Abstract Protected areas are essential tools for reducing loss of global biodiversity. To fulfill their ecological functions, protected must be connected to surroundings, a requirement that is difficult meet in landscapes intensively disturbed by anthropogenic activities. Therefore, protecting movement corridors at the edges crucial, especially species with broad habitat needs, such as American marten ( Martes americana ). However, selection and space use patterns dynamic processes, so we could expect functional connectivity would vary temporally response changing environmental conditions levels human In this study, aimed predicting location Forillon National Park its periphery during two contrasted periods (snow‐free: May–November; snow‐covered: December–April). We used “seasonal” resource functions identify core (interpreted circuit “nodes”) CircuitScape delineate between them based on electrical theory. Habitat differed periods, martens avoiding open areas, high elevations road proximity snow‐free period, while closer secondary roads but selecting primary housing structures snow‐covered period. Consequently, partially periods. Functional was favored presence forest patches both being constrained environments, Our study highlights importance modeling fine temporal scales order provide requirements each period annual cycle.

Les aires protégées peuvent contribuer à réduire la perte de biodiversité en maintenant des fonctions écologiques clés. Atteindre cet objectif implique d’identifier et protéger les corridors déplacement favorables faune périphérie protégées. Nous avons aidé Parcs Canada pour localiser aux déplacements martre d’Amérique ( Martes americana ) dans le parc national Forillon sa périphérie. Puisque comportement animaux peut changer selon variations conditions environnementales, nous effectué exercice durant 2 périodes contrastées : sans neige (mai-novembre) avec (décembre-avril). utilisé données télémétriques GPS caractériser patrons sélection d’habitats saisonniers, lesquels ont permis modéliser résistance du paysage parcelles connectivité. ensuite théorie circuits électriques délimiter entre ces parcelles. martres évitaient milieux ouverts, altitudes élevées proximité routes période neige, alors qu’elles secondaires, mais sélectionnaient zones proches principales bâtiments neige. La localisation variait aussi connectivité augmentait présence forêts régénération (21-60 ans) résineuses matures (> 60 diminuait ouverts. Notre étude martres, souligne l’importance considérer saisonnières lors modélisation fonctionnelle.
