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 maintenance of ideal amounts of water and body temperature close to optimal values results in a functional conflict between thermoregulation and water balance, typically with the last being prioritized. Besides presenting high cutaneous resistance for water loss, non-avian reptiles can trigger cooling responses through respiratory evaporative water loss, such as panting and gaping, th…
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 utilization of adenosine triphosphate (ATP) molecules in aerobic eukaryotes is crucial for supporting energy-demanding cellular processes, predominantly facilitated by mitochondrial oxidative phosphorylation. Nutritional balance is vital for ATP generation via cellular respiration, influencing cellular health and complex structure assembly. Infections increase ATP demand for immune ce…
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 …
