Snow-free Freezing Degree-days Annual Standard Deviation (2002-2021)
This is a map of temporal variability in accumulated snow-free freezing potential (freezing degree days, FDD) for the Upper Gunnison domain, derived from daily minimum temperature maps interpolated from weather station and microclimate sensor data combined with Landsat-derived estimates of the timin

Heterogeneity among floral visitors leads to discordance between removal and deposition of pollen
Flowers are often visited by many species of animals. \nThese sometimes differ in size, behavior, and other \ncharacteristics that translate into differences in their effectiveness as pollinators. The differences \nmay be manifest in their effect on reproductive \nsuccess either thro

Reproductive costs of self-pollination in Ipomopsis aggregata: are ovules usurped?
In common with many cosexual angiosperms, the hummingbird‐pollinated montane herb Ipomopsis aggregata (Polemoniaceae) is likely to experience self‐pollination. Does this incur a fecundity cost even in such a highly self‐sterile (presumably self‐incompatible) species? Histological studies showed that
Outcrossing distance effects in <i>Delphinium nelsonii</i>: pollen loads, pollen tubes, and seed set
Duration of snow cover and its influence on life-history variation in yellow-bellied marmots
We evaluated the relationship between growing-season phenology, as indicated by time of snow melt, and intrapopulation variation in reproduction and growth of yellow-bellied marmots. The time of snow melt explained significant proportions of the variation in frequency of reproduction (78%), litter s
Yellow-bellied marmots as prey of coyotes
-Analysis of contents of 395 coyote (Canis latrans) scats collected for 6 yr at a subalpine locality in Colorado showed that yellow-bellied marmots (Marmota flaviventris) were a regular and frequent prey of coyotes during summer. There was no evidence that marmots were especially vulnerable to preda
