Grasshopper survey and substrate utilization data at the Jornada Basin LTER site, 1983 to 1985

This dataset contains grasshopper occurrence observations sampled
from 9 plots on the east bajada of the Dona Ana Mountains at the
Jornada Basin LTER site from 1983 to 1985. Three plots were situated
on the bajada parallel to and 200 m south of the LTER-I transect.
Two additional sets of three plots were located 5 km and 10 km south
of the LTER transect. Each plot is composed of two 50 meter belt
transects, each divided into ten 5-square-meter quadrats.
Grasshoppers were visually sampled in each quadrat/plot, once in
May, July and September, in 1983, 1984 and 1985. Each individual
grasshopper, its age, sex and the substrate it was observed on, are
recorded as observations in the dataset. This study is complete.

本数据集收录了1983至1985年间，在霍顿盆地长期生态研究（Long-Term Ecological Research, LTER）站点多纳阿纳山脉东麓冲洪积扇的9个样地中采样得到的蝗虫出现观测记录。其中3个样地设置于与LTER-I样线平行且位于其以南200米的冲洪积扇区域；另外两组各3个样地分别位于LTER样线以南5千米和10千米处。每个样地由2条50米的带状样带（belt transect）构成，每条样带又被划分为10个5平方米的样方（quadrat）。研究人员于1983、1984、1985年的5月、7月和9月，对每个样方/样地内的蝗虫开展目视采样调查。数据集将记录每一只观测到的蝗虫的个体信息、虫龄、性别以及其所处的栖息基质。本研究数据采集工作已全部完成。
