Abstract

\n

Species distri bution changes associated with human-mediated climate change have importan t consequences on ecosystems and human well-being. Despite mounting eviden ce\, our knowledge of the redistribution of life on Earth is still incompl ete with only 0.6% of the described biodiversity on Earth for which range shifts have been documented. I will present the BioShifts databa se which contains 30\,534 observations of velocity of range shifts (VRS) f or 12\,415 taxa\, covering 56 taxonomic classes and 20 phyla across both t errestrial and marine systems. This database is clearly biased towards mor e VRS data for mobile ectotherms\, iconic endotherms and seed-bearing plan ts. Similarly\, a strong geographical bias is noticeable towards the most developed regions in the World. Contrary to former meta-analyses and quant itative syntheses on climate-induced species range shifts\, I will show th e extreme variability in the magnitude and direction of VRS values that is hiding behind averages across broad taxonomic groups (e.g.\, amphibians\, arthropods\, birds\, insects\, mammals\, molluscs and plants) or position within the geographic range (i.e.\, trailing edge\, centroid of the range and leading edge). I will also show that VRS values do not necessarily co nform to the observed values in the magnitude and direction of velocity of isotherm shifts (VIS)\, suggesting other determinants behind the great re distribution of life on Earth.
