Wildlife populations are not static. Intrinsic and extrinsic factors affect individuals, which lead to spatiotemporal variation in population density range. Yet, dynamics their drivers rarely documented, due part the inherent difficulty of studying long-term population-level phenomena at ecologically meaningful scales. We studied a recolonizing large carnivore population, wolverine Gulo gulo , across Scandinavian Peninsula over nine years. fitted open-population spatial capture-recapture models noninvasive genetic sampling data collected Norway Sweden estimate annual surfaces drivers. This approach allowed us model sex-specific changes effect landscape-level environmental determinants time. Our results revealed that, as wolverines successfully recolonized many parts historical range Scandinavia, relationship with has changed also found support for responses differences temporal relationships, indicating disproportionate recolonization ability anthropogenic pressures. observed significant female several during study period, suggesting still ongoing expansion whereas males might have already reached limits. These findings show that is recovering from centuries persecution severe contraction. sheds light on challenges carnivores human-dominated landscapes time space.
