Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...
Contemporary Ethiopian is, without question, facing enormous challenges. At the core of these challenges lay a state-building process major constituencies and elite groups were either alienated from, forced to acquiesce to, or coopted into. Unable to derive political legitimacy from democratic participation, successive governments largely relied on coercion and neopatrimonialism,...
Once widespread throughout southern Wisconsin, Quercus savannas are now one of the most endangered communities due to fire suppression and increasing landscape fragmentation. These plant communities are also highly susceptible to invasions by nonnative, exotic species. Understanding the mechanisms of exotic species invasion has been the focus of numerous studies....
Restoration managers may select seed from a variety sources for their restoration projects. If the purchased seed is not of the local ecotype, land managers run the risk of poor establishment in the short-term and outcrossing between local and non-local ecotypes, genetic swamping, and the loss of local genetic diversity...
Underutilized crops have the potential to economically benefit developing countries and to improve global food security. Breadfruit (Artocarpus altilis, Moraceae) is one such crop that can provide essential nutrients and requires relatively low-energy input to maintain compared to major crops. Humans have selected for many cultivars of breadfruit since its...
Acoustic emission (AE) testing was used to identify the source of audible “bangs” generated during opening and closing of a large, double-leaf rolling-lift bascule bridge. The data were analyzed using a combination of well-established AE
techniques, including first hit analysis (FHA), planar location analysis, and linear location analysis. The FHA...
With increasing urbanization and creation of novel habitat types, green roofs can provide usable habitat for many species. To date, most research on green roofs has focused on minimizing the environmental impacts of buildings but little is known about the ecological services they provide. Previous research has shown that although...
This book discusses how cities that have developed through the successive stages of capitalism should transform themselves when adapting to the conditions of the contemporary global age. Since modern times, the capitalist economy has largely defined society, politics, and environment—this has casued the collapse of communities, the crisis of democracy,...
The textbook proceeds with an introduction to theory and concept building, moves to an explanation of causal inference (how do we 'know' whether something is causal?), and then provides a quick introduction to data and hypothesis testing. Following that, each chapter is devoted to a particular research method used within...
This report shows that compensation plans have not met the needs of victims of nuclear disasters for three primary reasons: compensation plans have been devised by unelected officials and without full public knowledge or participation, governments have often capped the liability of the owners of nuclear facilities, which distorts cost-benefit...
