| Little is known about the use of feces in scent marking by small wildcats. We analyzed the characteristics of 357 Geoffroy's cat, Leopardus geoffroyi, defecation sites in five protected areas of Argentina. Defecation sites were mainly found in trees (47.6%) or on the ground (38.1%), and the frequency of occurrence of the types of sites differed between areas. Almost half (47.3%) of defecation sites were latrines, with 6.1 ± 3.6 (mean ± SD) feces each. Geoffroy's cats were flexible in the choice of defecation sites, but mainly deposited feces in latrines located in conspicuous sites. These results suggest that Geoffroy's cats use feces in olfactory/visual communication. |

| Para investigar los factores que afectan la selección de madrigueras de Conepatus chinga, identificamos y caracterizamos 199 (machos: n = 108, hembras: = 91) madrigueras utilizadas por siete zorrinos equipados con radiotransmisores en el periodo comprendido entre agosto de 2002- octubre de 2005, en un área protegida en los pastizales pampeanos de Argentina. Frecuentemente los zorrinos reutilizaron sus madrigueras (25,1%), sin encontrarse diferencias significativas entre ambos sexos. Aunque los zorrinos comunes son considerados animales solitarios nuestros resultados indican que tanto machos como hembras pueden compartir las madrigueras, presumiblemente en la época de apareamiento. Las madrigueras no estuvieron homogéneamente distribuidas dentro de las... |

| Abstract To investigate the evolution and biogeography of an endemic group of South American foxes, we examined mitochondrial DNA control region sequences for 118 individuals belonging to all six extant species of the genus Lycalopex. Phylogenetic and molecular dating analyses supported the inference that this genus has undergone a very recent and rapid radiation, stemming from a common ancestor that lived ca. 1 million years ago. The Brazilian endemic L. vetulus was supported as the most basal species in this genus, whereas the most internal group is comprised by the recently diverged (ca. 350,000 years ago) Andean/Patagonian species L. griseus and L. culpaeus. We discuss the inferred phylogenetic relationships and divergence times in the context of the... |
