Salvelinus species are one of the most thoroughly studied groups of fishes. Many reasons explain this intense interest in charr biology. Charrs have a Holarctic distribution encompassing many Asian, North American, and European countries and occupy diverse marine and freshwater environments. Furthermore, the current distribution of charr includes areas that were directly influenced by climate and topographic change associated with the many Pleistocene glaciations. Undoubtedly, these conditions have promoted much of the tremendous morphological, ecological, and genetic variability and plasticity within Salvelinus species and they make charr very good models to study evolutionary processes 'in action'. Many charr species also exhibit demographic characteristics such as slow growth, late maturity, and life in extreme environments, that may increase their susceptibility to extinction from habitat changes and overexploitation, especially in depauperate aquatic habitats. This vulnerability makes understanding their biology of great relevance to biodiversity and conservation. Finally, charr are of great cultural, commercial, and recreational significance to many communities, and their intimate linkage with human societies has stimulated much interest in this enigmatic genus. This volume comprises a selection of papers presented at the fourth International Charr Symposium held in Trois-Rivières (Québec, Canada), from 26 June to 1 July 2000. It includes 31 papers on ecological interactions and behaviour, trophic polymorphism, movement and migration, ecophysiology and evolutionary genetics, ecological parasitology, environmental stress and conservation. These studies cannot cover all recent developments in the ecology, behaviour and conservation of Salvelinus species, but collecting them into a special volume should bring attention to current research on this important genus and stimulate further work onSalvelinus species.
Info autore
Pierre Magnan wurde 1922 in Manosque (Basses-Alpes) geboren. Er hat über 20 Bücher veröffentlicht, von denen mehrere in Frankreich und anderen Ländern preisgekrönt, in zahlreiche Sprachen übersetzt und verfilmt wurden. Pierre Magnan lebt noch heute in Manosque; die Provence ist Inspiration und Hintergrund all seiner Romane. Pierre Magnans Bücher bestechen durch die fast greifbare Beschreibung der Landschaft, die Allgegenwart der Jahreszeiten und des Wetters - die Provence in ihrer ganzen Pracht. "Diese Verbrechen und Kommissar Laviolette sind für mich ein Mittel, um eine Stimmung einzufangen, eine Abenddämmerung, ein Morgengrauen über dieser kargen, einsamen, tragischen Landschaft der Haute Provence" (Pierre Magnan).
