Ecologically derived immission values for phosphorus in rivers - The Rott case study
No full textS.271-285 : Abb.,Tab.,Lit.Flow regulations of rivers result in elevated retention times and in subsequent eutrophication effects, such as algal mass development. These phenomena were studied in a small river and its shallow flood retention basin (River Rott, Lower Bavaria) from 1982 to 1988. Algal mass developments (median value at the outlet: 125, 90 percentile > 300 myg/l Chlorophyll = Chl) significantly exceed those in the Rivers Ruhr and Main in both in concentration and duration. The latter rivers are similar in nutrient contents. The main reasons for this deviation in the River Rott system are thought to be the shallowness of the flood retention basin and the high content of riverine solids in the water. We assume that the latter fact favours diatom dominance throughout the whole year. The Phosphorus limits which control eutrophication effects for the Rivers Ruhr and Main are far too high for the River Rott and will not reduce algal mass development in this system

Sugarcane Mosaic
No full textMosaic’s most distinctive symptom is a pattern of contrasting shades of green, often islands of normal green on a background of paler green or yellowish chlorotic areas on the leaf blade. It had not been a problem in Florida until 1996, when it was observed on CP72-2086, a major commercial cultivar, near the intersection of Hatton Highway and US 98. Presently, because of the limited acreage of CP72-2086, the disease is only a potential threat. This revised 3-page fact sheet was written by P. Rott, J. C. Comstock, R. A. Gilbert, and H. S. Sandhu, and published by the UF Department of Agronomy, March 2015. (Photo: Philippe Rott, UF/IFAS)
