The aim of our IWM strategies is to reduce weed pressure and keep weeds within acceptable levels which make it easier for herbicides to function properly and reduce the selection pressure
for resistance, said Christine Brunel-Ligneau, Head of Bayer s IWM program.
Moreover, this may bias the apparent selection pressure
on parents, given that infanticidal events are inclined to occur at the nest of parents with a particular phenotype (e.
Use multiple effective herbicide Modes of Action (MOA) -- Use tankmix partners and multiple MOAs during both the growing season and from year to year to reduce the selection pressure
of a single MOA.
The former Harlequins stand-off makes the temporary switch from Newcastle Falcons to ease the selection pressure
on the Pro12 champions.
2013) was used for determining the best evolutionary model, for phylogenetic tree construction, estimation of evolutionary divergence, determining the amino acid composition and estimation of selection pressure
on coding sequences.
Another front row under selection pressure
, the veteran justified his inclusion
With his Falcons side unbeaten in their three European Rugby Challenge Cup games to date and homing in on a quarter-final place, the 24-year-old believes there are wider benefits with a host of fringe players applying serious selection pressure
ahead of the return to Premiership rugby.
Reliance on one method of weed control imposes selection pressure
, which can lead to population shifts to tolerant species or selection of resistant biotypes.
That suggests that genes encoding those proteins come under intense selection pressure
by the immune system during initial acute infection.
These management practices placed only light selection pressure
on the herd's gene pool.
The combination of these factors creates a strong selection pressure
on the organisms found there.
The evolutionary selection pressure
for male characteristics ranging from peacocks' plumage to deer's antlers to fighter pilots' heroism is pretty obvious: females, especially at mating-cycle peaks, prefer males with prodigious testosterone-driven traits.
