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...

A comparison of three methods to estimate variations in the relative abundance of moutain vizcachas (Lagidium viscacia) in the High Andes ecosystems
Provedor de dados: 81
Autores: Lucherini,Mauro; Reppucci,Juan I.; Luengos Vidal,Estela.
Mountain vizcachas are large rodents that constitute the main prey of the High Andes meso-carnivores. We compared the line transect pellet count, observation rate and photographic rate methods to estimate the relative abundance of Mountain vizcachas in the High Andes ecosystems. Although a more formal validation based on the comparison with true abundances is desirable, our results suggested that these simple and affordable indices are promising methods, especially if protocols and sampling efforts are carefully standardized. We recommend the use of photographic rates, which are likely to provide the most reliable estimates, especially where Mountain vizcachas are active at night.

Denning ecology of conepatus chinga (carnivora: mephitidae) in a grassland relict of central Argentina
Provedor de dados: 81
Autores: Castillo,Diego F; Luengos Vidal,Estela M; Caruso,Nicolás C; Lucherini,Mauro; Casanave,Emma B.
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...

A preliminary revision of knowledge status of felids in Argentina
Provedor de dados: 81
Autores: Lucherini,Mauro; Soler,Lucía; Luengos Vidal,Estela.
Argentina is the host of 10 wild felids (28% of the world total). Although the Cat Specialist Group Action Plan has classified the conservation status of Argentine cats as relatively good, the ranking was based on a largely incomplete database for at least 80% of the species. Here we review the current status of knowledge and research effort of Argentine cats, compare it with their distribution, habitat association and conservation status and provide guidelines for their future research. Between 1990 and 2000, cat research has received increasing attention in Argentina. Twenty-four projects have been carried out, but only 13 studies are still in progress. A rank of research priority has been calculated for each felid and ecoregion. Our analysis showed that...

Characteristics of defecation sites of the Geoffroy´s cat Leopardus geoffroyi
Provedor de dados: 81
Autores: Soler,Lucía; Lucherini,Mauro; Manfredi,Claudia; Ciuccio,Mariano; Casanave,Emma B.
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.
