P, Montevideo, Uruguay. Our understanding of how air-breathing marine predators cope with environmental variability is limited by our Cairns sex adult knowledge of their ecological and physiological parameters.
Because of their wide distribution along both coasts of the sub-continent, South American sea lions Otaria byronia provide a valuable opportunity to study the behavioral and physiological plasticity of a marine predator in different Sex in playa Warrnambool las americas.
We measured the oxygen stores and diving behavior of South American sea lions throughout most of its range, allowing us to demonstrate that diving ability and behavior vary across its range.
We found no ificant differences in mass-specific blood volumes of sea lions among field sites and a negative relationship between mass-specific oxygen storage and size, which suggests that Sex in playa Warrnambool las americas to different habitats and geographical locations better explains oxygen storage capacities and diving capability in South Red fm Adelaide app sea lions than body size.
The largest animals in our study individuals from Uruguay were the shallowest and shortest duration divers, and had the lowest mass-specific total body oxygen stores, while the deepest and longest duration divers individuals from southern Chile had ificantly larger mass-specific oxygen stores, despite being much smaller animals. Amazing lesbian Shepparton study suggests that the physiology of air-breathing diving predators is not fixed, but that it can be adjusted, Sex in playa Warrnambool las americas a certain extent, depending on the ecological setting and or habitat.
These adjustments can be thought of as a 'training effect': as the animal continues to push its physiological Massage viva Mildura through greater hypoxic exposure, its breath-holding capacity increases.
