Besides being an important process for the protection of receiving waters, nitrification served as a proxy for the understanding of the behavior of a narrowly defined group of microorganisms growing on known substrates under environmental conditions.
Cumulatively, our data suggest that apoptosis, being an important process during post-eclosion wing maturation, is unlikely to be the sole driving force behind wing expansion.
Accordingly, among the recent proviral copies (i.e., those ≥99% identical to the consensus), deletions are more frequent than insertions (63% versus 37%), being an important process for the inactivation of the proviral copies in the preliminary stages of their evolution in the genome, together with solo-LTR formation [10], [11].
These results also suggest that cold-acclimation may stabilize the electron transport chain polypeptides within the thylakoid membrane or maintain their turnover, being an important process for conferring a faster recovery from photoinhibition in the hardiest ecotype.
The reproductive isolation criterion recognizes that reduced gene exchange plays a pivotal role characterizing species boundaries [ 10, 11] and is widely accepted among evolutionary biologists as being an important process leading to the divergence of sexually reproducing species [ 12].
