Disjunct populations of European vascular plant species keep the same climatic niches
Aim Previous research on how climatic niches vary across species ranges has focused on a limited number of species, mostly invasive, and has not, to date, been very conclusive. Here we assess the d ...
Local temperatures inferred from plant communities suggest strong spatial buffering of climate warming across Northern Europe
Recent studies from mountainous areas of small spatial extent (2500 km(2) ) suggest that fine-grained thermal variability over tens or hundreds of metres exceeds much of the climate warming expected for the coming decades. Such variability in temperature provides buffering to mitigate climate-change impacts. Is this local spatial buffering restricted to topographically complex terrains? To answer this, we here study fine-grained thermal variability across a 2500-km wide latitudinal gradient in Northern Europe encompassing a large array of topographic complexities. We first combined plant community data, Ellenberg temperature indicator values, locally measured temperatures (LmT) and globally…
Distribution of biodiversity in managed landscapes – can remotely sensed data be used to find biodiversity hot-spots?
Management of boreal forests for timber production has caused changes in forest structures and disturbance regimes, which have influenced distribution patterns and abundance for a wide range of organisms. The aim of this study was to evaluate how bird and beetle species composition is influenced by stand age and management history in a heavily managed boreal forest landscape and whether it is possible to find biodiversity hot spots in these landscapes using remotely sensed data. Taxa included was flying and epigaeic beetles, and birds. We first compared the assemblages among stands of three ages: 1) young (8-25 years) and 2) middle-aged (40-58 years) stands regrown after clear-cutting, and …
