Tuskegee_Canopy_Bee_Data

This dataset contains records of bee captures from a vertically stratified sampling study conducted in Tuskegee National Forest (Tuskegee, Alabama, USA) from April to October 2021 and March to October 2022. Blue vane traps were deployed at four forested sites, each with four replicates consisting of paired traps located in the understory (1 m) and upper canopy (average 20 m). The goal was to evaluate how native bee assemblages differ between vertical strata in a southeastern temperate deciduous forest. In total, 1,494 bees were captured, representing 38 taxa across 15 genera and five families: Andrenidae, Apidae, Colletidae, Halictidae, and Megachilidae. Each record includes sampling site, replicate, trap height (canopy or understory), date of collection, taxonomic identification, and abundance. The dataset supports findings that bee abundance, diversity, and community composition vary by vertical stratum, season, and year, highlighting the importance of stratified, long-term sampling in forested ecosystems.本数据集收录了2021年4月至10月、2022年3月至10月于美国阿拉巴马州塔斯基吉国家森林（塔斯基吉）开展的垂直分层采样研究中的蜜蜂捕获记录。研究人员在4处林地样地布设了蓝色风诱捕器（Blue vane traps），每处样地设置4组重复采样单元，每组单元包含分别设置于林下（1米高度）与林冠上层（平均20米高度）的成对诱捕器。本研究旨在探究东南温带落叶林内本土蜂类群落在不同垂直分层间的组成差异。本次研究共计捕获蜜蜂1494只，隶属于5个科、15个属、38个类群，涵盖地蜂科（Andrenidae）、蜜蜂科（Apidae）、集蜂科（Colletidae）、隧蜂科（Halictidae）及切叶蜂科（Megachilidae）。每条捕获记录均包含采样样地、重复组编号、诱捕器布设高度（林冠或林下）、采集日期、分类鉴定结果以及种群个体数量。本数据集可为“蜂类种群丰度、多样性及群落组成随垂直分层、季节与年份存在显著差异”这一研究发现提供数据支撑，同时凸显了分层长期采样在林地生态系统研究中的重要价值。
