This paper describes the experimental investigations and presents the data that confirm reasonably robust autogenous healing of ECC in commonly encountered environments for many types of infrastructure.
This doctrine was useful in the Islamic world outside the Middle East where the Muslims encountered environments and challenges they had been unfamiliar with in Arabia.
Costs associated with maintaining such high levels of polyphenism are expected to trigger the evolution of reaction norms that facilitates adaptation to more frequently encountered environments [28].
The attenuation of the S. Typhimurium ΔsucAB and ΔsucCD mutants in mice, compared to their increased net intracellular replication in resting and activated macrophages suggest that Salmonella may encounter environments within the host where a complete TCA cycle is advantageous.
The contrast between the attenuation of the S. Typhimurium ΔsucAB and ΔsucCD mutants in mice, and their increased intracellular replication in resting and activated macrophages suggest that Salmonella may encounter environments within the host where a complete TCA cycle is advantageous.
For simplicity we assumed that the population encountered environments one at a time and survived all environments.
Rarely encountered environments may sometimes impose stronger selection than common environments, limiting population variation at environmental extremes.
Several studies have also shown that residents of neighborhoods with higher poverty rates encounter environments conducive to stressors and riskier behavior [ 28- 30].
RET in RA mechanoreceptors encounters environments in which both cis and trans activation are possible, providing a good model system to study the physiological functions of trans RET signaling.
Alternatively, functional redundancy for production of essential metabolites or gene products might facilitate maintenance of substantial population variation even for genes that are expressed in the most frequently encountered environments.
