Distance decay 2.0 – a global synthesis of taxonomic and functional turnover in ecological communities
AbstractUnderstanding the variation in community composition and species abundances, i.e., β-diversity, is at the heart of community ecology. A common approach to examine β-diversity is to evaluate directional turnover in community composition by measuring the decay in the similarity among pairs of communities along spatial or environmental distances. We provide the first global synthesis of taxonomic and functional distance decay along spatial and environmental distance by analysing 149 datasets comprising different types of organisms and environments. We modelled an exponential distance decay for each dataset using generalized linear models and extracted r2 and slope to analyse the streng…

Water as a multifaceted environmental filter of tundra vegetation
The hydrological cycle of tundra has intensified due to accelerated environmental changes. Climatic changes affect tundra vegetation by altering water conditions (1). Plant-available water mediates climate change impacts, namely against rising temperatures and changing snow dynamics (2). Vegetation is limited by water resources, but water forms also major stress and disturbance. However, climate change impact studies often cover water inadequately in cold regions, which are assumed to be energy-limited ecosystems (3). Thus, we used statistical modelling methods to test if the inclusion of different water factors improved species distribution, species richness, and community composition mode…
