Ilsa Kuffner and team are heading to the Florida Keys and Dry Tortugas National Park to study the ecology of coral reefs

The team will conduct benthic surveys inside and outside the no take Research Natural Area at Dry Tortugas National Park (DRTO) to understand the processes of herbivory, or grazing, on coral reefs.

Relict Holocene coral-reef framework in the Florida Keys. Like many reefs in the western Atlantic, reefs here were just a few coral species: primary Acropora palmata and Orbicella spp. Recent disturbances have led to declines in the populations of those corals and relative increases in the abundance of more weedy taxa. The photograph was collected during fieldwork under permit DRTO-2018-SCI-0005 from the National Park Service.

Dr. Ilsa Kuffner is leading a team comprised of Nesti Stathakopoulos, BJ Reynolds, and Erin Lyons to complete coral-reef benthic surveys within and outside of the “no-take” Research Natural Area (RNA) at Dry Tortugas National Park. Their surveys will quantify the abundance of herbivores and macroalgae, and species richness of corals and gorgonians, and will be compared to baseline data collected in 2007—the year in which the RNA was established. The 2021 surveys will allow the team to detect changes in fish or benthic communities since the inception of the RNA regulations 14 years ago. These data will help assess changes to coral reef ecosystem food webs resulting from the 2007 management regulations and help park managers better understand the community structure on reefs in the Dry Tortugas.

Coral Reef Ecosystem Studies (CREST)

The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Measuring Coral Growth to Help Restore Reefs

It is critical to start measuring calcification rates in a systematic way now, particularly at subtropical latitudes where conditions fluctuate seasonally, so that we can understand how dynamic ocean conditions affect calcifying organisms today and predict possible changes in the future. We established a calcification monitoring network in the Florida Keys and have been measuring calcification...

Local-scale ecosystem resilience amid global-scale ocean change: the coral reef example

Coral reefs are massive, wave resistant structures found throughout the tropics, where they have long attracted attention for their beauty, ecological importance, and rich biological diversity. However, in recent years attention to these systems has focused on their downturn in health and the potential that they effectively could disappear within a century. Yet while many coral reefs have deterio

Reef communities in the Dry Tortugas (Florida, USA): Baseline surveys for the new no-take area

To understand the current community structure on reefs in the Dry Tortugas, we conducted specieslevel surveys of macroalgae, coral diversity, herbivorous and game fishes, urchins, and substratum composition (e.g., rugosity) in shallow (3- to 5-m depth) low-relief reef and hardbottom habitats in October 2007. We had particular interest in the ecological process of herbivory inside and outside of th
