stenohaline
models with a systematic part and a random part, both containing only a
limited number of quantities, called parameters. Assuming some probability distribution, parameters can be estimated and hypotheses concerning
these parameters can be tested. To give an example: a sample containing
hundreds of Xi> x 2 observations can be characterized as being bivariate normally distributed, with the means and variances of Xl and X 2 and the correlation coefficient between Xl and X 2 as parameters. The hypothesis that the
correlation coefficient equals zero can be tested; (2) estimated parameters.
Known statistics for a number of samples are mean (x), variance (S2), standard
deviation (s), standard error of mean and the correlation coefficient. The standard
error of mean is often used to describe limits to the reliability of sample
means as an estimate of population means. The standard error of mean
decreases as n increases, i.e., when more samples are taken the reliability of
estimates of population parameters increases. However, the standard error
of mean does not provide a mathematically objective criterion. Statistically
computed confidence limits are easier to interpret.
statocyst organ of balance (orientation of the gravitation), consisting of a chamber containing statoliths, i.e., granules of lime, sand, etc., which stimulate
receptor cells when the animal changes direction. ~otolith.
Stefan's law this physical law, also known as the Stefan-Boltzmann law, states
that a body emits an amount of radiation energy proportional to the fourth
power of the absolute temperature. In this way the earth, including the ocean
surface, loses to outer space energy received earlier from solar radiation.
This radiation is measured by remote sensing techniques in order to determine
the temperature of the ocean surface.
steno- prefix, meaning narrow.
stenobath refers to species that can tolerate only small variations in pressure
(depth).
stenoecious refers to a species that can only live in a environment in which conditions fluctuate within narrow limits. Most marine organisms are stenoecious, in contrast to estuarine species, which can usually withstand large
fluctuations in environmental parameters; opposite of euryoecious.
stenohaline refers to species that can only tolerate narrow changes in environmental salinity, and thus are unable to tolerate a wide variation in osmotic
pressure of the environment. Animals of the open sea are usually stenohaline: they will not invade the brackish water of estuaries. Many brackishwater animals are the opposite, euryhaline, capable of tolerating large changes
in environmental salinity. Most freshwater species are also stenohaline, but
