Modeling landscape dynamics and environmental association for spruce mortality
MetadataShow full item record
This study addresses important issues related to mortality of spruce species (Picea sp.) associate with outbreaks of spruce beetle (Dendroctonus rufipennis Kirby) by 1) modeling large scale landscape dynamics of spruce mortality associated with long-term climate in Colorado and Alaska; 2) modeling environmental association between spruce mortality and small scale environmental covariates including climatic factors. In the first chapter, we review the ecology and etiology of spruce mortality in Colorado. In the second chapter, we evaluate landscape dynamics of spruce mortality at the regional ...
