  • Extreme Makeover: Photosynthesis Edition

    Plants are far better than humans at turning sunlight into food. But they’re not nearly as good as they could be: Thanks to quirks in the systems that have evolved to capture solar energy and use it to build sugars from carbon dioxide and water, the conversion efficiency of photosynthesis is but a few percent at best. With the need to produce more crops growing even faster than human ...

  • Better photosynthesis for a better world?

    There’s no question that plants are better than most other life forms at converting carbon dioxide and sunlight into the sugars that form the basis of our global food web — and eventually, humans’ entire food supply. But fact of the matter is, with conversion rates hovering around 2 percent for our best crop fields, they’re by no means great. Even a slight increase in the ...

  • Phenotypic and genomic responses to titanium dioxide and cerium oxide nanoparticles in Arabidopsis germinants

    The effects of exposure to nanoparticles of titanium dioxide (nano‐titanium) and cerium oxide (nano‐cerium) on gene expression and growth in Arabidopsis thaliana germinants were studied using microarrays and quantitative real‐time polymerase chain reaction (qPCR), and by evaluating germinant phenotypic plasticity. Exposure to 12 days of either nano‐titania or nano‐ceria altered the regulation ...

  • Photosynthesis, chlorophyll fluorescence characteristics and chlorophyll content of soybean seedlings under combined stress of bisphenol A and cadmium

    Bisphenol A (BPA) is ubiquitous in the environment due to its continual application in plastics and epoxy resin industry. Cadmium (Cd) is a highly toxic heavy metal element mainly used in smelting, electroplating and plastic/dye manufacturing. BPA and Cd pollution exist simultaneously in many agricultural regions. However, little information is available regarding the combined effects of BPA ...

  • Realistic environmental mixtures of micropollutants in surface, drinking and recycled water: Herbicides dominate the mixture toxicity towards algae

    Mixture toxicity studies with herbicides have focused on a few priority components that are most likely to cause environmental impacts and experimental mixtures were often designed as equipotent mixtures; however, real world mixtures are made up of chemicals with different modes of toxic action at arbitrary concentration ratios. The toxicological significance of environmentally realistic ...

  • “Green” scientific investigation helps to inform intelligent Green Roof design

    The Green Roof...a seemingly simple concept that underlies an impressive collection of beneficial functions in our sometimes rapidly changing environment. Often the green roof serves as an essential component in sustainable building practices, providing an astonishing array of benefits that range from mitigating building heating and cooling costs, storm water runoff, noise, and urban heat ...

  • SOYPOD: a model of fruit set in soybean

    The soybean [Glycine max (L.) Merr.] plant matches its reproductive potential to environmental conditions by adjusting the number of fruits and seeds that it produces. This adjustment is an important, but not well understood, part of the yield production process. Developing a model of fruit set will contribute greatly to a better understanding of the determination of fruit number and yield. The ...

  • Yield and water use response of cuphea to irrigation in the Northern Corn belt

    Cuphea (Cuphea viscosissima Jacq. x C. lanceolata W.T. Aiton) may be prone to drought stress, yet little is known about the yield response of this new oilseed crop to irrigation. A field study was conducted in western Minnesota on a Barnes loam soil (fine-loamy, mixed, superactive, frigid Calcic Hapludolls) in 2002 and 2003 to compare yield and water use of irrigated and nonirrigated cuphea. ...

  • Simulating gross primary productivity of humid-temperate pastures

    Although most pasture growth models simulate many above- and belowground components of the plant community, calibration and validation are usually based only on periodic measurements of aboveground forage yield. This research used daily measurements of gross primary productivity (GPP) to validate the photosynthesis subroutine of the Integrated Farm System Model (IFSM). The model was calibrated ...

  • Algae Photo Bioreactors (APB`s)

    ALGAE PHOTO-BIOREACTORS (APB’s) Absorption of CO2 and NOx from industrial exhaust gases and conversion of algal feedstock, as a discipline of ecological engineering. Algae, live in a wide range of aquatic environments and are a natural component of most aquatic ecosystems being found in both fresh, brackish and marine waters. They range in size from large macrophytic kelps to microscopic ...

  • Seasonal Dynamics of Periphyton in a Large Tropical Lake

    Tropical aquatic systems are generally assumed to have little seasonality in productivity patterns. However, this study indicated that there was substantial seasonal variation in epilithic productivity and biomass in tropical Lake Tanganyika, due primarily to seasonal patterns in lake hydrodynamics that influence nutrient availability. Although they support much of the lake’s biological ...
