Searching in a patchy environment: food plant selection by Colias p. eriphyle butterflies
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
Experimental studies of pollen carryover: hummingbirds and Ipomopsis aggregata
It is concluded that presence of pollen on recipient flowers significantly reduces the average number of subsequent flowers reached by donor pollen.
Aquatic insect predator-prey relations
Aquatic insects have numerous adaptations reflecting the coevolution of predators and prey. Predators have a wide variety of search, capture, and consumption mechanisms, and prey demonstrate various physical, chemical, and behavioral defenses. Mortality in prey populations from predation may be sign
Some energetic aspects of behavior in a montane hummingbird nesting habitat
Kinship, reproductive strategies, and social dynamics of yellow-bellied marmots
Social behavior of yellow-bellied marmots was observed for three years in colonies where kinship was known and for one year in a high elevation colony where harems were contiguous, indicating that reproductive strategies limit nepotism.
Social dynamics of juvenile marmots: role of kinship and individual variability
A population of eight juvenile female yellow-bellied marmots was introduced into a marmot locality from which all other marmOTS were removed and the individual behavioral profile of each animal was determined by mirror image stimulation.

Feeding habits and prey consumption of three predaceous stoneflies (Plecoptera) in a mountain stream
The feeding ecology of predaceous stoneflies was investigated over 18 mo in Cement Creek, Colorado, USA. Three species were studied at each of three sites over their entire life cycles to elucidate any differences due to species and site. Diet typically changed, over the course of development, from
The effects of reduction in trout density on the invertebrate community of a mountain stream
An experimental reduction in trout density was carried out for 4 yr to determine whether the numbers or species composition of aquatic invertebrates would be affected. In a Colorado stream, the standing crop of trout (mainly Salvelinus fontinalis) prior to this study was 4.86 g/m2, typical of infert
