Sentence examples for an evolutionary decrease in from inspiring English sources

These results are similar to a previous study, where predation by the protozoan Tetrahymena thermophila led to an evolutionary decrease in the pathogenicity of S. marcescens bacterium [40].

Alternatively, an evolutionary decrease in developmental rate would enable salmon to delay emergence despite the warm water below the dam.

Strong directional pressures on size due to selective harvesting have been shown to directly drive an evolutionary decrease in body size in bighorn sheep (Ovis canadensis).

Also any evolutionary decrease in growth rates might be hidden by the plastic increase due to reduced population density and competition for food.

We weighed the empty guts of fish from different lines and found that selecting on large brain size caused a correlated evolutionary decrease in gut size (β = −0.81 [−1.14; −0.49], p < 0.001).

Protozoan-driven evolutionary decrease in S. marcescens' virulence could be explained by decreased motility or resource use ability [15].

The process of tail shortening in rattlesnakes is likely a function of the relative contribution of caudal vertebral elements fused into the bony style (as opposed to evolutionary decrease in number of caudal segments); thus tail length is inversely related to rattle size.

Therefore, protozoan predation could lead to an evolutionary increase or decrease in bacterial virulence depending on which bacterial defensive traits are selected for, and how these traits are correlated with bacterial virulence factors.

This suggests that the 42% lower overall evolutionary rate of TM regions relative to EM regions (fig. 2) is due to a combination of two effects: 1) a general enrichment for buried, slowly evolving residues in TM regions (fig. 3 A) and 2) a systematic decrease in the evolutionary rates of all TM residues, independent of degree of burial (fig. 4).

We then analyzed the impact of coding fRNAs on the evolutionary rate of protein-coding genes because a decrease in evolutionary rate implies constraint due to biological functionality.

For this gene family there has been a significant decrease in evolutionary rate with time (P = 0.00069, Figure  6a), but it is mainly lead by the values sampled for the oldest node at the root of the family.
