an increase in leaf nitrogen leading to higher photosynthesis in tamarack but not in black spruce. Surprisingly, dark respiration in black spruce did not acclimate to warming, and thermal acclimation of respiration was only observed in tamarack after considering changes in leaf nitrogen. This highlights the different stomatal responses to warming in co-occurring species, impacting vegetation carbon and water dynamics.

Summary: The spatial shoot organization of dune grass species varies between sand couch and marram grass, with sand couch having a dispersed organization and marram grass having a patchy organization. The shoot organization of marram grass varies based on environmental conditions, while sand couch maintains a fixed expansion strategy.

Summary: Lichens, as symbiotic entities between fungi and photosynthetic partners, may acquire toxic features due to toxin-producing fungi, algae, or cyanobacteria. Special attention is paid to common toxins such as microcystin and nodularin produced mainly by the genus Nostoc. The effective application of modern research methods in addressing lichen toxicity related to cyanobacterial partners is emphasized.

Summary: The study revealed that multiple diatom species co-occurred during spring diatom blooms in a temperate freshwater system, with Cyclotella sp. being the main contributor to the bloom attributed to S. hantzschii. DNA metabarcoding proved to be a useful tool for identifying species in these blooms, and the co-occurrence of similar species should be considered in monitoring and controlling efforts.

Summary: Advances in multi-species monitoring have led to the widespread use of multi-species occupancy analyses. However, these analyses often assume that survey sites are closed to changes in occupancy. Violating this closure assumption can lead to erroneous conclusions about patterns of co-occurrence among species. Simulations show that when closure is violated, co-occurrence models often fail to detect patterns of avoidance or aggregation, and instead incorrectly identify a pattern of independence among species. This has important implications for our understanding of species interactions and conservation efforts.
