“…Information on distribution and habitat tolerances of mammals was derived from the following sources: Morocco—Aulagnier & Thevenot (1986); Spain—Macdonald & Barrett (1993); Israel—Cheylan (1990a), Yom‐Tov & Kadman (1998); Senegal—Meester & Setzer (1971), Happold (1987), Duplantier & Granjon (1991). Further information on habitat tolerances came from Hufnagl (1972) and Kowalski & Rzebik‐Kowalska (1991).…”

The nonmarine mammal fauna of the Maghreb region of north‐west Africa is related to that from three potential source areas: the northern Palaearctic (Europe and south‐west Asia; here referred to as the European fauna), subsaharan Africa (the African fauna) and the arid Palaearctic (Sahara Desert: the desert fauna). On the basis of geographical distribution patterns, this fauna divisible into two groups: the bats, whose affinities are most closely related to southern Europe and south‐west Asia, and nonflying species, most closely related to subsaharan Africa but with an appreciable northern Palaearctic element. These affinities are even more pronounced if desert fauna are removed from the analysis. The nonflying European fauna probably colonized via south‐west Asia and north Africa, rather than direct from western Europe. The results demonstrate that terrestrial habitat barriers are less of an impediment to dispersal, for all mammals except bats, than even narrow stretches of water. The fauna of the Maghreb may be undergoing faunal relaxation, following immigration from tropical Africa and south‐west Asia during mesic phases in the Late Pleistocene and early Holocene.

“…Some of the species captured in this transect are known from Senegal and are present in the Hubert et al (1973) list updated by Duplantier and Granjon (1992) (Table V). By comparison with Mali, one notes the absence of sahelo-sudanian elements such as Taterillus, Gerbillus spp., M. haussa, M. musculoides but some sudanian-guinean taxa like A. ansorgei, L. striatus, T. guineae, M. mattheyi that are common between both countries.…”

We compiled the first taxonomic inventory of rodents inhabiting the region from northwestern Guinea to coastal Guinea and this enabled an improved understanding of the rodent fauna of this unexplored region at the western margin of the guineo-congolese forest block. Through standard cytogenetic and morphological analyses we described the presence of two sibling species of the genus Mastomys in West Africa. We report here the first records for Guinea of Arvicanthis ansorgei and M. mattheyi. Our data indicated an extension of the known distribution of Lemniscomys striatus to include the western region of the range of Lophuromys cf. sikapusi. A comparison between southern Senegal, southern Mali, Ivory Coast and eastern Guinea assemblages shows some differences in the rodents between eastern and western Guinea as well as with the surrounding countries. It appears that coastal Guinea could correspond to a transition zone between forest and savanna but this region appears to be ecologically highly degraded in terms of its small mammal communities. Rattus rattus is found in all sampled localities but Mus musculus is restricted to one locality where it was the dominant species of the assemblage. Our study highlights the importance of surveys of rodent biodiversity in unexplored zones.

“…This work can be added to that already available for the other African countries (e.g., review in Happold 1987, p. 297 and 298;Gautun et al 1985;Duplantier and Granjon 1992;Duplantier et aL, 1997;Robbins and Van der Straeten 1996;Mess and Krell 1999). Such large data sets are valuable for defining biogeographical areas, and for studying their dynamics and evolution.…”

We here present an inventory of rodents from Niger, mainly based on cytotaxonomic data because of the presence of many groups providing sibling species. A total of 39 species are listed, one of which is a new chromosomal form (Talerillus sp.). Moreover, three other cytotypes already described but still not specifically attributed were found (Mastomys sp., Acomys sp. and Tatera sp). New karyotypic data are presented for Gerbillus nancillus, Graphiurus cf. pan^us, Massouteria mzabi, and Xerus erythropus. Once again, the efficiency of cytotaxonomy for small mammals inventories is enhanced.Specific distribution maps of poorly known species are thus completed. No clear gradients could be observed between what is currently defined as the West and the East African faunas. The distributions are mainly structured in a latitudinal manner. The Air massif appears as a continuous prolongation of the Sahelian area, rather than as a Sahelian refuge in the Sahara. Five biogeographical groups of species were distinguished: 1) a Sudanian group in the area receiving less than 700 mm rainfall, 2) a group of very widespread species largely overlapping the Sudanian (more than 700 mm rainfall) and the Sahelian areas, and sometimes including some Saharan localities, 3) a typical Saharan group, 4) some species infeoded to the mountainous Saharan area, and 5) few strictly commensal species. A global southward extension of several taxa confirms the desertification of the Sahel, as a result of both natural global warming and human activities.Resume. -Nous avons realise un inventaire des rongeurs du Niger qui s'appuie essentiellement sur des donnees cytotaxonomiques non ambigues ä cause de la presence de nombreux complexes d'especes jumelles. Trente neuf especes ont pu etre recensees, Tune d'entre-elles correspondant ä une nouvelle forme chromosomique de Taterillus. De plus, 3 cytotypes toujours sans attribution specifique ont ete retrouves (Mastomys sp., Tatera sp. et Acomys sp.) et des donnees caryotypiques nouvelles sont presentees pour Gerbillus nancillus, Graphiurus cf. parvus, Massouteria mzabi et Xerus erythropus.

Aucun gradient n'est observe entre les faunes cTAfrique occidentale et celles d'Afrique Orientale, les especes se repartissant essentiellement en fonction de la latitude. Le massif de 1'A'ir apparait plutot comme un prolongement de la zone sahelienne que comme un refuge sahelien dans le Sahara. Parmi les especes de rongeurs inventoriees, cinq grands groupes biogeographiques peuvent etre distingues: 1) des especes infeodees ä la zone soudanienne recevant moins de 700 mm; 2) un groupe d'especes tres largement reparties de la zone soudanienne (plus de 700 mm) au nord de la zone sahelienne, et incluant parfois des localites sahariennes; 3) des especes typiquement sahariennes; 4) des especes infeodees ...
