Ralph Saporito

Ralph Saporito is an Associate Professor and Graduate Program Director in the Department of Biology at John Carroll University, teaching courses including Human Anatomy & Physiology, Principles of Biology, and Tropical Field Biology to advance undergraduate and graduate biological sciences education.

His academic credentials include a B.S. and Ph.D. in Biology from Florida International University, followed by an NSF Postdoctoral Research Fellowship at Old Dominion University.

Dr. Saporito's research program investigates the ecology and evolution of antipredator adaptations, with specialized focus on chemical defenses and aposematism in vertebrates. He examines how poison frogs sequester alkaloids from arthropod prey through integrative field and laboratory approaches spanning ecology, evolution, behavior, morphology, and chemical analysis. His work reveals critical insights into predator-prey coevolution and chemical signaling dynamics in tropical ecosystems.

Analysis of his 2018-2019 publications shows consistent exploration of warning signal evolution, maternal alkaloid transfer mechanisms, aposematic signaling honesty, mimicry systems, and antimicrobial properties of sequestered compounds. These studies demonstrate interdisciplinary integration of chemical ecology, evolutionary biology, and herpetology to decode defense strategies in amphibians.

Key recognition includes:

• NSF Postdoctoral Research Fellow

As Graduate Program Director, Dr. Saporito mentors graduate students and oversees Biology program administration. His Chemical Ecology Lab secures research funding for tropical fieldwork and laboratory analyses, maintaining international collaborations. Current and alumni lab members contribute to ongoing projects examining chemical sequestration in dendrobatid frogs.

The Chemical Ecology Lab at John Carroll University, directed by Dr. Saporito, operates active tropical field sites and maintains research partnerships globally. The team investigates chemical defense mechanisms in amphibians and reptiles, particularly poison frog-arthropod interactions, advancing understanding of ecological and evolutionary processes in chemical defense systems.
