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. Lizards were captured in pitfall traps at the 11 LTER II/III consumer plots (a subset of NPP plots) 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 the Jornada net primary production studies, consumer and faunal studies were 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. Two of the lizard pitfall grids were discontinued (G-IBPE-A and M-RABB-C), and new grids were established (G-SUMM, M-NORT). Very detailed methods that include this change are described in the attached "dsd" file and others listed under 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 measurements), in May-June (following spring NPP), in August, and in October-November (following fall NPP).

Note that arthropods were collected concurrently with this study, first in the same traps from 1988-1994 (knb-lter-jrn.210008002), and then in a separate grid of pitfall traps from 1996-2001 (knb-lter-jrn.210008001).

Notes about the data

In early years of the study, there were multiple pitfall grids at some NPP sitesthat are distinguished by Plot identifiers, and there no pitfall grids at other NPP sites. In 1995, the pitfall grids at M-RABB Plot C and G-IBPE Plot A sites were discontinued and new grids were established at two additional NPP sites, M-NORT and G-SUMM. Also included in this dataset are observations from one additional pitfall grid called C-SAND Plot C that was discontinued in 1997, and from an unknown location (plot values = NA) associated with the M-RABB site (possibly identified as Plot B or BB). It may be advisable to remove these observations from analysis.

The species code column (spp) includes a few codes not included in the original list of lizard species in 'Lizardcodelist.txt'. The NONE code signifies that an observation was made at the pitfall trap, but it was not of a lizard or other species (usually flooding or other problems). SOSE and BUDE codes probably stand for Sonora semiannulata (ground snake) and Bufo debilis (green toad), respectively.

Finally, note that the recapture marking method changed in 1995 from toe clipping to using marking pens. This change is detailed in some of the additional files listed below.

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.

'pitfall.pro.txt' is a detailed sampling protocol. It applies to early arthropod and lizard collections during this project.

'LizardPro.pdf' is another detailed protocol. It was written after the 1995 changes to the experimental design and is specific to lizards.

Abstract:

The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing climate and land use.

Funding:

At the time of this study, JRN LTER was funded by the National Science Foundation under award DEB 9411971.
