Oviposition Behavior of <i>Hylemya</i>(Delia)sp. (Diptera:Anthomyiidae): Suboptimal Host Plant Choice?
Short-term learning and the searching accuracy of egg-laying butterflies
Two interpretations are presented: (1) that partitioning searching time into discrete modes may enhance overaccuracy in invertebrates, as has been demonstrated previously for vertebrates and (2) that search dynamics of this type may explain some discrepancies between the predictions made by simple o
Spatial relationships and social organization in adult pikas: a facultatively monogamous mammal
Abstract and SummaryAdult spatial relationships and social organization in a marked population of alpine mammals, the pika (Ochotona princeps), were studied over a 3‐year period in the Rocky Mountains of Colorado. Home range size, distances between centers of activity of dyads, and weighted overlaps
The effects of capturing and marking on subsequent activity in <i>Boloria acrocnema</i> (Lepidoptera: Nymphalidae), with a comparison of different numerical models that estimate population size
Foraging patterns of yellow-bellied marmots: role of kinship and individual variability
Plasma melatonin rhythms in euthermic marmots (<i>Marmota flaviventris</i>)
Plasma melatonin concentrations in hibernating marmots: absence of a plasma melatonin rhythm
Plasma melatonin concentrations were measured throughout bouts of hibernation in marmots maintained in a short photoperiod (light-dark 8:16) and ambient temperature of 5 or 15 degrees C. Melatonin concentration was also measured in two animals maintained in constant darkness. As an animal entered hi

Hadrosaur Locomotion and Herding Behavior: Evidence from Footprints in The Mesaverde Formation, Grand Mesa Coal Field, Colorado
Dinosaur footprint casts from a Mesaverde (Campanian) coal mine near Gunnison, Colorado resemble those of the notorious "mystery dinosaur, Xosaurus" which was probably a giant hadrosaur. Existing footprint descriptions, although obscure and hard to verify, are too important to overlook, particularit
Spatial and Behavioral Foraging Patterns and Diet Selectivity in the Social Yellow-Bellied Marmot
A comparison of the effects of predispersal seed predation on seed set of three Rocky Mountain plant species in the sun and shade
Aqueous geochemical dynamics of metals and rare earth elements in an acid rock drainage-impacted alpine watershed
Numerous mountain watersheds in the Colorado Mineral Belt (CMB) are impacted by acid rock drainage (ARD) and acid mine drainage (AMD), which mobilize metals and rare earth elements (REEs) into surface waters. In the upper Roaring Fork watershed near Independence Pass, natural ARD from a highly miner
