Summary: The symbiosis between Sphagnum and Nostoc is driven by pH, with certain metabolic exchanges and physiological processes involved. Metatranscriptome analysis revealed insights into the underlying mechanisms of this plant-cyanobacterial interaction.

Summary: Sphagnum mosses in peatlands have varying responses to changes in atmospheric CO2 levels. Low water table hummocks benefit from increased CO2 concentration, while high water table levels suppress photorespiration. Water table levels play a key role in the response of mosses to CO2.

Summary: Urbanization is a severe form of environmental alteration that threatens global biodiversity and ecosystem functions. Our study reveals that the abundance of bird species is influenced by functional traits such as migration strategy, nesting height, foraging technique, and diet. Conservation efforts should focus on preserving intact and extensively managed grasslands to sustain urban bird communities.

Summary: In the past decade, neodymium isotopes have been increasingly used as a tracer of dust influx associated with changes in the Holocene atmospheric circulation. However, the understanding of the sources of sediment supplied to peatlands remains incomplete. This study used neodymium isotopes to reconstruct environmental disturbances in peatlands and found a link between these disturbances and the neodymium isotope signals.

Summary: Host-associated microbiomes can play important roles in the ecology and evolution of insect hosts, but the bacterial diversity in many insect groups, such as ground beetles, remains poorly understood. This study examined the relationship between host environment, traits, and microbial diversity in three distantly related ground beetle species. The results suggest that the bacterial composition and diversity in ground beetles are resilient to changes in host diet, and different tissues within the same beetle harbor unique microbial communities, with secretory cells showing remarkable similarity across species.

Summary: The determinants of riverine chironomid species richness were studied in Central Poland, focusing on environmental factors, seasonality, and different diversity concepts. It was found that depth, Substrate Index (SI), velocity, and dissolved oxygen were significant factors influencing species richness, with summer having a noticeable impact.

Summary: The study assessed spatial patterns and contemporary trends in plankton diversity in the circumpolar Arctic region, revealing significant variations in phytoplankton and crustacean zooplankton diversity across the region, positively correlated with summer air temperature. However, the positive correlation between summer temperature and zooplankton species numbers decreased with increasing latitude, and zooplankton taxonomic richness was lower in the high Arctic compared to the sub- and low Arctic. Furthermore, climatic variables were found to be the most important environmental factors influencing diversity patterns for both phytoplankton and zooplankton.

Summary: The study investigated the impact of environmental factors on zooplankton diversity, abundance, and distribution in Ghrib Dam water body over a 2-year period. It found that water temperature, dissolved oxygen, phosphorus, and nitrate were the most significant factors influencing zooplankton community. The diversity of zooplankton was rich, with fluctuations observed in abundance over the study period.

Summary: This study comprehensively analyzed the variation in epiphytic bacterial communities of Gracilariopsis lemaneiformis at different geographic locations and environmental factors. The findings revealed significant differences in epiphytic bacteria among various locations in China, with environmental factors such as nitrogen and phosphorus playing a key role in shaping the community composition of these bacteria.

Summary: This study used fungal metabarcoding to examine seasonal mycoplankton communities in the surface water of the Maowei Sea. The dominant classes were Dothideomycetes and Sordariomycetes. Ochroconis, Rhodotorula, Perenniporia, and Derxomyces were identified as the best seasonal bioindicators. TOC was found to be the main factor affecting mycoplankton bioindicators and trophic modes. The mycoplankton diversity and trophic modes were influenced by environmental factors such as DIP, DO, and TOC. The study provided insights into the controlling factors and diversity of mycoplankton in the coastal environment.

Summary: The study found that analyzing temporal beta diversity can better understand changes in biodiversity, freshwater plant communities from the 1940s to the 2010s showed different patterns of temporal beta diversity. Changes in hydrophyte assemblages were more pronounced than helophyte assemblages, with the main changes occurring from the 1940s to the 1970s.

Summary: The aim of this study was to analyze the distribution and ecological differentiation of oligochaete species with respect to environmental factors. The results revealed differences in oligochaete communities based on waterbody type and altitude. Total beta diversity was found to decrease with decreasing waterbody size, increasing substrate particle size, river flow velocity, and altitude. The study also identified specific preferences of certain families of Oligochaeta based on waterbody type.

Summary: This study analyzed the Daliyabuyi Oasis in the Taklimakan Desert, and found that the current oasis community can be divided into four types based on dominant species controlled by soil moisture. Variations in groundwater depth and surface water disturbance affect patterns of species diversity. The study concluded that community characteristics are not dominated by a single factor and different water resource types have different effects on maintaining community characteristics.
