The Sea Around Us principal investigator, Dr. Daniel Pauly, has been granted the 2023 Ecology and Evolution Leader Award by academic platform Research.com.
The award is the result of Dr. Pauly being recognized as Canada’s top scientist in the field of Ecology and Evolution in the platform’s 2023 Ranking of Best Scientists. Globally, the Sea Around Us’ PI ranked #27.
Trilobites- extinct marine arthropods that roamed the world’s oceans from about 520 million years ago until they went extinct 250 million years ago, at the end of the Permian period – may have grown in a similar fashion and reached ages that match those of extant crustaceans, a new study has found.

Despite their odd shape, which makes them resemble a tuft of seaweed, common and leafy seadragons grow in the same fashion as other bony fish, new research has found.
Atlantic cod (Gadus morhua) is among the fish species maturing and spawning earlier in the “spring” reproductive season, due to higher water temperature. Photo by GRID-Arendal, Flickr.
Fisheries managers and researchers may now predict how early fish will spawn in response to warming waters due to climate change, both in the oceans and in freshwaters.

Discounting anthropogenic-induced changes, the seasonally oscillating environments where long-lived fish hatch and grow remain more or less the same throughout the course of their lives. This means that the common explanation that states that fish become sexually active – or spawn for the first time – after experiencing certain environmental stimuli does not properly explain this phenomenon.
