Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains nematode abundance in soils subjected to an irrigation experiment in mesquite coppice dune habitats during the early years of Jornada Basin LTER (LTER-I and II). The purpose of this study was to quantify total nematode abundance, and the abundance of nematode functional groups, in irrigated and non-irrigated (control) soils beneath mesquite plants (Prosopis glandulosa). Soil cores were taken from three depths (0-50cm, 50-100cm, and 100-150cm) then divided into subsamples for nematode investigation. Nematodes were quantified via a semi-automatic elutriator with sugar flotation-sieving and the Baerman Funnel technique. Nematodes were counted and separated into trophic groups: fungal feeders, bacterial feeders, plant parasites, and omnivore-predators. The data collection began in March 1988 and ended in October 1988. This dataset is complete.

Description:

Irrigation treatment and soil sampling:

Investigation of nematode abundances beneath mesquite trees (Prosopis glandulosa) and responses to irrigation began in March 1988. Soil cores were sampled from irrigated and non-rrigated coppice mesquite dune habitats with 30% vegetation cover and scattered shrubs of saltbush and snakeweed.

Five mesquite dunes were irrigated by pumping water from a storage tank located 200 m from the site. Water was applied to the dunes with an overhead sprinkler (later replaced by a drip irrigation system to minimize wind drift) placed at the apex of each dune. Irrigation began in March with approximately 2.5 cm applied 2-3 times/week for 6 weeks to initially wet the dry soil. Thereafter high- water availability was maintained by weekly irrigation. Five non-irrigated dunes served as control. Soil samples were collected (hand augered) under mesquite (Prosopis glandulosa) trees to three depths, 0-50 and 50-100, and 100-150cm. Soil samples were placed in plastic bags, tied, and stored in portable coolers. These samples were later divided into subsamples for nematode investigations.

Laboratory analyses:

Nematodes were recovered using semi-automatic elutriator with sugar flotation-sieving (Byrd et al. 1976), and Baerman Funnel Technique (Freckman and Virginia 1989). Nematodes were counted per kilogram of soil and separated into trophic groups (Freckman et al. 1987, Freckman and Baldwin 1990).
