The prairie grasses Andropogon gerardii and Sorghastrum nutans have seeds with awns that twist in response to changes in humidity. The humidity-sensitive, or hygroscopic, part of the awn twists, moving the bent, passive portion in an arc. This trait has been demonstrated to improve seedling recruitment in other grass species...

"Abstract
Purpose: Research establishes the critical need to address the underrepresentation of women and racial/ethnic minorities in science, technology, engineering, and mathematics (STEM). While emergent research addresses similar challenges for sexual and gender minorities (SGM), this research remains scant and focuses on adult experiences. This analysis examines subgroup differences and... and ARCH Deposit Description:

Understanding how contexts shape child development is a primary goal of human development research and theory. Child effects, or the influence of children on their own environment, may be a key process by which contexts and children interact to shape subsequent development. Yet, child effects have been under-studied in social...
This dissertation project explores the relationship between the architectures of black masculinity in America and a specific performance of discreet sexual identity. Through critical ethnographic and discursive exploration, I look closely at a group of black men who describe themselves as being on the "down low" (DL). These men, who...
The tallgrass prairie once dominated much of the mid-western United States. Today, this highly productive system has been severely reduced, contributing to an array of environmental problems. The recent renaissance in natural area restoration and stewardship of the tallgrass prairie in the Chicago Wilderness region (Illinois, USA), especially in the...
Habitat fragmentation can alter the conditions of natural plant populations, introducing novel selective pressures. The ability of a population to respond to environmental change can be inferred by assessing the population’s genetic diversity and the heritability of traits thought to be under selection.
Plant-aphid systems provide a valuable opportunity for studying the ecological consequences of land use change for interacting species. The North American tallgrass prairie has undergone severe reduction and fragmentation due to agricultural development. The prairie perennial Echinacea angustifolia, a model system for studying population-level effects of habitat fragmentation, hosts a...
