Summary: This study investigates the decay potential of ectomycorrhizal (ECM) fungi on soil organic matter (SOM) and the distribution of genes associated with SOM decay in ECM fungal communities in relation to soil inorganic nitrogen availability. It was found that ECM fungal communities in low inorganic nitrogen soils are enriched with genes involved in lignin, cellulose, and chitin decay. These communities exhibit stronger SOM decay potential compared to those in high inorganic nitrogen soils.

Summary: It has been proposed that competition between ectomycorrhizal (ECM) fungi and free-living saprotrophs for resources like nitrogen (N) slows decomposition and increases the soil carbon storage in ECM ecosystems compared to arbuscular (AM) ecosystems. Theoretical modeling experiments were conducted to explore the conditions under which ECM N acquisition processes induce stronger saprotrophic N limitation and result in slower decomposition rates and greater soil organic carbon accumulation than AM processes. The results revealed that the ECM fungi more strongly inhibited decomposition when litter inputs were N-depleted and relatively recalcitrant and when ECM fungi possessed a strong capacity to mine N from both recalcitrant soil organic matter and microbial necromass. Climate and seasonality also played a role in the ECM competition effect.

Summary: This study examines the effects of changes in ectomycorrhizal fungal community structure on root colonization and seedling biomass during pine invasions. The results show that the composition and traits of ectomycorrhizal fungi vary across the landscape and have a significant impact on the success of pine invasions. Suillus spp. dominates areas without pine trees, but its success is contingent on a lack of competition with other ectomycorrhizal fungi.

Summary: Leaf anatomical traits show different patterns of variation along altitudinal gradients at species and community levels. At the species level, traits increase with altitude influenced by phylogenetic and environmental factors, while at the community level, traits first increase and then decrease with elevation mainly influenced by climatic factors. Different environmental factors and phylogenetic differences should be considered when exploring the variation in leaf anatomical traits.

Summary: The decomposition dynamics of ectomycorrhizal fungal fruit bodies in response to atmospheric nitrogen deposition vary depending on the decomposition stage. Nitrogen deposition promotes mass loss in the early decomposition stage but mitigates it in the later stage. This study highlights the importance of considering the decomposition stage when studying the ecological feedback of ectomycorrhizal fungi under nitrogen deposition.

Summary: Elevational gradients provide unique opportunities to study the role of intraspecific and interspecific trait variations in response to stress gradients. In a Mediterranean altitudinal gradient, plant traits showed different patterns with elevation, with interspecific functional variability being the most relevant component. Highest and lowest elevations were the most selective due to severe climatic conditions, while intermediate elevations were the most favorable.

Summary: Forest species can be affected by both macroclimate and microclimatic variability. In this study, we found that the fruiting community of fungi was influenced by microclimatic differences. We also discovered that tough-fleshed species were more common in harsher microclimates under open canopies. However, the responses of fruit body size and color were inconsistent across different fungal lineages. Our findings suggest that tough-fleshed fruit bodies may provide protection against microclimatic extremes by reducing dehydration. As climate change leads to increased microclimatic harshness, the presence of soft-fleshed fruit bodies is likely to decrease.

Summary: Forestry practices in Europe have had negative impacts on saproxylic diversity due to changes in tree species composition and reduction of dead-wood amount and heterogeneity. This study examined the relative importance of space and host on saproxylic diversity in Germany and found that both factors play important roles but the importance varies among different taxa. The findings suggest that a high dead-wood tree species diversity on a broad spatial coverage at the national scale is necessary to maintain rare and abundant species.

Summary: The reduction of deadwood due to forest management threatens saproxylic diversity. Deadwood types have a stronger effect on alpha- and beta-diversity than microclimate, with logs showing higher diversity for beetles and fungal fruits, and snags having high fungal diversity. Effective combinations of deadwood types and microclimate contribute to gamma-diversity.

Summary: Intensification of land use by humans has led to a homogenization of landscapes and decreasing resilience of ecosystems globally due to a loss of biodiversity, including the majority of forests. Biodiversity-ecosystem functioning (BEF) research has provided compelling evidence for a positive effect of biodiversity on ecosystem functions and services at the local (alpha-diversity) scale, but we largely lack empirical evidence on how the loss of between-patch beta-diversity affects biodiversity and multifunctionality at the landscape scale (gamma-diversity).

Summary: By analyzing 6.1 million fungal fruit body records, this study reveals the similarities and differences in fruiting events in major terrestrial biomes. While most biomes exhibit a main fruiting peak in most years, boreal and temperate biomes also have a second peak indicating spring and autumn fruiting. The timing and duration of fungal fruiting are influenced by temperature, and with global temperature increase, these biome-specific differences in fungal phenology are expected to change in space and time.

Summary: Despite the ubiquity of host-fungal symbiotic interactions, the effects of symbiosis on the ecology and evolution of fungal spores involved in dispersal and colonization have been neglected. Through a spore morphology database, we found that symbiotic status correlated with changes in spore size, but this effect varied among different fungal phyla. Symbiosis explained more variation in spore size distribution than climatic variables, and spores of plant-associated fungi have more restricted dispersal potential compared to free-living fungi. Our study advances life-history theory by highlighting the role of symbiosis in shaping reproductive and dispersal strategies among living organisms.

Summary: Because animal carcasses often serve as reservoirs for pathogens, their location and removal are crucial in controlling the spread of diseases. Recent studies have shown that infrared sensors can be used to locate animal carcasses, but little is known about the factors influencing detection success. In this study, we investigated the potential of infrared technology to locate wild boar carcasses, as they play an important role in the spread of African swine fever. Our results showed that the thermal camera accurately measured carcass temperature and that the probability of finding carcasses was influenced by environmental and carcass conditions such as habitat type, air temperature, canopy openness, and decomposition stage.

Summary: This study used bioacoustics and metabarcoding to measure forest recovery post-agriculture in a global biodiversity hotspot in Ecuador. The results showed that the composition of vocalizing vertebrates identified by experts reflected the restoration gradient, and two automated measures correlated well with restoration. Furthermore, both measures also reflected the composition of non-vocalizing nocturnal insects. This study demonstrates the effectiveness of new technologies in monitoring forest recovery.

Summary: Functional trait approaches in ecology often face challenges due to the lack of clear hypotheses about trait-niche relationships. This study investigated how different metrics affect inferences about trait-niche relationships using saproxylic beetles in fragmented Finnish forests. The results showed that community-weighted mean trait values (CWMs) were more likely than hierarchical joint species distribution models (JSDMs) to support trait-niche relationships.

Summary: In response to reports of significant insect declines, there has been an increase in the gathering and analysis of insect time series data. However, there is still disagreement regarding the reasons behind these declines. To address this issue, it is necessary to conduct experiments in addition to quantitative analysis of existing data, in order to determine the most important drivers of decline. A coordinated effort among researchers is needed to rank these drivers and generate the knowledge necessary for effective conservation action.
