Salvelinus species are some of the most completely studied teams of fishes. Many purposes clarify this extreme curiosity in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and eu international locations and occupy different marine and freshwater environments. moreover, the present distribution of charr comprises parts that have been without delay motivated by way of weather and topographic switch linked to the numerous Pleistocene glaciations. unquestionably, those stipulations have promoted a lot of the super morphological, ecological, and genetic variability and plasticity inside Salvelinus species and so they make charr excellent versions to check evolutionary strategies 'in action'. Many charr species additionally express demographic features reminiscent of gradual development, past due adulthood, and lifestyles in severe environments, which 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 significant cultural, advertisement, and leisure value to many groups, and their intimate linkage with human societies has motivated a lot curiosity during this enigmatic genus. This quantity contains a range of papers awarded on the fourth foreign Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to at least one July 2000. It contains 31 papers on ecological interactions and behavior, trophic polymorphism, flow and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental pressure and conservation. those reports can't hide all fresh advancements within the ecology, behaviour and conservation of Salvelinus species, yet gathering them right into a specified quantity may still deliver awareness to present learn in this very important genus and stimulate additional paintings on Salvelinus species.
