A Jurassic mammal from South America
(Nature Publishing Group, 2002-03)
The Jurassic period is an important stage in early mammalian evolution, as it saw the first diversification of this group, leading to the stem lineages of monotremes and modern therian mammals. However, the fossil record ...
Assessing mammal responses to perturbations in temperate aridlands of Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2003-12)
Loss of species richness and reduced abundance have been the main responses to perturbations of small- and medium-sized mammals in arid and semi-arid areas. Nonetheless, some mammal species whose habitat requirements are ...
Discovery of a new genus record for Paraguay, the Atlantic Forest endemic rodent Abrawayaomys (Cricetidae, Sigmodontinae)
(De Gruyter, 2020-07)
The mammals of Paraguay are still poorly known. We report a new genus for the country, Abrawayaomys, a spiny cricetid rodent endemic for the Interior Atlantic Forest. This record extends the distribution of the genus ...
Small mammal remains recovered from two archaeological sites in the middle and lower Negro River valley (Late Holocene, Argentina). Taphonomic issues and paleoenvironmental implications
(Pergamon-Elsevier Science Ltd, 2011-01)
This paper presents the results of a taphonomic and paleoenvironmental analysis of small mammal remains recovered from the Negro Muerto and Angostura 1 archaeological sites. These sites (ca. 0.5 and 0.95 ka BP, respectively), ...
Assessment of the role of small mammals in the transmission cycle of tegumentary leishmaniasis and first report of natural infection with Leishmania braziliensis in two sigmodontines in northeastern Argentina
(Springer, 2018-02)
To contribute to the knowledge of the role of small mammals in the transmission cycle of tegumentary leishmaniasis caused by Leishmania braziliensis, we studied the small mammal community and its temporal and spatial ...
Cranial characters associated with the proboscis postnatal-development in Tapirus (Perissodactyla: Tapiridae) and comparisons with other extant and fossil hoofed mammals
(Elsevier Gmbh, 2018-11)
Among extant hoofed mammals, only elephants and tapirs exhibit a true proboscis. We investigated the development of cranial characters potentially associated with the presence of a short proboscis in tapir species, following ...
Hearing loss genes reveal patterns of adaptive evolution at the coding and non-coding levels in mammals
(BioMed Central, 2021-11)
Mammals possess unique hearing capacities that differ significantly from those of the rest of the amniotes. In order to gain insights into the evolution of the mammalian inner ear, we aim to identify the set of genetic ...
Spatial and temporal organisation of small mammal communities in the Monte desert, Argentina
(De Gruyter, 2004-07)
The coexistence of desert small mammals can be explained by differences in microhabitat use, morphology, body size, diet and foraging. The aim of this study was to quantify the structure of small mammal assemblages and the ...
