THE DIET OF THE FLORIDA POMPANO (TRACHINOTUS CAROLINUS) ALONG THE EAST COAST OF CENTRAL FLORIDA
(1980)The diet of the Florida pompano (Trachinotus carolinus) was investigated hy examining stomach contents of adults from the Indian River and juveniles from the surf zone off Brevard County. Juveniles consumed primarily henthic ... -
SELECTED TRACE METALS IN THE UPPER ST. JOHNS RIVER AND THEIR LAND USE RELATIONSHIPS
(1981)Iron, copper and zinc were monitored in the water, sediments, and 4 species of fish of the upper St. Johns River, Florida. Surface water concentrations of total iron commonly exceeded 300 ug/l, the standard established by ... -
COMPARISON OF BENTHIC OXYGEN DEMAND MEASUREMENT TECHNIQUES
(1981)Several common methods to measure benthic oxygen demand were compared using measured and literature data. An in situ respirometer technique, a laboratory core-uptake technique and a laboratory flow-through system technique ... -
INFRARED ABSORPTION STUDY OF HUMIC SUBSTANCES FROM LAKE APOPKA SEDIMENT, PLANKTON AND THE SURROUNDING DRAINAGE BASIN
(1981)Infrared absorption spectra were run on humic substances from Lake Apopka sediment samples and compared with spectra from citrus and muck farm humic substances from sediment in the surrounding drainage basin, and also with ... -
PLANKTONIC FORAMINIFERA COLLECTED BY THE R/V MELVILLE (1972) IN THE SOUTHWEST ATLANTIC
(1981)The planktonic foraminiferal fauna was studied from 186 samples collected by the R/V Melville in the Southwest Atlantic Ocean during 1972. The samples were collected in the surface layer (horizontal tows) and throughout ... -
A redescription of Echinaster Modestus Perrier, 1881 (Asteroidea: Spinulosida) from the eastern Gulf of Mexico and the West Indies
(1981-05)The seastar Echinaster modestus Perrier, 1881, is redescribed and a lectotype is designated. Echinaster spp. from the west coast of Florida used in recent experimental studies are not E. modestus. -
Genetic recombination in Nocardia asteroides
(1981-09-04)Gene recombination between strains of N. asteroides of diverse origins has been demonstrated. In particular pairwise combinations, recombinants made up 0.01% of the population. All nine selectable recombinant classes were ... -
BENTHIC RESTING CYSTS OF GONYAULAX MONILATA HOWELL AND THEIR RELATIONSHIP TO RED TIDES IN THE INDIAN RIVER, FLORIDA
(1982)Gonyaulax monilata cysts were found in the sediments from 13 of 37 stations sampled in the Indian River, Florida. The distribution of cysts appears to be the result of 2 unrelated phenomena. In areas where blooms have ... -
LOCUS-OF-CONTROL IN AN INTERACTIONIST APPROACH TO BEHAVIOR
(1982)The impetus for this empirical study is: 1) to provide further construct validity for the I-E scale; and 2) to advance the locus-of-control construct as an important concept in the growing theoretical model of interactionism. ... -
BENTHIC TESTACIDA (RHIZOPODA, PROTOZOA) OF LAKE WASHINGTON, BREVARD COUNTY, FLORIDA
(1982)Benthic Testacida from sediments of Lake Washington were studied. The Testacida were extracted using standard foraminiferologic techniques. The determined taxa were photographed using scanning electron microscopy. Twenty-one ... -
TRACE METALS IN THE INDIAN RIVER LAGOON, FLORIDA: THE COPPER STORY
(1983)Inputs of copper from anti-fouling paints presently pose an environmental stress on some restricted embayments of the Indian River Lagoon, Florida. Over an 18 mo period, samples of water, suspended matter, sediments, ... -
FREQUENCY DISTRIBUTION PATTERNS AND PARTITIONING OF COPPER, IRON AND ZINC IN SELECTED TISSUES OF THE BLACK MULLET (MUGIL CEPHALUS)
(1983)Copper, iron and zinc concentrations were determined for muscle, gill and liver tissue from 45 black mullet (Mugil cephalus) collected in Turkey Creek, an embayment of the Indian River Lagoon, Florida. In the liver, Fe ... -
COMPUTER SIMULATION OF LIGHT ATTENUATION
(1983)A computer simulation model developed to study light attenuation in the ocean was applied to clear, medium turbid and turbid waters under diverse conditions. The model theory is based upon multiple small angle scattering ... -

THE OCCURRENCE OF A TOXIC DINOFLAGELLATE IN THE INDIAN RIVER SYSTEM
(1983)References to the toxic dinoflagellate, Gonyaulax monilata Howell, in the Indian and Banana rivers are compiled from published and unpublished sources. The inability of researchers to find motile cells for extended periods ... -
FACTORS INFLUENCING SEAGRASS ECOLOGY IN THE INDIAN RIVER LAGOON
(1983)Effects of water depth, water temperature, light intensity, epiphyte coverage, detrital accumulation and sediment resuspension and shifting on seagrass ecology in the Indian River Lagoon system were studied from April 1977 ... -
Activity coefficient and the Einstein relation
(1983-07-15)A connection between the activity coefficient of current carriers and the Einstein relations is established by two methods, one based on normal semiconductor concepts and one based on irreversible thermodynamics. The ... -
A NEW METHOD FOR IMPROVED FIXATION OF THE CHICK'S INNER EAR
(1984)Our method for fixation of the chick's inner ear involves puncturing the soft temporal bone with a needle and directly flushing the membranous labyrinth with cold glutaraldehyde. The temporal bone is trimmed and immersed ... -
Echinaster graminicola, a new species of spinulosid sea star (Echinodermata: Asteroidea) from the west coast of Florida
(1984-06)A new species of the sea-star genus Echinaster is described from shallow-water seagrass and oyster beds of the west coast of Florida. The new speciesand E. spinulosus Verrill are sibling species, morphologically ... -
ON FINITE ELEMENT METHODS FOR THE EULER-POISSON-DARBOUX EQUATION.
(1984-12)We deal primarily with the derivation of various convergence estimates for some semidiscrete and fully discrete procedures which might be used in the approximation of exact solutions of initial-boundary value problems with ...
