Heterotrophic eukaryotic unicellular organisms that belong to the kingdom Protista.

High-resolution (1-2 meter resolution) imaging satellite; the world's first commercial satellite for imagery of this type.

If the temperature is kept constant, the volume of a given mass of gas is inversely proportional to the absolute pressure.

In a statistical hypothesis test, the P value is the probability of observing a test statistic at least as extreme as the value actually observed, assuming that the null hypothesis is true. This probability is then compared to the pre-selected significance level of the test. If the P value is smaller than the significance level, the null hypothesis is rejected, and the test result is termed significant; the significance of a statistical test. P-values of less than 0.05 are generally considered to be an indicator that a statistical model is significant; a quantitative estimate of the probability that the observed difference between two groups could have happened by chance alone.

In all species of fishes, the older larger females produce more eggs than the younger smaller ones. In some species, the larger older females can produce exponentially greater quantities of eggs. The BOFFF hypothesis refers to this phenomenon.

In general, closely related species do not have identical ranges, but often their ranges are not very far apart. They are usually adjacent but separated by some kind of a geographic barrier, such as a mountain, desert, or river. A second Jordan's Rule is: fishes develop more vertebrae in cold environments than in warm ones.

In genomics, the DNA affixed to a microarray; a small piece of nucleic acid that has been labeled with a radioactive isotope, dye, or enzyme that is used to locate a particular nucleotide sequence or gene on a DNA molecule.

In response to the dramatic increase of coral diseases observed over recent years, the U.S. Coral Reef task force (2002) recommended the creation of the CDHC from a cross-section of internationally recognized experts in coral diseases, biomedical and veterinary sciences, pathology, chemistry, biology, biotechnology, and marine management. It organizes and coordinates the scientific resources of the U.S. and its territories to meet the challenge of globally declining coral reefs.

In situ NOAA meteorological and oceanographic monitoring sites that collect data continuously which are transmitted hourly via satellite to a data archival site. An automated system (hardware and software) that monitors select oceanographic and meteorological parameters and produces specialized alerts when conditions may result in environmental stresses conducive of coral bleaching. NOAA plans to expand the CREWS from the Florida Keys/Bahamian sites to many remote coral reef sites throughout the world.

In statistics, a method for comparing treatment group means after The analysis of variance (ANOVA) null hypothesis that the expected means of all treatment groups under study are equal, has been rejected using the ANOVA F-test. If the F-test fails to reject the null hypothesis this procedure should not be used.
