Resumo

Alexandra M. R. Bezerra, Jader Marinho-Filho, and Ana Paula Carmignotto (2011) A review of the distribution, morphometrics, and habit of Owl's spiny rat Carterodon sulcidens (Lund, 1841) (Rodentia: Echimyidae). Zoological Studies 50(5): 566-576. The genus Carterodon Waterhouse, 1848 contains a single species, C. sulcidens (Lund, 1841), restricted to Neotropical savannas and known from a few sites in central Brazil, where it is endemic to the Cerrado biome. Current knowledge about this rare species comes from a handful of specimens deposited in scientific collections. The recent acquisition of additional samples prompted an assessment of the morphological variability in the species. Multivariate analyses of 25 craniodental measurements obtained from 27 whole specimens pooled into 3 geographic samples and representative of all available Carterodon specimens, revealed no morphometric structuring. Two new records were obtained from museum specimens. One extends the species' distribution southward to a new Brazilian state, but many Carterodon localities have lost their natural habitats. While natural history notes indicate no reproductive seasonality, more females than males were captured in both the wet and dry seasons. The species is a habitat specialist with a small litter size, a low reproductive rate, and a high risk of extinction due to habitat loss. http://zoolstud.sinica.edu.tw/Journals/50.5/566.pdf (AU)
