The phrase "a constant selection pressure" is correct and usable in written English.
It can be used in discussions related to evolutionary biology, ecology, or any context where the concept of consistent environmental factors influencing a population is relevant.
Example: "In this environment, a constant selection pressure has led to the development of unique adaptations among the species."
Alternatives: "a continuous selection pressure" or "an ongoing selection pressure".
The rapid rise of resistance suggests that alleles conferring a better fitness in presence of insecticides are already present in susceptible populations and can be promptly selected under a constant selection pressure.
Excessive utilization of non-degradable antibiotics by human patients or in farm animals might lead to accumulation in the water compartment and subsequently to the promotion of resistance development when wide areas containing relevant bacteria have sufficient concentrations of active antibiotics leading to a constant selection pressure on the bacteria.
This population is allowed to evolve under a constant selection pressure for mediating two separate responses.
The basic idea was to neutrally evolve P450s under a constant selection pressure in populations that were either monomorphic or highly polymorphic, and observe whether the proteins evolved to different levels of mutational robustness and stability.
Such a rapid response by phages suggests bacterial host populations will be under a constant selection pressure to renew resistance, and emphasizes the power of the CRISPR/Cas system to confer such evolutionary flexibility.
ART imposes a constant selection pressure that favours highly drug resistant viruses that can grow under these conditions, and the loss of viral control due to superinfection by a resistant virus would likely result in repeated resistance testing, which would enable the detection of the event in our database.
With the assumptions of a homogeneous habitat (constant selection pressure), short-range migration, and negligible epistasis, our model is a first step toward understanding clonal interference in spatially structured populations, such as microbial colonies or biofilms.
In contrast, the local-score simulations display a constant average ω, which we think is more consistent with a neutral model, such as SCPE, with constant selection pressure λ.
Alternatively, neutral markers may have diversified over a long period of time, during which the metabolic phenotype was maintained by constant selection pressure.
The fact that this translocation, after constant selection pressure subjected in vivo, was the only chromosomal aberrancy inhabiting the tumor cells alludes to its advantageous tumorigenic properties to the cells.
The constant selection pressure by the spleen in vivo may alter the MCD profile of wild-type parasites.
