Title:	Data on lizards captured in pitfall traps at the Jornada Basin LTER site, 1989-2006
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains data on lizards sampled by pitfall traps located at 11 consumer plots at Jornada Basin LTER site from 1989-2006. The objective of this study is to observe how shifts in vegetation resulting from desertification processes in the Chihuahaun desert have changed the spatial and temporal availability of resources for consumers. Desertification changes in the Jornada Basin include changes from grass to shrub dominated communities and major soil changes. If grassland systems respond to rainfall without significant lags, but shrub systems do not, then consumer species should reflect these differences. In addition, shifts from grassland to shrubland results in greater structural heterogeneity of the habitats. We hypothesized that consumer populations, diversity, and densities of some consumers will be higher in grasslands than in shrublands and will be related to the NPP of the sites. Data on lizards captured in pitfall traps at the 11 LTER II/III consumer plots (a subset of NPP plots) were collected quarterly for 2 weeks per quarter. Variables measured include species, sex, recapture status, snout-vent length, total length, weight, and whether tail is broken or whole. This study is complete.

Description:

Methods

In conjunction with net primary production studies, consumer and faunal studies are conducted at or near NPP sites using pitfall traps. "Consumer plot" trapping grids were established in 1989 (LTER II) at three creosotebush sites, three grassland sites, and three mesquite sites, and two tarbush sites (11 of the 15 NPP sites). Each grid consisted of 4 x 4 rows of traps spaced at 15 meter intervals. Note that methods changed somewhat in 1995 at the start of 1995, and separate pitfall traps for arthropods were also established at this time. Very detailed methods that include this change are described in the attached "dsd" file listed in Additional Files below.

Each trap was 40 cm deep and contained an inner plastic container and funnel. A ceramic tile was placed over each trap to close the trap during non-sampling perions. For a 2-week period during each quarterly sample period, the tiles were raised on one side, and the traps were checked every 3 days in summer and once a week in winter. Individual lizards were taken from the traps, identified, sexed, measured, and weighed. Each lizard was clipped with a unique number using the codes on the diagram on the field data sheets. Toe clipping was done from 1989 to 1995. Starting in March 1995 toe clipping was terminated and lizards were instead marked with a black sharpie marking pen to provide a temporary mark to determine recapture status over a particular 2-week trapping period. A black mark was made posterior to the cloaca on the ventral base of the tail.

Traps were opened for two consecutive weeks every month for the period 16 June 1989 to 23 August 1991. Beginning after August 1991, traps were opened for two consecutive weeks quarterly: in February-March (following winter NPP), in May-June (following spring NPP), in August, and in October-November (following fall NPP).

Additional files

'Lizardcodelist.txt' is a text file describing the taxonomic codes identifyinglizards in the data file (by scientific and common name). The 'CODE' column should match (at least some of) the taxonomic codes in the data file.

'lizrdpit.his.txt' is a listing of notes recorded during data collection. Often they are field notes specific to a particular record in the data file. The 'pc' column in the data file references this file when its value is 1.

'lizrdpit.dsd.txt' is a metadata file created during the time of the study. It contains additional metadata that may not have been placed into the current EML file for this data package.

Additional Info

Additional Information:

Pitfall grids consist of sixten stations (four by four row grid with 15 meters between stations) located at the following 11 sites (the old code, no longer used, is given in parentheses following each site*): T-WEST (TBA), T-EAST (TBB), M-RABB-A (MDA), M-NORT (formerly M-RABB-C (MDC), moved to M-NORT in 1995), M-WELL (MDB), G-IBPE-C (GLC), G-SUMM (formerly G-IBPE-A(GLA), moved to G-SUMM in 1995), G-BASN (GLB), C-SAND (CBB), C-CALI (CBA), and C-GRAV (CBD). Pitfalls formerly located at MB (mixed basin slope NE of weather trailer) and C-SAND-C (CBC) have been closed. No pitfalls are directly associated with the following NPP sites: P-COLL, P-SMAL, P-TOBO (because of flooding potential), or T-TAYL. The pitfall for C-SAND is located NW of the NPP site (see site map). The location of each trap is marked by a rebar bearing a numbered aluminum tag.
