Subject(s): Biodiversity | Conservation | Amphipoda | Crustacea | Drainage Connection | Imprevious Area | Road Runoff | Stormwater | Threatened Invertebrate | Urbanization In: Biodiversity and Conservation 13(4)Summary: The general hypothesis that catchement urbanization explained the distribution of the threatened, stream-dwelling amphipod Austrogammarus australis (listed under the Vicorian Flora and Fauna Guarantee Act 1988) was tested using several survey of 58 sites in streams draining the Dandenong Ranges on the eastern fringe of Melbourne, Victoria, Australia. More specifically, four catchement-scale elements of urban land, hypothesized as sources of stress to recieving streams, were separated: catchement imperviousness, drainage connection (proportion of impervious areas connected to streams by stromwater pipes), density of unsealed roads and density of septic tanks. The separation of urban land use into attributes thatcharacterize likely stressor sourse provides a useful framework for assessing and prioritizing the most appropriate management actions to minimize urban-related stresses to aquatic biota.| Item type | Current location | Call number | Status | Date due | Barcode |
