 9) Informative abstract (Describe research project completely.
    Include project OBJECTIVES/HYPOTHESIS.)
    ----------------------------------------------------------------
    *We conducted a field study to test the hypothesis that creosotebush
    (Larrea tridentata) shrubs growing in naturally nutrient-rich sites
    had better quality foliage and supported greater populations of
    foliage arthropods than shrubs growing in nutrient-poor sites.

    This is data for foliage arthropods sampled from LVAR creosotebush
    shrubs.  Sampling  was  done  in April of 1985 and 1986. Shrubs
    were sampled from 5 separate sites designated A-E.  10 shrubs
    of 3 different types, R=random, H=high quality, L=low quality
    were sampled at each site.  Total numbers of taxa and
    individuals of each major trophic group (herbivores, predators,
    omnivores), as well as total  numbers  of  individuals  of each of
    the  common  species  of  foliage arthropods, from each of the 30
    shrubs/site are listed.
