ABSTRACT: 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.
