This is a map of various vegetation canopy structure metrics derived from high-density airborne LiDAR scans collected in August - September 2015 and 2019. The different raster bands represent statistical summaries of the normalized LiDAR point cloud. In the normalized point cloud, ground elevations

This map represents the estimated on-road and off-road travel time in minutes from Crested Butte via the fastest travel means available (snowmobiles excluded). Estimates apply for winter (snow-on) conditions. This map was generated with the cost distance GRASS GIS module (r.cost) using estimated tra

This map represents the estimated on-road and off-road travel time in minutes from Crested Butte via the fastest travel means available (snowmobiles excluded). Estimates apply for summer (snow-off) conditions after all roads have been opened to vehicle traffic. This map was generated with the cost d

This is a visible (RGB) orthomosaic derived from UAV imagery via Structure from Motion processing. UAV flights were performed in sunny conditions on May 25th 2019, collecting RGB images using the built-in camera on a DJI Mavic 2 Pro. The raw imagery had an approximately 3cm ground sample distance (G

Previous studies have shown that chemical cues from brook trout (Salvelinus fontinalis) induce relatively longer caudal filaments and heavier exoskeletons in the mayfly Drunella coloradensis. These characters constitute morphological defences that reduce larval mortality from brook trout predation.

Many organisms living in heterogeneous environments alter behaviors or morphology when developing in the presence of predators and subsequently incur associated sublethal fitness costs. Larvae of the mayfly Callibaetis ferrugineus hageni develop in beaver ponds with or without trout predators. We ex

Dispersal among spatially subdivided populations and variability in local habitat patch quality can strongly affect local and regional population dynamics. A metapopulation of mayflies (Callibaetis ferrugineus hageni) was studied in which larvae developed in beaver ponds and emerged to the terrestri

Dispersal affects a wide array of ecological and evolutionary processes, but has been difficult to estimate empirically. A 15 Nitrogen stable isotope enrichment technique was used to passively mark all developing Callibaetis ferrugineus hageni (Eaton) mayfly larvae in a beaver pond that had previous

Abstract I studied the relationships among energy availability, female visitation rates, and male display rates in Broad-tailed Hummingbirds (Selasphorus platycercus). Feeders contained 10%, 20%, or 30% sucrose solutions; female visitation rates and male hummingbird display rates were measured. Disp

Abstract One cause of reproductive isolation is gamete competition, in which conspecific pollen has an advantage over heterospecific pollen in siring seeds, thereby decreasing the formation of F1 hybrids. Analogous pollen interactions between hybrid pollen and conspecific pollen can contribute to po

We explored the relative importance of temporal vs. spatial variability to the conditionality of a mutualism between the treehopper Publilia modesta and the ant Formica obscuripes. The effect of the ants on the membracids varied considerably among years. When the effect of the ants on the membracids

Abstract. 1. Patterns of worker demography in the ant Formica neorufibarbis were documented under natural conditions. 2. Some workers lived at least 4 years. 3. In 4 of 5 years, colonies were more likely to retain older workers than new workers. 4. Workers persisted for more years in colonies lackin

Mirror-image stimulation (MIS) was used to determine the individual behavioral phenotypes of 90 adult, 132 yearling, and 135 young yellow-bellied marmots (Marmota flaviventris). Linear typal analysis (LTA) was used to group individuals based on similarities in their MIS scores. Principal component a
