Book Description

Excerpt from A Morphometric Analysis of Geographic Variation Within Sorex Monticolus (Insectivora, Soricidae) An ocular micrometer mounted in a Bausch and Lomb binocular microscope was used to measure 17 cranial and mandibular characters (fig. A Fowler max-cal electronic caliper with digital readout to mm was used to measure cranial depth and greatest length of skull. These 19 charac ters were selected because they are conventional dimensions found useful in previous studies of soricids (carraway, 1990; Choate, 1972; Diersing, 1980; van Zyll de Jong, 1980) and because they have objective endpoints and are consistently re peatable. Values for characters measured with the ocular micrometer were retained as number of ocular lines for analysis; values subsequently were converted to millimeters and are reported as such herein. Gender in Sorex does not seem to affect cranial morphology (rudd, 1955; van Zyll de J ong, in addition, many museum speci mens of Shrews are misclassified to sex (l. Carraway, pers. Comm.) thus biasing results claim ing a difference. For these reasons sexes were combined in this analysis.
