| comparative chromosome analysis (r- and c-bands) of two south african murid species, lemniscomys rosalia and rhabdomys pumilio (rodentia, murinae). | we carried out a comparative chromosome analysis (r- and c-bands) on two south african murid rodent species, lemniscomys rosalia and rhabdomys pumilio, whose banded karyotypes are reported here for the first time. the study revealed that, in spite of minor differences in diploid number and the number of autosomal arms (48 vs. 46 and 58 vs. 60, respectively), these species differ by at least 10 structural rearrangements, comprising seven robertsonian translocations (two of which share monobrachia ... | 1999 | 10640814 |
| feeding patterns of immature stages of hyalomma truncatum and hyalomma marginatum rufipes on different hosts. | in this study we examine the feeding patterns of immature stages of hyalomma truncatum and hyalomma marginatum rufipes ticks on different hosts. larvae of h. truncatum developed through a three-host pattern on two species of field mice, rhabdomys pumilio and lemniscomys rosalia. on guinea-pigs, both hyalomma species followed a mixed two-host and three-host pattern, with the latter route being preferred, since more than 70% of the fully fed larvae dropped off from their hosts. h. truncatum was a ... | 2000 | 11110240 |
| evidence of cryptic speciation in mesostigmatid mites from south africa. | laelaps giganteus and laelaps muricola (mesostigmata; laelapidae) are widespread and locally abundant host generalists on small mammals in southern africa. the large host range and complex life history of these ectoparasites may allude to possible intraspecific cryptic diversity in these taxa. to assess genetic and morphological diversity in l. giganteus and l. muricola, we sampled 228 rodents at eight localities in south africa. this sample included nine previously recorded host species and on ... | 2014 | 24923552 |
| morphometric analysis of the gastrointestinal tract of four african muroid rodent species (rhabdomys dilectus, rhabdomys pumilio, aethomys chrysophilus, and lemniscomys rosalia). | several muroid rodent species are distributed throughout southern africa. some species are reportedly classified as opportunistic omnivorous rodents consuming plant, seed, and insect material. this study aims to provide a detailed morphometric analysis of the gastrointestinal tract (git) of four such omnivorous species, including stomach content analysis. fixed git specimens (n = 5 of each) of rhabdomys dilectus (mesic four-striped grass mouse), rhabdomys pumilio (xeric four-striped grass mouse) ... | 2018 | 30187940 |
