Reef Tract

Through an ecocinema lens, an unconventional corpus of photographs of Carysfort Reef, one of seven iconic coral reefs along the Florida Reef Tract, represents something of an extreme time-lapse series. In the absence of a cohesive underwater documentary record at the time when the Florida Reef Tract is undergoing the most extensive reef restoration in the world, speculation allows us to search for patterns in damaged places with incomplete information and practice a form of multispecies storytelling of our encounters. Taken in 1966, 2003, 2014, and 2019, these images are evidence of cultural moments in our changing relationship with this reef in the context of anthropocentrism, the emergence of an alternative environment spectatorship of awareness, and a baseline for localized social change.

Two main hypotheses have been developed for describing the role and importance of the sea urchin Diadema antillarum on reefs of the Caribbean region in both space and time. The first and most crucial is whether D. antillarum was the most important “keystone” grazer on Caribbean reefs? The alternate to this hypothesis is that D. antillarum was merely a redundant species, playing a secondary role to herbivorious fishes which only came into dominance after herbivorous fishes had been removed by man through exploitive fishing practices. To resolve this debate, we pose the question: “What is the role of Diadema antillarum in altering the composition of the benthic community on Caribbean coral reefs in time and space?” The interpretation presented herein implies that D. antillarum was and is the most important shallow-water herbivore on Caribbean coral reefs. This is contrary to a prevailing model but in substantial agreement with the historical importance of the species. If correct, the continued and future recovery of this sea urchin may be the key ingredient to facilitating coral reef recovery throughout the region. In addition, on coral reefs where the natural recovery of Diadema has been delayed or is absent (e.g. the Florida Reef Tract); measures to actively restore these urchins may be the most efficient and cost-effective tool for conserving and enhancing the ecological function of reefs. This debate also emphasizes the requirement for implementing ecologically-based, not ideologically-based management of natural systems.

The Florida Keys, a delicate archipelago of sub-tropical islands extending from the south-eastern tip of Florida, host the vast majority of the only coral barrier reef in the continental United States. Stony Coral Tissue Loss Disease (SCTLD), which was first detected near Virginia Key in 2014, has spread throughout the Florida Reef Tract and to reefs throughout the Caribbean, af-fecting nearly all reef-building corals. Molecular studies of SCTLD have identified opportunistic pathogens associated with the disease, but so far no single pathogen can be clearly pinpointed as its cause. One focus of recent research has been the surrounding environment of the corals, coined the 'coral ecosphere'. Abiotic and microbial components of the coral ecosphere are pivot-al for understanding the health of a reef, and could play an important role in SCTLD in Florida. In this study, we analyzed microbial community structure and abiotic factors that can impact coral (and human) health. Both, bacterial and eukaryotic community structure were significantly linked with variations in temperature, dissolved oxygen and total organic carbon values. High abundances of copiotrophic bacteria as well as several potentially harmful microbes, including coral pathogens, fish parasites, and taxa that have been previously associated with Red Tide and shellfish poisoning, were present in our datasets and can have a pivotal impact on coral health in this ecosystem.
