Sapling growth and recruitment as affected by flooding and canopy gap formation in a river floodplain forest in southeast Texas
I used sapling population data collected since 1980 to investigate how canopy disturbance interacts with chronic understory disturbance to determine regeneration patterns. I reconstructed flooding history using a combination ...
Characterization of the acetone production pathway genes from Clostridium acetobutylicum ATCC 824
In Clostridium acetobutylicum the three enzymes thiolase, CoA-transferase, and acetoacetate decarboxylase serve to catalyze the formation of acetone from acetyl-CoA. This process is unique to butyric-acid clostridia and ...
Methane emission from irrigated rice cultivation: Quantities, models and practice
Three experiments focused on the contribution of rice productivity to methane emission were conducted in Texas flooded rice paddy soils during 1994-95 growing seasons. Measurements of methane emission from different rice ...
A study of the fluid mechanics and the cultivation of mammalian cells in a magnetically stabilized fluidized bed bioreactor
The culture of anchorage dependent mammalian cells on microcarrier offers an attractive avenue for achieving high productivity of therapeutic and diagnostic proteins in bioreactors. Reducing production costs require high ...
Effects of fire on vegetation in the Big Thicket of southeastern Texas, United States of America
This study shows that fire had a strong short-term effect on the small-sized individuals in the understory of two dry upland vegetation types, sandhill and upland pine. Large trees were less affected than saplings and small ...
Intervarietal differences of methane emission related to plant parameters in irrigated rice cultivation
Field and laboratory experiments were conducted with the following ten cultivars of rice: Lebonnet, Lemont, Dawn, Katy, Della, IR36, Mars, Brazos, Labelle and Jasmine. For each variety, components of biomass, root porosity ...
