Reproduction: As some of the most prolific breeders in the rodent family, voles can produce 5-10 litters per year with 3-6 young per litter. similar to those recorded in industrial districts (Cu I-150mg/kg, Cu II-600mg/kg, C-control) affects the sexual behavior of small rodents. Vole Behavior. For this study on bank vole behavior, I collaborated with researchers from the Netherlands and Finland. We analyzed the hippocampus and liver transcriptomes and found repeatable changes … Bank vole I found while a tractor was moving dirt around. BIOLOGY AND BEHAVIOR. Bank voles are active during both the day and night, and forage over distances up to 50 metres. The behavior and vocalizations of male-female After 13 generations of selection, the proportion of bank voles (Myodes [=Clethrionomys] glareolus) showing predatory behavior was five times higher in selected lines than in controls. Poor guy was shaking in fear. The bank vole have claws so they can climb away from the predators and the fur are adapted to the colour of the woods and the sharp ears so they can be alert with the ear and the eyes. Voles reproduce throughout the entire year, with peak rates in the spring and summer. Male and female bank voles reared in different conditions were investigated for their aggressiveness in order to show how social factors modify intermale and interfemale behavior. Adult Bank Voles have a rich chestnut-brown back compared to the grey-brown fur of the Field Vole. The model species was the bank vole (Myodes glareolus). At first sight, they can be confused with field voles, which are greyer, or wood mice, which have a longer tail and bound rather than scurry. Voles are active day and night, year-round.

Bank voles are ever wary of danger, so most sightings are just a fleeting glimpse. They also have a much longer tail than the Field Vole. In areas with winter snow, voles will burrow in and through the snow to the surface. Populations of bank voles (Clethrionomys glareolus) were monitored during a 4-year study in southern Belgium to assess the influence of agonistic behavior, reproductive status, mobility, and distribution of the rodents on the dynamics of Puumala virus (abbreviation: PUUV; genus: Hantavirus) infection.Concordance was high between data from serologic testing and results of viral RNA detection. If you hear a rustling in the undergrowth, stay very still and quiet and you might catch a glimpse of a foraging vole. They have small eyes, small ears and a blunt snout.
