“…During the analysis for each area, a GDM with all 152 environmental variables was fitted first. Then only the variables considered important by the first GDM were selected for the second GDM, and the outcomes of the second GDM of each area were the final result focused on here (Eslami et al, 2021). The variables considered important by the second GDM were seen as drivers of bumblebees' biodiversity.…”

“…Previously, climate, land cover and topography were considered as factors of the bumblebee composition (Naeem et al, 2019;Wang et al, 2018;Williams et al, 2015). The effects of habitat heterogeneity and soil on the bumblebee had not been reported, but their effects on other insects were revealed (Eslami et al, 2021;Wang, 2021). To assess environmental factors affecting bumblebees' biodiversity as effectively and comprehensively as possible, all these five environmental factors, including 152 variables in total, were considered in this study.…”

“…To discover environmental drivers responsible for the spatial variation of biodiversity on the plateaus is the first step towards developing appropriate management strategies (Eslami et al, 2021). Although some environmental variables may not directly affect bumblebees, they affect the food-plant nectar and pollen production, and foraging opportunities, then affect the bumblebee composition (Williams et al, 2015).…”

1. Bumblebees show a series of advantages over other pollinating insects in offering pollination services for both the ecosystem and agricultural production, especially in high-altitude areas. With climate warming, their diversity at high altitudes will be threatened. Therefore, more attention should be paid to the management of bumblebee resources at high altitudes to prevent their decline here. Discovering drivers responsible for the spatial variation of biodiversity is a benefit for developing appropriate management.2. Here, based on the bumblebee diversity on three plateau areas with an altitude gradient, the roles of different environmental factors, the climate, land cover, topography, habitat heterogeneity and soil, in the bumblebee composition were assessed by generalised dissimilarity modelling. And the relative importance of variables was evaluated by the impact on the magnitude of total biological change and the per cent change in deviance explained by models.3. According to the results, in the low-altitude area, the climate played a vital role and the most important variable was the climate variable. Then, with the altitude rising, the effect of land cover continually increased. In the medium-altitude area, the effects of different factors were detected to be similar, and the most important variables were a climate variable and a land cover variable. In the high-altitude area, land cover finally replaced the climate as the most important factor, and one land cover variable was assessed as the most important variable. Our study revealed that the relative importance of different environmental factors on the biodiversity of bumblebees can differ as the altitude rises.

“…Jaccard distance coefficient could reveal the dissimilarity between each pair of patches (islands) based on the presence/absence data of species; thus, the coefficient is a measure of beta diversity (Zhong et al 2021). The Jaccard distance coefficient was calculated as follows (Barzoki et al, 2021):

\mathrm{JD}=1-C/\left(A+B+C\right).

To explore the taxon‐dependent contribution of dispersal limitation versus environmental filters to bryophyte assemblages. We investigated bryophytes and six environmental variables on 168 islands in the Thousand Island Lake,China. We compared the observed beta diversity with the expected values based on six null models (EE, EF, FE, FF, PE, and PF), detected the partial correlation of beta diversity with geographical distances. We quantified the contributions of spatial versus environmental variables and island isolation per se to species composition (SC) using variance partitioning. We modeled the species‐area relationships (SARs) for bryophytes and the other eight biotas. To explore the taxon‐dependent effects of spatial versus environmental filters on bryophytes, 16 taxa including five categories (total bryophytes, total mosses, liverworts, acrocarpous, and pleurocarpous mosses) and 11 species‐richest families were included in the analyses. The observed beta diversity values were significantly different from the predicted values for all 16 taxa. For all five categories, the observed partial correlations between beta diversity and geographical distance after controlling environmental effects were not only positive, but also significantly different from the predicted values based on the null models. Spatial eigenvectors are more important in shaping SC than environmental variables for all 16 taxa except Brachytheciaceae and Anomodontaceae. Spatial eigenvectors contributed more to SC variation in liverworts than in mosses and in pleurocarpous mosses than in acrocarpous mosses. The effects of island isolation on SC were significant for all five categories, highly varied at the family level. The z values of the SARs for the five bryophyte categories were all larger than those of the other eight biotas. In subtropical fragmented forests, dispersal limitation exerted significant, taxon‐dependent effects on bryophyte assemblages. It was dispersal limitation rather than environmental filtering that predominantly regulated the SC patterns of bryophytes.
