Salvelinus species are probably the most completely studied teams of fishes. Many purposes clarify this excessive curiosity in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and eu nations and occupy varied marine and freshwater environments. in addition, the present distribution of charr comprises components that have been without delay motivated by way of weather and topographic swap linked to the numerous Pleistocene glaciations. absolutely, those stipulations have promoted a lot of the large morphological, ecological, and genetic variability and plasticity inside of Salvelinus species and so they make charr first-class versions to review evolutionary tactics 'in action'. Many charr species additionally express demographic features reminiscent of gradual progress, overdue adulthood, and lifestyles in severe environments, that could raise their susceptibility to extinction from habitat adjustments and overexploitation, in particular in depauperate aquatic habitats. This vulnerability makes figuring out their biology of serious relevance to biodiversity and conservation. eventually, charr are of serious cultural, advertisement, and leisure value to many groups, and their intimate linkage with human societies has encouraged a lot curiosity during this enigmatic genus. This quantity includes a variety of papers awarded on the fourth overseas Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to one July 2000. It contains 31 papers on ecological interactions and behavior, trophic polymorphism, stream and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental tension and conservation. those stories can't hide all contemporary advancements within the ecology, behaviour and conservation of Salvelinus species, yet accumulating them right into a particular quantity may still carry awareness to present learn in this vital genus and stimulate additional paintings on Salvelinus species.
