Acute-Phase Immune Response Involves Fever, Sickness Behavior, and an Elevated Metabolic Rate in the Subterranean Rodent Ctenomys talarum [PDF]

, 2022
The acute-phase response (APR) is an induced innate response and may involve pronounced physiological and behavioral changes. One of the most common assays to study the APR involves the use of a lypopolysaccharide (LPS) from the cell wall of gram ...

FUNCTIONAL MORPHOLOGY OF THE MIDDLE EAR OF Ctenomys talarum (RODENTIA: OCTODONTIDAE) [PDF]

Journal of Mammalogy, 2004
The middle ear of the solitary subterranean rodent Ctenomys talarum was studied. The most significant features observed were the enlarged middle-ear cavity, a round and larger eardrum without pars flaccida, no connection between malleus and the tympanic bone, partial fusion of malleus with incus, a nearly flat stapedial footplate, absence of stapedial ...

Seasonality in Reproduction and Reproductive Physiology of Caviomorphs

Mammal Review, Volume 55, Issue 3, July 2025.
ABSTRACT Animals experience seasonal fluctuations of photoperiod, food availability, temperature and precipitation. This affects their energy budget, often leading to seasonal reproduction. We review available literature and (re)‐analyse existing datasets on seasonal reproduction of South American caviomorph rodents that are characterised by long ...

Energetics and thermoregulation during digging in the rodent tuco-tuco (Ctenomys talarum)

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2007
For subterranean rodents, searching for food by extension of the tunnel system and maintenance of body temperature are two of the most important factors affecting their life underground. In this study we assess the effect of ambient temperature on energetics and thermoregulation during digging in Ctenomys talarum.

On the presence of Ctenomys talarum (Rodentia, Ctenomyidae) in northeastern Buenos Aires province, Argentina [PDF]

, 2014
El género Ctenomys se encuentra ampliamente distribuído en Argentina. Su ausencia en el norte de la provincia de Buenos Aires desde el Holoceno tardío, fue considerada como el resultado de cambios climáticos ocurridos en el pasado.

A herbivore tag-and-trace system reveals contact- and density-dependent repellence of a root toxin [PDF]

, 2017
Foraging behavior of root feeding organisms strongly affects plant-environment-interactions and ecosystem processes. However, the impact of plant chemistry on root herbivore movement in the soil is poorly understood.

Does hypometabolism constrain innate immune defense?

Acta Physiologica, Volume 240, Issue 3, March 2024.
Abstract Many animals routinely make energetic trade‐offs to adjust to environmental demands and these trade‐offs often have significant implications for survival. For example, environmental hypoxia is commonly experienced by many organisms and is an energetically challenging condition because reduced oxygen availability constrains aerobic energy ...

Topographic barriers drive the pronounced genetic subdivision of a range‐limited fossorial rodent

Molecular Ecology, Volume 33, Issue 5, March 2024.
Abstract Due to their limited dispersal ability, fossorial species with predominantly belowground activity usually show increased levels of population subdivision across relatively small spatial scales. This may be exacerbated in harsh mountain ecosystems, where landscape geomorphology limits species' dispersal ability and leads to small effective ...

Immune-challenged fish up-regulate their metabolic scope to support locomotion [PDF]

, 2016
ArticleEnergy-based trade-offs occur when investment in one fitness-related trait diverts energy away from other traits. The extent to which such trade-offs are shaped by limits on the rate of conversion of energy ingested in food (e.g.
