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 2023. 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2023年期间，每年7月或8月，研究人员在佐治亚沿海生态系统（Georgia Coastal Ecosystems, GCE）长期生态研究（Long-Term Ecological Research, LTER）区域内的8个采样点开展了蚱蜢丰度与物种多样性调查。在每个采样点的中部沼泽带（mid-marsh zone）随机设置8至10条2米×10米的样线，沿样线进行目视调查。对每条样线内观察到的所有蚱蜢进行计数，并在可能的情况下鉴定至物种水平。这些调查是GCE无脊椎动物监测项目的一部分，每年开展一次，旨在评估GCE研究区域内物种相对丰度的长期变化。
