Also there are geographic gradients or clines, in number of folds.
The relative length of tail also provides gradients or clines.
Actually, however, none of the clines has an even slope and the possibilities for subdivision therefore are limited.
The application of the name streatori is difficult because it was based on a specimen from a place where two clines cross.
I couldn't believe it, because I know Colonel clines ain't going to block himself up in a cage.
They were placed in the Union depot to guard the ammunition, Captain clines at the head?
A gradual change in an inherited characteristic across the geographic range of a species, usually correlated with an environmental transition such as altitude, temperature, or moisture. For example, the body size in a species of warm-blooded animals tends to be larger in cooler climates (a latitudinal cline), while the flowering time of a plant may tend to be later at higher altitudes (an altitudinal cline). In species in which the gene flow between adjacent populations is high, the cline is typically smooth, whereas in populations with restricted gene flow the cline usually occurs as a series of relatively abrupt changes from one group to the next.
