Variation In Pappogeomys Castanops (Geomyidae) On The Llano Estacado Of Texas And New Mexico, Robert C. Dowler, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

Nongeographic and geographic variation in the yellow-cheeked pocket gopher, Pappogeomys castanops, were analyzed in specimens collected in northwestern Texas and eastern New Mexico. Univariate and multivariate methods of analysis were utilized to assess variation in morphometric characters among 12 samples of P. castanops. Because of significant variation with age, only adult specimens were used in analyses. Adult males were significantly larger than females in all 13 characters studied. Our analyses of geographic variation reveal that those specimens previously assigned to the subspecies P. c. simulans are not sufficiently distinct to warrant subspecific designation.

Homeless Cats And Dogs Are Suffering And Dying

Close Up Reports

Last year more than 13 million homeless cats and dogs were euthanized at humane societies and municipal animal shelters. As a statistic, 13 million may be meaningless. But think of it another way. Think of the 13 million as individual animals with individual personalities--each with their own beating heart, each with their own wretched story of how they found their way to the animal shelter. Each one was an individual breathing creature whose life was ended because there was no home to go to.

Wolf Howling And Its Role In Territory Maintenance, Fred H. Harrington, L. David Mech

USGS Northern Prairie Wildlife Research Center

The wolf (Canis lupus) is a wide-ranging social carnivore with a complex spatial organization (MECH, 1972; 1973). The precise manner in which this organization is maintained is unknown, but territory advertisement using olfactory and acoustic modes seems to be involved.

The acoustic mode includes primarily howling. Within a wolf pack, howling may be useful to reassemble separated members (MECH, 1966; THEBERGE & FALLS, 1967), and may communicate information on individual identity, location, and other behavioral and environmental contingencies (THEBERGE & FALLS, 1967). Between packs, however, howling may serve to advertise territory, communicating the locations of packs and thus …
