Phenotypic variation and aposematic signaling in an arctiid moth (Utetheisa ornatrix)
Meeting Abstract 88-3 Saturday, Jan. 7 10:45 – 11:00 Phenotypic variation and aposematic signaling in an arctiid moth (Utetheisa ornatrix) GAWNE, R*; NIJHOUT, HF; Duke University; Duke University richard.gawne@duke.edu The bella moth Utetheisa ornatrix (Lepidoptera:Arctiidae) sequesters pyrrolizidine alkaloids from host plants during its larval stage. Adults are diurnal, and previous studies have suggested that they visually signal their distastefulness to […]

Previous work has documented […]
Some don’t like it hot Variation in stingless bee flight performance as a function of air temperature
Meeting Abstract 87-1 Saturday, Jan. 7 10:15 – 10:30 Some don’t like it hot: Variation in stingless bee flight performance as a function of air temperature DUELL, ME*; HARRISON , JF; Arizona State University meduell@asu.edu Environmental temperatures strongly affect the fitness of ectotherms, but these effects depend on body size. The “temperature-size rule” describes the pattern that […]

For butterflies from temperate regions, distinct seasonal morphs adapt to specific […]
Molecular targets of thermal stress during early development in Drosophila melanogaster
Meeting Abstract 87-6 Saturday, Jan. 7 11:30 – 11:45 Molecular targets of thermal stress during early development in Drosophila melanogaster LOCKWOOD, BL*; GUPTA, T; University of Vermont Brent.Lockwood@uvm.edu http://www.uvm.edu/~bllockwo/ The effects of temperature on physiological processes are ubiquitous. However, to a large extent, the effects of thermal stress on developmental processes during early life stages have not […]
