Effects of microclimates on species richness of epiphytic and non-epiphytic bryophytes along a subtropical elevational gradient in China

Aim: Biodiversity patterns along elevational gradients have been well documented for vascular plants and terrestrial vertebrates, but we know relatively little about the elevational patterns of bryophytes and their underlying mechanisms, especially the effect of forest microclimate on epiphytic and non-epiphytic bryophytes. Here we study the influence of microclimate variables on the richness of epiphytic and non-epiphytic species for bryophytes as a whole, and for liverworts and mosses separately, in forests along an elevational gradient ranging from 369 m to 1476 m in Mt. Tianmu, a subtropical region in eastern China.
Location: Mt. Tianmu in eastern China.
Methods: We sampled bryophytes in each of 16 vegetation plots, each in the size of 20 m by 20 m, along the elevational gradient and distinguished between mosses and liverworts and between epiphytic and non-epiphytic species. We measured climate conditions at local sites.

## Description of the data and file structure

This study was conducted in Tianmushan National Nature Reserve (TNNR). Bryophyte field surveys were carried out between April and November 2018 in TNNR. Sixteen forest plots measuring 20 m × 20 m were established along an elevational gradient ranging from 369 m to 1476 m. To obtain data on species richness in a plot as complete as possible, both plot sampling (PS) and floristic habitat sampling (FHS) methods were used in field data collection in TNNR. We investigated epiphytic bryophytes at heights of 0.3 m and 1.5 m and north-facing orientation on each tree by utilizing a subplot with a 20 cm × 20 cm metal frame quadrat containing 100 equal-sized standard grids (Figure 1) for each tree sampled. This design allowed for c...,

一、研究目的
维管植物与陆生脊椎动物沿海拔梯度的生物多样性分布模式已得到充分研究，但目前学界对苔藓植物（Bryophytes）的海拔分布模式及其内在调控机制，尤其是森林微气候对附生（epiphytic）及非附生（non-epiphytic）苔藓植物的影响，仍缺乏足够认知。本研究以中国东部亚热带区域的天目山为研究区域，选取海拔369米至1476米的森林样带，分别探究整体苔藓植物、苔类植物（Liverworts）与藓类植物（Mosses）的附生及非附生物种种丰富度对微气候变量的响应。

二、研究地点
中国东部天目山。

三、研究方法
本研究沿海拔梯度设置16块20米×20米的植被样地，对苔藓植物进行系统采样，并区分苔类与藓类植物，以及附生与非附生物种。同时对各样地的局地气候条件开展测定。沿海拔梯度的苔藓植物物种丰富度……

## 数据与文件结构说明
本研究在中国天目山国家级自然保护区（TNNR）内开展。2018年4月至11月期间，研究团队完成了该保护区内的苔藓植物野外调查工作。沿海拔369米至1476米的梯度共设置16块20米×20米的森林样地。为尽可能完整获取样地内的物种丰富度数据，野外数据采集同时采用样地采样法（Plot Sampling, PS）与植物区系生境采样法（Floristic Habitat Sampling, FHS）。针对每棵采样树木，于其0.3米及1.5米高度的北向方位，使用内含100个等大标准格网的20厘米×20厘米金属框样方（图1）开展附生苔藓植物调查。该设计可用于……
