The brown trout Salmo trutta stock in a small near-natural tributary of the river Danube was monitored during six consecutive years. To protect the local fish community against existing predation by cormorants, after the first year of the study riparian trees were cut down and placed into the river. However, this structural intake had no positive effect for the brown trout stock. An increase of the density was only measured after stocking hatchery-reared young brown trout. But this increase holds only for a short time, after one winter the former small trout abundance was measured again. The main reason for this low density seems to be the high prédation rate by cormorants during wintertime. Therefore, the intake of wooden debris, even if it is supported by stocking, seems not suitable to guard fish stocks sustainable against prédation by cormorants.

Pfrunger-Burgweiler Ried (2600 ha) is the second largest peatland in south western Germany. In autumn 2010, the first section of the Obere Schnöden fen (235 ha) was rewetted as part of a large scale conservation project of national importance. The project aims to regenerate a growing percolation mire in the centre, with low intensity grazing at the margins. Rewetting included the following construction activities: • Destruction of underground drainage and closing of open ditches to reactivate former spring mires, • Banking-up, deflecting and subsequent surface percolation of incoming spring streams, • Banking-up, deflecting and subsequent surface realignment of the main water course crossing the area to create an initial mire stream • Segmentation and shallow damming-up of all drainage ditches and significantly deepened residual water courses including their slump hollows. For the first time in Germany, very durable blocking dams were made using sheet piling made of recycling plastic. Due to the relatively high involvement of machinery, and the significant large-scale effects seen immediately after accomplishing the work, the project gave rise to some local conflicts despite the comprehensive accompanying public relations activity.

Mineral nitrogen (N) fertilization in cereals is commonly split into three or four applications. In order to simplify N fertilization, a single N application either broadcast or placed on the soil surface was compared to conventionally split fertilization for winter wheat (Triticum aestivum L.). The 4-year experiment (2007-2010) was performed using a participatory approach on farmers' fields on deep loamy soils (Luvisols) in South-West Germany. Grain yield and crude protein contents differed only slightly or not at all between treatments including different N fertilizer types (calcium ammonium nitrate, urea ammonium nitrate solution, urea) and application techniques (broadcast, placed). Furthermore, no differences were found for the yield components ears/m2 and thousand grain weight. Inorganic N in the soil profile after harvest was generally below 40 kg N/ha and did not differ between treatments. In the area where N was placed, mineral N was depleted during the vegetation period. At the experimental sites a single N application in the period between tillering and stem elongation was sufficient to achieve high yield and quality of winter wheat without increased risk of nitrate leaching. This finding was independent of the method of application or the type of fertilizer. © 2014 Cambridge University Press.

We studied the aquatic vegetation of bottom-rooted plants, i.e. the class Potametea, in Baikal Siberia, a region in the south of Eastern Siberia. Forty associations were found based on 623 original relevés and 65 relevés from the literature. Six associations (Lemno trisulcae-Sparganietum graminei, Myriophyllo spicati-Potametum compressi, Potametum bottnici, Potametum maackiani, Potametum salicifolii, Potametum vaginati) are described here for the first time. The names of five syntaxa have been typified. Nine new community-types were recorded for Baikal Siberia. Each association is outlined by its diagnostic, constant and dominant species, structure, ecology and distribution. The regional distribution of each association is shown by grid maps. Large-scale phytogeographical comparison of sets of diagnostic species of Potametea across Northern Eurasia revealed that Baikal Siberia harbours two thirds of the diversity of macrophyte vegetation of Northern Asia and 40% of that of Northern Eurasia. Our study showed that Baikal Siberia's Euro-Siberian aquatic vegetation gradually declines in species and community richness towards east. The aquatic vegetation was found to be rich in thermophilous plants in the Russian Far East along the lower course of the Amur River. © 2013 Gebrüder Borntraeger, 70176 Stuttgart, Germany.

The directive of the German Medical Association for quality of medical laboratory examinations shows the requirements of procedures and instructions for examinations. The implementation of these requirements in a laboratory guarantees reliable results in this field of medicine and a reliable detection of disease and targeted treatment of patients. In this article, the development and requirements of the directive are presented. The results of the supervising authorities investigating the implementation and application of the requirements of the directive through the medical laboratories in the past 3 years show many shortcomings, particularly in the sector of doctors' surgeries of general practitioners and medical specialists.

Red yeast rice (i.e., rice fermented with Monascus spp.) is currently sold via the Internet as a dietary supplement. Claims state that red yeast rice has the ability to lower blood cholesterol concentrations. The mechanism of action is well characterised because the red yeast rice constituent monacolin K is identical with lovastatin, an inhibitor of the hydroxymethylglutaryl-CoA (HMG-CoA) reductase that is used in many cholesterol-lowering medicinal products. The aim of this article is to evaluate the properties of red yeast rice products that are marketed via the Internet. Three out of five analyzed products may reach the daily dosage of 10 mg lovastatin, which is necessary for the substantiation of health claims on the maintenance of normal blood LDL-cholesterol levels as suggested by the Scientific Opinion of the European Food Safety Authority. 10 mg is also the starting dosage of medicinal lovastatin products on the (Berman market. From a regulatory standpoint, red yeast rice products would rather have to be sold as medicinal products than as food supplements as they clearly exhibit a pharmacological action that is comparable to approved statin-containing medicinal products. This also implies potential adverse effects and interactions, about which the consumer is insufficiently informed in the case of food supplements. The lack of control over the Internet market is evidenced by the fact that four of the tested products were not marketable in conventional trade in Germany due to violations of labelling rules.
