“…Percent of total adult captures that were male-female captures also was higher for prairie voles (15.0%) than for meadow voles (1.5%), as were repeat captures of the same adult male-adult female pair both within and across trapping sessions. These patterns for captures of adult males and adult females are consistent with reports of social monogamy in prairie voles (Ganev et al 2009;Getz et al 1993) and a mating system other than monogamy for meadow voles (Boonstra et al 1993;Madison 1980). Further, 78% of adult male-adult female captures of prairie voles at our alfalfa sites involved individuals from the same social group.…”

“…Data were analyzed using either log linear analysis or chi-square tests of association with Yates correction when appropriate (BMDP version 7.0). To reduce statistical dependence resulting from repeatedly capturing the same individuals over time, Ganev et al (2009) used only the first multiplecapture event for each individual in each of their three selected trapping periods. We had so many multiple captures, often involving numerous individuals, that it was not feasible for us to follow their protocol.…”

“…We had so many multiple captures, often involving numerous individuals, that it was not feasible for us to follow their protocol. Also, Ganev et al (2009) analyzed data collected from trapping on grids within 0.1-ha enclosures. In their study situation, repeated captures of the same individuals likely would be much more common than our trapping of open populations on study grids.…”

“…Because many small mammals are difficult to observe under natural conditions, their social behavior is often inferred from information gathered through live trapping (Ganev et al 2009;Getz et al 1986;Reich and Tamarin 1984). Of particular interest to studies of social behavior are captures of more than one individual in either singlecapture or multiple-capture live traps.…”

“…Direct observations in seminatural environments, together with data gathered through radiotelemetry and live trapping of natural populations, indicate that prairie voles are extremely social, exhibiting extensive maternal and paternal care, monogamy, and a social system based on communal groups (Ganev et al 2009;Getz et al 1993;Gruder-Adams and Getz 1985;McGuire and Novak 1984;Oliveras and Novak 1986). In contrast, laboratory and field data indicate that meadow voles are promiscuous, with males and females nesting separately during the breeding season; males rarely interact with young before weaning but do so to a limited extent after weaning once the female abandons the nest and young (Boonstra et al 1993;Gruder-Adams and Getz 1985;Madison 1978Madison , 1980McGuire and Novak 1984;Oliveras and Novak 1986).…”

Social behavior of small mammals living under natural conditions often is inferred from live-trapping data, particularly from incidents in which two or more individuals are captured together in a trap. We examined whether multiple-capture data from a long-term study of prairie voles (Microtus ochrogaster) and meadow voles (Microtus pennsylvanicus) were consistent with well-known species differences in social behavior (whereas prairie voles are highly social and display monogamy, meadow voles are less social and promiscuous). When possible, we also examined multiple captures of two nontarget species, northern short-tailed shrews (Blarina brevicauda) and western harvest mice (Reithrodontomys megalotis). Percent of total captures that were multiple captures and percent of total adult captures that were male-female captures were highest for prairie voles and lowest for meadow voles; values for harvest mice and shrews were in between those of the vole species, but more similar to values for meadow voles. Repeat captures of the same male-female pair occurred most commonly in prairie voles, and multiple captures of this species typically involved individuals from the same social group. Multiple captures of adults and juveniles were more common in prairie voles than meadow voles, except for captures of at least one adult male and at least one juvenile, which did not differ between the two vole species. Multiple capture data for prairie voles and meadow voles were largely consistent with established species differences in social behavior, suggesting that such data can provide an accurate indication of social and mating systems of small mammals.
