    An important issue in plant ecology is the extent to which functional traits that explain patterns at one organizational level serve as explanatory variables at higher levels, while a related subject is the universality of relationships between traits and responses to environmental variables even at a given level. We addressed both questions experimentally by either mowing or abandoning plots within two meadows, one wet and one dry, and then measuring the performance of 42 species in terms of shoot growth and flowering (individual level) and species cover (population level), and relating these performance measures to traits. Our study found that only one trait had predictive value for responses at both the individual and population level for the environmental alteration consisting of mowing vs. abandonment The limited ability of the predictive power of traits to transcend organizational level and ecological milieu suggests that trait function is highly context dependent.
