Abstract: Our work entitled: Diversity of Shrews (Soricomorpha: Mammalia) in the Kandolo Forest Reserve (Maniema Province, DR Congo) aims to assess the biodiversity of shrews in the Kandolo Forest Reserve while comparing the specific diversity during two capture sessions and in the two prospected habitats Mixed Primary Forest (FPM) and Primary Forest at Gilbertiodendron dewevrei (FPG). Finally, assess the distribution of Shrews in the two habitats (FPG and FPM) prospected by sex. These objectives have been achieved. Only one method was used in the field, the only in-line trapping using two types of traps including Sharmen and Pitfall. After processing the data, the results presented 51 Soricomorphs during our outings. The first capture session carried out in the FPM presents 20 individuals of soricomorphs including: Crocidura cf. littoralis and Scutisorex somereni are the most represented with 6 individuals captured or 30 % and Crocidura cf. ludia, Crocidura dolichura and Crocidura hildegardeae which are the least represented with a score of an individual captured, ie 5 %. On the other hand, during the second session carried out in the FPG, 31 individuals were captured where Crocidura cf. olivieri is the most represented with 11 carcasses, ie 35.48 % and Crocidura caliginea, Crocidura latona and Crocidura ludia are the least represented with a score of one specimen, ie 3.23 %. By evaluating the specific richness for the two different habitats, it appears that there is not a significant difference between the stands of Shrews (Kuskal-Walis test, H = 0.082; p = 0.76). Finally, the sex distribution of the shrews captured in the two habitats during the two sessions, it appears that, in all the habitats, the shrews sampled are not distributed equally by sex. On the one hand, males dominate over females in FPG (67.7 % of males against 32.3 % of females) and on the other hand, females dominate over males in FPM (80 % of females against 20 % of males).
