accessory pigments |
one of a class of pigments (such as fucoxanthin, phycobilin, and xanthophyll) that are present in various photosynthetic plants and that assist in the transfer of its energy to chlorophyll; also called masking pigment |
|
|
ahermatypic |
describing coral species lacking symbiotic zooxanthellae and incapable of secreting calcium carbonate at a rate suitable for reef production |
|
|
atoll |
a ring-shaped island of coral reefs and coral debris enclosing, or almost enclosing, a shallow lagoon from which no land protrudes. atolls often form over sinking, inactive volcanoes |
|
|
barrier reefs |
a coral reef surrounding an island or lying parallel to the shore of a continent, separated from land by a deeo lagoon. coral debris islands may from along the reef |
|
|
benthic |
of, in, or near the sea floor |
|
|
clumped distribution |
distribution of organisms within a community in small, patchy aggregations, or clumps; the most common distribution pattern |
|
|
coral reef |
a linear mass of calcium carbonate (aragonite and calcite) assembled from coral organisms, algae, molluscs, worms and so on. coral may contribute less than half of the reef material |
|
|
corals |
any of more than 6000 species of small cnidarians, many of which are capable of generating hard calcareous (aragonite, CaCO3) skeletons |
|
|
desiccation |
drying |
|
|
estuary |
a body of water partially surrounded by land where freshwater from a river mixes with ocean water, creating an area of remarkable biological productivity. |
|
|
fringing reefs |
a reef attached to the shore of a continent or island |
|
|
fungi |
a type of multi cellular heterotroph that obtains nutrients by extracellular digestion and absorption |
|
|
hermatypic |
describing coral species possessing symbiotic zooxanthellae within their tissues and capable of secreting calcium carbonate at a rate suitable for reef production |
|
|
intertidal zone |
the marine zone between the highest high-tide point on a shoreline and lowest low-tide point. the intertidal zone is sometimes subdivided into four separate habitats by height above tidal datum, typically numbered 1 to 4, land to sea |
|
|
kelps |
informal name for any species of large phaeophyte |
|
|
mangroves |
a large flowering shrub or tree that grows in dense thickest or forests along muddy or silty tropical coasts |
|
|
motile |
able to move about |
|
|
multicellular algae |
algae with bodies consisting of more than one cell. examples are kelp and Ulva |
|
|
phaeophyta |
brown, multicellular algae, including kelps |
|
|
polyp |
one of two body forms of Cnidaria. polyps are cup-shaped and possess rings of tentacles. coral animals are polyps |
|
|
random distribution |
distribution of organisms within a community whereby the position of one organism is in no way influenced by the positions of other organisms or by physical variations within that community; a rare distribution pattern |
|
|
reefs |
a hazard to navigation; a shoal, a shallow area, or a mass of fish or other marine life |
|
|
rhodophyta |
red, multicellular algae |
|
|
rocky intertidal zone |
the band between the highest high-tide and lowest low-tide marks on a rocky shore |
|
|
sessile |
attached; nonmotile; unable to move about |
|
|
unicellular algae |
algae with bodies consisting of a single cell. examples are diatoms and dinoflagellates |
|
|
uniform distribution |
distribution of organisms within a community characterized by equal space between individuals (the arrangement of trees in an orchard); the rarest natural distribution pattern |
|
|
wave shock |
physical movement, often sudden, violent, and of great force, caused by the crash of a wave against an organism |
