The present study analysed the taphonomic characteristics of small mammal bone accumulations produced by small felids in an area from the central Monte Desert (Mendoza, Argentina). In order to provide criteria to identify the role that these predators had in the formation of zooarchaeological assemblages, the anatomical representation, bone breakag...

The xenarthrans are the only group of mammals that originated in South America; there are 31 living species: six sloths, four anteaters, and 21 armadillos. In Argentina, 18 species of xenarthrans were cited. The objectives of this study were to compile the existing information on the distribution of the xenarthrans of Argentina, to use species dist...

In this study we examined predation by small felids upon small and medium-sized prey mammals in the central region of the Monte Desert. We analyzed the degree of vulnerability of prey mammals in relation to their habitat use patterns, modes of locomotion and age classes. Medium and small rodents were the predominant prey in the diet of small cats....

In this study, we combine species distribution models with a reserve selection approach to assess the degree of representation of xenarthrans in the existing protected area network of Argentina, and to identify conservation priority areas that may help expand the current system. Species distribution models were developed from species’ occurrence re...

Lethaia, Vol. 44, pp. 93–101.This study examines the limb bone proportions and strength of glyptodonts (Xenarthra, Cingulata). Two methods are used to estimate the body mass and location of the centre of gravity of the articulated spec...

En este trabajo se listan los mamíferos del arroyo Perucho Verna, provincia de Entre Ríos, Argentina. El área de estudio está localizada en el centro-este de Entre Ríos; fitogeográficamente, la región está incluida en la Provincia Pampeana, con relictos empobrecidos de la colindante Provincia del Espinal e influenciada por la Provincia Paranaense a...

The study area is located in the middle-east of Entre Ríos; fitogeographically, the region is included in the Pampean Province, with relicts of the nearest Espinal Province and influenced by the Paranaese Province through the gallery forest of the streams. Eight field works were carried out (including trapping, owls pellets analysis, observation tr...

The richness, diversity, abundance and prevalence of mite species associated with sigmodontine rodents of different species in Entre Ríos province, Argentina are studied. Five of the six species of mites were reported for the first time in the study area. The richness and diversity of mites was higher on Oligoryzomys flavescens and O. delticola tha...

Se menciona por primera vez a Laelaps manguinhosi Fonseca asociado a Holochilus brasiliensis (Desmarest) (Rodentia: Muridae: Sigmodontinae) en la Argentina. Asimismo, se lo registra por primera vez en las provincias de Corrientes y Entre Ríos.
