Arthropod abundance censused on the host plant Ligusticum porteri near Gothic, CO.
The objective of this study is to understand how climate cues affect the abundance and phenology of aphids and the arthropods with which they interact. These data were collected in 20 populations of the host plant (Ligusticum porteri) along an elevation gradient near Gothic, CO, USA. We randomly-sel
Sub-Basin Delineation for the Upper East River, Colorado, United States.
Upper East sub-basins are delineated as area contributing flow to SFA 2016 stream gage locations. Shapefile attributes include sub-basin ID, name, area (m2 and km2) and codes for spatial contributions to EBC and PH used by Carroll et al. (2018). Geospatial reference is UTM 1983 zone 13.

Competition among pollinators: quantification of available resources
In a study of the bee community of short-grass prairie Tepedino and Stanton (1981) attempted to verify several predictions of competition theory by comparing abundances of bees and flowers. Their results were inconclusive suggesting, they said, that bees do not continuously compete for floral resour
Optimal foraging: random movement by pollen collecting bumblebees
The data indicate that bumblebees exhibit great plasticity in foraging behavior and that they are able to forage efficiently under a wide range of environmental conditions.

The effect of nectar production on neighborhood size
Differences in foraging behavior observed on two plant species with similar floral and inflorescence structures increase the neighborhood size for nectar producing species and make it increasingly unlikely that random drift will be a dominant mode of evolution in populations of these species.

A comparison of distances flown by different visitors to flowers of the same species
There is no evidence that flight characteristics depend on anything as straightforward as whether flower visitors have high or low energetic requirements, and all the visitors to a given plant species fly similar, short distances between successively visited flowers and plants.

Foraging in bumblebees: rule of departure from an inflorescence
Most aspects of the bumblebees' rule of departure from an inflorescence of Aconitum columbianum are qualitatively what would be expected if the bumblebees maximize their net rate of energy gain. Flower revisitation increases with increases in the number of flowers already probed on an inflorescence
Local geographic distributions of bumblebees near Crested Butte, Colorado: competition and community structure
It was hypothesized that the local geographic distributions of bumblebees near Crested Butte, Colorado and the community patterns exhibited by these bumblebees are the products of competition for plants. To evaluate this hypothesis several transects were established and at regular intervals througho
