- Hydration-dependent photosynthetic production of lichens: what do laboratory studies tell us about field performance?O L Lange
Julius von Sachs Institut für Biowissenschaften der Universität Würzburg, Julius von Sachs Platz 3, D 97082 Wurzburg, Germany
J Exp Bot 52:2033-42. 2001..If so, then the phenomenon must have major ecological importance for lichen productivity. In general, laboratory studies seem to be able to predict extremely well the behaviour of lichens in their natural habitat...
- Lichens show that fungi can acclimate their respiration to seasonal changes in temperatureOtto L Lange
Julius von Sachs Institut für Biowissenschaften der Universität Würzburg, Lehrstuhl für Botanik II, Julius von Sachs Platz 3, 97084 Würzburg, Germany
Oecologia 142:11-9. 2005..This would ameliorate this positive feedback loop present in some climate models and might substantially lower the predicted warming...
- Nocturnal respiration of lichens in their natural habitat is not affected by preceding diurnal net photosynthesisOtto L Lange
Julius von Sachs Institut für Biowissenschaften der Universität Würzburg, Lehrstuhl für Botanik II, Julius von Sachs Platz 3, 97082, Wurzburg, Germany
Oecologia 148:396-404. 2006..The periods of desiccation that often occur between the NP and following DR as well as the wide range of combinations of conditions would certainly contribute to this lack of relationship...
- Phototolerance of lichens, mosses and higher plants in an alpine environment: analysis of photoreactionsU Heber
Julius von Sachs Institut fur Biowissenschaften, Universitat Wurzburg, Germany
Planta 211:770-80. 2000..Protonation-dependent fluorescence quenching by cyclic electron transport, P700 oxidation and, possibly, excitation transfer between the photosystems were effectively combined to produce phototolerance...
- Conservation and dissipation of light energy as complementary processes: homoiohydric and poikilohydric autotrophsUlrich Heber
Julius von Sachs Institute of Biosciences, University of Wurzburg, D 97082 Wurzburg, Germany
J Exp Bot 57:1211-23. 2006..Thermal dissipation of absorbed light energy within a picosecond time domain deactivates excited singlet chlorophyll, thereby preventing triplet accumulation and the consequent photo-oxidative damage by singlet oxygen...
- Photoprotection of reaction centres in photosynthetic organisms: mechanisms of thermal energy dissipation in desiccated thalli of the lichen Lobaria pulmonariaUlrich Heber
Julius von Sachs Institute of Biological Sciences, University of Wurzburg, D 97082 Wurzburg, Germany
New Phytol 185:459-70. 2010..Zeaxanthin formation apparently did not contribute to the enhancement of photoprotection by desiccation in the light. Light-induced absorbance changes indicated the involvement of chlorophyll and carotenoid cation radicals...
- Protection of the photosynthetic apparatus against damage by excessive illumination in homoiohydric leaves and poikilohydric mosses and lichensU Heber
Julius von Sachs Institut, Universitat Wurzburg, D 97082 Wurzburg, Germany
J Exp Bot 52:1999-2006. 2001..Excitation of photosystem II by sunlight is not destructive in these dry organisms, whereas photosystem II activity of dried leaves is rapidly lost under strong illumination...
