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

Data come from fourteen sites in the West Elk Mountains of Colorado, USA. The study aimed to identify the factors regulating phenology of plants and cavity-nesting insects, and to determine the likelihood of asynchrony between flowering and pollinator emergence under climate change. Numbers of flowe

Prof. David Inouye has been collecting data on the abundance and timing of flowers that fall within permanent plots at the Rocky Mountain Biological Laboratory (RMBL), in Gothic, Colorado, USA, from 1973 to present. During the growing season, flowers of each species are counted approximately every o

Prof. Rebecca (Becky) Irwin has been collecting data on the abundance and timing of bees in permanent sites near the Rocky Mountain Biological Lab (RMBL), Gothic, Colorado, USA, from 2009 to present. During the flight season, we use pan traps and netting every two weeks to estimate bee abundance by

This file contains data on the frost damage of eight subalpine plant species from the Rocky Mountains of Colorado (USA). These frost damage data can be used to calculate frost sensitivity for each species. Frost damage of plant tissue was determined after specimen were exposed to experimental temper

These data have been collected by David Inouye almost every year since 1973 at the Rocky Mountain Biological Laboratory, Gothic, Colorado, altitude about 2890.4 meters (9483 feet).
