Yanev (1978) described parallel clines in the modal number of trunk vertebrae for three lineages in the central coastal ranges of California.
Modal number of trunk vertebrae was determined for 38 populations of Batrachoseps by x-raying, clearing and staining, or counting costal grooves.
Modal number of vertebrae in Batrachoseps populations ranged from 17 (B.
A minimum of 11 (female) and nine (male) increases in modal number of trunk vertebrae were inferred to have occurred, including increases in the ancestor of all Batrachoseps, the ancestor of the attenuate clade, B.
The degree of plasticity was great enough to cause a shift in modal number of trunk vertebrae in only two populations of B.
However, the change was sufficient to nearly cause a shift in modal number between 13 [degrees] C and 17.
Some of ``Skaravan'' (Hannibal/Ryko) is a bit reminiscent of the Dirty Dozen Brass Band, a mirth-filled outfit that takes be-bop and even modal numbers
and renders them New Orleans-style.
