The phrase "adaptive selective pressure" is correct and usable in written English.
It can be used in discussions related to evolution, ecology, or biology, particularly when describing factors that influence the survival and reproduction of organisms.
Example: "In changing environments, adaptive selective pressure can lead to rapid evolutionary changes in species."
Alternatives: "evolutionary pressure" or "selective environmental factors".
That is, in environments where "cad" behavior is adaptive, selective pressure for 7R+ would be positive; but in environments where "dad" behavior is adaptive, selective pressure for 7R+ would be negative.
Our study challenges the 're-evolution' of osteological features by showing that 're-evolving' a 'lost' feature de novo (contrary to Dollo's Law) may instead be due to so called 'missing structures' being present but underdeveloped and/or fused to other adjacent elements (cryptic features) whose independence may be re-established under changes in adaptive selective pressure.
To assess what adaptive selective pressures might drive and maintain such massive gene expansions in A. digitifera, the expressed venom proteome was determined empirically using high throughput mass spectrometric protein analysis.
Whether the functional divergences are primarily due to adaptive selection pressure or relaxed selective constraint remains an open question.
The clear separation of Dent and Flint reflects their genetic differentiation for more than 2,500 years [ 41], accompanied by varying adaptive and selective pressures.
Higher rates of gene duplication and loss may reflect an adaptive response to selective pressure from pathogens, interactions with other organisms, or other environmental pressures.
Cells as the units of evolutionary selection then, but does this mean any or all cancer cells expressing relevant phenotypic traits that are adaptive to negative selective pressure?
Another mechanism that results in multiple hits and saturation is adaptive convergence, when selective pressure on morphological function results in homoplasious character states.
In some instances, the match of mutation, adaptive trait and selective pressure are transparent, as for example with resistance to specific drugs (Shah et al. 2002; Balak et al. 2006) or with immune-editing and immune pressure (Dunn et al. 2002; Vago et al. 2009).
Up-regulation of glycolysis has been demonstrated in multiple tumor types and is believed to originate as an adaptive response to the selective pressure of the tumor microenvironment.
Indeed, alternative mRNA splicing could offer a fast adaptive response to strong selective pressure encountered by natural populations in the field, such as pesticides.
