Long Term Agroecosystem Research Overview
- Agroecosystem productivity is sustainably enhanced by the development and application of new technologies
- Mitigation and adaptation of agroecosystems to climate change is improved by more accurate predictions of resource responses to system drivers
- Stronger linkages to other long-term research networks improves conservation and environmental quality in agricultural landscapes
- The socio-economic viability of, and opportunities for, rural communities are enhanced through educational outreach by LTAR scientists and collaborators
LTAR Research Sites
Data from the following LTAR sites are presented. They are related to topics such as agricultural sustainability, climate change, ecosystem services, and natural resource conservation at the watershed or landscape scale.
These data are collected to provide a measurement of rainfall at the Biodiversity site.
Line intercept data of long-term vegetation responses to shrub removal and lagomorph exclusion in a creosotebush community
The purpose of this study is to quantify vegetation dynamics in response to lagomorph and shrub exclusion. Data consist of vertical line intercept measures of the perennial grasses, suffretescents and shrubs.
This data set is comprised of daily precipitation totals, in inches, measured by Belfort Instruments weighing rain gauges at 58 locations on the Jornada Experimental Range.
The Effects of Changing Vegetative Composition on the Abundance, Species Diversity and Activity of Birds in the Chihuahuan Desert
A variety of mechanisms, both anthropogenic and natural, can lead to changes in the vegetation composition of a community. In semi- desert grasslands, for example, Schlesinger et al.
Objectives. Desertification is hypothesized to have altered the spatial and temporal availability of resources required by the biota. Results of desertification on the Jornada include changes to shrub dominated communities and major soil changes.
