The role of vegetation in the phytoremediation and ecological recovery of hazardous waste sites.
(2000)
The growth of plant roots in contaminated soils is of paramount importance to the success of phytoremediation. Field observations, coupled with chemical analysis, indicated that the presence of plant roots growing in the ...
Experimental and modeling studies of canopy radiation and water use efficiencies, soil respiration and net ecosystem carbon exchange.
(2002)
Canopy radiation and water use efficiencies (RUE and WUE), soil respiration and interannual availability in net ecosystem carbon exchange (NEE) are important issues in global climate change study. This thesis summarized ...
Rhizosphere ecology of PCB-degrading bacteria at a contaminated site and implications for bioremediation.
(2003)
Rhizosphere bioremediation is an emerging technology that relies on plant roots to enhance bacterial biodegradation of soil contaminants like polychlorinated biphenyls (PCBs), providing an inexpensive alternative to ...
Biosystematics of North American species of Nuttallanthus (Lamiales).
(2003)
The native North American toadflaxes comprise a morphologically-variable complex of herbaceous plants that have been collectively recognized as a section of Linaria (Linaria section Leptoplectron ) or a distinct genus ...
Systematics of the Mecardonia acuminata (tribe Gratioleae, Plantaginaceae) complex of southeastern USA.
(2007)
Seed surface morphology is known to be of taxonomic significance in some plant taxa, and has been used as diagnostic features of some families, genera and species. The tribe Gratioleae (Plantaginaceae) consists of 16 genera ...
Interactions between ecosystem carbon, nitrogen and water cycles under global change: Results from field and mesocosm experiments.
(2005)
N additions increased NEE by enhancing light interception, RUE, and extending growing seasons. Different N application methods (PF versus GF) caused differential seasonal dynamics of LAI, NEE and RUE due to their different ...
