| The six subspecies differ clinally, the birds becoming smaller and paler towards the east of the range. |
|
| There are several subspecies of the common starling, which vary clinally in size and the colour tone of the adult plumage. |
|
| In addition to variation at the colony level, P. phylax exhibited traits that varied clinally along the transect at the individual level. |
|
| Again, across the hybrid zone the frequency of these two bases varied clinally. |
|
| In contrast, desiccation tolerance varies clinally with latitude on all three continents, although not in parallel. |
|
| Most human biological variation is clinally distributed and blends gradually from one area to the next. |
