Última Ecosystem Modeling for Evaluation of Adaptive Management Policies in the Grand Canyon Ecology and Society Walters, Carl J; University of British Columbia; c.walters@fisheries.ubc.ca; Korman, Josh; Ecometric Research Inc.; jkorman@ecometric.com; Stevens, Lawrence E; Stevens Ecological Consulting; farvana@aol.com; Gold, Barry; The David and Lucile Packard Foundation; bgold@packard.org. An Adaptive Environmental Assessment and Management workshop process was used to assist Grand Canyon scientists and managers in developing conceptual and simulation models for the Colorado ecosystem affected by Glen Canyon Dam. This model examines ecosystem variables and processes at multiple scales in space and time, ranging from feet and hours for benthic algal response to diurnal flow changes, to reaches and decades for sediment storage and dynamics of long-lived native fish species. Its aim is to help screen policy options ranging from changes in hourly variation in flow allowed from Glen Canyon Dam, to major structural changes for restoration of more natural temperature regimes. It appears that we can make fairly accurate predictions about some...

Ano: 2000 First records of introduced carps (Teleostei, Cyprinidae) in the natural habitats of Mirim and Patos Lagoon estuary, Rio Grande do Sul, Brazil Zoologia Garcia,Alexandre M.; Loebmann,Daniel; Vieira,João P.; Bemvenuti,Marlise A.. This is the first record in the wild of occurrence of four carp species (bighead Aristichthys nobilis (Richardson, 1845), common Cyprinus carpio carpio Linnaeus, 1758, silver Hypophthalmichthys molitrix (Valenciennes, 1844), and grass carp Ctenopharyngodon idellus (Valenciennes, 1844)) in the Mirim Lagoon and Patos Lagoon estuary. Our findings reinforce the hypothesis that during periods of elevated rainfall and freshwater discharge, exotic species could be easily transported from overflowed ponds and lakes into the Mirim-Patos Lagoon and then estuarine area.
