  • 1968 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

Theodore J. Smayda was a researcher affiliated with the University of Rhode Island in the United States. Their work primarily focused on fields within Earth and Planetary Sciences and Environmental Science. More specifically, their subfields of study included Paleontology, Oceanography, and Global and Planetary Change.

Their research contributions covered topics related to Marine Invertebrate Physiology and Ecology, Marine and Environmental Studies, and Marine Ecology and Invasive Species. This thematic focus is reflected in their publications and collaborative efforts.

One notable paper authored during their career was titled "Multi-decadal (1972-2019) Mnemiopsis leidyi (Ctenophora) abundance patterns in Narragansett Bay, Rhode Island, USA." Published in 2020 in the Journal of Plankton Research, this study tracked long-term abundance patterns of the invasive comb jelly species in a specific marine ecosystem.

Throughout their career, Theodore J. Smayda frequently collaborated with other researchers. Regular coauthors included Emily Slesinger, Joseph A. Langan, Barbara K. Sullivan, and David G. Borkman.

Their research was published mainly in the Journal of Plankton Research, representing the key venue for disseminating their scientific findings.

The researcher was recognized as a Fellow of the American Association for the Advancement of Science (AAAS) in 1968, which represents a formal acknowledgment of their standing in the scientific community.
