data of vouchered bees to test for differences between repeatedly sampled sites and single sample sites regarding abundance (as catch rate), rarefied richness, and evenness (as Evar).

data of combined bees (vouchered + released) to test for differences between repeatedly sampled sites and single sample sites regarding abundance (as catch rate), rarefied richness, and evenness (as Evar).

data of vouchered bees to test for differences between repeatedly sampled sites and single sample sites regarding abundance functional group composition. The four functional groups tested were diet (lecty), sociality, body size (size), and nesting substrate (nesting). Note that sociality was tested

The impact of a native, leaf—feeding chrysomelid beetle (Phaedon sp. nr. oviformis) on bittercress (Cardamine cordifolia: Cruciferae), was evaluated in an exclusion experiment. Multivariate statistical analysis showed a significant increase in plant performance in the rotenone exclusion compared to

To explore mechanistic constraints on the evolution of optimal phenotypes, we develop an optimality model for thermoregulation in Colias butterflies. The model identifies the thermoregulatory characteristics of butterflies that maximize time available for flight activity subject to an overheating co

Mark-recapture data indicate that daily population sizes are low, most adults remain in residence at the colony only a few days, and there are age-specific sexual differences in movement, with older females perhaps leaving the colony site.

Plasma melatonin concentrations were measured throughout bouts of hibernation in marmots maintained in a short photoperiod (light-dark 8:16) and ambient temperature of 5 or 15 degrees C. Melatonin concentration was also measured in two animals maintained in constant darkness. As an animal entered hi

Counts of montane Euphydryas editha along transects at Almont Summit, Colorado, show that males form a dense aggregation along a ridgetop with an estimated 30:1 (male:female) sex ratio. Fertilized females showed preference for subsites below the ridgetop at least as rich in oviposition plants but le
