16. LISTA REVISADA DE LOS MAMÍFEROS DE ARGENTINA.

Author

Teta, Pablo, Abba, Agustín M., Cassini, Guillermo H., Flores, David A., Galliari, Carlos A., Lucero, Sergio O., and Ramírez, Mariano

Abstract

We present a revised checklist of the mammals of Argentina, incorporating recent taxonomical changes and new records of mammals for the country produced since the publication of a previous list in 2006. We recordered 409 native species, corresponding to 181 genera, 46 families and 12 orders, plus 23 introduced taxa with wild populations. [ABSTRACT FROM AUTHOR]

30. REVISION OF THE SYSTEMATIC STATUS OF PATAGONIAN AND PAMPEAN GRAY FOXES (CANIDAE: Lycalopex griseus AND L. gymnocercus) USING 3D GEOMETRIC MORPHOMETRICS.

Author

Prevosti, Francisco J., Segura, Valentina, Cassini, Guillermo, and Martin, Gabriel M.

Subjects
*FOXES, *SPECIES, *DUSICYON, *MORPHOMETRICS, *ALLOMETRY, SEX differences (Biology)
Abstract

The article presents research on fox species Lycalopex griseus and Lycalopex gymnocercus from northern Patagonia and in most of central and northern Argentina and Patagonia and throughout western Argentina. The study tested the hypothesis that the foxes were from the same species and differences between them were due to clinical variation in size. It discusses the use of geometric morphometrics to determine sexual dimorphism, allometry and goegraphical cranial size and shape variation.

32. THE EXTINCTION OF SOME SOUTH AMERICAN CAMELIDS: THE CASE OF Lama (Vicugna) gracilis.

Author

Cajal, Jorge, Tonni, Eduardo P., and Tartarini, Viviana

Subjects
*BIOLOGICAL extinction, *CAMELIDAE, *LAMA (Genus)
Abstract

The article discusses a research study about the extinction of the Camelidae genera Lama (Vicugna) gracilis in South America, particularly in the low plains of Argentina and Uruguay. A previous study suggests the relation of the distribution of L. vicugna to that of microthermal grammineae groups. Record shows that an unfavorable competence with the subgenus Lama guanicoe in the exploitation on similar niches was the caused of the extinction of L. gracilis. Analysis reveal that both guanacos and vicuña feed on the same food resources and that competition may be the outcome of shared scarce resources. The reduced populations of L. gracilis leading to its extinction is also attributed to the pressure of hunting by paleoindian groups.
