I love Mexico's Kelp forests, because in them, there is an amazing community of fishers, NGOs, academics, & people. They are tough but kind, threatened but resilient. Just like the Baja California dessert, a magic underwater forest exists where collaboration is key for adaptation. Thank you again!

Join the Global Coalition to Halt Shark and Ray Extinction
Over 35% of sharks and rays are threatened with extinction — most are declining due to overfishing. Urgent, coordinated action is needed.

This was one of my students’ favorite posts of the week
Exploring 8 nursing sites of red-spotted catsharks in and amongst Chile's kelp forests, Ítalo Fernández found that females showed a greater preference for anchoring eggs to kelp with larger holdfasts, more stipes and greater total length.

Because size matters: what we have learned about shark nesting sites
My biggest concern in this project is to understand how changes in the size structure of kelp forests could affect the use of kelp as a nesting substrate for elasmobranch species in Chile. Therefore, ...

Marine heat wave confirmed cause of death for 4 million birds (Common Murres) in 2016. Half of Alaska’s Common Murre population at the time. Largest documented animal die-off in modern history.
