Even with the nutrition provided by zooxanthallae, the process of building a reef is slow. Branching species grow 1020 mm per year while massive species grow 1 mm per year or less. Abiotic Factors and Coral Reefs Figure 3 The physiological constraints of sequestering calcium and carbonate ions from the environment and depositing a calcium carbonate skeleton set the physical boundaries that limit the distribution of corals. Both temperature and salinity affect calcification, restricting tropical coral reefs to waters between 2329C and in a salinity range of 3240 (Figure 5). The reliance of hermatypic (e.g., reef-building) corals on photosynthetic zooxanthallae to grow fast enough to produce reefs further limits coral reef distribution. Photosynthesis requires light, and the dependence of corals on zooxanthallae limits corals to shallow depths. Most reef building corals occur in less than 25 m of seawater. In addition, turbidity reduces light penetration, which restricts coral growth. High sedimentation rates can also bury or smother these sessile animals. While corals gain some nutrition from their symbiotic zooxanthallae, corals are heterotrophic because they capture zooplankton from the water column with their tentacles. As a sessile organism, corals must rely on currents to bring food as well as aid in gas exchange; however, high flow can reduce the ability of corals to capture food and waves can fracture and damage corals. Figure 5:Global distribution of coral reefs 2010 Nature Education All rights reserved. Zooxanthallae give corals their pigment, such that the loss of the zooxanthallae, either through death, exiting the host coral, or actually being consumed by the coral itself, is commonly referred to as “bleaching” due to the remaining visible white coral skeleton. Corals live at the uppermost boundary of their temperature tolerance. Even a 1C increase in sea surface temperature can stress zooxanthallae, causing corals to bleach (Glynn 1993). While bleaching can be fatal to corals, especially when bleaching occurs over a large portion of the coral colony, corals are able to recover, obtaining new zooxanthallae from the water column. In addition to the effects of temperature on reef health, increasing carbon dioxide concentrations in the atmosphere and subsequently the ocean lowers the pH a process referred to as ocean acidification. While the net impact of lower pH on coral reefs continues to be examined, decreases in pH can reduce the calcification rates of corals and other calcifying organisms (Ries et al. 2009). Formation and Zonation of Coral Reefs Figure 6 Charles Darwin first proposed the theory of atoll reef formation. He postulated that fringing reefs develop close to the shoreline in shallow waters around volcanic islands (Figure 6). As a volcanic island begins to subside into the ocean over geological time, the corals on these fringing reefs grow upward towards the light, maintaining and expanding the reefs position. As the island continues to subside, the shoreline becomes further from the reef and a shallow lagoon forms between the shore and the reef. These offshore reefs, or barrier reefs, protect the coast from ocean waves. Eventually, the island completely subsides into the sea, leaving an atoll, a ring of shallow reefs without any mainland. Scientific research on atolls in the mid-twentieth century supports the hypothesis of reef formation first described by Darwin over a hundred years earlier. Coral reefs can be separated into three distinct zones: the back reef, reef crest, and fore-reef (Figure 7). The back reef includes the shallow lagoon between the shore and coral reef. This habitat includes small patches of corals, sea grass beds, and sand plains. The back reef is often warmer because of the shallow depth, reduced water flow, and protection from waves. Salinity can also fluctuate due to fresh water inputs. In addition, sediment and runoff from shore can increase turbidity in this zone. The reef crest is the pinnacle of the reef and can be exposed to the air during extreme low tides. The reef crest is a harsh http://nytimes.com/2012/07/14/opinion/a-world-without-coral-reefs.html?pagewanted=all environment, with the potential for desiccation and UV stress associated with a shallow environment. In addition, breaking waves limit coral diversity to only a few species that can persist in this high-energy zone. The staghorn coral, Acropora cervicornis, can form dense monotypic stands along the reef crest. The thin branches of A. cervicornis aid the coral in asexual reproduction, with branches breaking off and moving during large storm events.
Florida group rebuilds vital coral reefs
“The coral reefs were so pretty. So many fish and so many neat things to see.” Nedimyer became a commercial fisherman and tropical fish collector, working in the ocean nearly every day of the year. But by the mid-1980s, he noticed a troubling trend. Two of the region’s most important corals, staghorn and elkhorn, were in drastic decline. The corals — tiny, stationary marine animals that make up the reefs — were dying because of many reasons, including climate change, pollution and overfishing, experts said. Today, they’re on the endangered species list. “The coral reefs of the Florida Keys are the most threatened and the heaviest-used coral reefs in the world,” said Billy Causey, southeast regional director of the National Marine Sanctuaries, an entity of the National Oceanic and Atmospheric Administration. Ken Nedimyer became worried watching coral reefs decline over the years. Now he’s doing something about it. Reefs are often referred to as the rainforests of the sea. They attract more marine life than anywhere else in the ocean because of the natural shelter they provide. But they’re declining worldwide, not just in Florida, and some scientists fear that they could all be gone by 2050. “Coral reefs provide protection for our coastal areas, habitat for fish and recreational opportunities for millions and millions of people,” Nedimyer said. “It’s very important to protect that whole ecosystem.” Reefs also have great economic value. Many people around the world depend on fisheries and the ocean for their livelihood. In the Florida Keys alone, more than 50 percent of the local economy is connected to a healthy marine environment. “If coral reefs died completely, entire economies would be disrupted,” Nedimyer said. As Nedimyer saw reefs die over the years, he became very concerned. A look at an underwater coral nursery “It became a consuming passion (for me) to try to find ways to protect and restore coral reefs,” he said. That passion led to Nedimyer starting the Coral Restoration Foundation , which has grown more than 25,000 staghorn and elkhorn corals in underwater nurseries. He and his staff of volunteers work three days a week maintaining the nurseries just off Key Largo. The nurseries cover more than an acre of the ocean floor. “Ken’s coral nursery is the largest in the wider Caribbean,” Causey said. “It’s probably 10 times larger than any others that I know of.” Do you know a hero? Nominations are open for 2012 CNN Heroes Nedimyer’s methods for growing corals have evolved over the years, but they’re all simple, easily duplicated and can be taught to anyone who can dive, he said. After the corals spend about a year growing in the nursery, they are transplanted to a reef in the wild. The goal is to get them to reproduce on their own and repopulate an area where they no longer exist. The Coral Restoration Foundation grows corals in underwater nurseries. After about a year, the corals are taken to the wild. “We’ve been able to recreate one of the biggest thickets in the Florida Keys of staghorn coral, and that’s something we can duplicate throughout the Keys and throughout the Caribbean,” Nedimyer said. Through education and awareness, Nedimyer has built a community committed to bringing coral reefs back to the Keys. His organization often collaborates with other groups, including the NOAA and the Nature Conservancy, a nonprofit conservation group. Nedimyer also spends a lot of time showing high school students his methods and working with them at his nurseries. “This isn’t just about me,” Nedimyer emphasized. “It’s about engaging a lot of people and training people, and I think it has a lot of hope.” The impact is already noticeable in areas where corals have been transplanted. Fish and other marine life are starting to come back, and Nedimyer is hopeful that in time, the Keys’ ecosystem will recover. “Most people think coral takes forever to grow, but some of these corals grow really fast,” he said. “They grow fast enough that we could make a big difference in a lifetime or less.” Nedimyer’s most ambitious project is just ahead. Within the next five years, the Coral Restoration Foundation plans to grow and transplant 50,000 corals in the Keys, which he says is the largest effort of its kind in Florida and the Caribbean. “Before, I felt helpless watching corals die,” Nedimyer said.
