Cattail or Typha, an emergent aquatic macrophyte widely distributed in lakes and other shallow water areas, has slender blades with a chiral morphology. The wind-resilient Typha blades can produce distinct hydraulic resistance for ecosystem functions. However, their stem may rupture and dislodge in excessive wind drag. In this paper, we combine fluid dynamics simulations and experimental measur...

The herbicidal properties of sulfonylureas (SU's) were first reported in 1966 (Koog, 1966). The early SU's were derivatives of triazine herbicides. George Levitt of DuPont noted that SU's having aniline as the aryl group exhibited weak plant-growth regulatory activity while the aminopyrimidine derivative displayed very high biological activity (Levitt, 1983; Sauers and Levitt, 1984). Soon compa...

[1] Exchange of carbon between forests and the atmosphere is a vital component of the global carbon cycle. Satellite laser altimetry has a unique capability for estimating forest canopy height, which has a direct and increasingly well understood relationship to aboveground carbon storage. While the Geoscience Laser Altimeter System (GLAS) onboard the Ice, Cloud and land Elevation Satellite (ICE...
