Distribution and abundance of fishes associated with Sargassum mats in the northwestern Gulf of Mexico were examined off northern (Galveston) and southern (Port Aransas) Texas from May–August, 2000. A total of 36 species (17 families) was identified from larval purse seine collections. Individuals from seven species composed over 97% of the catch: planehead filefish Monacanthus hispidus (Linnae...

Eutrophication-induced hypoxic sites are increasingly reported in coastal regions. At the same time, ocean warming, water column stratification, and changing circulation lead to open-ocean deoxygenation. In areas reefs with dense vegetation, aquatic organisms can be exposed oxygen limitation stress where concentration reaches extremely low levels, particularly during nighttime once photosynthet...

The biosorption of heavy metals Hg(II) and Cu(II) from aquatic solution by biomass of dried Sargassum fusiforme was studied in the paper. The Sargassum fusiforme was able to absorb appreciable amount of mercury and copper from the aquatic solutions within 60 min of contact time with the metal solution and exhibited high removal of mercury and copper at low equilibrium concentrations. The specif...

BOTANY Ageratum is derived from the Greek “a geras,” meaning non-aging, referring to the longevity of the flowers or the whole plant. The specific epithet “conyzoides” is derived from “kónyz,” the Greek name of Inula helenium, which it resembles (Kissmann and Groth 1993). The synonyms of A. conyzoides include A. album Stend; A. caeruleum Hort. ex. Poir.; A. coeruleum Desf.; A. cordifolium Roxb....

A GC-MS analysis of underivatized alkaloids from leaves of Crinum latifolium was performed. From the identified 15 alkaloids, 9 were found for the first time in this plant. Almost all alkaloids belonged to the crinane type. Substantial changes in the methylation and oxidation pattern of the alkaloids at and after flowering were observed.

sea algae are widely consumed in the world. there are several seaweeds including brown algae which are authorized for human consumption. these plants contain important phytochemical constituents and have various potential biological activities. the present study investigated the presence of phytochemical constituents and total phenolic quantity of the seaweeds sargassum angustifolium , sargassu...

T H I S paper, the fourth in a series reporting the research on flowering response of cotton at College Station, Texas, presents the results of the quantitative analysis of an experimental strain of American Upland cotton, Gossypium hirsutum L. race latifolium, designated as Texas 86. Previous studies: In the first paper of this series, LEWIS and RICHMOND (1 957) reported observing three factor...

To assess distributional shifts of species in response to recent warming, historical distribution records are the most requisite information. The surface seawater temperature (SST) of Kochi Prefecture, southwestern Japan on the western North Pacific, has significantly risen, being warmed by the Kuroshio Current. Past distributional records of subtidal canopy-forming seaweeds (Laminariales and F...

Two of bioactive natural products were founded in a brown alga, Sargassum fulvellum. After isolation and purification, the molecular structures of these two products were investigated by NMR spectroscopy and GC-mass spectroscopy. The two compounds were identified to be 1-O-palmitoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)-glycerol (POGG) and 1-O-myristoyl-2-O-oleoyl-3-O-(alpha-D-glucopyranosyl)...
