Response of arthropod species richness and functional groups to urban habitat structure and management [PDF]

open access: yes, 2018
Urban areas are a particular landscape matrix characterized by a fine-grained spatial arrangement of very diverse habitats (urban mosaic). We investigated arthropods to analyse biodiversity-habitat associations along five environmental gradients (age ...
