Social Influences on Reproduction in Pine Voles

Mechanisms of reproductive suppression in female pine voles (Microtus pinetorum).

In co-operatively breeding birds and mammals, philopatric females are often reproductively suppressed. Many studies have focused on the functional significance of reproductive suppression, but further investigation of the mechanisms involved is required for a complete understanding of this process. This study investigated whether reproductive suppression in non-reproductive female pine voles (M...

SOCIAL BEHAVIOR OF THE PINE VOLE (Pitymys pinetorum): I. ACTIVITY PATTERNS OF MATED PINE VOLES IN SEMI-NATURAL ENVIRONMENTS

Radiotelemetric Evaluation of the Effect of Horticultural Practices on Pine and Meadow Voles in Apple Orchards: Ii. Herbicide Application

Pine voles (Microtus pinetorum) and meadow voles (Microtus pennsylvanicus) were studied in a commercial apple orchard in the Hudson Valley of New York during April and May 1981. Selected voles were given miniature radiotransmitters and then tracked before and after herbicide application. A total of eight pine and meadow voles were tracked throughout the experimental period. H0m.e range size dec...

Ultrasonic calling in 2 species of voles, Microtus pinetorum and M. pennsylvanicus, with different social systems

When isolated, pups of muroid rodents emit ultrasonic vocalizations, an indication that they are stressed by being alone and exposed to cooling temperatures. Rate of vocalizations is greatest at the end of their 1st week and beginning of the 2nd week, declines in the 2nd week as eyes open and thermoregulation becomes fully established, and ceases in the 3rd week. Young of 1 vole species, the pr...

The Role of Sensory Cues and Feeding Context in the Mediation of Pine-Needle Oil's Repellency in Prairie Voles

Pine-needle oil inhibits feeding in vertebrate species through sensory cues. Prairie voles (Microtus ochrogaster) significantly decreased their ingestion of raw apple pieces when pineneedle oil (10% vol/vol) was applied as a repellent coating. During single-choice tests, voles selected similar amounts of sunflower seeds from pine-needle oil-scented jars and vegetable oiltreated jars. However, w...
