Rhodolith beds are major CaCO₃ bio-factories in the tropical south west Atlantic
Rhodoliths are nodules of non-geniculate coralline algae that occur in shallow waters (<150 m depth) subjected to episodic disturbance. Rhodolith beds stand with kelp beds,...- publication PDF

Managing climate risks in California: The need to engage resource managers...
In this paper we propose a framework for evaluating how prepared California resource managers are for risks of continued climate change. The framework presented suggests three...- publication PDF
