A Morphometric Analysis of Geographic Variation Within Sorex Monticolus (Insectivora, Soricidae) (Classic Reprint) - Tapa blanda
Sinopsis
Excerpt from A Morphometric Analysis of Geographic Variation Within Sorex Monticolus (Insectivora, Soricidae)
Straight - line polygons were drawn around the published marginal records (hall, 1981; Hennings and Hoffmann, 1977) for each subspecies to form the 14 a priori' groups (fig. Specimens from localities within a polygon were considered to belong to the taxon for which marginal records were used to produce that polygon. Specimens from localities outside of polygons (n z 107) were not included in the initial analyses, but were as signed to their appropriate groups by use of diagno sis files created with two or three-group discrimi nant analyses between geographically adjacent a priori groups. Because Carraway 1990) consid ered S. Bairdi a distinct species, and my results corroborated this, S. Bairdi (n 110) was used as an outgroup.

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.

Paperback. Condición: New. Print on Demand. This book is a definitive study of the evolutionary history of a widespread and morphologically variable mammal, the dusky shrew. Using a quantitative approach with modern analytical techniques, the author assesses the validity of numerous subspecies and finds that many of them are dubious. The author's results have significant implications for understanding the evolution of the dusky shrew and the evolutionary processes that drive variation in mammals. Comprehensive and meticulously researched, this book will be of great interest to mammalogists, evolutionary biologists, and conservationists. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Nº de ref. del artículo: 9780243895687_0
