Bee species abundance and composition in three ecosystem types at the Sevilleta National Wildlife Refuge, New Mexico, USA

This study was designed to examine community- or population-level fluctuations in bee species at the Sevilleta National Wildlife Refuge, both intra- and inter-annually. From 2002 to 2019, passive funnel traps were used to collect bees at three sites, each representing a different ecosystem type of the southwestern U.S. (Plains grassland, Chihuahuan Desert grassland, and Chihuahuan Desert shrubland). Bees were collected during each month from March through October, and were identified to species by taxonomic experts.本研究旨在探究塞维利塔国家野生动物保护区（Sevilleta National Wildlife Refuge）内蜂类物种在群落或种群层面的年度内与年度间波动情况。2002年至2019年间，研究人员借助被动漏斗诱捕器（passive funnel traps），在美国西南部三类不同生态系统类型的三个采样点采集蜂类样本，这三类生态系统分别为平原草原、奇瓦瓦沙漠草原以及奇瓦瓦沙漠灌丛。采样工作于每年3月至10月的每月开展，采集所得蜂类均由分类学专家鉴定至物种水平。
