• W2320614163 abstract "This is a study of the demographic and genetic consequences of long term exposure to a novel husbandry regime in laboratory populations of two strains of the flour beetle Tribolium castaneum. An alteration of the husbandry represents an environmental change, and a resulting shift in the demographic characteristics of populations exposed to this new environment for long periods of time could be attributed to an evolutionary response if the shift can be shown to be genetic. Certainly the demographic traits of populations have a genetic basis and are subject to natural selection. The effect of selection on demography has not been studied extensively though there have been some theoretical and empirical considerations. Some of these conclude that the intrinsic rate of natural increase r should be maximized either by an increase in fecundity or a decrease in developmental time (Dobzhansky, 1968; Stern, 1970). Other authors believe selection should maximize population size or biomass (Carson, 1957, 1961; Fisher, 1958; and Ayala, 1966). The empirical results presented here are contrary to these predictions and indicate some of the problems associated with making predictions at the population level based on the outcome of selection on individuals. This work has its antecedents in studies documented by Sokal and Sonleitner (1968) and Sokal and Fujii (1973). To follow changes in the frequency of the mutant allele black (b) subsequent to its introduction to wild type populations of the normally long-lived beetles, the above authors designed a scheme in which discrete generations were imposed on the experimental populations. Since laboratory stocks are maintained under conditions permitting overlapping generations, this novel regime radically altered the ecology of the experimental cultures. Competition among like life history stages was intensified and the reproductive period shortened by the process which will be described fully below. In their experiments, Sokal and his coworkers established many replicate populations with discrete generations for the pure wild type and pure bb (the Chicago Black strain marked by bb) as controls to their selection experiments. Experimental populations of both strains followed characteristic patterns of rapid increase in adult population size followed by a leveling off period. The pure bb populations then underwent a severe long term decline in adult numbers while the wild type populations declined only slightly, maintaining levels near their earlier peak. The time period involved is in excess of 40 generations. It is postulated that the altered population sizes have a genetic basis and are a result of adaptation to the novel environment. Differential responses in the Chicago Black and wild type strains result from genetic differences inherent in the two strains. 1 Current address: Department of Biology, University of Chicago, 1103 East 57th Street, Chicago, Illinois 60637. 2 Contribution Number 193 from the Program in Ecology and Evolution, State University of New York at Stony Brook." @default.
