Understanding landscape barriers to connectivity is essential for wildlife
conservation. Rivers may restrict movement and gene flow in brown bears
(Ursus arctos), yet their impact remains unclear. Using SNP-genotypes from
519 individuals in northern Sweden, we examined sex-specific dispersal and
genetic structure relative to rivers. Males dispersed farther and crossed
rivers more often than females, indicating rivers act as semipermeable
barriers primarily for females. Genetic structure was weak for females and
absent for males.
