{ "currentVersion": 10.91, "cimVersion": "2.9.0", "id": 3, "name": "Délimitations des UC du saumon quinnat du sud de la Colombie-Britannique", "type": "Feature Layer", "description": "Unités de conservation (UC) : Une UC s'entend d'un groupe de saumon sauvage suffisamment isolé des autres groupes pour que, s'il venait à disparaître, il soit très peu probable qu'il puisse se rétablir naturellement dans un délai acceptable, p. ex. la durée de vie d'un être humain ou un nombre précis de générations de saumon.\n\nHoltby et Ciruna (2007) ont fourni un cadre pour l\u2019aggrégat des cinq espèces de saumon (genre Oncorhynchus) trouvées sur la côte canadienne du Pacifique dans les unités de conservation propres aux espèces en fonction de trois principales caractéristiques : écotypologie, cycle biologique et génétique. La première étape de la description des unités de conservation repose uniquement sur l\u2019écologie. Les écotypologies utilisées dans ce cadre incluent une caractérisation combinée d\u2019environnements marins d\u2019eau douce et d\u2019eaux à proximité du littoral, dits « zone adaptative conjointe ». Dans la deuxième étape, nous utilisons le cycle biologique, la génétique moléculaire et d\u2019autres caractérisations écologiques pour regrouper ou séparer les unités de la première étape en unités de conservation sous leur forme finale. Il en résulte des unités de conservation qui sont décrites au moyen de l\u2019application commune des trois axes. Il est important de souligner que les unités de conservation se distinguent des autres agrégats du saumon du Pacifique, telles que les unités désignables (UD) en vertu de la Loi sur les espèces en péril ou les zones de gestion.", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 102100, "latestWkid": 3857, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001,
