SARGASSUM ,PLANT species ,BIOLOGY ,VEGETATION dynamics ,PLANT communities - Abstract
The article discusses a study which investigated the species of Sargassum found along the coasts of the Danish West Indies with remarks upon the floating forms of the Sargasso Sea. The Sargassum species include Sargassum vulgare, found on both exposed and sheltered places. The second part of the study deals with the floating Sargassum found in the Sargasso Sea, which are referred to as Sargassum natans and a coarser form which the author called Sargassum hystrix. The biology, affinities and origin of the floating pelagic gulfweed forms are also discussed.

The behaviour towards periodate of the brown-algal polysaccharide sargassan before and after partial hydrolysis, alkali treatment, and methanolysis has been studied. Evidence is thereby provided that the sargassan backbone is composed of (1→4)-linked β- D -glucuronic acid and β- D -mannose residues. Heteropolymeric, partially sulphated branches are attached to the backbone, and these branches comprise various proportions of(l→4)-linked, β- D -galactose, β- D -galactose 6-sulphate, and β- D -galactose 3,6-disulphate residues, (1→2)-linked α- L -fucose 4-sulphate residues, and (1→3)-linked β- D -xylose residues.

North of 30°N Sargassum production averaged about twice that to the south, possibly related to the degree of winter mixing. Production rates were relatively high in continental shelf areas or near land masses but showed no major seasonal variations nor was there an obvious relationship with concentrations of NO2, NO3, NH3, and PO4. Under normal daylight conditions in October Sargassum photosynthesizes at a maximum rate. Average carbon turnover time is no more than 40 days and Sargassum and its epiphytes contribute no more than 0.5% of the total primary production in the western Sargasso Sea. Carbon turnover rate of the epiphyte Dichothrix exceeded that of its host Sargassum by an average of fourfold. Dichothrix production on the shelf averaged as much as 15% of the pelagic macroalgal production in October. Dichothrix is most abundant in the continental shelf waters and lowest in the Sargasso Sea; this distribution may be related to the available iron in the seawater.

The succession of epibionts on gulf-weed, Sargassum natans (L.) Meyen, is described. Only the hydroid Clytia noliformis (McCrady) colonizes the newest algal growth, spreading rapidly from below towards the frond tips by means of stolons. The remaining species — the bryozoon Membranipora tuberculata (Bosc), the spirorbid Janua formosa (Bush) and the blue-green alga Calothrix crustacea Schousb. & Thurs. — establish themselves through a free-swimming phase but, instead of attaching near the meristem as is usual on other algae, the larvae and hormogonia (dispersal phase of Calothrix ) settle well away from the growing tip of the Sargassum . Such behaviour is consistent with the view that tannins present in the young thallus inhibit the establishment of the surface microflora which is a pre-requisite for the settlement of larger epibionts. Janua shows a strong preference for the bladders of the Sargassum , and Calothrix for the leaflets; but Membranipora appears to settle equally well on bladders, leaflets, and stem. Observations on young colonies of Membranipora reveal that the metamorphosing larvae were orientated with respect to the axis of the Sargassum leaflets. Water flow, which has previously been considered as likely to provide a directional stimulus for such orientation, cannot be the operative factor in this case.

An investigation of the effect of seasonal variation on the composition of three brown algae showed that Cystoseira was richer in its mannitol content (10·7%) than Sargassum (6·7%). In all three species, laminarin ranged from 2·24% to 4·42% during most months but was absent in June. Alginic acid content (30–32%) was at its maximum in August for the two Cystoseira species but was high both in April and August in S. linifolium. The uronic acid composition of alginic acid as well as the fucose and galactose contents of the algal species showed definite seasonal variation.

Côr das águas de Sepetiba; as pròpriamente marítimas, pela Escala de Forel e as outras côres aparentes totais feitas por comparação com escalas de SÉGUY e com o Dicionário de Côres de MAERZ & PAUL, 1950. Côr Forel nº6 mostrava no litoral cirrípedes como a Tetraclita squamosa, nas rochas; Águas com a cianofícea planctônica Trichodesmium erythraeum tinham côr de "fôlha de bananeira" ou alpine green. O verde esmeralda mais intenso no local 7, com plancto maciço da diatomácea Coscinodiscus; a parte central da Baía com 150 [quilometros quadrados], cheia de larvas de camarão Penaeus schmidti, águas de cõr de ferrugem nas superfícies das águas; os estuários côr caramelo, isabellinus e bistre. Êste levantamento preliminar serve para comparações futuras, pois a Baía de Sepetiba ainda não é poluída. Futuramente haverá um pôrto de minérios com 3.000.000 de toneladas anuais, cais do pôrto, siderúrgicas e outras indústrias que a poluirão. Várias cõres de águas poluídas da Baía de Guanabara, como águas negras, águas côr de asfalto e outras escurecidas não foram encontradas em Sepetiba. Também não foram encntradas "águas vermelhas" com plancto predominante de dinoflagelados do que já vimos na Baía de Guanabara seguidos de mortandadas de peixes. A fig. 3 mostra as curvas de transparência, e a relação entre côr e transparência é dada para as côres totais aparentes. Foi marcado o coeficiente de extinção da luz K, pelo cálculo a partir do Disco de Secchi. Havendo poluições todos êsses dados que apresentamos deverão ser alterados. The apparent total color of sea by comparison with samples tested by "MAERZ & PAUL: A Dictionary of Colors, 1950". We find green colors of Forel Scale: Forel n. 5 in waters with Pheophyceae, Sargassum, and Rhodophyceae; Forel n. 6 waters in stones with the Cirripedia, the barnacle Tetraclita squamosa; the alpine green in waters with Trichodesmium exuthraeum. Emerald green in the localities with blooms of the diatom Coscinodiscus. The central portion of the bay, 150 Km[squared] hole-green, full of larvae of shrimps Penaeus schmidti; some shoals of shrimps moves its pleopods and by displacement of botton with diatoms and reddish sediment produces a rust color spot in surface of waters seen by fishermen. The estuaries are Isabell color, and caramel. That is a preliminar survey, to future comparison, because to day Sepetiba Bay is not polluted. But futurelly, it will be polluted by an harbour for 3.000,000 tons of iron ore, and by a quay for cargo boats, and siderurgy mills, airports, and other industries. Several polluted waters of Guanabara Bay are black and asphalt color, and cub color. That colors are not found in Sepetiba Bay to day. In 1965, we do not find the "red waters" and "red tides" with blooms of dinoflagellates in Sepetiba Bay, that they are present sometimes in Guanabara Bay with mortalities of fishes. Sepetiba Bay is not biologic problem, to day, is not polluted. The fig. 3 shows a map of transparence of waters by the disc of Secchi and a relation is given of color and transparence, in Sepetiba: Forel color 5: transparence 2.8 m to 2.9 m; Forel n. 6: 2.0 m; Forel color n. 7: 1.0 m to 1.5 m. Moss green waters: 0.6 to 1.5 m; hellebore green waters: 0.9 to 1.5 m; emerald green waters: 2.0 m to 2.2 m; In Guanabara Bay, into the polluted Enseada de Inhaúma: asphalt color waters: 0.02 - 0.05 m; and in black waters: trasnparence of 1 cm. The extintion koeficient of light is indicated in explanation of the fig. 3.

