| Summary: | International audience In order to better characterize small terrestrial mammals biodiversity in anthropized habitats of central and coastal Morocco versus natural habitats, we performed a fieldwork inventory from April 2010 to May 2011 in 19 localities for 8336 night traps. In total, we collected 897 specimens belonging to 15 terrestrial small mammals, including 833 Rodentia, 56 Soricomorpha, 6 Erinaceomorpha, 2 Macroscelididea and one Carnivora. The trapping success was highly variable (from 1.6 to 80%) and in an average of 10.7%. Among the rodents, Mus spretus and Apodemus sylvaticus were the two most abundant species (64%), followed by Meriones shawii (16%), Mus musculus (5%), Rattus rattus (4%), Gerbillus campestris (4%) and at the occasion Lemniscomys barbarus (2%) and Eliomys munbyanus (1%). Crocidura russula was the single shrew collected while Atelerix algirus, Elephantulus rozeti and Mustela nivalis were trapped only accidentally. The highest diversity was recorded in cultivated areas (up to 7 species) while natural forests and lagoons yielded between 2 and 4 species. Inside houses, the diversity varied between 2 to 5 species. A correspondence analysis, performed on the whole data set, highlighted the correlation between abundance of A. sylvaticus and protected forest environments and between Mus spretus and cultivated areas and degraded forests. These results are in agreement with previous data from the southern Mediterranean basin. Afin de mieux caractériser la biodiversité des petits mammifères terrestres (rongeurs, musaraignes) des zones anthropisées du Maroc central et côtier par rapport à celle des milieux naturels, une campagne d’inventaires ciblés a été effectuée d’avril 2010 à mai 2011 dans 19 localités représentant un effort de 8386 nuits-pièges. Au total, 897 spécimens appartenant à 15 espèces de micromammifères terrestres ont été capturés : 833 rongeurs, 56 soricomorphes, 6 érinacéomorphes, 2 macroscelides et 1 carnivore. Les rendements de capture, très variables (de 1,6 à 80%), ont été ...
