The traffic linked to globalisation has favoured their involvement in biological invasions that have an impact on local biodiversity, the economy and human health. In Franceville, Gabon, little is known about the rodent community. We therefore studied the composition and distribution of rodents along a gradient highlighting the heterogeneity of the city's landscape. The three habitat types studied showed no difference in small mammal abundance, while the diversity index was higher in the vegetated habitat (SDI = 0.73) compared to the outdoor (SDI = 0.71) and indoor (SDI = 0.45) habitats. Our work shows the importance of vegetal remnants in the city for the maintenance of native species. It also highlights the impact of introduced species on small mammal assemblages and the need for management to reduce the factors of their proliferation. specialized urban rodents introduced rodents community composition habitat gradient landscape heterogeneity central African city GABON 080 102 [Early access] [14 ] 2023 0952-8369 https://www.documentation.ird.fr/hor/fdi:010087611 10.1111/jzo.13063 0952-8369 [F B010087611] https://www.documentation.ird.fr/hor/fdi:010087611 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-06/010087611.pdf IRD - Base Horizon / Pleins textes 2023-06-30 2025-02-24 fdi:010087611 fre
