Karyotypes of the Mexican tropical voles Microtus quasiater and M. umbrosus (Arvicolinae: Muridae )

Morphological characterisation of Paranoplocephala bairdi (Schad, 1954) (Cestoda: Anoplocephalidae) in heather voles Phenacomys spp. and tree voles Arborimus spp., and related species in voles and lemmings (Muridae: Arvicolinae).

The taxonomical status of Paranoplocephala bairdi (Schad, 1954)-like cestodes (Anoplocephalidae) in heather voles Phenacomys spp. and tree voles Arborimus spp. (Muridae: Arvicolinae) and their discrimination from five related species of Paranoplocephala is assessed using uni- and multivariate morphometrics. The analyses support the independent status and conspecificity of specimens from Phenaco...

Karyotypes of four rats (Rodentia: Muridae) from Sulawesi (Celebes), Indonesia.

Karyotypes and information pertinent to genetic mapping of small mammals in remote areas of Southeast Asia are practically nonexistent. The diverse island complex of the Indo-Australian archipelago offers a unique situation to study the interrelationships of the taxonomically confused order Rodentia. Yosida (1969, 1971, 1973) reported karyotypes of two species of rodents from Makassar, located ...

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...

Self discrimination in meadow voles, Microtus pennsylvanicus.

Particular features of the signaling characteristics of the scent marks of temperate-zone, seasonally breeding mammals may reflect differences in their reproductive state and, hence, be variable. Consequently, an individual's perception of self may depend more on the condition independent than on the condition-dependent signaling characteristics of the scent marks. Yet, we do not know whether a...

STATUS OF WINTER POPULATIONS OF PINE VOLES (Microtus pinetorum
