Biological Sciences Theses & Dissertations
The levels of atmospheric CO2 are rising and this affects the growth of plants and the ecosystems in which they reside. Plants take up additional C from the atmosphere and have potential to sequester C in the soil. I investigated the sequestration of C belowground and the microbial processes that control C retention in the soil. This study was conducted in a Florida scrub-oak ecosystem, where CO2 levels have been elevated to twice ambient since 1996 in open top chambers. There were eight replicates of ambient CO2 chambers and eight replicates of twice-ambient CO2 levels. The …
