Long-term mid-marsh grasshopper abundance and species diversity at eight GCE-LTER sampling sites

Grasshopper abundance and species diversity were investigated at eight sampling sites within the Georgia Coastal Ecosystems (GCE) LTER study area during July or August from 2000 to 2016. Visual surveys were conducted along 8-10 2m by 10m transects randomly allocated within the mid-marsh zone at each site. All grasshoppers observed within each transect were counted and identified to species, if possible. These surveys were conducted as part of the GCE invertebrate monitoring program, and are performed annually to assess long-term changes in relative species abundances across the GCE study area.

2000年至2016年每年的7月或8月，研究人员于佐治亚海岸生态系统（Georgia Coastal Ecosystems, GCE）长期生态研究（Long-Term Ecological Research, LTER）区域内的8个采样点，开展了蝗虫种群数量与物种多样性调查。针对每个采样点的中潮滩区域，随机布设8~10条2米×10米的样带，沿样带开展目视调查。对每条样带内观测到的全部蝗虫进行计数，若条件允许则鉴定至物种水平。本调查作为GCE无脊椎动物监测计划的组成部分，每年例行开展，用于评估GCE研究区域内蝗虫物种相对丰度的长期变化趋势。
