Graph-Theoretic Modeling of Functional Habitat Connectivity for Lynx on the Okanogan Highlands, Northern Washington: Author: Jones, Aaron Paul; Date: 2004-12-15; Program: Earth Sciences; Abstract: Maintenance of habitat connectivity over various geographic scales is a conservation imperative for the long-term persistence of many species. Functional linkages for a given focal species may not be readily apparent or spatially coincident with explicit structural patterns in a landscape. In species-level habitat connectivity modeling, therefore, techniques derived from empirical data are needed to sustain a species-centric perspective on landscape mosaics. This study demonstrates an empirically-based, combined Bayesian and graph-theoretic approach to modeling functional habitat connectivity....; Download File | View full details

The Influence of Riparian-Canopy Structure and Coverage on the Breeding Distribution of the Southwestern Willow Flycatcher: Author: Brodhead, Katherine May; Date: 2005-08-15; Program: Earth Sciences; Abstract: There is a long history of relating bird species diversity and distributions to heterogeneity in foliage structure as seen from within the habitat and measured from the ground up. There is also an overwhelming contribution in the literature promoting and justifying a broad-scale approach to characterizing spatial patterns, especially for the purpose of relating to, and predicting, species distributions. This study draws from the relationship between birds and habitat structure but assesses heterogeneity in structure from a broader perspective. For this analysis, I compared the spatial distribu...; Download File | View full details
