Trading heat and hops for water: Dehydration effects on locomotor performance, thermal limits, and thermoregulatory behavior of a terrestrial toad
(Wiley-Blackwell, 2017-11-01)
Due to their highly permeable skin and ectothermy, terrestrial amphibians are challenged by compromises between water balance and body temperature regulation. The way in which such compromises are accommodated, under a ...
Neither altered incubation temperature during fetal development nor preferred rearing temperature improves leg bone characteristics of broilers
(2020-10-01)
The present study evaluated whether broiler femoral and tibiotarsal characteristics (as assessed at slaughter age) could be improved if birds were reared under their preferred temperature and whether continuous high or low ...
Feeding alters the preferred body temperature of Cururu toads, Rhinella diptycha (Anura, Bufonidae)
(Elsevier B.V., 2020-11-01)
Ectothermic organisms depend primarily on external heat sources and behavioural adjustments to regulate body temperature. Under controlled conditions, in a thermal gradient, body temperature often clusters around a more ...
Role of central nitric oxide in behavioral thermoregulation of toads during hypoxia
(Pergamon-Elsevier B.V. Ltd, 2008-09-03)
Nitric oxide (NO) is thought to play a key role in the development of hypoxia-induced anapyrexia in mammals, acting on the preoptic region of the anterior hypothalamus to activate autonomic heat loss responses. Regarding ...
Interplay between behavioural thermoregulation and immune response in mealworms
(2012)
Since the preferential body temperature should positively correlate with physiological performance, behavioural fever should enhance an organism's immune response under an immune challenge. Here we have studied the ...
Hypoxia during embryonic development increases energy metabolism in normoxic juvenile chicks
(Elsevier B.V., 2017-05-01)
Environmental changes during perinatal development can affect the postnatal life. In this sense, chicken embryos that experience low levels of O-2 over a specific phase of incubation can have their tissue growth reduced ...
Thermal biology of the toad Rhinella schneideri in a seminatural environment in southeastern Brazil
(2015-10-02)
The toad, Rhinella schneideri, is a large-bodied anuran amphibian with a broad distribution over South America. R. schneideri is known to be active at night during the warm/rainy months and goes into estivation during the ...
Seasonal variation in the thermal biology of a terrestrial toad, Rhinella icterica (Bufonidae), from the Brazilian Atlantic Forest
(2018-05-01)
As ectotherms, amphibians may exhibit changes in their thermal biology associated with spatial and temporal environmental contingencies. However, our knowledge on how amphibian´s thermal biology responds to seasonal changes ...
Short-term predicted extinction of Andean populations of the lizard Stenocercus guentheri (Iguanidae: Tropidurinae)
(PUCE, 2015)
We studied the thermal physiology of the Andean lizard Stenocercus guentheri in
order to evaluate the possible effects of global warming on this species. We determined the
preferred body temperature (Tpref), critical ...
Effect of temperature on the visual displays of the Jacky dragon
(2019)
In ectotherms such as lizards, temperature is a key determinant of their behavior and their ability to signal to conspecifics. We asked whether changes in the thermal environment along the distribution of an agamid lizard, ...
