Social Behavior and Population Dynamics of Marmots
This table contains 36 years of demographic data for 12 sites. The trap record for each animal for each year the animal was present includes age, sex, locality, and reproductive status. Also included, when known, are changes in location, fate (predation death, dispersed), and genetic information (al
Social Behavior and Population Dynamics of Yellow-bellied Marmots
This table contains 36 years of trapping data. Up to 12 sites were studied annually within the vicinity of Rocky Mountain Biological Laboratory, Colorado; not all sites were monitored annually. A record includes the location where the subject was trapped, along with its body mass, age, sex, and repr

Temporal separation between philopatric juvenile pikas and their parents limits behavioural conflict
The temporal separation between parents and juveniles appears doubly advantageous in that it allows juveniles to avoid adult aggression and may facilitate their settlement nearby.
Mayfly cerci as defense against stonefly predation: deflection and detection
In situ behavioral experiments were conducted in flow-through observation boxes in a Colorado and a New York stream to compare and contrast the cercal responses of Ephemerellidae and Baetidae mayflies to predaceous stoneflies. Ephemerella infrequens (Colorado) exhibited primarily a posture when touc
Sex differences in the play behavior of yearling yellow-bellied marmots
AbstractPlay in yearling yellow‐bellied marmots (Marmota flaviventris) was studied under non‐manipulative field conditions in the Upper East River Valley of Colorado. The behavior patterns constituting play were described and illustrated and 12 specific hypotheses related to sex differences were tes
