The phrase "a high selection pressure" is correct and usable in written English.
It can be used in discussions related to evolutionary biology, ecology, or genetics to describe a strong influence on the survival and reproduction of organisms.
Example: "In environments with a high selection pressure, only the most adaptable species are likely to thrive."
Alternatives: "strong selection pressure" or "intense selection pressure".
In all cases, a high selection pressure (but not an extreme one) combined with a moderately high mutation rate works best, while crossover provides some benefit but only on the less rugged landscapes.
This crucial role could have imposed a high selection pressure on the Pax6 gene making it indispensable.
In rye, a high selection pressure is on large, plump kernels, because rye as a crop tends to low kernel size limiting flour yield.
A high selection pressure was observed in our study population, represented by preoperative antibiotic therapy in 21% of cases, and systematic antibiotic prophylaxis.
The study of endogamy in cattle is extremely important, particularly due to the widespread use of artificial insemination, which allows a high selection pressure and rapid genetic gain, resulting in thousands of descendants from one single sire.
There is a high selection pressure for litter size at birth during the first and second litters in domestic sows compared with other traits in the breeding goal (e.g., the 2009 breeding goal for Norwegian Landrace sows).
Therefore putative CREs in CDRs are not necessarily under a higher selection pressure than are the randomly selected short k-mers in CDRs.
Hostile climatic conditions reduce the number of L3s on pasture and therefore the refugium, which is expected to result in a higher selection pressure, accelerating development of resistance against anthelmintic drugs.
High biliary excretion of ceftriaxone and its long acting properties are responsible for a higher selection pressure in comparison with cefotaxime, an antibiotic drug with the same microbial spectre, lower biliary excretion, shorter action and a negligible effect on the bowel microflora.
On the other hand, genic microsatellites are under a higher selection pressure [ 3], so they may not provide sufficient polymorphism to discriminate between closely related germplasm.
This study demonstrates the feasibility of using a BSA sequencing approach to rapidly identify QTL for two traits important for the production of lignocellulosic ethanol in maize while also yielding a context for selection on genomic regions using a higher selection pressure concurrently with a large population size.
