The role of environmental heterogeneity in the evolution of life history strategies of the striped ground cricket /Bradford, Michael J. January 1991 (has links)
I examined the effect of heterogeneity in the thermal environment on the life history of the cricket Allonemobius fasciatus. Variation in the life cycle was the result of a mixture of phenotypic plasticity and genetic differentiation in phenology-related traits along a latitudinal cline in growing season. Females from a partially bivoltine population have a conditional life history because they can adjust the proportion of diapause eggs in accordance with the likelihood that a second generation will grow and reproduce before winter. The thermal environment is not variable enough to result in the evolution of a marked bet hedging response, as is predicted by theory. A quantitative genetic analysis of the diapause reaction norm revealed significant heritabilities as well as correlations with other traits that could be related to common physiological mechanisms.

The effect of temperature on the life cycle of Drosophila acutilabellaMiles, Donald A. 01 January 1981 (has links)
This is a study of the rate of development of the fly, Drosophila acutilabelle, Stalker (1953), at three temperatures, 22°, 25°, and 28°C. It is part of a larger project testing the hypothesis that stenothermal species (those restricted to a narrow temperature range) are more sensitive than eurythermal species, such a the cosmopolitan D. melanogaster and D. hydei (those able to live over a broad temperature range) to the effects of temperature during development. It has been suggested that eurythermal species have a lower Q10 of development. The species used in this study is considered to be stenothermal because it is limited in distribution to Florida, Cuba, Hispaniola and Jamaica, which are regions of relatively warm temperature with little seasonal change.
