Humpback whale (Megaptera novaeangliae) populations worldwide have been recovering from whaling, albeit at different rates. A recent global review of
We update the results of a 20-year (1996-2015) collaborative study examining the abundance and the population structure of these animals
We document the occurrence of mothers and calves in the PCFG area over a more than 20-year period. Over the
We found that PCFG whales often migrated together based on a review of identification photographs of migrating gray whales encountered
Whale watching is often conducted from motorized vessels, which contribute to underwater noise pollution and can disturb marine mammals. Protective
Resource partitioning is an important process driving habitat use and foraging strategies in sympatric species that potentially compete. Differences in
The anatomy of large cetaceans has been well documented, mostly through dissection of dead specimens. However, the difficulty of studying
We address the problem of identifying individual cetaceans from images showing the trailing edge of their fins. Given the trailing
