Factors Affecting The Growth Of Didymosphenia Geminata In New Zealand Rivers: Flow, Bed Disturbance, Nutrients, Light, And Seasonal Dynamics.

Cullis , James D 1 1 Civil Environmental and Architectural Engineering (CEAE) and Institute for Arctic and Alpine Research (INSTAAR) Didymosphenia geminata (didymo) was introduced into a New Zealand river in 2004, and since then has dramatically spread to cover the beds of many rivers with extremely dense and extensive...

Soybeans Grown In Elevated Ozone Show Decreased Evapotranspiration That Could Have Implications On Midwest Climate And Hydrology

Casetllani , Benjamin B 1 1 Univeristy of Colorado at Boulder As a result of increasing anthropogenic emissions of pollutants, tropospheric ozone levels are projected to rise 40 to 60 percent by the year 2100 (IPCC 2007). This study focuses on the effect that this increase would have on the...
