Wolves in sheeps' clothing: Creationist manipulation of Kansas science standards

So the question that animates this paper is this: what happens when a state's education policy seeks to make popular social and religious values a central part of its education standards in direct confrontation with the Establishment Clause of the First Amendment of the U.S. Constitution? I will try to answer that question in three ways. First, I will examine the tactics used in the manipulation of curricula to reflect social and religious values, with special focus on the Kansas case. Second, I will try to ascertain the determinants of success in these efforts; under what conditions are movements to impose creation science on public school curricula likely to succeed, and when to fail? Third, I will try to place these struggles over educational curricula, and between religion and science, in broader context, focusing on what they tell us about the nature of public policy making in the contemporary United States.

The Pollination Biology and Mating System of a Peripheral Population of Witheringia solanacea (Solanaceae)

Pollinator visitation rates over the life of a flower are determined by pollinator abundance and floral longevity. If flowers are not visited frequently enough, pollen limitation may occur, favoring the evolution of self-compatibility (SC). In plant species with varying SC levels, central populations often are self-incompatible (SI) and peripheral populations are SC. Witheringia solanacea (Solanaceae) is a species that follows this trend with the exception of one population in the Monteverde Cloud Forest Reserve, which is peripheral yet SI. I investigated this population using multiple techniques including floral bagging, pollinator observations, microsatellite analysis, and floral longevity manipulations. My results confirmed the self-incompatibility of the Monteverde population and indicated low but perhaps adequate rates of pollinator visitation per flower per hour. I found reduced genetic diversity at Monteverde and gene flow occurring unidirectionally from San Luis (a central population) to Monteverde. In the greenhouse, there was more of an effect of male than female function on floral longevity, but the largest differences were environmental. Flowers stayed open substantially longer when cool, cloudy weather was simulated and shorter when conditions were hot and sunny. The results indicate that the Monteverde population of W. solanacea is SI because 1) it is unable to maximize its fitness due to gene flow from San Luis and its relatively recent colonization of the area and 2) pollen limitation may not be severe because of supplemental pollinator availability from other Witheringia species in the area and increased floral longevities due to cool and cloudy conditions.
