- The EcoTrends Project: Long-Term Data Provide Ecological Insights to Scientists and Non-Scientists (S Peters, J Yao, D Peters, S Bestelmeyer) - Environmental drivers are changing at local to global scales with corresponding effects on ecological dynamics. Large amounts of data have been collected to document these changes. Much of the data remain inaccessible to a broad audience. Solutions to these environmental problems have been elusive. The EcoTrends Project is one of the first attempts to standardize, simplify, integrate, and visualize data from diverse terrestrial, aquatic, and marine ecosystems to promote understanding and synthesis by a broad audience. These data and more are available on the EcoTrends website http://www.ecotrends.info.
- Science in the Time of Big Data: What Happens When Google Meets the Jornada LTER? (D Peters, K Havstad) - “Big Data” is quickly becoming the norm in scientific research. While having a plethora of data has substantial implications for science, it is accompanied by logistical and theoretical complications. Although attention has focused on accessibility, use, and analysis of big data, advancements are also needed in the way that scientists think about and study ecological systems in order to take advantage of Big Data. Presented here is a solution for scientists to effectively utilize Big Data to advance ecology.
- Distribution of Antiherbivory Compounds in Flourensia cernua (R Estell, D James, D Anderson) -Flourensia cernua is being used as a shrub model to study the role of terpenes in intake by browsing ruminants at the Jornada Experimental Range. Tarbush consumption by small ruminants is related to leaf surface concentration of individual terpenes, but plant to plant variability in concentration is high. Our objective was to identify sources of within-plant sources of variation in leaf chemistry in an effort to minimize sample variation and optimize sampling protocols.
- How International Research Cooperation in Africa, Asia and Latin America is Benefiting U.S. Efforts to Address Land Use Change and Management (J Herrick, J Karl, B Bestelmeyer, K Havstad, et al.) - This presentation proposes the creation of a virtual (online) “Global Conservation Assessment Project” supported by a Global Sustainable Land Management System. It includes examples of how USDA scientists are working with others around the world to develop innovative land management and monitoring systems that will help meet the challenge of feeding 9 billion people by 2050. The final slide includes a list of publications (available on this website) that provide more information on these proposals.
- Long-term Studies Provide Insights to Diverse Terrestrial and Aquatic Ecosystem Dynamics (J Yao, D Peters) - Environmental drivers are changing at local to global scales with corresponding effects on ecological dynamics. Large amounts of data have been collected to document these changes. However, much of the data remain inaccessible to a broad audience. Therefore, solutions to these environmental problems have been elusive. The EcoTrends Project is one of the first attempts to standardize, simplify, integrate, and visualize data from diverse terrestrial, aquatic, and marine ecosystems to promote understanding and synthesis by a broad audience.
- Tools to Study and Manage Grazing Behavior at Multiple Scales to Enhance the Sustainability of Livestock Production Systems (D Anderson) - No single tool exists to answer all questions, complex tools require sophisticated teams, tools should foster low stress animal handling, use tools that capitalize on innate animal behavior.
