Development of aerobic and anaerobic metabolism in cardiac and skeletal muscles from harp and hooded seals.
In diving animals, skeletal muscle adaptations to extend underwater time despite selective vasoconstriction include elevated myoglobin (Mb) concentrations, high acid buffering ability (beta) and high aerobic and anaerobic enzyme activities. However, because cardiac muscle is perfused during dives, it may rely less heavily on Mb, beta and anaerobic pathways to support contractile activity. In ad...
متن کاملGiardia and Cryptosporidium in harp and hooded seals from the Gulf of St. Lawrence, Canada.

متن کاملThe Effects of Climate Change on Harp Seals (Pagophilus groenlandicus)
Harp seals (Pagophilus groenlandicus) have evolved life history strategies to exploit seasonal sea ice as a breeding platform. As such, individuals are prepared to deal with fluctuations in the quantity and quality of ice in their breeding areas. It remains unclear, however, how shifts in climate may affect seal populations. The present study assesses the effects of climate change on harp seals...
