International Association for Landscape Ecology

The annual meeting of the U.S. Chapter of the International Association for Landscape Ecology (US-IALE) occurred April 9-13 in Tucson, AZ. Drs. Geoff Henebry and Mike Wimberly attended the meeting to present results of their research. Dr. Wimberly presented on behalf of his co-authors Dr. Mark Cochrane, geospatial analyst Adam Baer, graduate student Kari Pabst, and Dr. Zhi-Liang Zhu, a poster entitled Fuel treatment effectiveness in the United States. Dr. Wimberly also served as chair for the session entitled Species Distributions: Populations. Dr. Henebry organized and chaired a special session entitled Phenologies as Integrative Phenomena for Landscape Research and in that session he presented a talk entitled Monitoring the phenologies of vegetation moisture using cooler earthlight.

Phenology across LTER: 2/26-3/2/2007

Phenology is the study of the timing, variability, and change in recurring biological events. Familiar examples of phenological events include the onset of spring growth and the autumnal leaf fall, the migrations of birds and butterflies, and the flowering and fruiting in wildflowers, trees, and crops.   During February 26 to March 2, Geoff Henebry organized and led a workshop entitled "Phenology across LTER" at the University of New Mexico's Sevilleta Field Station located in the 100,000 ha Sevilleta National Wildlife Refuge. LTER stands for Long-Term Ecological Research, a network of sites funded by the National Science Foundation (NSF) to understand how ecological processes vary and respond to environmental change through many years. The workshop gathered a small group of scientists from South Dakota, Puerto Rico, Oregon, New Mexico, Massachusetts, and Arizona representing seven LTER sites to evaluate the status of ongoing and prior phenological research in the LTER network, initiate a synthesis of a subset of these dataset, and formulate recommendations about how the LTER network can facilitate phenological research and interact with the emerging National Phenology Network. This workshop was funded by the NSF LTER Network Office as a follow-on event to a phenology working group at the 2006 LTER All Scientists Meeting that occurred last September in Estes Park, Colorado.

GIScCE scientists present research at the American Geophysical Union’s Fall Meeting, December 11-15, 2006, San Francisco, CA.

Drs. Geoff Henebry and Gabriel Senay, geospatial analyst Marcela Doubková, and doctoral student Valeriy Kovalskyy will be among 12,000 scientists attending the 2006 AGU Fall Meeting.

Gabriel Senay’s research will be presented in two posters in a Wednesday special session entitled Thermal Remote Sensing Data for Earth Science Research: The Critical Need for Continued Data Collection and Development of Future Thermal Satellite Sensors.

  • Senay, G.B., M.E. Budde, and J.P. Verdin: Using MODIS thermal data for estimating actual evapotranspiration from irrigated fields.
  • Budde, M.E., G.B. Senay, J.P. Verdin, and J.D. Rowland: Validation of a simplified energy balance model for estimating irrigated cropland and water use in Afghanistan.

For the third consecutive year, Geoff Henebry has convened at the Fall AGU Meeting a special session with a phenological theme. This year’s session entitled Land Surface Phenology, Seasonality, and the Water Cycle was co-organized by Mark Friedl of Boston University and Mike White of Utah State University. The Wednesday session includes 4 invited talks, 8 contributed talks, and 30 posters.


  • Henebry, G.M., and M. Doubková: Complex land surface phenologies of moisture status.
  • Keydan, G.P., A.A. Gitelson, and G.M. Henebry: Land surface phenology: which biophysical characteristics of vegetation should be measured remotely to characterize it?


  • de Beurs, K.M., and G.M. Henebry: Phenological mixture models: Using MODIS to identify key phenological endmembers and their spatial distribution in the Northern Eurasian semi-arid grain belt.
  • Doubková, M., and G.M. Henebry: MODIS and AMSR-E vegetation indices for land surface phenology studies in the Eurasia semi-arid grain belt.
  • Kovalskyy, V., and G.M. Henebry: Change and persistence in land surface phenologies in the Don and Dnieper River Basins.

Although GIScCE scientists Drs. Shunguang (Leo) Liu and Tom Loveland are not able to attend the meeting, their research will be presented as a poster in the Friday special session entitled Regional to Continental-Scale Carbon Cycle Science: Progress in the North American Carbon Program, CarboEurope, and Related Programs:

  • Liu, S., Z. Li, T. Loveland, and L. Tieszen: Contemporary carbon trends in the eastern United States.

In addition Leo’s work will also be featured in a talk in the special session entitled Geomorphic Controls on Carbon Dynamics:

  • Sunduist, E.T., K.V. Ackerman, R.F. Stallard, N.B. Bliss, and S. Liu: Historical influence of soil and water management on sediment and carbon erosion and burial in the United States.
