1. Establishing trade-offs among traits and the degree to which they co-vary along environmental gradients has become a key focal point in the effort to develop community ecology into a predictive science. While there is evidence for these relationships across global datasets, they are often too bro

Many woody plants resprout to restore above-ground biomass after disturbances or to survive in stressful environments. Resprouting requires carbohydrate storage, but the general relationship between resource allocation patterns and resprouting ability remains unclear because it can be influenced by

Genetic variability at 27 loci was analyzed in four populations of pikas (Ochotona princeps) from Colorado. Estimates of mean heterozygosity [Formula: see text] ranged from 0.5 to 1.4%. These results are among the lowest estimates of [Formula: see text] reported for a mammal having a broad distribut

In bumblebee visits to flowers of Erythronium grandiflorum (Liliaceae), the ratio of self‐ to nonself‐ (“outcross”) pollen grains deposited on the stigma is positively correlated with the degree of stylar exsertion beyond the anthers. Natural populations show substantial, continuous variation in sty

For a brief period in 1981 Bombus appositus queens visited Ipomopsis aggregata, a hummingbird-pollinated species with floral characteristics typical of that pollination syndrome. This behavior was not observed in other years. Despite the fact that Ipomopsis lacks floral features associated with bee

Behavioral experiments were carried out in flow-through observation boxes in New York and Colorado streams to determine whether interactions between pairs of predaceous stoneflies were characterized by exploitative or interference competition and to determine the effect of prey density on such inter

Experiments in Colorado and New York streams assessed the effects of predaceous stoneflies on benthic invertebrate community establishment in enclosures providing uncolonized habitat. Aspects of prey community structure measured were density, species richness, relative species abundance, and body si

A major link between larval ecology and mating systems in butterflies is the environment in which larvae hatch. It determines when a female should lay her eggs, and therefore when she will be receptive to mating. The fitness of males is determined chiefly by access to fertilizable females, and there

Sympatric plant species can compete for pollination services in several ways. For example, pollinators may move between species and deposit heterospecific pollen on stigmas, which in turn may reduce the efficacy of conspecific pollen. We explored this possibility by determining the effect of Delphin

Model and experimental results suggest that, in certain wing regions, increased melanization can reduce body temperature in Pieris; this effect of melanization is exactly the opposite of that found in other Pierid butterflies that use their wings as solar absorbers.
