| It was assumed that factors that are under photoperiodic control would show a clinal order among the ecotypes. |
|
| Species rank is also indicated by the lack of indications of clinal variation or intergradation, despite direct evidence of dispersal. |
|
| Geographical variation results in clinal variation triggering aestival dormancy. |
|
| There was no significant allele frequency variation and the mean frequencies are not clinal. |
|
| Scatterplots show that those variables are related differently in the three putative species and appear not to vary in a clinal fashion. |
|
| In contrast to the weak clinal pattern in wet weight, wing area showed strong negative slopes with T cline at all rearing temperatures. |
|
| Clinal patterns were determined by linear regression of the trait means on clinal temperature. |
|
| Definitions for subspecies, clinal variant and other similarly distinctions below the species level are very open ended. |
|
| The null clinal pattern would be supported by a negative relationship between T cline, and wing loading, as we have observed for T cline, and size. |
|
| Thus there is no evidence for clinal variation that might bridge morphometric differences between the two species and lead us to synonymize them. |
|
| However, the species is now considered monotypic and the size variation is clinal according to Bergmann's rule. |
|
| A world-wide, north-south pattern of clinal photoperiodic adaptation correlated with stature has evolved in Cannabis. |
|
| In the last decades of the 20th century, scientists began to understand human physical variability in clinal terms and to recognize that it reflects much more complex gradations and combinations than they had anticipated. |
|
| This pattern of variation, known as clinal variation, is also observed for many alleles that vary from one human group to another. |
|
| Individuals of any race are somewhat variable and the differences between subspecies are clinal, especially in terms of body size. |
|
| Despite this clinal and intrapopulation variation in color, there is no record of an ocelot possessing white coloration anywhere except the belly. |
|
| The clinal geographic genetic variation is further complicated by the migration and mixing between human populations which has been occurring since prehistoric times. |
|
| Clinal variation in the size of the secondary sexual character may be due to the effects of the Fisher or the handicap process. |
