Última Salmonid introduction in Patagonia: the ghost of past, present and future management Ecología austral Macchi,Patricio J.; Vigliano,Pablo H.. The present structure of the fish fauna of Patagonia has been influenced by natural processes and by the introduction of exotic fsh with varying purposes. An analysis of the introductions between 1904 and 2011 in relation to 54 drainages showed that the differential success of salmonid species introduced into Patagonia is related to human actions, environment, evolutionary history and plasticity of the introduced species as well as to their abiotic and biotic interactions. Throughout time shifting policies have lacked clear goals and mandates, ultimately producing management actions and strategies rarely based on actual knowledge. In recent years two broad general management goals have emerged, conservation of native fsh and economic growth through...

Ecology and Society Waples, Robin S.; NOAA Fisheries Northwest Fisheries Science Center; robin.waples@noaa.gov; Beechie, Tim; NOAA Fisheries, Northwest Fisheries Science Center Environmental Conservation Division; Tim.Beechie@noaa.gov; Pess, George R.; NOAA Fisheries, Northwest Fisheries Science Center Environmental Conservation Division; George.Pess@noaa.gov. Because resilience of a biological system is a product of its evolutionary history, the historical template that describes the relationships between species and their dynamic habitats is an important point of reference. Habitats used by Pacific salmon have been quite variable throughout their evolutionary history, and these habitats can be characterized by four key attributes of disturbance regimes: frequency, magnitude, duration, and predictability. Over the past two centuries, major anthropogenic changes to salmon ecosystems have dramatically altered disturbance regimes that the species experience. To the extent that these disturbance regimes assume characteristics outside the range of the historical template, resilience of salmon populations might be...
