An idealized model was developed to describe leaf CO(2) exchange in the leguminous tree Erythrina poeppigiana (Walpers) O.F. Cook under well-watered field conditions. Photosynthetic rate in mature leaves (p) was modeled as a rectangular hyperbolic function of photon flux density (q) and ambient CO(2) concentration (c(a)), relative photosynthetic capacity (pi) was modeled as a logistic s-functio...

Wildfires, tree removals, and deer herbivory are potential pathways for spread of non-native plants. I modeled the number recorded nonnative plant species by county compared to wildfire area, densities in eastern United States also forests. Species richness 1016 780 primarily forested counties decreased with increased values three variables; models equally showed negative relationships. For mod...

Character strengths have been found to be substantially related to children's and adolescents' well-being. Initial evidence suggests that they also matter for school success (e.g., Weber and Ruch, 2012). The present set of two studies aimed at replicating and extending these findings in two different age groups, primary school students (N = 179; mean age = 11.6 years) and secondary school stude...
