Wild bees of wooded and herbaceous semi-natural habitats

The aim was to assess the difference in bee communities in three types of wooded and herbaceous habitats (permanent grassland,hedgerow and forest edge). The bees were netted in each of these habitats,in 30 landscapes selected according to a gradient of % of woodland. Wild bees were collected in May and June 2016 using an insect net along transects in each sampling point. Bees were hunted for 10 minutes,excluding time of capture and preparation of each individual insect. The transects were 100 m long and 5 m wide and were located in the middle of grasslands and along forest edges and hedgerows.本研究旨在探究三种木本-草本生境（永久草地、树篱（hedgerow）与林缘）内的蜂类群落差异。研究选取了30个依据林地占比梯度设置的景观单元，在各生境中开展蜂类采样工作：2016年5月至6月期间，研究人员于每个采样点沿样带（transect）使用捕虫网采集野生蜂类，单次采样时长为10分钟，该时长不包含单头昆虫的捕捉操作与标本制作环节。本次采样所用样带长100米、宽5米，布设位置涵盖草地中央、林缘以及树篱带沿线。
