Paul K. Dayton

Paul K. Dayton is an influential American marine ecologist renowned for his foundational research on kelp forest ecosystems and benthic community dynamics. His long-term experimental work, primarily conducted at sites like the Point Loma kelp forests in Southern California, has profoundly shaped understanding of ecological succession, predation, and disturbance (ecology) in marine environments. A professor emeritus at the Scripps Institution of Oceanography (part of the University of California, San Diego), his career is distinguished by a commitment to rigorous field experimentation and the application of ecological science to marine conservation and environmental policy.

Early life and education

His academic journey began at the University of Washington, where he completed his undergraduate studies. He then pursued a Ph.D. in biological oceanography at Stanford University, working at the university's renowned Hopkins Marine Station in Pacific Grove, California. His doctoral research, advised by prominent ecologists, focused on the intertidal communities of the Pacific Northwest, laying the groundwork for his lifelong interest in community ecology and species interactions. This formative period immersed him in the influential scientific traditions of Robert T. Paine, known for keystone species, and other pioneers of experimental marine ecology.

Career and research

Upon joining the faculty at the Scripps Institution of Oceanography, he established a pioneering research program centered on the kelp forest ecosystems off San Diego. His innovative, long-term field experiments, often involving the manual removal of key species like sea urchins or predatory fishes, provided unprecedented insights into trophic cascades and the maintenance of biodiversity. His work demonstrated the critical role of sea otters and lobsters in controlling herbivore populations and preventing urchin barrens. He also conducted seminal work in Antarctica, studying the benthic communities of McMurdo Sound and their vulnerability to climate change and iceberg scouring. His research has been instrumental in informing the management of marine protected areas, including efforts related to the Channel Islands National Marine Sanctuary.

Awards and honors

His contributions to ecological science have been recognized with several of the field's most prestigious awards. He is a recipient of the George Mercer Award from the Ecological Society of America, honoring an outstanding published ecological research paper. The same society later awarded him its Eminent Ecologist Award for sustained contributions to the science of ecology. He is an elected Fellow of the American Association for the Advancement of Science and the California Academy of Sciences. His work has also been honored by the Western Society of Naturalists and the Benthic Ecology Meeting.

Selected publications

His influential body of work includes landmark papers and books that are standard references in marine ecology. Key publications often co-authored with colleagues like Mia J. Tegner and Susan L. Williams, include "Ecology of Kelp Communities" in the Annual Review of Ecology and Systematics and "Sliding Baselines, Ghosts, and Reduced Expectations in Kelp Forest Communities" in Ecological Applications. His research on Antarctic benthos has been published in journals such as Ecological Monographs and Science. The book Marine Community Ecology, co-edited with Mark Bertness and Steven D. Gaines, is a widely used textbook.

Personal life

Residing in San Diego, California, he is known among colleagues and students for a passionate, hands-on approach to field ecology and a steadfast advocacy for evidence-based conservation. An avid outdoorsman, his personal interests are deeply connected to the coastal and marine environments he has studied throughout his career. He has mentored numerous graduate students and postdoctoral researchers who have gone on to prominent positions at institutions like the University of California, Santa Barbara, the National Oceanic and Atmospheric Administration, and various University of California campuses.
