This data package contains the composition of foliage arthropod
trophic levels in nutrient-rich and nutrient-poor creosote bush sites
at the Jornada Basin. This data was collected for the purpose of
testing the hypothesis that creosotebush shrubs (Larrea
tridentata) growing in naturally nutrient-rich sites had
better quality foliage and supported greater populations of foliage
arthropods than shrubs growing in nutrient-poor sites. Sampling took
place in May of 1986 from random, high nutrient, and low nutrient
shrubs. Total numbers of taxa and individuals of each major trophic
group (herbivores, predators, and omnivores) from each of the 30
shrubs/sites are listed. This dataset consists of the date of
collection, plot ID, shrub type, shrub number, numbers of taxa per
shrub (grouped into chewing, sucking, predacious and omnivorous
arthropods), and numbers of individuals per shrub (grouped into
chewing, sucking, predacious and omnivorous arthropods). This dataset
is complete.
