Species differences in anxiety-related responses in male prairie and meadow voles: The effects of social isolation Jennifer R. Stowe a, Yan Liu a, J. Thomas Curtis a, Marc E. Freeman b, Zuoxin Wang a,* a Department of Psychology and Program in Neuroscience, Florida State University, Tallahassee, FL , USA b Department of Biological Sciences and Program in Neuroscience, Florida State. Species Differences in Anxiety-Like Behaviors. Prairie voles exhibited less anxiety-like behavior in the OFT and LDB (Figures 1D,E).In the OFT, prairie voles spent significantly more time in the exposed center than did meadow voles (t (35) = , p.
In a population of starlings where some males helped their mates incubate their eggs and others did not, the clutches with biparental care stayed warmer. 97% of the eggs with biparental care hatched, vs. 75% for eggs with female uniparental care. Clutches with high parental care are staying much warmer. One female cannot keep the egg warm enough. Female meadow voles, which do not form OT-dependent partner preferences, were injected with MTII (10 mg/kg) or saline (n=9–11/group) as described above to assess potential non-OT-dependent.
MEADOW voles (Microtus pennsylvanicus) are small ( g) arvicoline rodents believed to be induced into behavioral estrus through contact with a mature male or his urine (29), and copu- latory behavior subsequently induces ovulation (6,20). Meadow voles are seasonal breeders, with most females producing young. Meadow Voles. Color: They have long and coarse fur that is usually blackish brown to grayish brown. Characteristics: Meadow voles, also sometimes called meadow mice or just plain “voles”, are small mammals, They have a compact and fat little body with short legs and a short furry tail, small eyes and partially hidden ears. Size: Meadow voles are usually between 5 inches and 8 inches long.

Meadow voles are an important prey for many hawks, owls, and mammalian carnivores, and they are also taken by some snakes. Almost all species of raptors take microtine (Microtus spp.) rodents as : Cricetidae. Nature Notes: Meadow Vole.

Every spring when the snow on our lawn finally melts, we find a series of tunnels in the dormant grass, along. Such variations in behavioral and physical development of litters among microtine rodents are consistent with the patterns of life-history strategies originally described by MacArthur and Wilson ().
Promiscuous species such as meadow voles usually live in unstable habitats, show extreme population fluctuations, and breed by: Predators: The usual predators of small mammals eat meadow voles.
Some of these are weasels, foxes, hawks, owls, the coyote, bobcat, and short-tailed shrew. Social Behavior: Social system - During the breeding season, reproductively active females maintain territories from which they exclude other females. Males occupy home ranges of Dynamics of social nesting in overwintering meadow voles (Microtus pennsylvanicus): possible consequences for population cycling.

– Oikos – When voles aren’t numerous or when the population is concentrated in a small area, trapping can be effective.
Use a sufficient number of traps to control the population. For a small garden a dozen traps is probably the minimum number required, but for larger areas, you might need 50 or more. The increase in paternal behavior in cohabitating meadow voles is mediated by AVP, as treatment with AVP antagonist decreases paternal behavior [14, ].
Elevated AVP in meadow voles stimulates paternal behavior through both a decrease in pup directed aggression and an. Overwintered voles had the majority of the reproductive success along with a striking increase in the population size in the enclosures, with all biological fathers and % of biological mothers.
Future work using advanced sequencing techniques, such as ATAC-seq and 4C-seq performed on pallidal tissue in prairie and meadow voles is needed to delineate the contributions of distal regulatory elements. 84,85 In addition, advanced genome and epigenome editing techniques provide a powerful approach for functionally interrogating candidate regulatory differences.
Ultimately, a. Patterns of population dynamics are determined by the interaction between density—dependent and density—independent processes. To examine the responsiveness of various demographic and behavioral processes to population density, we maintained replicate meadow vole (Microtus pennsylvanicus) population at low, medium, and high densities inside field exclosures in southern.
Adult meadow voles (Microtus pennsylvanicus) are solitary in the spring–summer reproductive season, but during winter months, females and males are socially tolerant and aggregate in behavioral difference is triggered by day length: female meadow voles housed in short, winter-like day lengths form same-sex partner preferences, whereas those housed in long, summer-like day lengths.
Meadow voles make extensive runways through vegetation which provide concealment from predators when traveling at all times during the day and night.
Description This species is usually dark brown in color with a silvery to slightly buff or dark gray belly and bi-colored tail. Meadow vole, (Microtus pennsylvanicus), one of the most common and prolific small mammals in North America. Weighing less than 50 grams ( ounces), this stout vole is 15 to 20 cm ( to inches) long, including its short tail (3 to 6 cm).
The dense, soft fur is chestnut-brown above and gray. Free-ranging, sexually mature meadow voles (Microtus pennsylvanicus) were tracked by using radiotelemetry from June through August in Front Royal, Virginia, U.S.A.
Estimates of intraspecific spacing were derived from the concurrent movements of up to 16 voles. Positions were recorded hourly for 24 h, twice per week. A total of 16 male and 15 female voles were studied during sixteen h. However, Kansas voles are more socially and genetically monogamous than voles in an Indiana population and some of these population differences are associated with differences in estrogen receptor expression in the brain.
How do prairie voles and meadow voles differ in terms of their mating and reproductive behaviors (i.e. mating, strategy, parental care) --PRAIRIE VOLES: mate for life, or just breeding season, male stays around until after the pups are born and participates in parental care.
Female meadow voles housed in SDs in same-sex trios of littermates exhibited selective partner preferences for cage-mates over strangers when one of the cage-mates was randomly selected as the partner in behavioral tests (p.

Woodland Voles tend to be more reddish brown than Meadow Voles. Woodland Vole tails are shorter at 1/2 to 1 inch long, and these voles weigh 1/2 to 1 1/2 oz. Meadow Voles range through the northern third or so of the US and up through Canada.
Woodland Voles range through the eastern section of the US except for Florida and Maine. Home Rodent Control. Color: They have long and coarse fur that is usually blackish brown to grayish brown.
Characteristics: Meadow voles, also sometimes called meadow mice or just plain “voles”, are small mammals, They have a compact and fat little body with short legs and a short furry tail, small eyes and partially hidden ears.
Size: Meadow voles are usually between 5 inches and 8.The Meadow Vole, under 6 inches in length from tip of nose to end of tail and a little over an ounce in weight, has the rotund body, blunt nose, and bright black eyes of all voles.
On top it can be yellowish or reddish brown to dark brown, with black-tipped hairs. Below it .Behavior. The behavior of meadow voles is dependent upon the season. Throughout the more active breeding season (March-November) females are highly aggressive and territorial.
Females are aggressive towards both other females and males, when mating and caring for their pups.
