Bee mimicry patterns
Attempts at establishing phenotypic differences in the populations of aspen (<i>Populus tremuloides</i>) at RMBL
Polymorphism in <i>Aquilegia caerula</i>
Mirror-image stimulation applied to field behavior studies
Adaptive significance of pigment polymorphism in Colias butterflies. III. Progress in study of the "alba" variant
The thermal ecology of some Colias butterfly larvae
Density, size and clutch of two high altitude diaptomid copepods
Population characteristics of two copepod species, Diaptomus shoshone Forbes and Diaptomus coloradensis Marsh, and both interspecific and intraspecific interactions are examined. Both species vary in size among years and among several high altitude ponds in Colorado. Larger individuals with larger c
Frequency distribution and linkage disequilibrium of active and null esterase isozymes in natural populations of Drosophila montana
The mode of inheritance of the 15 electrophoretically different α-naphthyl acetate-specific esterases found in five population samples of Drosophila montana collected near Gothic, Colorado, was delineated by mating a strain which exhibited no esterase activity to 237 wild-caught flies, and analyzing
Bird fauna of the vicinity of the Rocky Mountain Biological Laboratory
Enzyme polymorphism and biosystematics: the hypothesis of selective neutrality
In the last few years there has been an explosion of information concerning electrophoretic variation at enzyme loci. These data are being increasingly employed in attempts to elucidate biosystematic and phylogednetic relationships. As the evolutionary role of these allozyme polymorphisms is not wel
Alkaloids and predation patterns in Colorado lupine populations
Hypothermia of broadtailed hummingbirds during incubation in nature with ecological correlations
The first continuous recordings of natural hypothermia, and the only evidences of hypothermia during incubation, were obtained from temperature sensors embedded in synthetic hummingbird eggs placed in the nests. Resorting to this energy-conserving process was infrequent and could be correlated with
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.
