Abstract
The masked palm civet (Paguma larvata) is a medium-sized arboreal carnivore distributed across East and Southeast Asia, including Taiwan, where it inhabits both lowland forests and urban areas. Despite its ecological importance, the genetic structure and habitat connectivity of P. larvata in Taiwan remain understudied. This study used the mitochondrial cytochrome b gene and ecological niche modeling to investigate population structure, historical connectivity, and habitat suitability. We estimated genetic diversity and population dynamics, examined potential geographic or ecological barriers influencing gene flow, and explored historical links between Taiwanese and Japanese populations using newly collected and previously published samples. In addition, we identified environmental factors shaping suitable habitats across Taiwan. Our results revealed low genetic differentiation across Taiwan, suggesting extensive connectivity likely facilitated by the species’ adaptability to diverse and human-modified environments. Phylogenetic analysis showed a monophyletic relationship between Taiwanese and Japanese populations, supporting Taiwan as a primary source of introduction. Niche modeling highlighted the importance of bushland cover and temperature range in determining habitat suitability, with suitable areas concentrated in lowland regions. These findings underscore the ecological flexibility of P. larvata and offer valuable insight into its population dynamics and landscape-level connectivity in Taiwan. © The Author(s) under exclusive licence to Deutsche Gesellschaft für Säugetierkunde 2026.
