A South American Mouse Morbillivirus Provides Insight into a Clade of Rodent-Borne Morbilliviruses
(MDPI, 2022-10-29)Morbilliviruses are negative-sense single-stranded monosegmented RNA viruses in the family Paramyxoviridae (order Mononegavirales). Morbilliviruses infect diverse mammals including humans, dogs, cats, small ruminants, ... -
Agriculture in semiarid ecosystems favors the increase fossorial rodent’s activity in La Pampa, Argentina
(Springer, 2019-05-16)Technological advancements and new production systems modify the conditions of natural environments. Transformations in an arid landscape caused by alfalfa cropping under pressurized irrigation systems have generated a ... -
Behavioral responses of two small-sized rodents, Phyllotis vaccarum and Abrothrix andina, to energy challenges of high-altitude habitats in the Andes Mountains
(Wiley, 2022-12)In mountain environments, both temperature and food availability vary strongly with altitude, leading to a major challenge to the thermo-energetic balance of organisms. In this sense, the behavioral repertoire is crucial ... -
Detection of Neorickettsia sp. in Oligoryzomys flavescens rodent from a protected urban area in Buenos Aires City (Argentina)
(Elsevier, 2022-07)Rodents play an important role in vector-borne pathogens cycle. To detect Anaplasma, Ehrlichia, Neorickettsia, Rickettsia and Borrelia species in rodents from a protected urban area in Buenos Aires City (Argentina) were ... -
Developmental environment influences activity levels in a montane rodent, Phyllotis xanthopygus
(Elsevier, 2020-10)Ambient temperature and thermal variability play a crucial role in diverse aspects of organisms’ biology. In the current context of climate change, it is critical to understand how temperature impacts traits that could ... -
Ecology of the interaction between Ixodes loricatus (Acari: Ixodidae) and Akodon azarae (Rodentia: Criceridae)
(2015-10)The present study explores associations of different factors (i.e. host parameters, presence of other ectoparasites and [mainly biotic] environmental factors) with burdens of Ixodes loricatus immature stages in one of its ... -
Ectoparasites associated with rodents (Rodentia) and marsupials (Didelphimorphia) from northeastern Argentina: new host and locality records
(Universidad Nacional Autónoma de México (UNAM), 2020)Taxonomically, ectoparasites represent a very diverse group, which includes: fleas, lice, mites, and ticks, among others. The aim of this work is to extend the knowledge about the ectoparasite fauna associated with rodents ... -
Factors affecting patterns of Amblyomma triste (Acari: Ixodidae) parasitism in a rodent host
(2015-07-30)Here we offer a multivariable analysis that explores associations of different factors (i.e., environmental, host parameters, presence of other ectoparasites) with the interaction of Amblyomma triste immature stages and ... -
Fluoxetine potentiation of Omega-3 fatty acid antidepressant effect: evaluating pharmacokinetic and brain fatty acid-related aspects in rodents
(2014-10)We previously reported that combined fluoxetine administration at antidepressant doses renders additive antidepressant effects, whereas non-antidepressant doses potentiate the omega-3 fatty acid antidepressant effect. In ... -
Food habits of Oligoryzomys longicaudatus (Rodentia) in a steppe–forest transitional area of Argentinean Patagonia
(Asociación Argentina de Ecología, 2014)We described the spatial and seasonal variation of feeding habits of Oligoryzomys longicaudatus in four environments of the steppe-forest transition zone of Argentinean Patagonia. Composition of fecal pellets collected ... -
Garrapatas (ixodida) y ácaros (mesostigmata) parásitos de roedores sigmodontinos del delta del Paraná, Argentina
(2013)Se determinaron las especies de garrapatas y ácaros mesostigmata parásitos de roedores sig-modontinos en una localidad del Delta del Paraná. Fueron registradas 38 asociaciones parásito-hospedador entre dos especies de ... -
Molecular detection and phylogenetic analysis of Hepatozoon spp. in questing Ixodes ricinus ticks and rodents from Slovakia and Czech Republic
(2016-10)By amplification and sequencing of 18S rRNA gene fragments, Hepatozoon spp. DNA was detected in 0.08 % (4/5057) and 0.04 % (1/2473) of questing Ixodes ricinus ticks from Slovakia and Czech Republic, respectively. Hepatozoon ... -
New host species for Leptospira borgpetersenii and Leptospira interrogans serovar Copenhageni
(Elsevier, 2018)We investigated the presence of infection by Leptospira spp. in an assembly of Sigmodontinae rodents from the Paraná Delta, Argentina. Rodents were captured in places with natural grassland, implanted forest, with and ... -
Phenotypic plasticity in the energy metabolism of a small Andean rodent: Effect of short-term thermal acclimation and developmental conditions
(Wiley, 2021-12)The study of phenotypic variation within species in response to different environments is a central issue in evolutionary and ecological physiology. Particularly, ambient temperature is one of the most important factors ... -
Population genetic structure and historical dispersal patterns in the subterranean rodent Ctenomys “chasiquensis” from the southeastern Pampas region, Argentina
(Elsevier, 2016-05)Gene flow plays an essential role in the evolutionary history of the organisms and helps to identify those historical landscape features that most likely had affected the dispersal patterns. In this work, we assess, using ... -
Roedores, bovinos y matemáticas
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-08)Un modelo estadístico que desarrolló y validó el INTA para estudiar la calidad de las vacunas bovinas será utilizado como control oficial por el SENASA. Podría ser recomendado para su implementación en el resto de América -
Spatio-temporal variability in the feeding strategy of Andean rodents: the role of ambient temperature and food availability
(Springer, 2023-05)Animals' diets reflect the morpho-physiological and behavioral responses used to obtain nutrients and energy. While optimal foraging theory predicts them in terms of food availability, the obligatory heat model (OHM) ...
