Further, the speciation effects of chemical defence and of conspicuous coloration are independent from each other, so when a toxic species then evolves conspicuous colouration, the increased diversification rate that accompanies colouration may offset the reduced diversification rate conferred by chemical defence.
It is therefore expected that variations among rates in different media result principally from U speciation effects, and not the bacterial processing rate for U VI).
These particular acids were chosen to systematically examine speciation effects on U precipitation rates, as a function of chelate ring size and aqueous U VI) complex stability.
At equilibrium, all thermodynamic functions of the anolyte redox reactions were the same after activity coefficients and speciation effects were taken into account.
From the OCP data, it was found that activity coefficient and speciation effects were critical in predicting the Gibbs energy, entropy and thermodynamic (intrinsic maximum) efficiency of the electrolytic cell.
Moreover, temporal effects such as the age of the tropical biomes, ages of clades (both time-for-speciation effects) and temporal changes in diversification rates can also modulate the rate of accumulation of species between the tropics and the non-tropics resulting in the observed diversity gradients.
From an ecological point of view, reproductive isolation is, however, not sufficient for achieving a speciation event of lasting effect.
X-ray absorption and infrared spectroscopy showed that the aqueous uranium speciation has no effect on the uranium binding process by this yeast strain.
However, founder effect speciation by reproductive isolation may evolve over several hundred generations.
Center-based research allowed a major effort to characterize size distributions, chemical speciation, and the effect of atmospheric processes of UFP to be integrated with toxicologic research (Donaldson and Stone 2003).
