Session for 9th IALE World Congress July 5-10, 2015 Portland, Oregon
S15. Landscape Connectivity and Its Implications for Conservation Management and Planning
Organizers:
Mirela G. Tulbure
Carol A. Johnston

Overview:
Aquatic systems and their biota are some of the most threatened in the world. They are affected by changes in climate and land use, which not only increase direct pressure on surface water, but also affect dispersal opportunities for water dependent organisms, as water bodies dry out. Adaptations at regional scales require measures that allow species dispersal such as preserving or enhancing landscape connectivity for species movement. Graph theory is a powerful approach for assessing connectivity across scales. We invite submissions that integrate graph theory to assess connectivity across landscapes. We particularly encourage submissions with applications in aquatic systems.
