Effects of parasitism on antipredatory responses and defensive behaviors in the subterranean rodent Ctenomys talarum
(National Research Council Canada-NRC Research Press, 2022-02)
La prédation constitue un important facteur d’évolution modulant différentes adaptations. Les organismes proies présentent des adaptations comportementales qui leur permettent de reconnaître, éviter et se défendre contre ...
Copulatory pattern of the subterranean rodent Ctenomys talarum
(De Gruyter, 2008)
Food Restriction Affects Inflammatory Response and Nutritional State in Tuco-tucos (Ctenomys talarum)
(Wiley-liss, Div John Wiley & Sons Inc, 2016-12)
Insufficient or unbalanced food intake typically has a negative impact on immune responses. The understanding of this effect is, however, hampered by the effect that food has on general condition, which, in turn, affects ...
Parasite infection negatively affects PHA-triggered inflammation in the subterranean rodent Ctenomys talarum
(Wiley-liss, Div John Wiley & Sons Inc, 2016-02)
Magnitude and effectiveness of immune responses vary greatly between and within species. Among factors reported to determine this variation, parasitism is a critical one, although controversial effects of parasites over ...
Cortisol and corticosterone exhibit different seasonal variation and responses to acute stress and captivity in tuco-tucos (Ctenomys talarum)
(Academic Press Inc Elsevier Science, 2011-02)
In this work we aimed to evaluate variations in plasma glucocorticoids (GCs, cortisol and corticosterone) levels throughout an annual cycle in free-living male tuco-tucos (Ctenomys talarum) and compare their responses to ...
Selective binocular vision loss in two subterranean caviomorph rodents: Spalacopus cyanus and Ctenomys talarum
(Nature, 2017-02)
To what extent can the mammalian visual system be shaped by visual behavior? Here we analyze the shape of the visual fields, the densities and distribution of cells in the retinal ganglion-cell layer and the organization ...
Respuestas antipredatorias y comportamientos defensivos frente a señales indicativas de la presencia de un predador en el roedor subterráneo Ctenomys talarum
(2018-03-27)
La predación representa una importante fuerza evolutiva modelando adaptaciones específicas que permiten a los organismos presa reconocer, evitar y defenderse de los predadores. Más allá de los efectos letales de la predación, ...

Cost of foraging in the subterranean rodent Ctenomys talarum: effect of soil hardness
(National Research Council Canada-NRC Research Press, 2006-05-26)
Subterranean burrows provide inhabitants with shelter, a relatively stable thermal environment, and potentially access to food resources. However, one cost of living in such burrows is the energetically expensive mode of ...
Home-Range and Activity Patterns of the South American Subterranean Rodent Ctenomys talarum
(Alliance Communications Group Division Allen Press, 2006-12-29)
Subterranean rodents are characterized by limited individual mobility and patchy distribution of local populations, all of which have been related to the great evolutionary diversification of this group. Because of their ...
