Basal rate of metabolism and temperature regulation of two desert herbivorous octodontid rodents: Octomys mimax and Tympanoctomys barrerae
(Springer-Verlag, 1990)
We studied the energetics of two herbivorous desert rodents from South America. The two species had slightly lower basal metabolic rates, lower thermal conductances, and higher temperature differentials than those expected ...
Effect of gestational and postnatal environmental temperature on metabolic rate in the altricial rodent, Phyllotis darwini
(2009)
1.In the altricial rodent, Phyllotis darwini, we found higher body temperatures and faster developmental rates of the thermoregulatory capacity in neonates born from cold- than warm-acclimated mothers.2.This difference ...
Phylogenetic and ecological factors affecting the sharing of helminths between native and introduced rodents in Central Chile
(Cambridge University Press, 2018)
Copyright © Cambridge University Press 2018. In order to analyse the effect of hosts' relationships and the helminthic load on the switching of parasites between native and introduced hosts, we sampled rodents belonging ...
Anatomy of reproductive tract in octodon degus molina: A nonscrotal rodent
(Informa Healthcare, 1980)
O. degusreproductive tract is characterized externally by a perianal circle with the penis pointing posteriorly. Beneath the perianal circle is the cremasteric sac. Testes are always inside the abdomen, with the epididymis ...
Biology of hantavirus reservoir rodents in Chile Biología de roedores reservorios de hantavirus en Chile
(2000)
The basic biology of the potential hantavirus reservoir rodents from Chile are reviewed. The taxonomy and systematics of five endemic Muridae species, the oryzomine Oligoryzomys longicaudatus (probably the primary reservoir), ...
Pollen analyses from a 50 000-yr rodent midden series in the southern Atacama Desert (25° 30′ S)
(John Wiley and Sons Ltd, 2005)
Precipitation in northern Chile is controlled by two great wind belts - the southern westerlies over the southern Atacama and points south (> 24° S) and the tropical easterlies over the northern and central Atacama ...
Rodent middens, a new method for Quaternary research in arid zones of South America Paleomadrigueras de roedores, un nuevo método para el estudio del Cuaternario en zonas áridas de Sudamérica
(2002)
In arid and semi-arid regions of South America, historical evidence for climate and vegetation change is scarce despite its importance for determining reference conditions and rates of natural variability in areas susceptible ...
Effects of environmental temperature on oxygen diffusion capacity during post-natal development in the altricial rodent, Phyllotis darwini
(Sociedad de Biologia de Chile, 2009)
In this contribution we studied the developmental phenotypic plasticity of respiratory structures involved in the exchange of gases in an altricial rodent, the leaf-eared mouse (Phyllotis darwini). We studied morphological ...
Thermal biology of the fossorial rodent Ctenomys fulvus from the Atacama desert, northern Chile
(2000)
The Andean tuco-tuco, Ctenomys fulvus (Rodentia: Ctenomyidae) inhabits one of the most arid regions of the world, the Salar de Atacama, Northeast of Antofagasta, Chile (23°17'06''S, 68°05'43''W; 2.240 m.a.s.l). We found ...
Thermoregulatory constraints on the microhabitat use by cricetid rodents in central chile
(1992)
The energetic cost of thermoregulation related to microhabitat use by nocturnal rodents is studied in four rodent species from central Chile. Rodents concentrate their activity under shrub canopies, avoiding open areas. ...
