Regional variability in diving physiology and behavior in a widely distributed air-breathing marine predator, the South American sea lion (Otaria byronia)
(Company of Biologists Ltd, 2016)
Our understanding of how air-breathing marine predators cope with environmental variability is limited by our inadequate knowledge of their ecological and physiological parameters. Because of their wide distribution along ...
Adaptive Potential of the Heme Oxygenase/Carbon Monoxide Pathway During Hypoxia
(Frontiers Media, 2020)
Heme oxygenase (HO) enzymes catalyze heme into biliverdin, releasing carbon monoxide (CO) and iron into circulation. These byproducts of heme degradation can have potent cytoprotective effects in the face of stressors such ...
DEVELOPMENT OF BLOOD-PRESSURE AND CARDIAC REFLEXES IN THE FROG PSEUDIS-PARADOXSUS
(Amer Physiological Soc, 1992-09-01)
Systemic arterial blood pressure and heart rate (f(H)) were measured in unanesthetized, unrestrained larvae and adults of the paradoxical frog, Pseudis paradoxus from São Paulo State in Brazil. Four developmental groups ...

Uncovering deep mysteries: The underwater life of an amphibious louse
(Elsevier, 2014-11-07)
Despite the incredible success of insects in colonizing almost every habitat, they remain virtually absent in one major environment – the open sea. A variety of hypotheses have been raised to explain why just a few insect ...
Under pressure: the extraordinary survival of seal lice in the deep sea
(Company of Biologists, 2020-09)
Lice from pinnipeds, i.e. sea lions, seals, and walruses, are the only insects capable of surviving marine dives. Along their evolutionary history, they adapted to tolerate hypoxia, high salinity, low temperature and, in ...
