摘要: Abstract Urbanization causes considerable alteration across a wide range of ecosystem functions at regional and global scales. These changes could be key drivers habitat stability services in urban greenspaces. The aim this study was to test the influence urbanization on taxonomic functional diversities arthropods different trophic levels. We collected predator spiders, polyphagous rove beetles, decomposer woodlice along rural-suburban-urban gradient by litter sifting. Neither taxonomic, nor diversity (Rao’s quadratic entropy) using morphological trait (body size) ecological traits (habitat affinity, humidity preference, disturbance sensitivity) spiders were significantly gradient. For higher rural sites compared suburban ones, while did not differ between sites. Both than or Detrended canonical correspondence analysis also showed that cause considerably composition spider assemblages, beetle woodlouse assemblages clear separation This pointed out levels may crucial driver responses urbanization. Our results suggest has less harmful effect as they can easily recolonize managed Contrarily, recolonization lower (rove beetles woodlice) into habitats is restricted.
