Trait choice profoundly affected the ecological conclusions drawn from functional diversity measures

Abstract Although trait choice is crucial to quantify functional diversity appropriately, the quantitative methods for it are rarely compared and discussed. Meanwhile, very little is known about how trait choice affects ecological conclusions drawn from functional diversity measures. We presented th...
