In an outdoor garden at Irwin, Colorado, we established glacier lily plants in open-bottomed PVC pots that protected them from gopher attack. The initial cohorts were excavated from field sites as mature corms of unknown age. Later cohorts were grown from seed, so their ages are known. Each spring s

Here, we deposit data from a vegetation survey conducted in 2014. The data was collected to document current vegetation patterns in the region, parameterize species distribution models, and assess community turnover in flower color. The survey was conducted in the Upper Gunnison Basin and the enviro

Broad‐tailed and rufous hummingbirds avoid plants and flowers that have recently been visited by nectar‐robbing bees. However, the cues the hummingbirds use to make such choices are not known. To determine the proximate cues hummingbirds use to avoid visiting nectar‐robbed plants, I conducted multip

We examined the roles of floral scent and color in attracting bumblebees (Bombus spp.) to snapdragon flowers (Antirrhinum, Sonnet cultivar). Corolla color differences covaried with differences in floral scent emissions in two inbred lines of snapdragon. White-flowered plants emitted methyl cinnamate

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.

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
