Alternate Identifier:DOI PLACE HOLDER
Abstract:

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.

Sampling design and laboratory analysis

=======================================

This data was collected in 1986 as part of the Jornada Basin LTER program.

Five plots, approximately 1 ha in size and labeled A-E, were randomly selected from a 1.0 by 0.5 km area within a creosotebush stand. The site area was situated on a gradually sloping east-facing alluvial slope below the Dona Ana mountains. Creosotebush was the dominant shrub in the area, associated with less abundant subshrubs and a variety of small annual forbs. Thirty shrubs were selected for sampling from each of the five plots. To test for differences in foliage characteristics and arthropod densities between nutrient-rich and nutrient-poor shrubs, 10 high nutrient shrubs and 10 low nutrient shrubs were selected in each plot. Shrub nutrient status was determined on the basis of the relative size of leaf litter accumulations on the ground beneath shrub canopies. Ten shrubs were selected at random from each plot prior to selecting different shrub types in order to provide measurements of natural variability of shrub characteristics and foliage arthropods.

Foliage arthropods were sampled from each of the 150 shrubs on May 2, 1986. Three branches were selected randomly from each shrub and shaken into an insect sweep net. A consistent-sized branch of 50 cm in length was sampled each time to provide a standardized sample from each shrub, regardless of shrub size. The contents of three branch samples per shrub were combined into one zip-lock plastic storage bag and taken to the lab, frozen, and later sorted. Field sampling was done in the morning at sunrise. Arthropods were classified into trophic groups, or guilds of taxa that had similar morphological feeding mechanisms and fed on similar food resources.
