I conducted a small mammal trapping study in the central Paraguayan Chaco region of South America to investigate habitat selection by small mammals at different spatial scales. Small mammals were collected in forest, successional thorn scrub, pasture, and crop fields representing both relatively undisturbed habitats and agroecosystems. A total of 1,089 small mammals representing 13 species were captured during 23296 trap nights. Pastures had the highest species richness as well as the highest number of captures. Some small mammal species such as Calomys laucha and Akodon toba were captured in a variety of habitats whereas others like Holochilus chacarius and Bolomys lasiurus were captured almost exclusively in pastures. Principal components analysis distinguished small mammal species primarily associated with agricultural habitats (e.g. Calomys spp.) from those associated with more wooded habitats (e.g. Graomys griseoflavus and Oligoryzomys chacoensis). These results corroborate other studies on habitat use by small mammals in this region, but with some notable exceptions, such as the first documentation of high densities of Calomys musculinus in western Paraguay.
The Late Pleistocene mammal record of Quebrada Quereo Formation: biogeography, biostratigraphy and paleoclimatic inferences. This paper describes the fossil fauna recovered from the Quebrada Quereo Formation (Late Pleistocene – Holocene) located at Choapa Province, IV Region, Chile. In this formation, two cultural levels (Quereo I y II) with Pleistocenic fauna were detected. The remains identified include living species (Dusycion cf. D. culpaeus), as well as extinguished fauna (Palaeolama sp., Antifer sp., Equus [Amerhippus] sp., cf. Panthera onca, Milodontidae, and Gomphoteriidae). For each of these, we present taxonomic, paleogeographic and paleoclimatic remarks. The possible presence of P. onca in Quebrada Quereo Formation constitutes the first evidence of a locally extinct felid outside the Patagonic area of Chile. The identified faunal assemblage presents differences with those recorded in Argentinean territory; which is explained by the presence of the Cordillera de los Andes. The Chilean paleofaunistic assemblages, therefore, are related to those found in Bolivia and the Andean occidental sector in general, although some enrichment with taxa from the oriental side of the range is not discarded.
