The degradation of natural and semi-natural landscapes has become a matter of global concern. In Germany, semi-natural grasslands belong to the most species-rich habitat types but have suffered heavily from changes in land use. After abandonment, the course of succession at a specific site is often difficult to predict because many processes interact. In order to support decision making when ma...

Butterflies and moths (Lepidoptera) have been suggested for the environmental monitoring of genetically modified (GM) crops due to their suitability as ecological indicators, and because of the possible adverse impact of the cultivation of current transgenic crops. The German Association of Engineers (VDI) has developed guidelines for the standardized monitoring of Lepidoptera describing the us...

Honey bees are important pollinators of commercial blueberries in the southeastern United States, and blueberry producers often use supplemental bees to achieve adequate fruit set. However, honey bees also vector the plant pathogenic fungus Monilinia vacciniicorymbosi which infects open blueberry flowers through the gynoecial pathway causing mummy berry disease. Here, we report the results of a...

This study proposes a method to reduce car body elastic vibrations in bullet trains caused by longitudinal excitation via traction devices and yaw dampers. We devised two vibration reduction devices—"displacement-dependent rubber bushes" "mesh springs" suppress the force. conducted tests using Shinkansen (bullet train) type test vehicle rolling stock testing plant examine running stability supp...
