[MARMAM] New publication: Can dolphins decide to reduce their heart rate?

Dear MarMamers My coauthors and I would like to share our new publication on conditioned heart rate responses in dolphins (https://www.frontiersin.org/articles/10.3389/fphys.2020.604018/abstract). In this study we show that the change in heart rate during diving varies depending on

[MARMAM] Heart function in cetaceans

Dear MARMAM community, We would like to share our new publication on cardiac function and cardiorespiratory coupling in cetaceans. In this study, the function of the heart was investigated in the bottlenose dolphin, the beluga, the killer whale, the false killer whale, and the pilot whale. The

[MARMAM] Blood and tissue gas solubility alters lung volume during diving

Dear All We are happy to share our new paper that details how differences in blood and tissue gas solubility of oxygen, carbon dioxide and nitrogen results in changes in mass-balance and ung volume during diving. The reference, url and abstract are below and anyone wanting a pdf copy of the

[MARMAM] Comparative respiratory physiology in cetaceans

Dear All We are happy to share our new publication looking at lung function in a number of cetaceans. We investigated lung function in 2 false killer whales and a juvenile beluga and compared these against previously published data. These data provide comparative estimates for tidal volume,

[MARMAM] Spirometry in dolphins, a conservation tool to help wild cetaceans

Dear All We are happy to share our new publication looking at lung function/spirometry as a diagnostic tool to assess lung health in bottlenose dolphins. We evaluated lung health in 3 bottlenose dolphins under human care to assess whether pulmonary function testing (or spirometry) provide

[MARMAM] Lung function and metabolism in California sea lions

Dear All We are happy to share our new publication looking at lung function and metabolic rate while at rest on land and in water for California sea lions. We investigated how sea lions vary respiratory flow and breath duration on land and in water to keep tidal volume constant. It also
