There is even evidence for personality trait differences among people in different specialties, and these differences in personality could influence practice styles [ 10, 11].
Grasses and forbs differed in almost all above- and belowground traits, while trait differences related to growth stature were generally small.
trait differences are inherited between generations, 3.
These trait differences must in-turn cause species variation in demographic performance across habitats.
Competition and coevolution provides a plausible explanation for trait differences between coexisting species, but unfortunately it is not the only explanation.
Species-specific trait differences and unique ecological strategies affect population dynamics and the functioning of entire ecological communities (Wiegand et al. 2007).
It starts with the assumption that trait differences are caused by the factors with which they correlate, an assumption I will not question here.
This recalls the way in which classical geneticists related gene differences and trait differences in the differential gene concept, where trait differences were used as markers for genetic differences without implying a deducibility of trait behavior, the dominance or recessivity of traits in particular, from Mendelian laws (Schwartz 2000; Falk 2001).
With the great progresses in the methods of detecting trait differences and genetic variations, GWAS has emerged as a promising approach to inspect the relationships between complex genetic polymorphisms and distinctive phenotypes for most species (Slate et al. 2009).
traits of organisms vary among individuals within populations, trait differences are inherited between generations, traits provide an advantage in the struggle for existence under competition for resources and in different environmental conditions.
Since the multiple genes of roots are found to have spatial and temporal differences in their expression and function, the search for the trait differences, genes and their function need to be expanded with large set of mutant resources (Wei et al. [2013] for a review).
