Title:	Nematode abundance from soil cores collected beneath Mesquite trees in irrigated and non-irrigated plots at the Jornada Basin LTER site, 1988
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains nematode abundance from mesquite habitat soils at the Jornada Experimental Range (JER) during the early years of Jornada Basin LTER (LTER-I and II). The purpose of this study was to quantify nematode functional groups in soils beneath mesquite (Prosopis glandulosa). The samples were taken from irrigated and non-irrigated (control) mesquite dune habitats. 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:

Investigation of nematode abundances beneath mesquite trees (Prosopis glandulosa) began in March 1988. Soil cores were sampled from irrigated and non-rrigated coppice mesquite dune habitats. 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.

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).
