The initial probabilistic function for any gene i in functional group h became (12) f h (x i ; Θ h ) = ∑ c = 1 C π h f c (x i ; θ c ) where Θ h = { π h, θ c}.
Interestingly, the chemical scaffold of DB00631 shares the same purine subunit as abacavir, but has key differences in functional group placement at the two and six position.
We classified the South African avifauna into nine functional groups and tested at a coarse grain for differences in functional group composition between landscapes containing predominantly agricultural vs. protected areas.
The plots also encompassed a gradient in functional group richness (1, 2, 3, and 4) in a factorial design.
While stress did not affect the relation between functional group richness and stability per se, the way in which functional groups responded to changes in functional group richness differed as stress increased.
Temporal variability in functional group abundance declined significantly with increasing functional group richness (FGR) for all functional groups except for cyclopoid copepods and ostracods, both of whom showed negative, albeit insignificant, trends (Table 3).
