“…As we analyzed that AI, Bio13, Bio16, and Bio18 were all closely correlated with annual precipitation, Bio4, and Bio7 were correlated with annual mean temperature tightly. These results reflect that epiphyllous liverworts favor habitats with humid and warm climate, which is consistent with past ecological studies on epiphyllous liverworts (Benavides & Sastre‐De Jesus, ; Jiang et al., ; Kraichak, ; Olarinmoye, ). These areas with humid and warm climate determine the geographical distribution of evergreen forests in China, which occur between 18 and 32°N and 98–123°E, within areas dominated by tropical and subtropical climate, with annual mean temperature between 14°C and 26°C, and precipitation ranging from 1,000 to 5,000 mm (Wu, ).…”

Epiphyllous liverworts form a special group of bryophytes that primarily grow on the leaves of understory vascular plants in tropical and subtropical evergreen broadleaf forests. Being sensitive to moisture and temperature changes, epiphyllous liverworts are often considered to be good indicators of climate change and forest degradation. However, they are a poorly collected and taxonomically complicated group, with an only partly identified distribution pattern. In this study, we built four models based on 24 environmental variables at four different spatial resolutions (i.e., 1 km, 5 km, 10 km, and 15 km) to predict the past distribution of epiphyllous liverworts in China, using Maxent model and 63 historical location records (i.e., presence‐only data). Both area under the curve of the receiver operating characteristic (AUC) and true skill statistic (TSS) methods are used to assess the model performance. Results showed that the model with the predictors at a 15‐km resolution achieved the highest predictive accuracy (AUC=0.946; TSS=0.880), although there was no statistically significant difference between the four models (p > 0.05). The most significant environmental variables included aridity, annual precipitation, precipitation of wettest month, precipitation of wettest quarter, and precipitation of warmest quarter, annual mean NDVI, and minimum NDVI. The predicted suitable areas for epiphyllous liverworts were mainly located in the south of Yangtze River and seldom exceed 35°N, which were consistent with the museum and herbarium records, as well as the historical records in scientific literatures. Our study further demonstrated the value of historical data to ecological and evolutionary studies.

“…The development of epiphyllous liverwort studies dates back to the late 18th century (Massart, 1898). They are a poorly collected and taxonomically complicated group, with an only partly identified distribution pattern (Benavides and Sastre-De Jesus, 2011). According to Pócs (1996), the distribution of epiphyllous liverworts extends into 21 floristic regions in Asia, Australia, Africa, Central and South America, and the Macaronesian islands in Europe, with Asia having the highest diversity with more than 500 known species.…”

“…Despite their ecological constraints, epiphyll communities are globally highly diverse (Benavides & Sastre-De Jésus, 2011;Lücking, 1999;Pócs, 1978;Sonnleitner et al, 2009;Verholt, 2012;Winkler, 1970;Zartman, 2003;Zhu & Ling So, 2001). The focal phorophyte of this study, as well, harbours an exceptionally high taxonomic richness begging the question as to what mechanisms contribute to maintaining so many species on such a spatially isolated and highly ephemeral substrate?…”

Understanding the mechanisms underlying species assembly is a central focus of plant ecology and is crucial to revealing how plant communities are structured. However, the temporal limitations of most terrestrial plant communities preclude collection of species assembly data in a tractable time‐frame. The aim of this study is to investigate the importance of dispersal potential, as estimated by interspecific variation in sexual and asexual expression, as a predictor of patch chronosequence assembly for epiphyllous (leaf‐inhabiting) bryophytes. Secondarily, we investigate whether spatiotemporal patterns in patch turnover and compositional variation infer evidence of local (within‐patch) population processes. The frequency and distribution of 55 epiphyllous bryophytes across five leaf age classes were studied on an understorey shrub Piper grande (Piperaceae) in premontane Panamanian tropical forest. Logistical models were used to test whether interspecific variation in dispersal‐related life‐history traits predicts assembly order. Beta diversity and ordination analyses were employed to examine nestedness vs. turnover, and probe for repeatable patterns in patch chronosequence assembly, respectively. Our results emphasize the importance of dispersal potential on species assembly patterns as earlier arrivals exhibit greater probabilities of sexual and specialized asexual expression. High turnover coupled with temporal convergence in species composition also points to evidence of within‐patch biotic filtering. Synthesis. Epiphylls are locally diverse in humid tropical forests worldwide; however, the mechanisms which maintain their high local diversity are unknown. This study suggests that interspecific variation in dispersal capacity in combination with diffuse indirect effects is the principal contributor to the high alpha‐diversity of these ephemeral metacommunities.
