Title: Spatial patterns in the moose-forest-soil ecosystem on Isle Royale, Michigan, USA: Journal: Ecological Applications; Authors: J. B. Pastor, B. Dewey, R. Moen, J. Mladenoff, M. White, and J. Cohen; Date: 1998; Summary: Some of the highest moose (Alces alces) densities in the world are on the Isle Royale in Michigan and it is believed that moose browsing has caused a shift from hardwood to conifer dominated forest in this area. The authors tested three geostatistical models of the spatial distribution of available browse, annual browse consumption, conifer basal area, and soil nitrogen across the landscape: (1) random spatial distribution; (2) spherical model; and (3) harmonic oscillator model. The results of this study suggest that as moose use increases, the number of small aspen (< ...; Agrovoc Control Words: Riparian zones, Rangelands, Wildlife; View more details about this article
