Plants metacommunity from temporary ponds

The database comprises a long-term survey of a plant metacommunity of
temporary ponds. The metacommunity is located in a flat landscape
surrounded by hills, where a maximum of 61 ponds, every year, are filled
with water in winter and dry out in summer in the same spatial locations.
Information on species occurrences at the sampling unit level was recorded
since 2005 (until 2022 and continuous).  The database
includes:  Species occurrences at the sampling unit level for 61
temporary ponds along 14 years (to be periodically updated). 
Species traits database and functional description of traits. 
Environmental information of each pond including connectivity, area,
heterogeneity and hydroperiod.

该数据库包含一项针对临时池塘植物集合群落（plant metacommunity）的长期调查研究。该集合群落坐落于被丘陵环绕的平坦地貌中，每年冬季最多有61个池塘在固定空间位置充水，夏季则逐渐干涸。自2005年起（截至2022年，且调查仍在持续进行），研究人员已记录了采样单元（sampling unit）尺度下的物种出现数据。本数据库涵盖以下内容：1. 历时14年的61个临时池塘在采样单元尺度下的物种出现数据（该数据集将定期更新）；2. 物种性状数据库及其性状功能描述；3. 各池塘的环境信息，涵盖连通性、面积、生境异质性以及水文周期（hydroperiod）。
