Data from: Duplication and population dynamics shape historic patterns of selection and genetic variation at the major histocompatibility complex in rodents
Genetic variation at the MHC is vitally important for wildlife populations to respond to pathogen threats. Because natural populations can fluctuate greatly in size, a key issue concerns how population cycles and bottlenecks that could reduce genetic diversity will influence MHC genes. Using 454 seq
Airborne geophysical survey: West Elk Extension, Colorado
Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. In the earlier days of surveying, the only way to represent this data was to generate an analog map with contour lines. This dataset is a representation of the digitiz

Population matrix models for Frasera speciosa from 1974 to 2008
This dataset contains the matrix population models for a population of Frasera speciosa in the Elk Mountains of southwestern Colorado, for the years 1974-2007. Each matrix contains the probability of transitioning from a stage (the column headings) to another stage (the rows) from the starting year

The Timing of maternal behavior of the broad-tailed hummingbird preceding nest failure
Microhabitat selection during nesting of hummingbirds in the Rocky Mountains
The importance of nest location in reducing heat loss by radiation and convection is indicated by a preliminary examination of the nest sites of Broad—tailed and Calliope hummingbirds with regard to chilling nights in the Rocky Mountains. Radiation losses are estimated from surface temperatures. Nes
An estimate of the heat balance of a nesting hummingbird in a chilling climate
Air, nest and body surface temperatures, air velocity, and hemispherical radiation data were used with published values for evaporation and metabolism to estimate the total heat loss of the incubating female when air temperatures were 0–4·6°C.
Physiological ecology of a subalpine dragonfly nymph
Piracy of nesting materials from and by the broadtailed hummingbird
In the course of nesting microclimatic studies of the Broad-tailed Hummingbird (Selusphorus platycercus), I observed three cases of intra-or interspecific piracy of nesting materials. These observations were made in the vicinity of the Rocky Mountain Biological Laboratory, Gothic, Gunnison County, C
