Allelopathic effects of bark phenols on epiphytic lichens
(2005)Natural implications for plant growth are important for our understanding of vegetational zonation. <br /> We evaluated allelopathic constraints of natural bark phenols by comparing field data collected from sites with ... -
Ecological studies of epiphytic bryophytes along altitudinal gradients in Southern Thailand
(2010-04-01)Southern Thailand is one of the richest areas in terms of biodiversity. It is a part of the Indo-Burma and Sundaland biodiversity hot spots. It also included the transition zone between Indo-Chinese and Malesian floristic ... -
Evolution and Diversification of the Hookeriales (Bryopsida) with emphasis on Distichophyllum (Daltoniaceae) and its allied genera
(2010-04-01)Unbiased by human intuition in interpreting morphological criteria and by convergence of morphological traits, recent methods in molecular phylogeny is offering an independent option to guide our postulations on phylogeny. ... -
Exploring non-coding mitochondrial DNA sequences in bryophyte molecular evolution
(2010-04-28)The thesis presented here focussed on the molecular evolution of non-coding mitochondrial DNA in liverworts and mosses.<br /> To address remaining questions in moss phylogeny, three mitochondrial gene regions were investigated ... -
Genetic distances and phylogeography of selected disjunct moss populations in Europe
(2006)Disjunct ranges are a common phenomenon in bryophytes. To test, whether these disjunctions are the result of the former continuous ranges (and therefore relicts) or the result of long-distance dispersal (and therefore ... -
Molecular evolution, phylogenetics and biogeography in southern hemispheric bryophytes with special focus on Chilean taxa
(2005)Researchers have long been fascinated by disjunct distribution patterns of plant and animal species. Especially the disjunctly distributed species occurring in the temperate Chilean and New Zealand rainforests of the ... -
Systematic treatment of Sematophyllaceae (Musci) in Thailand
(2008)<p>The taxonomic treatment of the Sematophyllaceae from Thailand was carried out based on about 2000 specimens. These specimens were on loan from herbaria: University of Aarhus, Denmark (AAU); Royal Forest Herbarium, Bangkok ... -
Untersuchungen zu den Auswirkungen atmosphärischer Stickstoffeinträge auf epiphytische Flechten und Moose im Hinblick auf die Bioindikation
(2004)In unterschiedlich stark belasteten Regionen Nordrhein-Westfalens wurde die Epiphytenflora erfasst. Das Vorkommen und die Häufigkeit einiger Arten sind eng mit der Stickstoffbelastung der Standorte korreliert. Landesweit ... -
Untersuchungen zur Eignung von Moosen als Bioindikatoren atmosphärischer Stickstoffeinträge
(2003)Im Rahmen der vorliegenden Arbeit wurde das Akkumulations- und Reaktionsverhalten von Moosen auf simulierte und natürliche atmosphärische Stickstoffeinträge überprüft. Der Schwerpunkt der in Nordrhein-Westfalen und ...
