Snow-free Growing Degree-days 0-60 Days Post Snow Standard Deviation (2002-2021)
This is a map of temporal variability in accumulated snow-free growing potential (snow-free growing degree days, SFGDD) for the Upper Gunnison domain, derived from daily maximum temperature maps interpolated from weather station and microclimate sensor data combined with Landsat-derived estimates of
Snow-free Growing Degree-days 0-60 Days Post Snow Mean (2002-2021)
This is a map of accumulated snow-free growing potential (snow-free growing degree days, SFGDD) for the Upper Gunnison domain, derived from daily maximum temperature maps interpolated from weather station and microclimate sensor data combined with Landsat-derived estimates of the timing of seasonal
Patterns of rust infection as a function of host genetic diversity and host density in natural populations of the apomictic crucifer, <i>Arabis holboellii</i>
It is often assumed that genetic diversity contributes to reduced disease incidence in natural plant populations. However, little is known about the genetic structure of natural populations affected by disease. Here I present data from three apomictic (asexual) populations of Arabis holboellii infec
Floral mimicry by a plant pathogen
An extraordinary case of pathogen-mediated floral mimicry that contributes to fungal reproduction of the rust fungus Puccinia monoica is reported.
Differential success of pollen donors in a self-compatible lily
Factors affecting pollinator visitation rates: a biogeographic comparison
Sublethal consequences of stream-dwelling predatory stoneflies on mayfly growth and fecundity
Predators can have consequences on prey populations and communities that extend well beyond direct predator—induced mortality. Predator—prey interactions often affect prey feeding rates, growth rates, or fecundities, thereby significantly affecting reproductive success of prey adults. Thus, investig
Comparison between plant species in bushy-tailed woodrat middens and in the habitat
Parentage analysis in ant colonies using simple sequence repeat loci
Birding for fun: Sapsuckers, swallows, willow, aspen and rot
Geitonogamy: the neglected side of selfing
Selfing by geitonogamy incurs a fitness cost of reduced pollen export, and recent reports show that seed set can suffer as well, even in self-incompatible species.
Double keystone bird in a keystone species complex
Species in a Colorado subalpine ecosystem show subtle interdependences. Red-naped sapsuckers play two distinct keystone roles. They excavate nest cavities in fungus-infected aspens that are required as nest sites by two species of swallows, and they drill sap wells into willows that provide abundant
Heartwood decay and vertical distribution of red-naped sapsucker nest cavities
Microclimate amelioration may be critical to recovery of subalpine ecosystems (Colorado)
Hypothesis concerning the causes of the disappearance of boreal toads from the mountains of Colorado
Recent reports of world‐wide declines and extinctions of amphibian populations have raised questions about the relation of environmental change to the demise of certain amphibian species. Between 1974 and 1982, 11 populations of boreal toads ( Bufo boreas boreas ) in the West Elk Mountains of Colora
Resource and pollen limitations to lifetime seed production in a natural plant population
Using experimental manipulations, we examined pollen and resource limitations to seed production and their interaction in a natural population of a monocarpic plant, Ipomopsis aggregata. Our design cross two factors, pollen level (hand—pollinated or control) and resource level (water added, water an
