“Even within a subspecies, vocalizations vary between sample points in a manner consistent with points along a cline.”

“Uncharacteristically for most squamates, the Eastern fence lizard exhibits a Bergmann size cline over its geographic range.”

“In contrast to the weak clinal pattern in wet weight, wing area showed strong negative slopes with T cline at all rearing temperatures.”

“Here, when there is cooperativity and the repressive activities of u and v are balanced the null clines, being sigmoids, intersect three times.”

“In fact several inversions have been found to form clines with higher frequencies at low latitudes near the equator.”

“There are numerous examples of population differentiation in body size and development time along latitudinal and elevational clines.”
