- Dataset: Ecotone Rodent Trapping 1st Capture
The purpose of the study is to investigate how pulses of precipitation translate into pulses of plant aboveground net primary productivity (NPP) and how the small mammal community responds to such changes also in relation to shrub gradient across the landscape. Particularly we are interested in how the energy flows through the ecosystem in response to pulses of rain, how the small mammal community partition resources (in terms of C3 (forbs and... more
Stocking rates for cattle, horses, and sheep are provided for the Jornada Experimental Range beginning in 1916. Goats were few and are included as part of the sheep category and not differentiated.

Introduction. Animal consumers have important roles in ecosystems (Chew 1974, 1976), determining plant species composition and structure (Harper 1969, Pacala and Crawley 1992, Crawley 1983, 1989), regulating rates of plant production and nutrient cycling (Naiman 1988, McNaughton et al. 1989, Holland et al. 1992), and altering soil structure and chemistry (Milchunas et al. 1993, Huntly 1991).
