Habitat ecology and long-term development of the macrophyte vegetation of north-west German streams and rivers since the 1950s
(2013-11-08)This PhD thesis deals with the habitat characterization and the long-term development over 60 years of the macrophyte vegetation of north-west German running waters in order to contribute to the knowledge about the ecology ... -
Habitat selection, cryptic diversity, phylogeny, and phylogeography of the European Lepidocyrtus lanuginosus species group (Collembola: Entomobryidae)
(2019-02-12)Accurate species identification and assessment of species diversity are essential for studies on phylogeny and phylogeography, adaptation and ecological function. The development of molecular methods triggered the discovery ... -
Habitat Suitability Modeling for Tiger (Panthera tigris) in the Hukaung Valley Tiger Reserve, Northern Myanmar
(2012-10-11)This study based on the aim to contribute to the effective conservation of suitable tiger habitat by drawing habitat suitability map. We modeled habitat suitability using the empirical multivariate approach of the ... -
Habitat use and population viability of the Red Kite (Milvus milvus) in Germany
(2021-05-04)The Red Kite (Milvus milvus) is a European near-endemic raptor species and due to its limited distribution and small global population size in the focus of national and international conservation efforts. Even within Europe, ... -
Halmbasis- und Wurzelkrankheitserreger an Weizen (Trititcum aestivum L.) in Energiefruchtfolgen und Bedeutung des Halmbasisbefalls mit Fusarium culmorum (W. G. Smith) Sacc. und Fusarium graminearum (Schwabe) für die Mykotoxin-Kontamination der Pflanze
(2013-04-16)In the present study, the impact of energy crop rotations on stem basis and root pathogens of winter wheat (Triticum aestivum L.) was evaluated by means of a two-way factorial design in field trials conducted at two locations ... -

(2014-07-07)The South American Gran Chaco with its particular geological and climatic conditions is especially susceptible to salinization of soils and water. The aim of this study was to analyze the phytogeography and the phytosociology ... -
Handbuch der monogenen Erbmerkmale beim Hund
(2008-10-01)The objective of the present thesis was to compile all monogenic hereditary diseases and traits whose molecular genetic causes have been identified to date (status quo in October 2007). ... -
HappyFace as a monitoring tool for the ATLAS experiment
(2016-10-24)The importance of monitoring on HEP grid computing systems is growing due to a significant increase in their complexity. Computer scientists and administrators have been studying and building effective ways to gather ... -
Hard X-ray Waveguide Optics
(2005-11-18)The thesis is about the preparation of intense hard X-ray nanobeams focusing on the use of X-ray waveguides in resonant beam coupling and front coupling geometry. -
Harmonic analysis on 2-step stratified Lie groups without the Moore-Wolf condition
(2022-04-07)In this thesis we investigate harmonic analysis on a particular class of sub-Riemannian manifold, namely the 2-step stratified Lie groups $\mathbb{G}$, as well as its applications in partial differential equations. This ... -
