Average 2m Air Temperature Monthly Timeseries
These are maps of monthly averages of daily average air temperature for the Upper Gunnison domain measured in degrees C. Estimates were derived from weather station and microclimate sensor data using Bayesian regression-kriging, incorporating topographic and vegetation structure covariates. These da
Minimum 2m Air Temperature Daily Timeseries
These are maps of daily minimum air temperature for the Upper Gunnison domain measured in degrees C. Estimates were derived from weather station and microclimate sensor data using Bayesian regression-kriging, incorporating topographic and vegetation structure covariates. To reduce storage space, ori
Resource allocation to oocytes: heritable variation with altitude in Colias philodice eriphyle (Lepidoptera)
This study tests the hypothesis that selection should result in a positive correlation between numbers of oocytes produced and available oviposition time, in order to avoid wasting nutrients through the formation of unused oocytes in Colias philodice eriphyle Edwards.
Lycaenid butterflies and ants: two species stable equilibria in mutualistic, commensal, and parasitic interactions
The selective advantage of attendant ants for the larvae of a lycanaenid butterfly, Glaucopsyche lygdamus
Colonization of natural substrates by stream benthos
Natural substrates in mesh cages in a Tompkins County, New York, woodland stream were colonized by benthic invertebrates for periods of 3, 6, 9, 12, 18, 24, 30, and 42 d during autumn 1980. An experiment was designed for the purpose of distinguishing seasonal phenology from site-specific temporal (n
Long-term preformation of leaves and inflorescences by a long-lived perennial monocarp, Frasera speciosa (Gentianaceae)
In Frasera speciosa , a long‐lived monocarpic gentian from the Colorado Rocky Mountains, leaves are preformed two to three yr in advance of their appearance above ground. Initiation of a flower stalk may begin as long as three yr before it becomes fully developed during a plant's final year. Whorls
Insect herbivory in response to root-cutting and flooding stress on a native crucifer under field conditions
Foraging behavior of the pika (<i>Ochotona princeps</i>), with comparisons of grazing versus haying
Dual function of the eliasome of <i>Corydalis aurea</i> (Fumariaceae): attraction of dispersal agents and repulsion of <i>Peromyscus maniculatus</i>, a seed predator
It has been suggested that one of the selective advantages of ant dispersal is the burial of seeds in ant nests where predators such as small rodents cannot find them. The elaiosomes of Corydalis aurea (Fumariaceae) are extremely attractive to ants, which assiduously gather the seeds and take them t
Pancreatic A and B cell stimulation in euthermic and hibernating marmots (<i>Marmota flaviventris</i>): effects of glucose and arginine administration
Non-adaptive" hilltopping behavior in male checkerspot butterflies (Euphydryas editha)
A fluorescent-dye technique permitted the mating success of male checkerspot butterflies aggregating on a ridge to be compared with that of males on the slope below. Unexpectedly, the males on the ridge had about one-half the mating success of those on the slope. We suggest that formation of this an

Tolerance of Variation in Eggshell Conductance, Water Loss, and Water Content by Red-Winged Blackbird Embryos
This study evaluated the relations between eggshell conductance to water vapor ($$G_{H_{2}O}$$), daily water loss ($$\dot{M}_{H_{2}O}$$), embryonic water content near pipping, and hatching success in red-winged blackbird eggs under conditions of natural incubation. All embryos hatched successfully o

Individual differences in the behavior of juvenile yellow-bellied marmots
Yellow-bellied marmots express considerable individuality as measured by behavior in a maze, mirror-image stimulation (MIS), and social behavior in the field, suggesting that marmot have individual behavioral phenotypes that are expressed in their social interactions with their conspecifics.
