FASTA file of 21 MHC Class II Mimo-DRB alleles recovered from a wild population of montane vole (Microtus montanus). Samples were obtained between 2008-2010 near the Rocky Mountain biological Laboratory, located in the Upper East River Valley, CO (39N, 107W).

Evaluation of genetic differentiation within the Sage-grouse genus Centrocercus. Three geographically distinct samples of North American Sage-grouse, genus Centrocercus (class Aves). Two samples are taxonomically considered Greater Sage-grouse (Centrocercus urophasianus) and the third is considered

Identification of the causal genes that control complex trait variation remains challenging, limiting our appreciation of the evolutionary processes that influence polymorphisms in nature. We cloned a quantitative trait locus that controls plant defensive chemistry, damage by insect herbivores, surv

Fitness trade-offs across episodes of selection and environments influence life-history evolution and adaptive population divergence. Documenting these trade-offs remains challenging as selection can vary in magnitude and direction through time and space. Here, we evaluate fitness trade-offs at the

Differences in foraging behavior observed on two plant species with similar floral and inflorescence structures increase the neighborhood size for nectar producing species and make it increasingly unlikely that random drift will be a dominant mode of evolution in populations of these species.

Overlaps in resource use have been used to summarize community structure. It is ofen desirable to compare the amount of intensity of overlaps (or other pairwise measures such as competition coefficients) in different communities, especially in the context of comparing actual communities to "neutral

There is no evidence that flight characteristics depend on anything as straightforward as whether flower visitors have high or low energetic requirements, and all the visitors to a given plant species fly similar, short distances between successively visited flowers and plants.

Most aspects of the bumblebees' rule of departure from an inflorescence of Aconitum columbianum are qualitatively what would be expected if the bumblebees maximize their net rate of energy gain. Flower revisitation increases with increases in the number of flowers already probed on an inflorescence

It was hypothesized that the local geographic distributions of bumblebees near Crested Butte, Colorado and the community patterns exhibited by these bumblebees are the products of competition for plants. To evaluate this hypothesis several transects were established and at regular intervals througho

It is concluded that presence of pollen on recipient flowers significantly reduces the average number of subsequent flowers reached by donor pollen.

Aquatic insects have numerous adaptations reflecting the coevolution of predators and prey. Predators have a wide variety of search, capture, and consumption mechanisms, and prey demonstrate various physical, chemical, and behavioral defenses. Mortality in prey populations from predation may be sign

The success of the butterfly simulator in mimicking Colias thermal characteristics confirms the preliminary understanding of the physical bases for and heat transfer mechanisms underlying thermoregulatory adaptations in these butterflies.
