Adaptation of the andean toad rhinella spinulosa (Anura: Bufonidae) at low temperatures: The role of glucose as cryoprotectant
(University of Chicago Press, 2019-06)
We studied the role of plasma glucose concentration, on individuals of R. spinulosa, in response to the annual temperature variation and freezing temperatures. Measurements and the collection of toads were made every two ...
Calculo de temperatura no silicio irradiado no reator IEA-R1

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 ...
Environmental temperature affects the dynamics of ingestion in the nectivorous ant Camponotus mus
(Elsevier, 2014-10)
Environmental temperature influences physiology and behavior in animals in general and is particularly determinant in ectotherms. Not least because temperature defines metabolism and body temperature, muscle activity in ...
Growing seasons in Chile: Observation and prediction
(1979)
Temperature data for 42 Chilean locations were analysed and heat sums calculated (for base 5 C and 10 C). Also, the length, starting and ending dates of the growing seasons were obtained. Temperature values normally found ...
Do lower air or water temperatures limit the southern distribution of the white mangrove Laguncularia racemosa in South America?
(2019-12-15)
Rising temperatures due to climate change are expected to drive shifts in species composition, phenological patterns and the productivity of mangrove trees. During early life history stages, such as dispersal and settlement, ...
Air velocity and exposure time to ventilation affect body surface and rectal temperature of broiler chickens
(Applied Poultry Science Inc, 2000-03-01)
Increasing air movement over poultry by using fans (ventilation) has become an accepted means of reducing environmental heat stress over the last several years. The purpose of this study was to evaluate the effect of air ...
