| genetic structure in a solitary rodent (ctenomys talarum): implications for kinship and dispersal. | the genetic structure of a population provides critical insights into patterns of kinship and dispersal. although genetic evidence of kin structure has been obtained for multiple species of social vertebrates, this aspect of population biology has received considerably less attention among solitary taxa in which spatial and social relationships are unlikely to be influenced by kin selection. nevertheless, significant kin structure may occur in solitary species, particularly if ecological or life ... | 2005 | 15969731 |
| redescription of trichuris pampeana (nematoda: trichuridae) from the south american subterranean rodent ctenomys talarum thomas, 1898 (rodentia: octodontidae). | trichuris pampeana suriano and navone, 1994 (nematoda: trichuridae) is redescribed from voucher specimens from the type host ctenomys azarae thomas, 1903 (rodentia: octodontidae) and from parasites collected from 2 populations of the subterranean rodent c. talarum thomas, 1898 from mar de cobo and necochea, buenos aires province, argentina. after a revision of these nematodes, it was confirmed that the following characters were not considered in the original description: bacillary band, cells fr ... | 2005 | 15856885 |
| the role of the subterranean rodent ctenomys talarum (rodentia: octodontidae) in the life cycle of taenia taeniaeformis (cestoda: taeniidae) in urban environments. | this work is the first report of subterranean rodent ctenomys talarum (rodentia: octodontidae) as intermediate host of taenia taeniaeformis in urban areas of mar de cobo (buenos aires province, argentina) and to experimentally reproduce in domestic dogs the adult stage of this parasite. prevalence, mean abundance and mean intensity of infection with t. taeniaeformis larvae in the liver and peritoneal cavity of c. talarum were 64%, 15.3 and 9.8, respectively. ten adults of t. taeniaeformis were o ... | 2004 | 15158554 |
| dna fingerprinting reveals polygyny in the subterranean rodent ctenomys talarum. | dna fingerprinting was used to characterize patterns of paternity in two populations of ctenomys talarum from buenos aires province, argentina. the multilocus probe pv47-2 was used to detect variation in genomic dna extracted from 12 females, their 32 offspring, and 14 putative sires. for 11 out of 12 litters examined, a single male capable of providing all nonmaternal bands was identified. within each study population, individual males sired more than one litter, suggesting that c. talarum is p ... | 1999 | 10564459 |
