Above 250 nm, the variation declines further until none is observed above ∼290 nm.
Under the ELSE condition, this latitudinal difference of TEC's seasonal variation declines.
GEC has a significant seasonal variation dominated by the semiannual component during the normal solar cycle period; with solar EUV decreasing, GEC's seasonal variation declines so that it is relatively small under ELSE conditions.
In the case of both KMH and TSU observatories, Z-component secular variation declines between 2010 and 2013.5 at a rate of −3.2 and −3.6 nT/yearespectivelyvely, while from around 2013.5 the secular variation increases at a rate of 15.5 and 8.8 nT/yearespectivelyvely.
Such processes may also influence the evolutionary potential of populations and species, particularly if adaptive genetic variation declines to a point where populations can no longer adapt to changing environmental conditions (Young et al. 1993).
According to the Child Growth Standards published by the World Health Organization [ 23], the variation of body weight in infants is most marked and the extent of variation declines with age.
The peak-to-peak irradiance variation declined with increasing wavelength, reaching ∼10% just below the Al edge at 208 nm.
The key findings of this study were: (1) In P1 an initially large variation in intake was recorded with only some horses showing a neophobic response to a new odour/food, but variation declined within 2 days with the majority of the horses consuming over 90% of the diets.
Furthermore, this plasma biomarker has a seasonal variation, declining in winter and rising in summer, reflecting sunlight exposure (Holick, 2004).
Relative to the entire region sampled in this study, measures of genetic variation declined significantly when data were partitioned within island or mainland locations and particularly for individual populations, many of which were genetically homogeneous for AFLP markers.
