The beautiful patterns on butterfly wings are emerging as exceptional model systems that may reveal much about how the shapes, sizes and colors of specific organisms have evolved, a type of study ...

A large population of mixed species of Castilleja was sampled for morphological variability, with each of 100 collected plants being keyed to species, many on a "best fit" basis. Using taximetric ...

BUFFALO, N.Y. -- The beautiful patterns on butterfly wings are emerging as exceptional model systems that may reveal much about how the shapes, sizes and colors of specific organisms have evolved, a ...

Colorectal neoplasia has traditionally served as a paradigm of tumorigenesis in which the stepwise accumulation of genetic alterations was linked to the tumor’s morphological progression from adenoma ...

Abstract: We studied morphological relationships within three guilds of gerbillid rodents in Israel. We found a nonrandom pattern of overdispersed means (community‐wide character displacement) for ...
