Focused on coral photobiology, symbiotic interactions, and ecological niche partitioning

Abstract

This dissertation examines the interplay between light, the water column, and reef-building corals across multiple levels of biological organization—from individuals and populations to entire communities. Drawing on bio-optical modeling, ecological theory, laboratory analyses, and field experiments, I investigate how light availability shape the vertical distribution and biodiversity patterns of symbiotic corals.

In Chapter 1, I test the species–energy hypothesis to explain patterns of biodiversity in symbiotic coral communities along depth gradients. Chapter 2 addresses the physiological and ecological consequences of water optical degradation due to anthropogenic pollution, highlighting its impact on coral function and habitat quality. Finally, Chapter 3 explores how sibling coral species partition their niches in response to light gradients, emphasizing photoacclimation strategies and physiological trade-offs that facilitate coexistence.
