The study is a contribution to the knowledge of Rodents and Shrews diversity in Yasikia forest, located at 31 Km from Kisangani, on the road towards Opala. On transects, Rodents and Shrews were sampled using the protocol with [xPF, ySH]. A total of 13 sampling lines were observed during 15 days (from March 26 to 11 April 2015). As results, we collected 74 shrews, belonging to two genera at least 9 species; 68 rodents which represent 9 genera and 12 species. In total, we collected 145 small mammals, with a trapping effort of 6478 trap-nights. The specific biodiversity and trappingsuccess showed that Pitfall traps are the most efficient to capture Shrews. It also catches small Rodents and adult such as N.cf.grata, and other adults’ rodents as Praomys genera, but with reduced number. Sherman traps are more effective to catch Rodents. They also catch shrews in reduced number. The trappings were conducted in three habitats. In the primary forest G. dewevrei (EC = 1060 night-traps, 50 specimens, 14 species, and TS = 4.72%), mixed primary forest (EC = 1500 night-traps, 69 specimens, 15 species, and TS = 4.6%) and fallow land (EC = 440 night-traps, 23 specimens, 9 species, and TS = 5.23%). No new species was announced but rather the presence of three endemic species of which two (C. Goliath and L. huttereri) are rare.

Abstract: (french)
Cette étude est une contribution à la connaissance de la biodiversité des Rongeurs et des Musaraignes dans la forêt de Yasikia, située à 31 Km de Kisangani, sur la route Opala. Un piégeage sur 13 lignes au moyen du dispositif [xPF, ySH] a été effectué pendant 15 jours de relevé, soit du 26 mars au 11 avril 2015. Cet échantillonnage a permis d’obtenir 145 spécimens dont 74 Musaraignes, réparties en deux genres et 9 espèces ; 68 Rongeurs répartis en 9 genres et 12 espèces pour un effort de capture de 6478 nuits-pièges. La biodiversité spécifique et le trapping success montrent que les pièges Pitfall sont les mieux appropriés pour capturer les musaraignes. Ils capturent aussi des Rongeurs de petite taille tels que N. cf. grata, des jeunes et adultes d’autres Rongeurs du genre Praomys, mais avec des effectifs réduits. Les pièges Sherman quant à eux, s’avèrent efficaces pour capturer des Rongeurs. Ils capturent aussi de Musaraignes mais en petit nombre. Les piégeages étaient effectués en trois habitats : la forêt primaire à Gilbertiodendron dewevrei (EC = 1060 nuit-pièges, 50 spécimens, 14 espèces et TS = 4,72%), de la forêt primaire mixte (EC = 1500 nuit-pièges, 69 spécimens, 15 espèces et TS = 4,6%) et enfin de la jachère (EC = 440 nuit-pièges, 23 spécimens, 9 espèces et TS=5,23%). Aucune espèce nouvelle n’a été signalée mais plutôt la présence de trois espèces endémiques dont deux (C. goliath et L. huttereri) sont rares.
