For example, although small krill are individually only about one millionth of the weight of a large tuna, they also tend to be a million times more numerous throughout the oceans. The idea, known as the Sheldon size spectrum theory, was first advanced in the 1970s, but has never been tested for a wide range of marine species and on a global scale until now.</p> Wed, 10 Nov 2021 20:46:52 +0000 katherine.gombay@mcgill.ca 283616 at /newsroom
