Fall 2001 grasshopper monitoring -- 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 in August 2001. Visual surveys were conducted along 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. This survey was conducted as part of the GCE invertebrate monitoring program, and will be performed annually to assess long-term changes in relative species abundances across the GCE study area.2001年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，开展了蝗虫种群丰度与物种多样性调查。各采样点均在沼泽中部区域内随机布设10条2m×10m的样带，沿样带开展目视调查。若条件允许，对每条样带内观测到的全部蝗虫进行计数并鉴定至物种水平。本次调查系GCE无脊椎动物监测计划的组成部分，后续将每年定期开展，以评估GCE研究区域内物种相对丰度的长期动态变化。
