Comprehensive knowledge of biodiversity is a prerequisite for its long-term conservation and sustainable use. Fungi play crucial roles in ecosystems and are among the species-richest organism groups on Earth. However, all aspects of their diversity remain underexplored. In this study, we aimed to fill the gaps in occurrence data and taxonomy as well as in understanding spatial diversity patterns of aphyllophoroid fungi (non-gilled macroscopic Basidiomycota). We digitized and made openly accessible 4,041 records of ...

In Uganda many farmer households have diverse agroforestry systems known as homegardens, which have been adapted over generations to supply a year-round harvest of nutritious foods. The work presented in this dissertation sought to identify the factors that influence the agrobiodiversity of these homegardens and to assess the effects of that agrobiodiversity on the health of the households that keep them. Households (n=102) were identified via stratified, random selection across three distinct regional ecological ...

Die Kooperation zwischen den beiden Phasen der Lehrerbildung an Universität und Studienseminar und die Qualitätsssteigerung der schulpraktischen Ausbildung werden nicht nur im Hessischen Lehrerbildungsgesetz als eine der Möglichkeiten gesehen, die Ausbildungsqualität angehender Lehrer zu verbessern. Um die Bedingungen für die Intensivierung der Kooperation zwischen den beiden Phasen bestimmen zu können werden in einer Expertenbefragung (Studie 1) die Haltung und Erwartung von Vertretern der universitären Lehrerbildung, ...

This thesis concerns with the main aspects of medical trace molecules detection by means of intracavity laser absorption spectroscopy (ICLAS), namely with the equirements for highly sensitive, highly selective, low price, and compact size sensor. A novel two modes semiconductor laser sensor is demonstrated. Its operation principle is based on the competition between these two modes. The sensor sensitivity is improved when the sample is placed inside the two modes laser cavity, and the competition between the two modes ...
