Systematic studies in the Poaceae and Cyperaceae /
(The University of Oklahoma., 1985)
Descriptions of the following genera were prepared for the volume treating the Poaceae for the Vascular Flora of the Southeastern United States: Ammophila, Arrhenatherum, Brachyelytrum, Briza, Cynosurus, Dactyloctenium, ...
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 ...
Studies in the Cactaceae.
(1980)
Five taxa representing the three tribes of the Cactaceae have similar patterns of stamen and carpel initiation but display differences in early receptacle development. The first ring of stamens and the carpels arise ...
Molecular systematics of Artemisia section Tridentatae (Asteraceae).
(1997)
Chloroplast DNA restriction site variation was used to examine phylogenetic relationships in Artemisia sect. Tridentatae, a complex of eleven species of woody shrubs dominant in the sagebrush communities of western North ...
Biosystematic studies in the Echinocereus viridiflorus complex.
(1980)
Pollen of the Echinocereus viridiflorus complex is uniform throughout the group. The pollen is isopolar, radially symmetrical, prolate spheroidal, tricolpate, and 44 - 52 (mu) in diameter with a puncti-baculate exine. ...
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 ...
Plant competition theory: Empirical tests from the tallgrass prairie.
(1997)
Depending upon the parameter and scale of measurement, evidence for each model exists. Further studies of "natural" resource and disturbance regimes (e.g, fire, urine patches, grazing) with greater temporal complexity are ...
Studies in the Danthonieae (Poaceae) /
(1984)
Finally, treatments of the genera and species of Arundo, Phragmites, and Danthonia in the southeastern United States are presented.
Systematic studies in Physalis (Solanaceae) /
(1984)
(4) Physalis (for the Vascular Flora of the Southeastern United States). Measurements were made from over 6,500 herbarium sheets and personal collections, and updated keys and descriptions were written for the 20 species ...
