Aim The species–area relationship (SAR) and the small‐island effect (SIE) are of important ecological significance. However, few studies have focused on these topics in regard to bryophytes. We aimed to (1) determine whether SIEs and a SAR with two thresholds and three different processes of species addition exist for bryophytes across continental islands and (2) test whether the SIE threshold tends to be high for stenoecious species with a high sensitivity to habitats and for those with relatively high resource requirements and low dispersal abilities. Location The Zhoushan Archipelago, China. Taxon Bryophytes. Methods We obtained species number data for five bryophyte categories (total bryophytes, total mosses, acrocarpous mosses, pleurocarpous mosses and liverworts) from 66 continental islands of the archipelago and analysed the dataset using 24 SAR models. According to Akaike's information criterion, we identified models suitable for revealing SARs and detecting SIEs among the five bryophyte categories. Results The power model was best for fitting SARs of all bryophyte categories except for pleurocarpous mosses. For detecting SIEs, the three‐segmented model provided the best support for the five categories. There were obvious SIEs for the five bryophyte groups, with area thresholds of 0.11–1.42 km2. The SIE threshold was much higher in liverworts than in mosses and in pleurocarpous mosses than in acrocarpous mosses. The second thresholds for the five categories were similar, ranging from 53.62 to 73.19 km2. Main conclusions A unique SAR pattern with two area thresholds and three different dominant processes of species addition with island area was found for bryophytes across the continental islands. The second thresholds were not due to in situ speciation but were likely due to the high immigration of bryophytes from the mainland attributed to local residents. The SIE thresholds detected for the different categories of bryophytes indicated that the values tended to be low for species groups with low resource requirements and high dispersal abilities and high for those with a high sensitivity to habitat conditions, the latter indicating that areas for conservation purposes for species sensitive to habitats should be comparatively large.

Background: Detecting nestedness distribution and understanding their origin are important for biological conservation. Although previous studies on nestedness covered a wide range of taxa, discrepancies still exist on the prevalence of nestedness among biotas, and on the mechanisms to form nested distribution. Because bryophytes are poikilohydric, highly sensitive to habitats, and have a long-distance dispersal capacity, together with the fact that continental islands highly varied in area, elevation and habitat types, bryophytes on continental archipelago are thus an ideal system for the settlement of relevant disputes on nested distribution. However, few studies have been conducted on nestedness of bryophytes. To quantify nestedness level of different bryophyte categories on continental islands and possible mechanisms, we complied a presence/absence matrix of 446 species of bryophytes in 66 islands of the Zhoushan Archipelago, China. We also recorded spore sizes of 319 moss species based on available literature. By using the matrix temperature and the NODF metrics, as well as a conservative null model, we evaluated the nestedness levels of 18 bryophyte categories. We further explored possible mechanisms to form nested distribution by using partial Spearman rank correlations based on island area, elevation, habitat types and spore size of moss species. Results : We found that all 18 categories of bryophytes exhibited a high degree of nestedness. Nestedness level was higher for mosses than liverworts, higher for acrocarpous mosses than pleurocarpous mosses，and varied among different bryophyte 13 families. The nested distribution of bryophytes in the archipelago was not due to passive sampling, but mainly due to nested habitats and selective-extinction. Spore size might be a factor linked to selective-colonization accounting for nestedness of some moss categories. Conclusions : Nested habitats, selective-extinction, and partial selective-colonization resulted in a high level of nestedness for bryophytes in continental islands. Although the nestedness of bryophyte distribution in the Zhoushan Archipelago was statistically significant, such a nestedness was not perfect. Conservation of bryophytes should not only focus on the species-richest islands.

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.
