Effects of snowpack on the timing and abundance of flowering in Delphinium nelsonii: implications for climate change
Delphinium nelsonii is an early‐blooming herbaceous perennial of montane western North America, which we studied in dry subalpine meadows in the Colorado Rocky Mountains. We examined the effects of variation in annual snowfall between 1973 and 1989 on the timing and abundance of flowering. During ye
The effect of floral abundance on feeder censuses of hummingbird populations
Numbers of Broad-tailed Hummingbirds (Selasphorous platycercus) captured each summer from 1979-1989 at the Rocky Mountain Biological Laboratory were quite variable, ranging from 115 (1981) to 348 (1989), with new birds usually outnumbering returning (previously banded) birds. Capture numbers were ne
Intraventricular insulin reduces food intake and body weight of marmots during the summer feeding period
It is suggested that during the summer when marmots are not hibernating and are actively feeding, brain insulin levels may play a role in regulating food intake.
Seasonal changes in CSF insulin concentrations in marmots: insulin may not be the satiety signal for fasting in winter

Determinants of spatial distribution in a population of the subalpine butterfly <i>Oeneis chryxus</i>
Effects of floral traits on sequential components of fitness in Ipomopsis aggregata
The total number of viable, undamaged seeds released by a plant provides an estimate of female reproductive success (RS). I outline a method for analyzing pollinator-mediated selection based on partitioning female RS into four multiplicative components: number of flowers, pollen received per flower,

Western Slope Energy Research Center 1980 Annual Report
In some ways 1980 has been a rather discouraging year. Colorado- Ute and ARCGo both disclosed plans for growth which would have considerable impact on Delta County. O11 Shale in the northwestern part of the state is rushing ahead. and the election results do not look promising for environmental caus
