    Abstract The distribution data of 18 categories (including 446 species) of bryophytes in 66 islands of the Zhoushan Archipelago, China were complied. By using the matrix temperature and the NODF metrics under six null models, we evaluated their nestedness levels and explored possible mechanisms to form nested distribution with partial Spearman correlation and the random placement model. The main results were as follows: 1) all the 18 categories of bryophytes exhibited a high degree of nestedness; 2) nestedness level was higher for mosses than liverworts, higher for acrocarpous mosses than pleurocarpous mosses, and also varied among families; 3) the nested distribution of bryophytes in the archipelago was not due to passive sampling, but mainly due to nested habitats and selective-extinction; 4) spore size might be a factor linked to selective-colonization accounting for nestedness of some bryophyte categories; and 5) nestedness level was higher for families with a high proportion of generalists than those with a high proportion of specialists, the conservation of the latter should cover more islands (patches).

    Abstract "Dalajiao" is a common variety of Phalaenopsis aphrodite . The individuals of the variety were cultured at a high temperature of 35℃, 14 h light/d with different durations. Throughout the treatment, their morphological changes were observed and the chlorophyll fluorescence parameters including the maximum quantum efficiency of photosystem II (PSⅡ) photochemistry(F v /F m ), electron transfer rate under different light intensities were determined. Their corresponding explants were cultured in vitro to evaluate the potential for successful reproduction in vitro . We found that there existed a positive correlation between F v /F m of the stems and the successful rate of tissue culture in vitro with corresponding stems. When F v /F m of stems was less than or equal to 0.35, the stems were unable to be cultured in vitro because of lacking vitality. The F v /F m of the stems is better than that of the leaves in indicating their potential as explants for tissue culture in vitro .

    Abstract There exists an obvious gap in our knowledge of the nuclear DNA amount of bryophytes, not only in terms of the low number of species represented, but also in systematic and geographic representation. In order to increase our knowledge of nuclear DNA amounts and variation patterns in bryophytes, and their potential phylogenetic significances and influences on phenotypes, we used flow cytometry to determine the DNA 1C values of 209 bryophyte accessions, which belong to 145 mosses and 18 liverworts collected from China, by using

    Methods: We investigated the species richness (SR) of five bryophyte groups (total bryophytes, total mosses, liverworts, acrocarpous mosses, and pleurocarpous mosses) and habitat types on 66 islands. By using four threshold models, the logarithmic and the power models, we quantified their SR-

    Abstract Understanding the effects of island shape and dispersal limitation on species assemblages is important for the conservation of bryophytes in fragmented landscapes. In order to explore the comparative contributions of dispersal limitation vs environmental filtering, island shape vs other island attributes to bryophyte species assemblages in fragmented landscapes, we investigated bryophyte flora and environmental variables (island shape, area, elevation, and isolation degree) of 71 islands in the Zhoushan Archipelago in the East China Sea. We used redundancy analysis, canonical correspondence analysis and generalized linear mixed models to explore comparative contributions of dispersal limitation vs environmental filtering, shape vs other explanatory variables to bryophyte species composition and species richness. Dispersal limitation independently accounted for 15% of the total variation in species composition, which was higher than environmental filtering (6.6%). When island shape was the only constraining explanatory variable, it explained 22.5% of the total species richness variation. Variance partitioning showed that island shape per se explained 3.8% of the total variation in species richness and 18.7% of the variation was confounded by island shape and other variables. Island shape combined with area and elevation was a good predictor of bryophyte species richness, independently explaining 40% of the total SR variation. Among twenty tested bryophyte categories, eighteen categories had positive relationships of their species richness with island shape irregularity, their species richness linearly increasing with island shape irregularity to varying extents. Island shape irregularity exerted a stronger effect on the species richness of acrocarpous mosses than that of pleurocarpous mosses. Therefore, dispersal limitation exerted significant effects on bryophyte species assemblages, and island shape imposed a significant and taxon-specific effect on bryophyte species richness. Our findings implied that a forest reserve with a high irregular shape is favourable for bryophyte conservation.

    Abstract 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.
