Data files and publications of a 25 year and 63 month study of populations of the prairie and meadow voles
(Current Zoology, 2005)We summarize the social organization and mating system of the prairie vole Microtus ochrogaster as determined from an extensive field study in east-central Illinois, USA. The fundamental social organization of M. ochrogaster ...
Does mate choice take place in free-living prairie voles Microtus ochrogaster? Evidence from field data (Current Zoology, 2004)We used live-trapping data collected during a long-term study of the social organization of prairie vole Microtus ochrogaster, to investigate pair formation and break-up in this species. Most male-female pairs that formed ...
(Illinois State Academy of Science, 1987)Rarity of the blonde color morph in prairie vole populations is attributed to: a recessive trait requiring breeding between siblings or parents and their offspring for the color morph to be prominent within a population; ...
The chemistry of child neglect: Do oxytocin and vasopressin mediate the effects of early experience? (The National Academy of Sciences, 2005-12-20)Research described in a recent issue of PNAS by Wismer Fries, Ziegler, Kurian, Jacoris, and Pollak (1) reveals significant group differences in two brain-derived neuropeptides, oxytocin and vasopressin, between family- ...
(The National Academy of Sciences, 1999-10)Although the biological roots of aggression have been the source of intense debate, the precise physiological mechanisms responsible for aggression remain poorly understood. In most species, aggression is more common in ...
