3. Ecosystem Scope The High Plains Initiative for Integrated Phenology University of Nebraska http://csce.unl.edu/phenology/ Managed ecosystems: Crops –Can we collect data that can be used? Is there other data that we can take to make more complete data sets? –Perennials (tie to the rangeland sciences and grapes), winter annuals, spring annuals –How close is the phenology tied to time of planting; or prior weather—seed quality, fall growth? –In perennials, how is phenology affected by previous year effects; prior weather? –Can the managed ecosystems be tied unmanaged ecosystems?

Ecosystem Scope The High Plains Initiative for Integrated Phenology University of Nebraska http://csce.unl.edu/phenology/ Managed ecosystems: Crops –How can the data be used—what is the impact on agriculture and our food systems? –Is the lengthening fall as much or more a concern than the start of spring? Are there signature plants for late season—perennials, annuals, etc. –Are there end of season traits that can be used to study phenology and climate? Late flowering plant? –How do we link to models?

5. Ecosystem Scope The High Plains Initiative for Integrated Phenology University of Nebraska http://csce.unl.edu/phenology/ Unmanaged ecosystems: –Migratory birds –Grasshoppers (APHIS--those that overwinter as nymphs vs. those that overwinter as eggs). They have different feeding habits. –Wildflowers –Hessian fly/ wheat head army worm, other insects— other crops. Predator/pest cycles, etc. related to the “strength” of the winter. –Diseases (Cereal Disease Laboratory)—aerial fungi, vectored viruses. –Tie to lilac data.
