It has been shown previously that a 5[degrees]C difference in water temperature can cause a selection pressure
strong enough to result in genetic differentiation (Dahlhoff & Somero 1993, Lin & Somero 1995).
This reflects increased bacterial selection pressure
as a result of widespread antibiotic use.
However, if the process seems immutable, does this imply that selection pressure
remains stable over time?
Unlike anthelmintic treatment, the resistant host does allow some worms to survive, so the selection pressure
on the worms is much lower,' Eady says.
For there to be significant inherent mental differences among racial groups, there would have to have been significantly different selection pressure
This preference Schiefenhovel takes as a proximate cause, behind which population control under selection pressure
stands as a final cause.
If such patterns conferred some survival advantage early in life they would have come under stronger selection pressure
than any detrimental effects they produced late in reproductive life |11~.
Similarly, Lotus Corporation, despite the turbulence of the computer software industry, is buffered from selection pressure
due to the phenomenal success of its initial product introduction.
Chapter 25 Environmental Microbial Communities Living Under Very High Antibiotic Selection Pressure
This analysis provides new evidence that regulators of innate immunity may exert selection pressure
on tumors and play an active role in the natural history of colorectal cancer.
None of those thrown in took the opportunity presented them to place any kind of selection pressure
on their manager.
None of the players thrown in took the opportunity presented to them to place any kind of selection pressure
