Caracteristiques Spatiales De Taterillus Pygargus Dans Le Sahel Senegalais

Socio-Ecology of Saharan Gerbils, Especially Meriones Libycus

“…This description applies to M. libycus (this study), P. obesus (Daly & Daly, 1974, 1975, and Taterillus pygargus (Poulet, 1972), and is consistent with the less complete information available for M. hurrianae (Fitzwater & Prakash, 1969), M. crassus (Fetter, 1968, and this study), G. pyramidum (this study and unpublished observations), and G. nanus (Kirchshofer, 1958).…”

Spatial Distribution of a Leaf-Eating Saharan Gerbil (Psammomys Obesus) in Relation to Its Food

“…This is hardly the sort of affiliative process implied by "colonialism". Poulet (1972) approached the spatial distribution of another gerbil, Taterillus pygargus of Senegal, rather differently. He concluded that Brought to you by | University of Arizona Authenticated Download Date | 7/12/15 6:48 PM there were "micropopulations" that were reproductive units, called them evidence of a primitive social structure, and strongly implied that a degree of social attraction is demonstrated thereby.…”

Towards a better knowledge of the molar morphology and ecology of extant and fossil grass rats (Muridae:ArvicanthisLesson, 1842)

“…These important differences, especially regarding the higher number of large features quantified in specimens from S2, could be explained by the fact that these specimens were found mainly in deserts, contrary to specimens from S1, which were found in less-arid semi-desertic areas (Abdel Rahman et al, 2008). Even if both populations probably lived in grassy patches in the riparian fringe of the Nile River, living in drier environments would induce a larger consumption of hard and tough items, such as tree bark, rather than fruits (Poulet, 1982), but can also include consumption of insects and ingestion of grit, which might result in larger microwear features. Moreover, some large areas adjacent to the Nile in Sudan are used for agriculture.…”

“…Conversely, the expansion of savanna areas in other periods allowed geographic and demographic expansion of Arvicanthis. After the Early Pleistocene, Galat and Galat-Luong, 1977;Poulet, 1982;Granjon and Duplantier, 2009;Monadjem et al, 2015;<www.iucnredlist. org> repeated dispersals of Arvicanthis populations occurred to the west (Sudano-Guinean savannas) and to the south (Masai steppe) (Bryja et al, 2019), but also possibly to the north, as suggested by the first appearance of Arvicanthis remains in a northern African site dating from the Early Pleistocene (Jebel Ressas 8, Tunisia; Mein and Pickford, 1992).…”
