Questions:
(1) What combinations of overlapping water and heat stress and herbivory disturbance gradients are associated with shifts in interactions between Artemisia tridentata subsp. wyomingensis (Artemisia) and herbaceous beneficiary species? (2) Do interactions between Artemisia and beneficiaries shift from competition to facilitation with increasing stress-disturbance where facilitation and competition are...

study entitled Evaluating Cumulative Ecosystem Response to Restoration Projects in the
Columbia River Estuary (Diefenderfer et al. 2005). The major objective of the study was
to develop a...

Exotic species dominate many communities; however the functional significance of species’ biogeographic origin remains highly contentious. This debate is fuelled in part by the lack of globally replicated, systematic data assessing the relationship between species provenance, function and response to perturbations. We examined the abundance of native and exotic plant...

Forests are major components of the global carbon cycle, providing
substantial feedback to atmospheric greenhouse gas concentrations¹.
Our ability to understand and predict changes in the forest carbon
cycle—particularly net primary productivity and carbon storage—increasingly relies on models that represent biological processes
across several scales of biological organization, from tree...

We describe the use of linked land-use and forest sector models to simulate the effects of carbon offset sales on private forest owners' land-use and forest management decisions in western Oregon (USA). Our work focuses on forest management decisions rather than afforestation, allows full forest sector price adjustment to land-use...
