Impact of the #extinct megaherbivore Steller's sea cow (Hydrodamalis gigas) on kelp forest resilience https://www.frontiersin.org/articles/10.3389/fevo.2022.983558/full
One of the more important and surprising findings was that including the Steller's sea cow in the model resulted in a totally different type of #KelpForest. Instead of kelp-dominated... it resulted in more of a balance between #kelp and #algae as more sunlight would have reached the sea floor.
For millions of years, the Steller's sea cow, a four-ton marine mammal and relative of the manatee, shaped kelp forests along the Pacific coast of North America by eating massive quantities of kelp fronds from the upper canopies, thus allowing light to spur productivity in the understory.
