- research articleActa agriculturae Scandinavica. Section B, Soil and plant scienceThis paper presents water erosion data of three stationary series of field experiments (each analysing 10 land plots) on various steepness slopes with different soil texture of the hilly topography of Western Lithuania (Zemaiciai Upland). Six different erosion-preventive crop rotations (four field crop rotations and two perennial grasses for sward formation) were investigated. It was demonstrated that extent of water erosion depends on erosion-preventative capabilities of different crop rotations, slope gradient, soil texture and the amount of precipitations. According to the results of long-term experiments, the mean annual erosion rate under the grass–grain rotation decreased by 95.0% compared with crop rotation with black fallow. The annual soil loss (SL) due to water erosion in the crop rotation with bare fallow was estimated to be between 0.01 and 18.56 t ha−1 yr−1. Usage of long-term grass sward completely prevented soil erosion. Perennial grasses and grass−grain crop rotations also prevented soil erosion on slopes during rainstorm (41–65 mm of precipitation during the day). However, even grain–grass rotations could not completely prevent the water erosion on the 9°–11° slopes with light textured soils. SL rate in 5-year rotation was 1.64 and 1.41 t ha−1 yr−1, respectively. Soil water erosion and nutrient losses are effectively inhibited by long-lived perennial grasses. Covering slopes with erosion-preventive sward forming perennial grasses in many cases prevented available potassium (K) and phosphorus (P) loss from inside the soil, however, the K and P losses resulting from runoff were 0.005–1.0 and 0.001–0.071 kg ha−1, respectively.

Treatment with angiotensin-converting-enzyme (ACE) inhibitors reduces the rate of cardiovascular events among patients with left-ventricular dysfunction and those at high risk of such events. We assessed whether the ACE inhibitor perindopril reduced cardiovascular risk in a low-risk population with stable coronary heart disease and no apparent heart failure. Methods We recruited patients from October, 1997, to June, 2000. 13 655 patients were registered with previous myocardial infarction (64%), angiographic evidence of coronary artery disease (61%), coronary revascularisation (55%), or a positive stress test only (5%). After a run-in period of 4 weeks, in which all patients received perindopril, 12 218 patients were randomly assigned perindopril 8 mg once daily (n=6110), or matching placebo (n=6108). The mean follow-up was 4.2 years, and the primary endpoint was cardiovascular death, myocardial infarction, or cardiac arrest. Analysis was by intention to treat...

Hoboken : Wiley, 2010, vol. 8, iss. 3., p. 135-144Recent comprehensive data provided through the DAISIE project (www.europe-aliens.org) have facilitated the development of the first pan-European assessment of the impacts of alien plants, vertebrates, and invertebrates – in terrestrial, freshwater, and marine environments – on ecosystem services. There are 1094 species with documented ecological impacts and 1347 with economic impacts. The two taxonomic groups with the most species causing impacts are terrestrial invertebrates and terrestrial plants. The North Sea is the maritime region that suffers the most impacts. Across taxa and regions, ecological and economic impacts are highly correlated. Terrestrial invertebrates create greater economic impacts than ecological impacts, while the reverse is true for terrestrial plants. Alien species from all taxonomic groups affect “supporting”, “provisioning”, “regulating”, and “cultural” services and interfere with human well-being. Terrestrial vertebrates are responsible for the greatest range of impacts, and these are widely distributed across Europe. Here, we present a review of the financial costs, as the first step toward calculating an estimate of the economic consequences of alien species in Europe.
