How to engineer a habitable planet: the rise of marine ecosystem engineers through the Phanerozoic
Palaeontology, Volume 67, Issue 5, September/October 2024.Abstract Ecosystem engineers are organisms that modify their physical habitats in a way that alters resource availability and the structure of the communities they live in. The evolution of ecosystem engineers over the course of Earth history has thus been suggested to have been a driver of macroevolutionary and macroecological changes that are ...
