Vegetation and fire history in Araucaria forest and Grasslands, Southern Brazil
(2021-06-18)Southern Brazil offers a great opportunity to analyse woodland and grassland mosaics, their pollen-vegetation relationships and its long-term vegetation and fire history. This research was carried out in two stages; first ... -
Vegetation and functional diversity of sand dune habitats between and within different bioclimatic regions
(2017-08-08)Use of plant functional types has a long tradition in ecology from the time that von Humboldt offered the first physiognomic classification of plants based on growth form. In recent years, the application of functional ... -

(2004-03-03)Pollen analytical and archaeobotanical investigations towards the reconstruction of landscape development and settlement history in Northeast Lower Saxony were combined and complete ... -
Vegetationsgeschichtliche Untersuchungen in der westlichen Prignitz, dem östlichen Hannoverschen Wendland und der nördlichen Altmark
(2008-10-21)Cores from the Arendsee, the Rambower Moor and a small bog at the Laascher Heuweg have been palynologically investigated. This enabled the reconstruction of vegetation history and ... -
Ventilatorische Rhythmogenese im isolierten Insektennervensystem
(2001-06-20)Ventilation and underlying neural rhythmogenesis were investigated on the behavioural, neuroanatomical and neurophysiological level in different locust species (Locusta migratoria, Schistocerca ... -
Veranschaulichung subzellulärer physikalischer Kräfte biochemischen und mechanischen Ursprungs mittels FRET
(2005-12-09)The cellular cytoskeleton is composed of microfilaments, intermediate filaments, microtubules and a host of accessory proteins that control its dynamics during different, cell-type and ... -
Verbesserung kognitiver Leistungen bei chronischer Schizophrenie durch rekombinantes humanes Erythropoietin (rhEPO)
(2008-07-15)Schizophrenia is increasingly recognized as a neurodevelopmental disease with an additional degenerative component, comprising cognitive decline and loss of cortical gray matter. ... -
Vergleich der Genexpression im entzündlichen Kolonepithel und im kolorektalen Karzinom im Hinblick auf das erhöhte Tumorrisiko bei chronisch entzündlichen Darmerkrankungen
(2008-02-04)In this thesis, the alterations are investigated that are responsible for an increased tumour risk in colonic epithelium of humans with inflammatory bowel disease (IBD). To detect early ... -
Vergleich der Radikalreaktionen von Melatonin und strukturverwandten Indolaminen in unterschiedlichen Oxidationssystemen.
(2007-01-29)A comparison analysis in structure related Indolamine of Melatonin showed that small changes of Substituenten already draw considerable losses after themselves in oxidation chemistry. ... -
Vergleichende biochemische und strukturelle Untersuchung thermophiler α-Amylasen
(2006-02-14)A number of microorganisms exist in extreme environments. For example hot habitats are colonized by thermophilic archea and bacteria. Due to their physicochemical characteristics enzymes ... -
Vergleichende Evaluationsstudie zur Wirksamkeit des Tinnitus-Bewältigungs-Trainings und der Tinnitus-Retraining-Therapie
(2003-07-25)Using a randomized control group design the long term efficacy of Tinnitus-Retraining-Therapy (TRT) as conceived by Jastreboff (1996a) was compared to the Tinnitus-Coping-Training (TCT, ... -
Vergleichende Untersuchungen zum teratogenen Potential von Detergentien und Retinol für die Entstehung von Wirbelsäulendefekten während der Embryogenese und Larvalentwicklung von Brachydanio rerio (Ham.Buch.) und Xenopus laevis (Daudin)
(2007-03-12)Valuation of the toxicity of detergents and other substances on aquatic systems requires a set of tests on differen aquatic organisms. Because of their lower sensitivity, tests on adult fish have gradually been ... -
Verhalten und Raumnutzung von Exmoorponys im Reiherbachtal (Solling)
(2015-07-16)From autumn 2011 to autumn 2013 the behaviour and the habitat use of Exmoor ponies under semi-natural conditions were studied in the area of Solling-Vogler. Ten focus animals lived in a 140 ha wide area and were observed ... -
Versuche zur Strukturaufklärung bakterieller Thiouridin Synthetasen
(2006-06-02)The tRNA of most organisms is postranscriptionally modified. The sulfurtransferases ThiI and MnmA modify tRNAs by the incorporation of sulfur. In archaea and bacteria two different roles ... -
Verticillium dahliae transcription factors Som1 and Vta3 control microsclerotia formation and sequential steps of plant root penetration and colonisation to induce disease
(2018-10-12)Verticillium dahliae belongs to the soil-borne ascomycete fungi. It causes wilt diseases and early senescence in more than 200 plant species including economically important crops. It can exist in the soil without a host ... -
