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).

It is stressed that chemotactile cues are involved only in the final step of oviposition, and that understanding foodplant choice in nature will require in-depth investigation into the mechanics of individual search processes.

It is suggested that outbreeding depression will often occur on a much finer scale than previously recognised, especially in plants subject to restricted pollen and seed dispersal, and a short outcrossing distance is optimal for Delphinium nelsoni Greene.

It is hypothesized that nectar-collecting bumblebees will be found to forage in ways that maximize their net rate of energy intake, and the manner in which they move from one flower to another within inflorescence is focused on.

The dispersion pattern of resources in a population of Delphinium nelsonii showed that subject plants and their neighbors were likely to have the same “temperature”, indicating that resources were patchy.

Stainless steel screen cages were buried in the substrate of Otter Creek, Wisconsin, during spring 1976 and 1977 and the East River, Colorado, during summer 1977 and stocked with known densities of benthos, Cages were retrieved after 3 days of colonization and attrition from a given direction and sp

Environmental parameters, population dynamics, resource utilization patterns, and social dynamics were evaluated in terms of their relationships to population density, intraspecific competition, parent—offspring relations, and male territoriality.

Standard metabolic rates (SMR) of boreas and halophilus show pronounced regions of thermal independence but all other standard and active metabolic rates of groups acclimated to other thermal regimes are thermally sensitive.
