Description: Das Projekt "Pflanzendiversität und Performance im Zusammenhang mit Klima und Landnutzung: Gemeinschaften, Arten, Populationen, ökologische Genetik" wird vom Umweltbundesamt gefördert und von Universität Bayreuth, Fachgruppe Biologie, Bayreuther Zentrum für Ökologie und Umweltforschung (BayCEER), Lehrstuhl für Pflanzensystematik durchgeführt. This subproject aims at the parallel assessment of plant biodiversity and plant performance (biomass, phenology, fitness) along altitudinal and land use gradients in natural and human-disturbed ecosystems at Mt. Kilimanjaro. We will consider plant diversity at genetic, population, and community levels, and their relationship to plant performance. To estimate the diversity, composition and dynamics of plant communities, we will repeatedly record all plant species present on the 60 common study plots. In addition, we will study plant species turnover by revisiting the sites of 180 existing vegetation records. For all 60 common study plots, we will estimate horizontal and vertical community structure, production and biomass (and relate the outcome to data on climate (SP1) and nutrient (SP3) and water (SP2) levels). In the forest plots dendrochronology will allow correlation of tree growth with climate variables (SP1) across altitude and land use systems. In collaboration with SP5 and the plantanimal interaction components of SPs 6-8 on dispersal, pollination, decomposition, and herbivory we will study several species in more detail. For the eight most abundant species per plot, phenology will be recorded. In addition, reproduction will be measured for four rare and four common species measuring biomass of reproductive organs and seed set. We will also estimate molecular genetic variation for these four species. To analyse species responses to different altitudes/climates and local adaptation within species, we will perform reciprocal-transplant experiments of seed families between altitudinal belts for 16 species of different niche width, four endemic, four rare nonendemic, four common, and four invasive. For one species with large altitudinal range we will explore the consequences of outcrossing between different altitudes. Selection gradient analysis will be used to characterize the relationship between within-species variation in functional traits (in collaboration with SP5) and performance. We will closely collaborate with all other subprojects and with our local counter partners at the National Herbarium of Tanzania in Arusha. Our project will provide important baseline data for all other subprojects. Moreover, our data will allow us to relate genetic, population, and community measures of diversity to altitude, climate and anthropogenic disturbance, to quantify biodiversity-ecosystem functioning relationships in the field, and to estimate resilience and adaptive potential of plants from natural and modified ecosystems to global change.
