The Effects Of Elevated Co2 Levels On Broad Bean, Vicia Faba, Growth/Defense Tradeoffs, Harley B. Kitching
The Effects Of Elevated Co2 Levels On Broad Bean, Vicia Faba, Growth/Defense Tradeoffs, Harley B. Kitching
Honors College Theses
Atmospheric changes, associated with global climate change, are increasing at an unprecedented rate. Plants generally display higher rates of growth in response to elevated CO2 levels, but this response varies among species. In addition, very little is known about how plant growth/defense tradeoffs will be altered by increasing CO2 levels. By raising Broad bean, Vicia faba L., plants under ambient (400 ppm) and elevated (900 ppm) levels of CO2, it was shown that atmospheric composition directly altered plant growth/defense tradeoffs. Plants grown under elevated CO2 had lighter stem weights but greater numbers of extrafloral nectaries …

Temporal Patterns Of Aquatic Macroinvertebrate Communities And Organic Matter Standing Stock Availability In A Coastal Floodplain (Altamaha River, Georgia), Erica L. Johnson
Electronic Theses and Dissertations
River floodplain habitats of the Southeastern United States are sites of high biological productivity that rely on a predictable flooding event as a keystone process. This study took place in a river-floodplain area of the Altamaha River, an unimpounded large-order river in the Coastal Plains region of the US. This study aims to investigate how aquatic macroinvertebrate communities changed over the course of the annual flood pulse. I predicted that the communities would be different and that the differences would be driven by hydrology at the main stem and organic matter standing stock availability. I took quantitative samples of benthic …
