Thermal regime effects on the resting metabolic rate of rattlesnakes depend on temperature range
(Elsevier B.V., 2019-07-01)
While ectothermic organisms often experience considerable circadian variation in body temperature under natural conditions, the study of the effects of temperature on metabolic rates are traditionally based on subjecting ...
Effects of Temperature on Intraspecific Competition in Ectotherms
(Univ Chicago Press, 2014-09-01)
Understanding how temperature influences population regulation through its effects on intraspecific competition is an important question for which there is currently little theory or data. Here we develop a theoretical ...
Incubation and rearing temperature effects on Hsp70 levels and heat stress response in broilers
(Agricultural Inst Canada, 2003-06-01)
Incubation temperature (IT) was changed to evaluate if 6-wk-old birds become more tolerant to heat stress. After 13 d of incubation, 470 eggs were submitted to low (36.8degreesC), normal (37.8degreesC) and high (38.8degreesC) ...
Environmental temperature and cloacal and surface temperatures of broiler chicks in first week post-hatch
(Applied Poultry Science Inc, 2000-03-01)
Adequate environmental temperature during the brooding period is very important to future broiler performance. Thus, the objective of this study was to investigate the extent to which environmental temperature affects the ...
Environmental temperature and cloacal and surface temperatures of broiler chicks in first week post-hatch
(2000-01-01)
Adequate environmental temperature during the brooding period is very important to future broiler performance. Thus, the objective of this study was to investigate the extent to which environmental temperature affects the ...
Quantum state density and critical temperature in M-theory
(World Scientific Publ Co Pte Ltd, 2001-11-20)
We discuss the asymptotic properties of quantum states density for fundamental p-branes which can yield a microscopic interpretation of the thermodynamic quantities in M-theory. The matching of the BPS part of spectrum for ...
A framework for the interpretation of temperature effects on dormancy and germination in seed populations showing dormancy
(Cambridge University Press, 2015-06)
Temperature is a key factor affecting both dormancy and germination. In non-dormant seeds, when temperature is within the thermal range permissive for germination, it just regulates germination velocity, while in seeds ...
Photosynthetic responses to temperature in tropical lotic macroalgae
(2004-06-01)
A comparative analysis of the photosynthetic responses to temperature (10-30°C) was carried out under short-term laboratory conditions by chlorophyll fluorescence and oxygen (O2) evolution. Ten lotic macroalgal species ...
Minimum temperature differences between the meteorological screen and grass in radiative frost nightsDiferenças de temperatura mínima entre o abrigo meteorológico e a relva em noites com geadas
(2018-11-01)
A phenomenon called thermal inversion, in which there is the accumulation of colder and denser air in the layers closer to the soil, occurs in radiative frost nights, resulting in a temperature gradient with differences ...
Effect of breeder age on eggshell thickness, surface temperature, hatchability and chick weigh
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2012-03-01)
Two experiments were carried out to study the effect of breeder age on incubation parameters (hatchability, eggshell thickness, egg surface temperature and chick weight). In Exp. 1, fertile eggs (30- and 60-wk-old breeders) ...
