Hormones display broad effects in different aspects of vertebrates' phenotypes, physiologically mediating transitions between life-history phases. Vertebrates that display seasonal reproduction or go through marked changes during development, for example, show clear and well-marked variations in hormone levels. Although endocrine mediation of metamorphosis has been well investigated, less…
In recent decades, there has been a steep decline in amphibian populations around the globe. This decline is associated with multiple causes acting in a synergistic way, highlighting the increase in the prevalence and outbreaks of emerging diseases, the loss, fragmentation and disconnection of habitats, environmental pollution and climate change in multiple scales. In this context of expo…
An unequivocal pattern that involves both natural and anthropic causes, is the global, yet heterogeneous, change in the climate of Earth. This trend, paralleled by other anthropic environmental changes, is expected to cause pervasive effects on the fauna. However, the nature, span and final consequences of climate change must differ among taxa, even among related species, because of the v…

Anthropogenic climate changes are leading to an increase in the global mean temperature and a higher incidence of extreme climate events, impairing the physiology of animals, with highlights for their effects on the immunity, given that these conditions act as stressors capable of interfering with the corticosterone (CORT) secretion and the leukocytes profile. Furthermore, the repetitive …
Melatonin produced by the pineal gland, in addition to being the hormone that signals the dark phase of the day, also regulates immune and pre-immune defense. There is evidence that in anurans, like mammals, the daily melatonin rhythm could also interfere with defense processes. This project aims to describe a possible immune-pineal-(ocular?) axis in anurans and to investigate whether an …
Persistent anthropogenic disturbances such as those resulting from urbanization, habitat degradation and ecotourism are of substantial concern, once chronically stressful conditions can be pathological and negatively affect individual fitness. Long-lived vertebrates that occupy high trophic levels in the food chain, such as sharks, are ideal models for integrated studies of physiological …

The hypothalamic-pituitary-adrenal/interrenal (HPA/I) axis secretes glucocorticoids (GC) in a circadian manner, steroid hormones that are essential for signaling the activity period and regulating metabolic, immune, behavioral, and other functions. In many animals, a seasonal elevation of GC during the reproductive season is observed, which appears to be linked to meeting the high costs a…
Amphibians are currently the most endangered group of vertebrates due to, among many other factors, pandemics caused by fungi, viruses and bacteria. Among the targets of recent immunological studies in vertebrates, the liver stands out as a complex immune organ and primarily responsible for the synthesis of inflammatory proteins, such as acute phase proteins (e.g., C-reactive protein - CR…
The immune system of amphibians is very similar to that of mammals and other vertebrates, presenting surveillance functions and elimination of possible pathogens, besides being modulated in response to stressors. Despite a growing knowledge about immunomodulation associated with stress response in amphibians, the mechanisms associated with specific components of the immune system modulate…

Biological invasions can unfold a new layer of complexity when parasites are introduced along with their hosts. Cane toads (Rhinella marina) are native to Central and South America but were introduced in Australia as an attempt to control crop pests. However, the situation got out of control. The invasive cane toads have been expanding westward, carrying along the South American lungworm …
One of the most frequent environmental consequences of current climate change are high temperatures and droughts in several regions of the world. Europe and specifically the Iberian Peninsula is one of the regions that are being severely affected by these extreme climatic events. In this context, anurans are the group of vertebrates that have been most affected, because, in order to repro…
Sei whales (Balaenoptera borealis) are one of the least studied species of whales; the combination of elusive behavior, broad home range, and deep-water preferences preclude systematic study for most populations. So far, no studies have been regularly conducted on this species, and its physiological and life history parameters remain obscure. A novel way to circumvent the afore mentioned …
