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

Social Behavior and Population Dynamics of Marmots
This table contains 37 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

Optimal foraging: a case for random movement
It is shown that B. flavifrons is using the resource distribution to direct its movements, and a large percentage of all movements are to nearest neighbors with maximal foraging efficiency gained through minimization of flight distances.
Oviposition behavior and the existence of an oviposition-deterring pheromone in Hylemya
Effective mutualism between sequentially flowering plant species
Evidence is presented that effective mutualism occurs between two species which also compete for pollination and which act as mutualistic partners at the same time that their sequential flowering is maintained by competition.
