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.
Summarizes mean aboveground net primary production, in g/m2/yr, by year for each of 15 sites.
Daily summary values of averages of readings of the following parameters are made which are based on data recorded on a Campbell CR10(X) data logger: maximum, minimum, and average air temperature; maximum and minimum relative humidity; total preci
These data are collected to provide a measurement of rainfall at the Biodiversity site. They are Daily Summary data providing daily totals for those dates that precipitation occurred. Values are in millimeters (mm).
Data are photosynthetic rates (Amax) for leaves collected from plants subjected to five possible precipitation treatments: -80%, -50%, control (0), +50%, +80%.
Data are pre-dawn water potential for leaves collected from plants subjected to five possible precipitation treatments: -80%, -50%, control (0), +50%, +80%.
