Seminar 2, April 10:  Spatial and Physical Models of River Networks and Processes across the Landscape

The session goals are to 1) consider alternative modeling strategies, detailed process versus aggregate models, and spatially-explicit approaches to salmon habitat modeling, 2) identify key spatial or physical features of salmon habitat as landscape-scale patterns that are/are not adequately addressed in existing approaches; which need to be included in overall scheme(s), and which can be willfully neglected, and 3) produce required in-stream flow from hydrologic models.

Lead Speakers:

Thomas Quinn (UW)

Tom Quinn's (tquinn@u.washington.edu) general interest is in fish behavior and ecology, particularly migratory behavior, techniques including tagging, telemetry and direct observations, with appropriate laboratory experiments. Much of his research is focused on salmon and trout. Dr. Quinn studies the patterns of spawning site selection and reproductive behavior of salmon, the effects of habitat alteration from logging on salmon and trout populations, the evolutionary adaptations of salmon to their environments, and the patterns of olfactory imprinting and homing by salmon.

Miles Logsdon (UW), University of Washington

Dr. Miles Logsdon (mlog@u.washington.edu) is a Research Assistant Professor in the School of Oceanography at the University of Washington. His research and teaching interests are focused on the use of GIS and Remote Sensing in the spatial analysis of physical earth system processes. He is primarily involved in interdisciplinary and collaborative research activities that focus on an integrated approach to the use of earth system data and spatially explicit process models.

Dr. Logsdon is the director of the Spatial Analysis Laboratory for the College of Ocean and Fishery Sciences and the University of Washington. He serves as the lead investigator on the development of the "physical template" for Puget Sound, an element of the Puget Sound Regional Synthesis Modeling project (PRISM) at the University of Washington, and is the director of the university-funded program for the "Coordinated Curriculum in GIS, Remote Sensing and Spatial Analysis for Earth Sciences and Natural Resource Planning." Other current research activities include a NASA application grant for the "Strategic and Practical Use of Remote Sensing in Emergency Management (SPURS-EM)." In addition Dr. Logsdon currently teaches two courses in the application of spatial information technologies and spatial data analysis. These courses are cross-listed and joint credit is awarded between four academic units.

Student Questions:

For Tom:
--What are the key stages of the different life histories by stock/species that we should be sure to capture in a habitat-fish modeling exercise?


For Miles & Pascal:
--What are the central aspects of the landscape (upland, stream channel) and flow regime that are most central to salmon?

--How can these central landscape features be described and linked to a fish-habitat model?

For all speakers:
--How does (insert speaker's area of expertise--e.g., life history diversity, hydrography, patterns of climate change) affect salmon in one or more life stages, and how do you recommend that those effects be translated into predictions about population capacity, growth or productivity?

--What are the 2 (or 3 or 4) biggest sources of uncertainty in making predictions about how (insert speaker's area of expertise here) affects salmon in one or more life stages?

--What 2 (or 3 or 4) alternative scenarios of current or future conditions would you suggest should be explored to make our model predictions about the effects of habitat change on salmon more robust to uncertainties?
