Climate change is accelerating, and is increasingly affecting species and ecosystems. One of the key questions we face is, how severely these effects will alter the geographic distribution of species, and the component communities, and how this will affect the heritage of whole biota, with their evolutionary relationships and functional trait variability. Nature conservation efforts have long attempted to protect (as many as possible of) threatened species. With rapidly increasing threats from climate and global change to large biota, we will have to expand our thinking and planning to ascertain that we conserve the evolutionary heritage, not simply species. This suggests that we do not necessarily only consider “rarity” of species, with similarly rare species being equally important for conservation. Instead, we shall also consider, how much independent evolutionary heritage and trait variation they contain. This is a rapidly growing field of research in ecology, but to date, no general conclusions can yet be drawn. We still lack detailed knowledge on how phylogenetic (representing evolutionary relatedness among species) and functional (representing trait variation among species) variability are structured along environmental, elevational or spatial gradients, how functional and phylogenetic patterns compare to species (taxonomic) diversity patterns, and how the relationships among these three levels of diversity can be integrated into a more compound planning for nature conservation.With this project we aim at analyzing (1) how species-specific, functional and phylogenetic patterns in plants are structured along environmental (climate, elevation) and spatial gradients, (2) how plant community structure changes along elevation gradients and how the spatial scale of analysis affects the found patterns, (3) how (species, phylogenetic and functional) diversity patterns are likely to respond to climate change, and (4) what the consequences are for nature conservation. We will analyze these questions by means of grassland vegetation data in Switzerland. Answering these questions will allow us to (i) single out important drivers of the evolution of floristic diversity, (ii) analyze the structuring of this diversity into communities in the European Alps, (iii) to evaluate, how climate change may affect these different diversity patterns in the future, and (iv) to explore pathways how this information can be used to extend conservation planning of grasslands in Switzerland. The proposed research, although ambitious, is feasible due to the excellent data basis readily available, which requires only minimal updating. Specifically, we have (a) a general, species-level phylogeny available encompassing all plants inhabiting the European Alps (according to Aeschimann’s Flora Alpina), (b) a large database of community level, and species distribution data from several national and project-specific databases, (c) a detailed, high-resolution (100m) database of climate and environmental predictor maps for current and possible future conditions, and (d) a large trait databases for Central European plants relevant for this project.
