    ----------------------------------------------------------------
    Desert grasshopper assemblages from sites in the Chihuahuan
    desert were assessed for guilds on the basis of substrate or
    microhabitat use and morphological characteristics of component
    species.  These study area had 9 separate sites on the
    east bajada  of  the Dona  Ana Mts.  The sites were arranged in 3
    X 3 configurations across a bajada so that the bajada represented
    an environmental gradient with varying soil and vegeation
    characteristics from top to bottom. Three plots were situated on
    the bajada parallel to and 200 m south of the LTER 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  m
    belt  transects,  each  divided into ten 5  m2  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  substrate it was
    observed on, are recorded.
