Altered Ecological Flows Blur Boundaries in Urbanizing Watersheds
The relevance of the boundary concept to ecological processes has been recently questioned. Humans in the post-industrial era have created novel lateral transport fluxes that have not been sufficiently considered in watershed studies. We describe patterns of land-use change within the Potomac River basin and demonstrate how these changes have blurred traditional ecosystem boundaries by increasi...
متن کاملCommunity Values and the Long-term Ecological Integrity of Rapidly Urbanizing Watersheds
Until recently, managing water quality in a watershed was widely viewed as a matter of installing (and operating) an infrastructure to deal with pollution from industrial and domestic urban sewage. Data on discharges and pollutant loads from a population equivalent, generated or collected from within a government bureaucracy, were used by professional engineers to specify the level of infrastru...
متن کاملPredicting ecological connectivity in urbanizing landscapes
Nearly half the world's population lives in urban centers, and these areas are increasingly important components of regional and global land cover. However, their ecological attributes are often overlooked, despite the presence of species, ecosystem services, and risks associated with the spread of pests or threatening processes such as fire. Movement and dispersal of organisms contribute to sp...
متن کاملThe Application of Ecological Principles to Urban and Urbanizing Landscapes
gene sequencers through advanced computers and networking to global-observing satellites-coupled with keen scientific curiosity present an opportunity for unprecedented advances. Together, we can make ecological science a mainstay of sustainability. While pursuing that goal, we need to ensure that our best efforts are made available to society along the way. The time of science remaining in its...
