Migration Stopovers (WGFD) of Mule Deer in the Platte Valley Herd in Wyoming
The Platte Valley Herd Corridor was designated by the Wyoming Game and Fish Department in 2018 (fig. 30). The Platte Valley herd contains approximately 11,000 mule deer. The corridor is based on two wintering populations, including a south segment from Saratoga, Wyoming, to the Colorado State line,
Data release for Geologic Map of the Homestake Reservoir 7.5' quadrangle, Lake, Pitkin, and Eagle Counties, Colorado
The Homestake Reservoir 7.5' quadrangle lies at the northwestern end of the Upper Arkansas Valley, and headwaters of the Arkansas River, and the Roaring Fork, Fryingpan, and Eagle Rivers of the Colorado River system. The quadrangle lies within tectonic provinces of the 1.4 Ga Picuris Orogeny, the la
Ute Ulay Water Tank
The Ute Ulay Mining Complex is located along the Alpine Loop Scenic Byway just south of Lake City, Colorado. The Ute Ulay mining claims were discovered in 1871 and were one of the biggest producers of gold and silver in the San Juan Mountains. The Bureau of Land Management Gunnison Field Office has

The effect of experimental ecosystem warming on CO2 fluxes in a montane meadow
AbstractClimatic change is predicted to alter rates of soil respiration and assimilation of carbon by plants. Net loss of carbon from ecosystems would form a positive feedback enhancing anthropogenic global warming. We tested the effect of increased heat input, one of the most certain impacts of glo
Rapid size-specific changes in the drift of <i>Baetis bicaudatus</i> (Ephemeroptera) caused by alterations in fish odour concentration
Criteria determining behavioural responses to multiple predators by a stream mayfly
McIntosh. A. R. and Peckarsky, B. L. 1999. Criteria determining behavioural responses to multiple predators by a stream mayfly - Oikos 85: 554-564. We investigated prey responses to multiple predators by observing drift and positioning of Buetis bicuudctrus (Ephemeroptera: Baetidae) nymphs in the pr
Three Harpellales that live in one species of aquatic chironomid larva
Two new species of harpellid gut fungi, Smittium fecundum and Stachylina robusta, were found living in larvae of Psectrocladius sp. (Diptera: Chironomidae) in a high-altitude kettle pond in the Rocky Mountains of Colorado. A third species of Harpellales, Smittium mucronatum, previously known only fr
Nectar-robbing bumble bees reduce the fitness of <i>Ipomopsis aggregata</i> (Polemoniaceae)
Estimating species-area relationships from plot to landscape scale using species spatial-turnover data
John Harte, Sarah McCarthy, Kevin Taylor, Ann Kinzig, Marc L. Fischer, Estimating Species-Area Relationships from Plot to Landscape Scale Using Species Spatial-Turnover Data, Oikos, Vol. 86, No. 1 (Jul., 1999), pp. 45-54
The role of urine marking in the foraging behavior of least chipmunks
Flower constancy, insect psychology, and plant evolution
The way in which floral parameters, such as interplant distances, nectar rewards, flower morphology, and floral color affect constancy is considered, and the implications of pollinator constancy for plant evolution are discussed.
Pollination of <i>Ipomopsis aggregata</i> (Polemoniacea): Effects of Intra-vs. Interspecific competition
Scent-marking in the yellow-bellied marmot <i>Marmota flaviventris</i>
Cheek-marking in yellow-bellied marmots (Marmota flaviventris) was studied by observations of cheek-marking in two colonies from 10 June to 6 August, 1996 and by experimental studies of responses to olfactory secretions from the perioral gland. The rate of cheek-marking declined significantly as the
Effects of Local Density on Pollination and Reproduction in <i>Delphinium nuttallianum</i> and <i>Aconitum columbianum</i> (Ranunculaceae)
Plant populations vary in density both naturally and as a consequence of anthropogenic impacts. Density in turn can influence pollination by animals. For example, plants in dense populations might enjoy more frequent visitation if pollinators forage most efficiently in such populations. We explored
Dispersal of the fairy shrimp <i>Branchinecta coloradensis</i> (Anostraca): Effects of hydroperiod and salamanders
The absence of fairy shrimp (Anostraca) from permanent ponds and lakes is hypothesized to be the result of vertebrate predation. However, hatching cues for anostracan diapausing eggs include factors associated with the filling of temporary pond basins, and desiccation often increases the fraction of
