• The ecological role of silicon in tropical forests: effects on plant nutrient stochiometry, drought resistance and herbivory
  

  Silicon (Si) is the second most abundant element in the Earth´s crust and widely recognized to have a variety of functions in plants. Yet we know little about the ecological role of this abundant element in tropical forests, which are among the most species-rich systems on earth and provide important ecosystem services. In this project, we integrate observational data with experimental approaches in the greenhouse, the laboratory and the field to evaluate the effects of Si on nutrient and water relations, and on herbivore defenses in tropical forests. The study will thus substantially contribute to improving the understanding of tropical forests under current and future conditions.

• AQUAKLIF TP5: Prognose und Analyse des Verhaltens kleiner Einzugsgebiete im Kontext des lokalen Klimawandels
  Die Durchschnittstemperatur der Erde steigt schon seit längerer Zeit, die daraus resultierenden Veränderungen in unseren Ökosystemen verstehen wir erst nach und nach. Es ist belegt, dass sich mit dem Klima auch die Wasserchemie der Bäche verändert. In diesem Teilprojekt werden die seit Jahrzehnten gesammelten Daten des integrierten hydrologischen Monitoring-Programms sowie das Quellenarchiv an der Universität Bayreuth statistisch durchleuchtet: Gibt es eindeutige Trends und Muster in den Zeitreihen, die sich auf lokal-klimatische Veränderungen in den Einzugsgebieten zurückführen lassen? Lassen sich ursächliche Zusammenhänge nachweisen? Und lassen sich daraus - in Abhängigkeit der lokalen Klimaszenarien des LfU Bayerns - Prognosen für die zukünftige Entwicklung wasserchemischer Parameter erstellen? [Details]

• Mitigation of urban climate and ozone risks
  MiSKOR "Minderung Städtischer Klima- und OzonRisiken" "Mitigation of urban climate and ozone risks" Part of the joint project "Climate change and health (Klimawandel und Gesundheit) commissioned by the Bavarian State Office for Health and Food Safety (Bayerischen Landesamts für Gesundheit und Lebensmittelsicherheit). The goal is to attain a better understanding of the relevant causes and processes to acquire applicable aids and new possibilities for improving urban planning. We intend to give suggestions how to reduce the negative consequences to human health caused by climate change in combination with the urban heat island effect and high troposheric ozone pollution in a middle-sized city like Bayreuth and comparable cities in Northern Bavaria.

• The role of nutrients for the variability of drought effects on community composition and productivity across land use gradients in grasslands: a trait-based approach
  

  Land use and precipitation are important drivers for shaping community diversity, and ecosystem function in grasslands worldwide, and are two of the main global change drivers. The main aim of this project is to improve our capability of predicting consequences of global change for grasslands through assessing the combined effects of nutrients and drought at the trait and whole plant performance level and integrating them with drought effects on community composition and productivity across land-use gradients in grasslands.

• Drought and grazing impacts in semi-arid rangelands: Testing a novel trait-based conceptual framework
  

  Drought and land use are among the most important global change drivers, particularly for dryland ecosystems. Species and communities in dry areas are assumed to be resistant to both grazing and drought (Generalized Grazing model). However, the generality of this model has been called into question in semiarid rangelands dominated by winter annuals, which exhibit a substantially different strategy to cope with drought than perennials. To test a novel trait-based framework that can resolve the apparent inconsistencies, we use a steep rainfall gradient in the Eastern Mediterranean as a model system, and explicitly link traits, whole plant performance, long-term community responses, and distribution patterns.

• Variation of plant drought tolerance in grasslands: effects on community assembly and ecosystem resilience
  

  Under conditions of climate change, water availability in temperate grasslands is projected to decrease, and extreme events – including droughts - to increase. A thorough understanding of species responses to drought, of the traits governing drought responses, and how they affect community assembly and ecosystem function is necessary for projections of consequences of climate change for the future. In this study, we comparatively assess whole-plant drought tolerance of 38 grassland species, and identify the key traits for differential drought responses, through directly linking physiological, anatomical and morphological traits that influence species water relations to the species’ drought tolerance.
