Ecosystem models are important tools for diagnosing the carbon cycle and projecting its behavior across space and time. Despite the fact that ecosystems respond to drivers at multiple time scales, most assessments of model performance do not discriminate different time scales. Spectral methods,...

Salvage logging, edge effects and carabid beetles: connections to conservation and sustainable forest management
Download2006
Cobb, T.P., Brigham, R.M., Philips, I.D., Spence, J.R.
We used pitfall traps to study the effects of fire and salvage logging on distribution of carabid beetles over a forest disturbance gradient ranging from salvaged (naturally burned and subsequently harvested) to unsalvaged (naturally burned and left standing). Significantly more carabids were...

Structure and composition of riparian boreal forest: new methods for analyzing edge influence
Download2001
Abstract: Riparian ecotones at lakeshore edges are prominent features on the heterogeneous boreal forest landscape. We introduce a new method (the critical values approach): which incorporates inherent variability in interior forest, to quantify distance of edge influence at lakeshore forest...
