Title:	Rodent data from trapping webs in the long-term Small Mammal Exclusion Study (SMES) at Jornada Basin LTER, 1995-2007
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	This data package contains rodent trapping data from plots with various levels of herbivore exclusion on the Jornada Experimental Range (JER) and Chihuahuan Desert Rangeland Research Center (CDRRC) lands. Study sites were established in 1995; one in black grama grassland and the other in creosotebush shrubland to compare the impact of herbivores on ecosystem processes between these vegetation types. Parallel studies were established at the Sevilleta LTER site (New Mexico, USA) and Mapimi Biosphere Reserve (Durango, Mexico). Each study site is 1 km by 0.5 km in area. Three replicate rodent trapping webs and four replicate experimental blocks were randomly located at each study site. Rodent trapping webs were used to measure rodent population density and species diversity over time, while the experimental blocks measure vegetation responses to herbivore exclusion treatments including a) all mammalian herbivores, including cattle, lagomorphs, and rodents, b) lagomorphs and cattle only, c) cattle only, and d) control accessible to all herbivores. Rodent populations were sampled from each of the three webs at each study site during overnight trapping campaigns twice per year, in the early (April-May) and late (September-October) summer between 1995 and 2007 (trapping study terminated after October 2007). During each trapping campaign, live-traps were left open for three consecutive nights, and captured animals were recorded on the three subsequent mornings. Each animal caught was identified, measured, and released at the same location where it was captured. This study is complete.

Methods and protocols used in the collection of this data package

Description:

Each Small Mammal Exclusion Study (SMES) site is 1 km by 0.5 km in area. Three rodent trapping webs were randomly located near the replicate experimental blocks (3 in the creosotebush site, 4 in the grassland). Trapping webs measure small mammal diversity and density, while the experimental blocks exclude these herbivores to measure vegetation responses to the exclusion of small mammals. See the SMES quadrat data packages for further details on the design and treatments of experimental blocks.

Rodent trapping webs were used to determine the composition of rodent species at each study site, and to estimate densities of each species over time. Each rodent trapping web consists of a series of 12 equally spaced lines radiating from a central point. Each line consists of 12 trap stations. The first trap station is located 5 meters from the center, the next three at 5 meter intervals, and the remaining 8 at ten meter intervals. Each trap line is 100 meters long, and each web is 200 meters in diameter. The above rodent trapping web design has been used for many years at the Sevilleta LTER, and has been adopted by the US Centers for Disease Control and Prevention, as a standard technique for monitoring rodent populations.

Rodent populations were sampled from all three webs at each study site twice per year, in the early (April-May) and late (September-October) summer. Sherman (H. B. Sherman Traps, Inc., Tallahassee, FL) live-traps were left open for three consecutive nights, and captured animals were recorded on the three subsequent mornings. Each animal caught was identified, measured, and released at the same location where it was captured. Each animal was temporarily marked with a marking pen to determine recapture status for a given three-night sampling period. No permanent marking techniques were used. Rodent trapping was conducted at all 3 webs at each site over the same 3 night period.

Data was collected from 1995-2007. This study is complete.

Additional Information:
	The Sevilleta LTER site is located at the US Fish and Wildlife Service, Sevilleta National Wildlife Refuge in central New Mexico (Figure 1). The Sevilleta is located at 34 north latitude, and the grasslands and shrublands are at about 1,550 meters in elevation. The grassland and shrubland areas have long- term mean annual precipitation of about 280 mm and mean annual temperature of about 13 C. The Sevilleta is predominantly black grama (Bouteloua eriopoda) and blue grama (Bouteloua gracilis) grassland, with less extensive creosotebush shrub communities. The Jornada LTER site is located at the US Department of Agriculture, Agricultural Research Service, Jornada Experimental Range in southern New Mexico (Figure 1). The Jornada is located at 32 north latitude, and the grasslands and shrublands are at about 1,300 meters elevation. The long-term mean annual precipitation is 230 mm, and the mean annual temperature is 15 C. The Jornada is primarily creosotebush and mesquite (Prosopis glandulosa) shrubland with less extensive black grama grass communities. The grassland site is one kilometer west of the IBPE grassland site, and the creosotebush site is three kilo- meters southeast of the lower trailer. The Mapimi Biosphere Reserve is located in the south-central Chihuahuan Desert in the northeastern portion of the state of Durango, Mexico (Figure 1). The Mapimi site is located at 27 north latitude, and the creosotebush shrublands are at 1,100 meters elevation. Mapimi has a long-term mean annual precipitation of 271 mm, and the average annual temperature is 21C. The Mapimi research site is primarily creosotebush shrubland with mesquite. Tabosa (Hilaria mutica) grasslands occur in the bottoms of basins.
