Water economy in rodents: evaporative water loss and metabolic water production
Provedor de dados: 97
Autores: Cortés,Arturo; Rosenmann,Mario; Bozinovic,Francisco.
Studies on water balance in desert-dwelling granivorous rodents use evaporative water loss (EWL) and metabolic water production (MWP) to evaluate the efficiency of water regulation, expressed by the model Ta @ MWP = EWL, defined by an ambient temperature (Ta) value at (@) which MWP/EWL = 1. Here we evaluate and apply this model (1 - r²) determining water regulation efficiency, based on the energetic cost (MR) to maintain water balance (WB), that is MR-WB. To test the model, EWL was measured and MWP estimated in nine species of rodents from different localities of northern and north-central Chile (II and IV Regions): Octodon degus (Od) and O. lunatus (Olu) (Octodontidae), Abrothrix olivaceus (Ao), A. longipilis (Al), A. andinus (Ad), Phyllotis darwini (Pd),...

A time-energy analysis of daytime surface activity in degus, Octodon degus
Provedor de dados: 97
Autores: Kenagy,G.J.; Vásquez,Rodrigo A.; Nespolo,Roberto F.; Bozinovic,Francisco.
We present an analysis of time and energy allocation in a day-active caviomorph rodent, the degu, Octodon degus, in central Chile. We quantified components of surface activity in the field on a daily basis in individual degus near the time of the summer solstice, when conditions of heat and aridity were also at a seasonal extreme, in order to answer the following questions. Does the absolute time available for surface activity limit performance? Does the allocation of time and energy for locomotion place a functionally significant limitation on overall energy balance and performance? Degus spent about 2/3 of their above-ground time foraging; they remained stationary about 88 % of the time, walked around slowly about 10 %, and were running rapidly from one...

Energetics, thermoregulation and torpor in the Chilean mouse-opossum Thylamys elegans (Didelphidae)
Provedor de dados: 97
Autores: Bozinovic,Francisco; RuÍz,Gricelda; CortÉs,Arturo; Rosenmann,Mario.
In this paper we studied the energetic expenditure and thermoregulation of the Chilean mouse-opossum Thylamys elegans (Dielphidae) a nocturnal small marsupial, endemic of southern South America. We studied their standard energetic and determined whether they exhibit shallow daily torpor or deep prolonged torpor as a function of ambient temperature and food availability. Thylamys elegans partially supports the hypothesis that Neotropical marsupials have somewhat a higher basal metabolic rate (BMR) and thermal conductance (Cm) than Australian ones. In fact, BMR was higher but Cm was lower than expected for their body mass. The higher mass-independent BMR of the Chilean mouse-opossum may be explained by its insectivorous food habits and its low Cm by its...

On cognitive ecology and the environmental factors that promote Alzheimer disease: lessons from Octodon degus (Rodentia: Octodontidae)
Provedor de dados: 48
Autores: Rivera,Daniela S.; Inestrosa,Nibaldo C.; Bozinovic,Francisco.
Cognitive ecologist posits that the more efficiently an animal uses information from the biotic and abiotic environment, the more adaptive are its cognitive abilities. Nevertheless, this approach does not test for natural neurodegenerative processes under field or experimental conditions, which may recover animals information processing and decision making and may explain, mechanistically, maladaptive behaviors. Here, we call for integrative approaches to explain the relationship between ultimate and proximate mechanisms behind social behavior. We highlight the importance of using the endemic caviomorph rodent Octodon degus as a valuable natural model for mechanistic studies of social behavior and to explain how physical environments can shape social...
