Temperature and availability of water and food profoundly affect the physiology, behavior and ecology of animals, especially ectotherms. Climate variability exposes them to considerable changes in the thermal, water and food configuration of the environment at both geographic and temporal scales. Thus, the successful occupation and maintenance of viable populations in different habitats o…
Heat exposure in the first week of life in precocious birds has been shown to be a more intense stress than exposure to cold. Furthermore, it is known that dehydration inhibits evaporative heat loss responses leading to hyperthermia, and that immunological challenge, depending on the intensity of the stimulus, leads to fever (increased metabolic demand) or regulated hypothermia (conservat…
The present project aims to investigate the role of brain serotonin and its precursor tryptophan in the regulation of the activity of cold (thermogenesis and peripheral vasoconstriction) and heat (peripheral vasodilatation and thermal tachypnea) thermoeffectors in broiler chicks in the first week of post-hatching life. To this end, body temperature, oxygen consumption (thermogenesis), pul…
During severe sepsis and associated systemic inflammatory responses, there may be a drop in body temperature (Tc) rather than fever. Formerly considered as an unregulated response of the organism, this fall of Tc has been interpreted today in mammals as a regulated, transitory and beneficial event. Although it has already been described in birds, there is no evidence that this thermal res…
The thermo-TRPV4 channels are expressed in various tissues, including peripheral sensors in birds and peripheral and central sites in mammals. In rats, we have demonstrated that peripheral TRPV4 (possibly skin) appear active in a range of ambient temperature (Ta) higher than 22 ° C and lower than 32 ° C, being involved in activation of heat loss responses, both autonomic (tail vasodilatio…

The comparison of physiological and behavioral cycles between semi-natural conditions in the laboratory with those occurring in the wild, without shelter and food, may indicate whether there are biases related to the interference of captivity in the phenology of a species, and in the seasonal cycles. In this context, ecological conflicts are more pressing in the natural world than in the …
Water availability, along with temperature and food availability, are critical factors that significantly affect animal physiology, fitness and survival. These environmental factors constitute selective pressures that act within the limits of the animals' capacities and tolerance, including varying degrees of phenotypic flexibility. Based on these organism-environment interactions, season…

The tegu lizard Salvator merianae is widely distributed in South America and stands out for presenting endothermia during the reproductive phase (ER) in the spring. This ER is characterized by an increase in body emperature in relation to the ambient temperature concomitant with increased heart rate, but this thermogenic source is not yet described. Mitochondrial respiration and decouplin…

Birds are frequently exposed to pollutants in the form of polycyclic aromatic hydrocarbons (PAHs), including dioxins, which may be unintentionally produced by chemical reactions and combustion and cannot often be controlled. Birds exposed to dioxin, mainly during developmental phase, show many physiological changes including affecting mechanisms involved in energy metabolism and immunity.…
Sleep-disordered breathing (SDB) is more prevalent in adult men than in women and its occurrence increases after menopause, in line with several studies establishing that progesterone is a potent respiratory stimulant, that reduces the frequency of apnea in postmenopausal women. It is know that progesterone is synthetized in the ovaries of adult females, but also in the central and periph…
We will investigate the influence of hypoxia during incubation on the O2 and CO2 chemosensitivity of one-day Leghorn® chicks. Fertile eggs will be incubated in three different conditions: normoxia (21% O2) during all the incubation; hypoxia (15% O2) during the entire last day of incubation; and hypoxia for 2 hours a day during all the incubation. Pulmonary ventilation, oxygen consumption …
