Habitat selection/Caracolus caracolla and other snails

Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (every 0.5 m from ground level to 3 m). The files are divided because variables measured varied by year. This data set consists of 7 files. Data sets from 1991 through 1995 each have slightly different categories for measures of litter depth, canopy openness, or physical features (e.g. slope, aspect, soil type) that are not always included in later data sets. In addition, plant species recorded changed slightly over this time period, but were standardized by 1996. Various habitat characteristics are presented, as well as the apparency of common plant taxa at 7 heights (every 0.5 m from ground level to 3 m).

本数据集涵盖多项栖息地特征，以及常见植物类群在7个高度层（从地面至3米，每0.5米为一层）的显见性。本数据集因各年份测定的变量存在差异而拆分为7个数据文件。1991年至1995年的各数据集，其枯落物厚度、冠层开度或地形物理特征（如坡度、坡向、土壤类型）的测定分类略有不同，这些指标在后续数据集中并非始终保留。此外，此时间段内记录的植物物种略有变动，但至1996年已完成标准化处理。本数据集同时涵盖多项栖息地特征，以及常见植物类群在7个高度层（从地面至3米，每0.5米为一层）的显见性。本研究得到美国国家科学基金会（National Science Foundation）拨付的多项资助（BSR-8811902、DEB-9411973、DEB-9705814、DEB-0080538、DEB-0218039、DEB-0620910、DEB-1239764、DEB-1546686及DEB-1831952），由波多黎各大学承接，作为卢奎洛长期生态研究计划的一部分。本研究同时得到波多黎各大学以及美国农业部林务局国际热带森林研究所的支持。
