Ilsa B Kuffner, Ph.D.
Ilsa Kuffner is a Research Marine Biologist at the St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida.
As a research marine biologist for the Coastal and Marine Geology Program, I investigate the causes and effects of coral reef degradation. I explore local- to global-scale stressors on reefs, and experimentally determine how environmental variables such as sea-surface temperature, water quality, seawater chemistry, nuisance macroalgae, and ocean acidification affect coral growth, the community structure of reefs, and the process of reef building. My work informs resource managers about the mechanisms causing reef degradation and how management efforts may be improved to protect and restore degraded reefs. Please visit the USGS Coral Reef Ecosystems Studies (CREST) website for more information (see link below).

Collection methods and descriptions of coral cores extracted from massive corals in Dry Tortugas National Park, Florida, U.S.A. Collection methods and descriptions of coral cores extracted from massive corals in Dry Tortugas National Park, Florida, U.S.A.
Cores from living coral colonies were collected from Dry Tortugas National Park, Florida, U.S.A., to obtain skeletal records of past coral growth and allow geochemical reconstruction of environmental variables during the corals’ centuries-long lifespans. The samples were collected as part of the U.S. Geological Survey Coral Reef Ecosystems Studies project (http:/coastal.er.usgs.gov/crest...

The structure and composition of Holocene coral reefs in the Middle Florida Keys The structure and composition of Holocene coral reefs in the Middle Florida Keys
The Florida Keys reef tract (FKRT) is the largest coral-reef ecosystem in the continental United States. The modern FKRT extends for 362 kilometers along the coast of South Florida from Dry Tortugas National Park in the southwest, through the Florida Keys National Marine Sanctuary (FKNMS), to Fowey Rocks reef in Biscayne National Park in the northeast. Most reefs along the FKRT are...

A geological perspective on the degradation and conservation of western Atlantic coral reefs A geological perspective on the degradation and conservation of western Atlantic coral reefs
Continuing coral-reef degradation in the western Atlantic is resulting in loss of ecological and geologic functions of reefs. With the goal of assisting resource managers and stewards of reefs in setting and measuring progress toward realistic goals for coral-reef conservation and restoration, we examined reef degradation in this region from a geological perspective. The importance of...

Coral calcification and ocean acidification Coral calcification and ocean acidification
Over 60 years ago, the discovery that light increased calcification in the coral plant-animal symbiosis triggered interest in explaining the phenomenon and understanding the mechanisms involved. Major findings along the way include the observation that carbon fixed by photosynthesis in the zooxanthellae is translocated to animal cells throughout the colony and that corals can therefore...

A new record of the late Pleistocene coral Pocillopora palmata from the Dry Tortugas, Florida reef tract, USA A new record of the late Pleistocene coral Pocillopora palmata from the Dry Tortugas, Florida reef tract, USA
Pocilloporid corals dominated shallow-water environments in the Caribbean during much of the Cenozoic; however, the regional diversity of this family declined over the last 15 My, culminating with the extinction of its final member, Pocillopora palmata, during the latest Pleistocene. Here we present a new record of P. palmata from Dry Tortugas National Park in the Florida Keys and infer...

USGS research on Atlantic coral reef ecosystems USGS research on Atlantic coral reef ecosystems
Overview Coral reefs are massive, biomineralized structures that protect coastal communities by acting as barriers to hazards such as hurricanes and tsunamis. They provide sand for beaches through the natural process of erosion, support tourism and recreational industries, and provide essential habitat for fisheries. The continuing global degradation of coral reef ecosystems is well...
