Summary: Evidence suggests a strong connection between biodiversity and ecosystem functions in aquatic fungal communities, which can be influenced by environmental variables and leaf-litter traits. Functional redundancy among fungi may counteract the effects of biodiversity changes on ecosystem functioning. Temperature and nutrients impact taxonomic and functional diversity of aquatic fungi in leaf-litter decomposition processes.

Summary: This study investigates the effects of tree species and leaf litter chemistry on fungal community succession during leaf litter decomposition. The results show that closely related tree species have different fungal communities during decomposition, and a high number of fungal species are specific to a particular tree species. Fungal diversity increases at the beginning of leaf decay and declines at the final stages. This study contributes to our understanding of fungal diversity and provides a database for future studies.

Summary: In temperate forests, fungi play a crucial role in the decomposition of leaf litter. However, their influence on the chemical changes in leaf litter remains poorly understood. This study aimed to determine the main factors driving leaf litter chemical transformation during decomposition by conducting a long-term transplantation experiment.

Summary: Dead microbial cells, known as necromass, are important sources of carbon and nutrients in soils. Recent studies have focused on the microbial communities associated with decomposing fungal necromass in different terrestrial ecosystems. This article highlights the ecological patterns and research frontiers of the fungal necrobiome, and suggests that combining laboratory assays with field-based surveys and experiments will enhance our understanding of its composition and role in soil biogeochemical cycling.

Summary: This study analyzed the changes in fungal communities and their functionality during senescence and litter decomposition of the foundation plant species Spartina patens. The research found that different types of plant biomass hosted unique fungal communities and litter chemistry. Functional groups in live biomass were replaced by diverse saprotrophs during senescence, and lignocellulose saprotrophs showed the highest abundance in lower thatch.

Summary: Aquatic hyphomycetes play important roles in stream ecosystems, but are at risk from fungicide exposure. Fungicide exposure may lead to shifts in fungal community composition, impacting leaf decomposition. Tolerant species in mixed cultures help safeguard the decomposition process.

Summary: This study is about the metagenomic sequencing of initial fungal communities on decomposing common reed leaves under different environmental conditions. Results show that a complex network of fungi forms on the plant and persists into the decomposition phase. The geographic source of the litter and leaf age do not affect the structure and diversity of fungal communities.

Summary: Heterotrophic microbial decomposers colonize submerged leaf litter in close proximity to periphytic algae, which release labile organic carbon. The exudates from periphytic algae can either stimulate or reduce leaf litter decomposition. This study found that diatoms reduced alder decomposition and associated fungal abundance, indicating negative priming. It is suggested that alder-associated heterotrophs obtained energy from diatom exudates and channeled it to alternative pathways, potentially affecting energy and nutrient availability in the food web.

Summary: The biodiversity of litter can regulate carbon and nutrient cycling during mixed decomposition. The decomposition rates of mixed litters often deviate from those predicted for individual litter species. This study found that different carbon fractions in mixed litter responded differently to litter diversity, with soluble carbon fractions decomposing more slowly and lignin fractions decaying more quickly than expected. Furthermore, the relative mixing effects of bulk litter decomposition may be determined by the decomposition of the lignin fraction.

Summary: The study evaluated the fungal community composition during litter decomposition in areas invaded or not invaded by Tradescantia zebrina in the Atlantic Forest. The invaded sample showed higher richness and a difference in species dominance. The presence of Basidiomycota was more predominant in the non-invaded areas, indicating a difference in fungal biodiversity between the two areas.

Summary: The reasons for the higher-than-expected soil and litter faunal diversity, especially in terms of specialization of arthropod detritivores towards leaf-litter species, are still poorly understood. This study assessed soil detritivorous arthropod diversity patterns in relation to eight green leaf-litter species in an old-growth, diverse southern Afrotemperate forest. The results showed that ground-dwelling, detritivore arthropods are largely generalist towards leaf-litter species, and decomposition rates were largely independent of the diversity of detritivorous arthropods.

Summary: Research shows that under drying conditions, fungal biodiversity has a positive effect on organic matter decomposition and fungal biomass accrual; changes in fungal species composition are mainly driven by species turnover. Maintaining high levels of biodiversity is crucial for maintaining functional freshwater ecosystems in response to ongoing and future environmental changes.

Summary: Invasive signal crayfish have negative impacts on taxonomic and functional biodiversity in freshwater ecosystems. Their presence leads to a decrease in invertebrate abundance, richness, and diversity, as well as changes in community structure. Additionally, crayfish presence increases leaf litter breakdown, but this effect decreases at sites with higher crayfish abundance.

Summary: Aquatic hyphomycetes play an important role in decomposing organic matter in freshwater ecosystems. This study used the ITS rDNA barcodes database to explore their molecular diversity and distribution patterns. The findings showed an increase in the number of aquatic hyphomycete species, providing insights into their taxonomic placement and biogeographical origins. Future research should focus on expanding the ITS sequence database for species with unclear phylogenetic relationships and limited sequences.

Summary: Both gradual and extreme weather changes have complex ecological responses in river ecosystems, but the effects of trend or event changes on biodiversity and functioning are still unclear. A comprehensive analysis of 71 published studies showed that extreme changes in water flow and temperature significantly reduce species richness, while gradual changes have no such effect. Event effects, particularly those affecting hydrological dynamics, have twice the impact on biodiversity and primary productivity compared to gradual changes. Dryness associated with flow interruption has the largest impact on river biota and ecosystem functions among extreme weather events.

Summary: Fungi in intermittent rivers and ephemeral streams have different strategies and adaptations to cope with drying, but these adaptations may have trade-offs that affect ecosystem functioning. This study found that drying duration and frequency were the most influential variables in determining fungal species differentiation. The research also identified four drying niche-based groups with different responses to drying. Furthermore, the study showed that species in the drying specialist group had a weak contribution to ecosystem processes, indicating trade-offs between drying resistance and growth energy.
