Abstract

Abstract: The consequences of different management strategies following natural disturbances are a matter of global concern. In former production forests around the Northern Hemisphere, the abandonment of intervention, such as removal of dead wood, after outbreaks of bark beetles has been increasingly promoted to regain more natural conditions. However, many focal species of conservation, such as the barbastelle bat Barbastella barbastellus, do not primarily depend on dead wood but might respond indirectly to disturbance‐induced changes of forest structural attributes. We investigated the response of B. barbastellus foraging activity and roost selection by combining acoustic surveys, radio telemetry, and airborne light detection and ranging (LiDAR) to characterize B. barbastellus habitat use on different scales. B. barbastellus foraging activity increased with increasing canopy opening. Maternity colonies were recorded exclusively in trees killed by bark beetles. Bats preferred roost trees with a higher volume (m3 ha−1) of live trees in the surrounding, and trees with on average larger diameters than nearby control trees. Our results revealed that outbreaks of bark beetles result in forest structural attributes that are suitable habitat for B. barbastellus. Salvage logging, i.e., the removal of beetle‐affected trees, generally deteriorates the positive effects of bark‐beetle outbreaks on the foraging and roosting habitat of B. barbastellus. We recommend maintaining snags of large diameter if salvage logging is mandatory. [ABSTRACT FROM AUTHOR]

Abstract

Hintergrund: Zur Minimierung von Schmerz und Nebenwirkungen wird sanfte retinale Photokoagulation z. B. durch kürzere Bestrahlungszeiten oder Mikropulslaser versucht. Diesen Techniken ist gemein, dass für die Dosierung ophthalmoskopisch unsichtbarer Läsionen keine praktikable Effektkontrolle[for full text, please go to the a.m. URL], 25.

Abstract

We report results on the performance of a free electron laser operating at a wavelength of 13.7 nm where unprecedented peak and average powers for a coherent EUV radiation source have been measured. In the saturation regime the peak energy approached 170 μJ for individual pulses while the average energy per pulse reached 70 μJ. The pulse duration was in the region of 10 femtoseconds and peak powers of 10 GW were achieved. At a pulse repetition frequency of 700 pulses per second, the average EUV power reached 20 mW. The output beam also contained a significant contribution from odd harmonics of approximately 0.6% and 0.03% for the 3rd (4.6 nm) and the 5th (2.75 nm) harmonics, respectively. At 2.75 nanometers the 5th harmonic of the radiation reaches deep into the water window – a wavelength range that is crucially important for the investigation of biological samples.

Abstract

This report contains a comprehensive technical description of a new international research infrastructure, the European X-Ray Free-Electron Laser (XFEL) Facility. It was written between October 2005 and June 2006 and provides a realistic cost estimate and a compelling assessment of the scientific pay-off. The report has been prepared with the contribution of hundreds of people from many laboratories in Europe and even beyond. Their contributions have been harmonised and merged by many editors, and the whole effort has been coordinated by the European Project Team, generously supported and hosted by the Deutsches Elektronen-Synchrotron (DESY) laboratory.
