Trypanosoma cruzi-infected triatomines and rodents co-occur in a coastal island of northern Chile
(Peerj Inc, 2020)
Trypanosoma cruzi, the cause agent of Chagas disease, is transmitted mainly by blood-feeding insects of the subfamily Triatominae. The T. cruzi life cycle alternates between triatomines and mammalian hosts, excluding birds ...
Can social behaviour drive accessory olfactory bulb asymmetries? Sister species of caviomorph rodents as a case in point
(Blackwell Publishing Ltd, 2020)
Physiological flexibility in field urine osmolality of rodents from semi-arid Chile
(University of California, 2007)
Food selection in an herbivorous rodent: Balancing nutrition with thermoregulation
(Ecological Society of America, 1997)
The degu, Octodon degus (Rodentia, Octodontidae) is a diurnal herbivore inhabiting the semiarid and mediterranean environments of northern and central Chile. In the field, degus are constrained to specific foraging areas, ...
Does digestion rate affect diet selection? A study in Octodon degus, a generalist herbivorous rodent
(Springer Verlag, 1998)
Dietary chemistry and an animal digestive physiology should be considered in any explanation of behavioral patterns of food use, as both influence dietary preference. In the degu Octodon degus (Molina, 1782), a generalist ...
Sociality, exotic ectoparasites, and fitness in the plural breeding rodent Octodon degus
(Springer, 2012)
Social animals are susceptible to high infection
levels by contact-transmitted parasites due to increased
conspecific interaction. Exotic parasites are known to have
adverse consequences on native hosts. We examined ...
Assessment of predation risk via illumination level: facultative central place foraging in the cricetid rodent Phyllotis darwini
(Springer-Verlag, 1994)
It is well known that the risk of predation affects prey decision making. However, few studies have been concerned with the cues used by prey to assess this risk. Prey animals may use indirect environmental cues to assess ...
Relatedness does not predict vigilance in a population of the social rodent Octodon degus
(Springer, 2013)
The possibility that social foragers adjust and
coordinate their scanning activity when in the presence of
close relatives to attain inclusive fitness benefits remains
controversial and scarcely examined. To this aim, ...
Validation of a radioimmunoassay for measuring fecal cortisol metabolites in the hystricomorph rodent, octodon degus
(2009)
Determination of fecal steroid metabolites is a noninvasive technique that characterizes the physiological state of organisms without the physiological and psychological stress of handling. Although this technique has many ...
Ecological drivers of group living in two populations of the communally rearing rodent, Octodon degus
(Springer, 2012)
Intraspecific variation in sociality is thought to
reflect a trade-off between current fitness benefits and costs
that emerge from individuals' decision to join or leave
groups. Since those benefits and costs may be ...
