Skeletal Coral

Skeletal Coral

Skeletal coral is the calcium carbonate structure that remains after the coral animals have died.

CMap

Algae are aquatic, photosynthetic plant-like organisms and include calcareous macroalgae, fleshy macroalgae, turf algae, and crustose coralline algae. Anemones & zooanthids are cnidarians very similar to coral, but are not characteristic reef builders. Sand production is the process by which calcified coral skeletons and invertebrate shells break down, forming sand which replenishes beaches. Biochemical & genetic resources are the naturally available novel biochemicals and genetic information found in coral reef organisms that can be utilized for animal breeding or development of biotechnology. Biocriteria are narrative expressions or numeric values that describe the biological condition (structure and function) of aquatic communities inhabiting waters of a designated aquatic life use. Biological monitoring is the use of a biological entity as a detector and its response as a measure to determine environmental conditions. Biological monitoring, mapping, and scientific research are activities to track the condition of populations, communities, and habitat, and to understand the processes, stressors, and ecological interactions that affect that condition. Carbon storage and cycling is the ability of an ecosystem to utilize, process, and store carbon. Complex habitat and resources reflects the complex architecture of sessile, plant-like organisms, such as octocoral and sponges, which provides shelter and protection for small fish and other invertebrates from predators. Contact Uses, such as biological additions, physical damage, and biological harvesting, are activities in which humans create pressures through direct contact with the ecosystem. Coral is a colonial marine animal consisting of polyps. Coralline algae is a low-growing type of algae on reefs that has calcareous deposits. Corallivorous fish are fish whose diet primarily consists of live coral. Cultural services are the nonmaterial benefits people obtain from ecosystems through spiritual enrichment, cognitive development, recreational opportunities, aesthetic experiences, sense of place, and educational and research opportunities. Discharges are the intentional or unintentional distribution of chemicals, debris, or other pollution, into the environment as a consequence of human activities. Ecosystem monitoring and restoration refers to responses to directly alter the condition of the reef ecosystem through restoration or remediation activities, setting limits on degradation through biological criteria or water quality criteria, or improving knowledge through monitoring, mapping, and scientific research. Ecosystem services are the benefits people obtain from ecosystems . Fish are cold-blooded aquatic vertebrates that breathe through gills and usually have scales. Hydrocorals (millepora) are a taxonomic class of very small, predatory cnidarians that can be solitary or colonial. Invasive species are plants, animals, or other organisms that are foreign to a particular environment, and whose introduction may be detrimental when invasives compete with or consume native species. An Invertebrate is any animal that lacks a backbone. Landscape Changes are alterations of the natural landscape through human activities, including coastal development, shoreline armoring, impervious surfaces, deforestation, or soil disturbance, which can alter water flow patterns and lead to pollutant runoff into coastal systems. Large herbivorous fish are any large bodied fish that primarily feed on algae, such as parrotfish and chubs. Marine products are non-food goods derived from reefs that promote human well-being (e.g, aquarium fish or ornamental resources) and human health (e.g., pharmaceuticals and cosmetics). Any worm that lives in a marine environment is considered a marine worm. Microorganisms are microscopic plants or animals, such as cyanobacteria and disease-causing pathogens that live in coral reef ecosystems. Molluscs are marine invertebrates with soft, unsegmented bodies, such as clams, squid, and snails. Octocorals are thick and fleshy, colonial marine animals resembling stony corals in polyp size, but lacking calcium carbonite skeletons. The Reef Ecosystem includes a suite of abiotic variables that form the physical and chemical environment. Pressures are human activities that create stress on the environment. Provisioning services are the products or ecosystem goods obtained from ecosystems, including seafood, genetic and biochemical resources, pharmaceuticals, ornamental resources, and water resources. The state of the Reef Ecosystem is the condition, in terms of quantity and quality, of the abiotic and biotic components including physical, chemical, and biological variables. Reef Habitat is the abundance, distribution, and condition of the benthic components of the reef ecosystem. Reef Inhabitants are all of the motile components of the reef ecosystem, including fish, invertebrates, marine reptiles and mammals, and are quantified by their abundance, distribution, and condition. Reef Life is the abundance, distribution, and condition of the biological components of the coral reef ecosystem. Regulating Services are benefits obtained from ecosystem processes that regulate the environment, including erosion regulation, natural hazard regulation, and climate regulation. Responses are actions taken by groups or individuals in society and government to prevent, compensate, ameliorate or adapt to changes in Ecosystem Services or their perceived value. Sea Urchins are small, spiny echinoderms that can be found in coral reef ecosystems. Skeletal coral is the calcium carbonate structure that remains after the coral animals have died. Snails and Conch are Mollusks that can be found in the coral reef ecosystem. Socio-Economic Drivers include the sectors that fulfill human needs for Food & Raw Materials, Water, Shelter, Health, Culture, and Security, and the Infrastructure that supports the sectors. Sponges are sessile colonial animals with soft porous bodies supported by a fibrous skeletal framework. Scleractinian, or stony corals, are marine animals with hard skeletons composed of calcium carbonate. Supporting services are ecological processes that indirectly benefit humans by maintaining a functional ecosystem for the production of other ecosystem goods and services. Wetland and reef restoration are activities to directly improve, reestablish, or repair degraded ecosystems. Zooxanthellae are flagellate protozoa that are golden-brown intracellular endosymbionts of various marine animals and protozoa, especially anthozoans such as the scleractinian corals

