| Paternity testing and behavioral ecology: A case study of jaguars (_Panthera onca_) in Emas National Park, Central Brazil | |
| 2006 Genetics and Molecular Biology (29): 735-740 | |
We used microsatellite loci to test the paternity of two male jaguars involved in an infanticide event recorded during a long-term monitoring program of this species. Seven microsatellite primers originally developed for domestic cats and previously selected for _Panthera onca_ were used. In order to deal with uncertainty in the mother's genotypes for some of the loci, 10000 values of Wwere derived by simulation procedures. The male that killed the two cubs was assigned as the true sire. Although the reasons for this behavior remain obscure, it shows, in principle, a low recognition of paternity and kinship in the species. Since the two cubs were not very young, one possibility is that the adult male did not recognize the cubs and killed them for simple territorial reasons. Thus, ecological stress in this local population becomes a very plausible explanation for this infanticide, without further sociobiological implications. |
