Speciation in which the new species forms from a population contiguous with the ancestral species' geographic range. The evolution of reproductive isolating mechanisms occurred when the population entered a new niche or habitat within the range of the parent species.
Industry:Natural environment
The elastic part of a bivalve (Mollusca) shell that unites the valves along the top of the shell.
Industry:Natural environment
The posterior opening of the digestive tract, through which waste products of digestion are released.
Industry:Natural environment
The tissues of the primary reproductive organs that produce eggs and sperm cells.
Industry:Natural environment
The MPRSA (1972) provides protection for many coral reefs by authorising NOAA to designate areas as marine sanctuaries and promulgate regulations for the conservation and management of those areas. Since the Act was passed, thirteen sanctuaries have been designated, several of which contain coral reef communities. Coral research, monitoring, and management activities are conducted in these sanctuaries, as well as in the Northwestern Hawaiian Islands Coral Reef Ecosystem Reserve, which is currently (June 2004) under consideration to become the nation’s fourteenth sanctuary.
Industry:Natural environment
A chemical agent specifically designed and used to kill or inhibit the growth of algae; also called 'algicide'.
Industry:Natural environment
A flow that sustains a balance between Coriolis deflection and a pressure gradient.
Industry:Natural environment
A massive colony that has corallite mouths aligned in valleys, such that there are no individual polyps.
Industry:Natural environment
A process whereby the metabolic balance of a cell is disrupted by exposure to environmental substances, resulting in the accumulation of free radicals, which can damage components of cells' membranes, proteins or genetic material by "oxidizing" them.
Industry:Natural environment
A statistical technique applied to data to determine the degree of correlation of a dependent variable with one or more independent variables, in other words, to see if there is a strong or weak cause and effect relationship between things; a statistical process for fitting a line through a set of data points. It gives the intercept and slope(s) of the “best fitting” line. It tells how much one variable (the dependent variable) will change when other variables (the independent variables) change.
