Abstract

In microtine rodents, formation of communal groups often is associated with environmental stresses of winter or high population density. Social organization of the prairie vole (Microtus ochrogaster) consisted of communal groups formed by addition of philopatric young and unrelated adults to an original male-female pair or single-female breeding unit. Owing to high juvenile mortality during spring-early autumn, most social groups remained as male-female pairs or single females. Male-female pairs displayed behavioral traits associated with monogamy, including sharing a common nest and home range, mate guarding, dissolution of pairs by mortality, and low incidence of remating. Male-female pairs rarely involved related animals. Single-female breeding units were survivors of male-female pairs that had not formed a new pair; prevalence of single-female breeding units was not related to availability of unpaired males. When juvenile survival increased in late autumn, communal groups became the predominant social group. Formation of communal groups was unrelated to low temperatures and was not contingent upon the nonreproductive status of members. Although present at low population density, communal groups were the most common type of social group at high densities. We conclude that increased survival of juveniles in late autumn leads to the formation of communal groups and increases in population density.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many male prairie voles (~35-45%) assume a "wandering" tactic where they acquire large home ranges that overlap territories of one or more "resident" pairs.

    “In addition, though most male prairie voles display a “resident” strategy where they form a pair bond with a female, defend a territory and assist females in the rearing of offspring, many males (~35–45%) assume a “wandering” tactic where they acquire large home ranges that overlap territories of one or more “resident” pairs [57, 58].”
  • "Wanderer" male prairie voles typically only sire offspring via extra-pair fertilizations and provide no care for their young.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