CMap Description

Coral provide the basis for all reef ecosystem services and thus the well-being and welfare supplied by the coral reef ecosystem. Stony coral produces large quantities of calcium carbonate skeleton that may persist in the marine environment long after the colony has died. The resulting carbon storage & cycling builds the physical structure of the reef and results in the other supporting services of complex habitat & resources and reef structural strength, and ultimately results in sand & land production. Physical damage and ocean acidification can affect the strength and dissolution rates of coral skeletons, and thus the persistence of habitat and wave attenuation that they provide. Monitoring and research can be implemented to better understand the role of coral skeletons in the reef ecosystem.

Monitor & Research: Biological Status and Trends Monitoring This activity produces long-term comprehensive information on sanctuary-wide status and trends of biological resources. Data that could be collected on coral reef communities includes but is not limited to species abundance and density, biodiversity, benthic cover, coral condition, growth, recruitment, predation, and grazing. Mangroves and seagrasses should also be monitored. With adequate baseline data, changes in community structure and biocriteria can be identified and restoration or protection efforts can be taken.

Restoration: Restore Reef Habitat and Salvage Benthic Inhabitants Injured by Physical Damage This management approach involves salvaging, maintenance, and re-stabilization or injured resources by management staff and private contractors in order to rescue and provide first aid following physical damage such as vessel groundings. This can be achieved using Reef Medics and other volunteer programs because these groups have experience with vessel navigation and operation, snorkeling, and SCUBA diving. Also, it allows for researchers to collect living coral material when relocation of such organisms is not possible. Salvage and re-stabilization is not limited to the living coral; octocorals, seagrasses, and the non-living framework may all be damaged of destabilized from groundings or other physical impacts. In addition to the habitat's structural integrity, it is important to re-establish aesthetics and ecological functionality. Funds from mitigation and case settlements should be used for this work, as long term costs of restoration and monitoring can be extensive. NOAA Marine Sanctuary Program. 2007.

Restoration: Removal of Invasive Algae Benthic organisms on reefs maintain a delicate balance competing for space. In many areas, the competition between coral and algae has fallen out of balance due to confounding factors. Factors such as decreased herbivorous fish and invertebrates, and invasive algae species have allowed faster growing algae to take over many reefs, often growing into smothering mats that cover and kill coral. In Hawaii, there has been some success physically removing invasive algae such as Kappaphycus using underwater vacuums extended down from barges or volunteer events in shallower areas.
