Plant traits - a tool for restoration?

摘要: Question Most results of restoration efforts are species-specific and/or site-specific and therefore not general enough to be easily applied other species sites. Our research addresses the issue by investigating feasibility using plant traits instead taxonomic identity characterize responses treatments. Location Ten bunchgrass prairie sites in Pacific Northwest North America (Oregon zashington, USA; British Columbia, Canada). Methods We developed two types quantitative models for each ten sites: (1) trait models, which related field following management treatments; (2) treatments. Species determined maximum amount variability that can explained differences individual species' Plant what proportion this explanatory power attributed traits. The model addressed specific questions: how much (changes cover) plants treatments is traits; well do explain compared relating identity? Results (1) within sites, with R2 values ranging between 31% 69%. 47% 74% change cover (R2). Thus, nearly as models. In seven out nine were superior measured AIC, i.e. did at explaining less complexity. Conclusion Strong supports a common language
