During the Pliocene the global climate fluctuated markedly with the expansion and contraction of the Northern and Southern Hemisphere ice sheets.
A "boom-and-bust" species, Gambel's Quail reproductive rates fluctuate markedly from year to year depending on the amount of green feed available in the spring.
He found that the level fluctuated markedly with the seasons, falling in northern summer as plants took up carbon dioxide and rising in northern winter as dead foliage rotted.
The number of fatal incidents as a percentage of all events fluctuates markedly between 6% and 14%, with no systematic trend.
While the right adrenal gland was being operated, APCO fluctuated markedly in more or less inverse proportion to the change in ABP, whereas PACO shifted rather smoothly (Fig. 3).
Temporal variability in edge phenomena was also only partially predictable: forest dynamics varied somewhat with fragment age, but also fluctuated markedly over time, evidently because of sporadic droughts and windstorms.
Fig. 4 shows the variation of the photosynthetic parameters, including the effective PS II quantum yield [Y (II)] and the optimum PS II quantum yield [Fv/Fm], which fluctuated markedly during sporangia formation.
This raised the question as to what extent salinity can impact on Tat-dependent protein secretion by microorganisms, like the soil bacterium B. subtilis, that live in ecological niches where the salinity can fluctuate markedly.
The ratio of sense/anti-sense transcripts in mouse cells fluctuates markedly among different tissues consistent with the hypothesis that anti-sense transcription serves as a gene regulatory mechanism during development.
