0 a group of atoms that gives a chemical compound its characteristics, such as the ability to react with particular substances: --
In the knowledge model for the entire object, a functional group is considered as a component.
Parameters were calculated for each species, then averaged over all species in each functional group.
The association of activity rhythm with the other niche variables, food selection, functional group, body size and relative abundance, was analysed using multiple correspondence analysis.
This group can already be a spin label or a functional group which reacts selectively with a spin label possessing a complementary functional group.
This assumes that the key functional group in all human tissues (including brain) is histidine imidazole.
In the present study the functional group of trees from floodplains was analysed, and seed dry mass ranged over four orders of magnitude.
Distributions were calculated for each species, then averaged over all species in each functional group.
Red oak litter promotes a microarthropod functional group that accelerates its decomposition.
