Title:Rabbit feces counts on 1m x 1m plots from the long-term Small Mammal Exclosure Study (SMES) at Jornada Basin LTER, 1995-2015
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data package contains rabbit feces count data from plots with various levels of herbivore exclusion on 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. Four replicate experimental blocks were randomly located at the grassland study site to measure vegetation responses using 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. Because grazing cattle are excluded from the entire creosote site, only three replicate experimental blocks were randomly located there including a) all mammalian herbivores, including lagomorphs, and rodents, b) lagomorphs only, and c) control accessible to all herbivores. Thirty-six sampling points were positioned at 5.8-meter intervals on a systematically located 6 by 6 point grid within each plot. A permanent one-meter by one-meter vegetation measurement quadrat is located at each of the 36 points. Each year in spring and fall from 1995-2005, the total number of rabbit feces were counted within each quadrat. After 2005, sampling frequency channged to every 5 years and data collected record only presence or absence of feces. This study is ongoing.

Methods and protocols used in the collection of this data package
Description:

Each study site is 1 km by 0.5 km in area. Four replicate experimental blocks were randomly located at each study site depending on whether the site was grazed. The blocks are all oriented on a site in an X/Y coordinate system, with the access road to each site forming the X axis. The compass orientation at the Jornada grassland site is to the north, and Jornada creosotebush site is oriented to the south. Treatments within each block include one unfenced control plot (Treatment: C; control); one plot fenced with barbed wire, hardware cloth, and poultry wire to exclude rodents, rabbits, and cattle (Treatment: R; rodent); one plot fenced only with barbed and poultry wire to exclude cattle and rabbits (Treatment: L; lagomorph); and one plot fenced with barbed wire to exclude cattle (Treatment B; bovine). Cattle exclosure plots with barbed wire occur only at the black grama grassland site where cattle were present, for a total of 4 treatment plots at each of the four grassland site blocks. There are only 3 treatment plots at each of the creosotebush site blocks because grazing is excluded from the entire creosotebush site. The treatments were randomly assigned to each of the three or four possible plots in each block independently, and their arrangements differ from block to block. Each of the plots in a replicate block is separated by 20 meters. Each plot measures 36 meters by 36 meters. Thirty-six sampling points are positioned at 5.8-meter intervals on a systematically located 6 by 6 point grid within each plot. A permanent one-meter by one-meter vegetation measurement quadrat is located at each of the 36 points. All cover values are measured from the vegetation measurement frame, which is 1 meter by 1 meter, and partitioned into a grid of 100, 10 cm by 10 cm squares.

Each year in the spring and fall from 1995-2005, total rabbit feces cover in each quadrat was counted. Each pellet was collected in a bag and summed for the total count observation. After 2005, sampling frequency changed to once every 5 years in the fall, and the sampling method changed. In all measurements after 2005, only the presence or absence of pellets (as a 1 or 0) is recorded for each quadrat instead of a count. This study is ongoing.

Field observations were recorded on micro-cassette tape recorders. Further details on measurements and data preparation can be found in the SMES vegetation quadrat protocol included with this package ("SMESvegquadprotocol.pdf"). A comment history is found in the file "JRN086_small_mammal_exclosure_quad_his.txt".

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:

JRN LTER is funded by the National Science Foundation under award DEB 2025166.
