Little is known about the effect of dual mycorrhization status on the hosts' global distribution and acclimation to specific environments. This study investigates the potential advantage of dual associations of more than 400 woody genera spread at a global scale. We found that dual-host woody species occupy a broader geographical range and environmental niche space compared to those associating exclusively with either AM or EM. We show that the increased geographic range and expanded environmental niche space are independent of the phylogenetic architecture and evolutionary history of the woody genera.

Using long-term annual count (number of adults captured), adult survival and productivity (number of juveniles captured per adult) data for breeding land-birds at ringing sites across Europe, we show that synchrony is strongest and largest scale in productivity and weakest and smallest scale in counts. However, counts fluctuate more synchronously with survival than they do with productivity. These patterns hold for species which do not migrate or only migrate within Europe (European-residents) and those migrating to sub-Saharan Africa (subSaharan-migrants), but the periodicity of productivity and survival synchrony is longer in European-residents than in subSaharan-migrants.

Our analyses demonstrate that prevailing windflow patterns exhibit a significantly stronger signal on fungal community structure than do geographic distances amongst sites. Notably, the signature of wind was detectable for mushrooms and fungi producing primarily wind-dispersed spores. Contrastingly, fungi primarily reliant on animal dispersal exhibited a strong signature of geographic distance but not wind-connectivity.

Here we present results from an 8-year (2014–2022) wetland warming experiment in the Yellow River Delta, revealing that wetland SOC storage responds to warming in a phase-dependent manner. We found that warming initially reduced both carbon input and output but did not change SOC storage. However, SOC storage abruptly decreased by 21.4% in 2020, which persisted over the following 2 years. This occurred mainly due to shifts in the biomass of dominant plant species (<i>P. australis</i>) under warming, reducing carbon input, increasing microbial carbon degradation, and resulting in microbial necromass carbon loss.
