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

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...

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...

Oxytocin receptor distribution reflects social organization in monogamous and polygamous voles.

The neuropeptide oxytocin has been implicated in the mediation of several forms of affiliative behavior including parental care, grooming, and sex behavior. Here we demonstrate that species from the genus Microtus (voles) selected for differences in social affiliation show contrasting patterns of oxytocin receptor expression in brain. By in vitro receptor autoradiography with an iodinated oxyto...

Effect of Photoperiod on Activity Patterns in Pine Voles (microtus Pinetorum)

Bait Stations for Controlling Voles in Apple Orchards

Bait stations made with polyvinylchloride (PVC) pipe were compared with hand-broadcast applications of rodenticides for achieving long-term control of pine and meadow vole populations (Microtus pinetorum and M. pennsylvanicus, respectively) in two apple orchards in the mid-Hudson Valley of New York. The stations were constructed of three pieces of 1.5-in diameter PVC tubing joined together in t...