1. Observations were made on the floating seaweeds in Sagami Bay and some relations between fish and floating seaweeds were studied.2. The floating seaweeds were most frequent in March and then they become scarce gradually and in August only very small amount of fragments of Sargassum were found.3. Though no appreciable relation between the size of floating seaweeds and the number of fish gathered around them was observed in general, there is a possibility that some relations between them would be found when comparison is made among restricted samples in season and locality.4. The duration of stages gathering around the floating seaweeds of Oplegnathus fasciatus was estimated at about one month but it seems to be much variable by individuals.

1. 1. Chlorophyll c, isolated from a variety of marine algae, is a mixture of two spectrally distinct components, chlorophylls c1 and c2, which were separated on thin layers of a special Dow polyethylene powder. Each component possessed the typical three-banded chlorophyll c spectrum, but the band ratios of chlorophyll c2 in diethyl ether, acetone and methanol were significantly higher than those of chlorophyll c1, and absorption maxima were shifted several nm to higher wavelengths. In diethyl ether, the absorption maxima of chlorophyll c1 from Sargassum flavicans were at 444.5, 578.6 and 628.2 nm with band ratios of 10.1, 0.68 and 1.00, respectively, whereas absorption maxima of chlorophyll c2 were at 448.5, 581.8 and 628.8 nm with band ratios of 14.5, 1.13 and 1.00, respectively. 2. 2. Preparations of chlorophyll c1 from a variety of different algae were spectrally identical, as were those of chlorophyll c2. Both chlorophylls c1 and c2 were present in brown seaweeds, diatoms and chrysomonads, but only chlorophyll c2 was found in dinoflagellates, symbiotic dinoflagellates and cryptomonads. Chlorophyll c2 was the universally distributed component. 3. 3. Chlorophylls c1 and c2 were extremely susceptible to aggregation, and these changes were accompanied by a loss in intensity of the absorption bands. Storage of chlorophyll c2 solutions in the cold under ceratin conditions favoured the formation of a third chromatographically and spectrally distinct chlorophyll c compound, with properties suggestive of a chlorophyll c aggregate. The presence of spectrally different components in chlorophyll c preparations, their varied distribution in the marine algae, and their ease of aggregation provide an adequate explanation for differences in absorption spectra and extinction coefficients recorded by different authors.

Pelagic Sargassum was collected in late summer, late winter, and early and late spring from inshore waters, the Gulf Stream and the Sargasso Sea of the Western North Atlantic Ocean. The noncolonial macrofauna was picked from the weed samples. The 34 samples contained 67 species and 11,234 individuals. The Shannon-Wiener index of diversity had a mean value of 2.419±0.177 (t.05s x − ) and a statistical range between 1.401 and 3.437 (t.05 s). Mean diversity values were not significantly different among the various sampling series, and diversity did not vary with raft volume. High diversity values were related to an equitable distribution of species resulting from a stable environment and an area low in productivity. Species composition of the Sargassum organisms varied seasonally and geographically. Animals were more abundant in the spring than in the fall samples. Samples collected on a transect in the Gulf Stream and Sargasso Sea maintained a similar faunal composition.

1. Turbinaria turbinata occurs in Puerto Rico, mostly on the northern or Atlantic side, on rocky substrata in shallow depressions or to a depth of 5 feet. 2. Plants are commonly of one sex, but not infrequently hermaphroditic as well as antheridial and oogonial conceptacles appear in the same receptacle. 3. Receptacles originate from a triangular apical cell which in longitudinal sections appears lenticular. 4. In origin and development the conceptacles are like those of Sargassum and most of the other genera and species of the Sargassaceae which have been studied. 5. In the male conceptacle a normal paraphysis develops from the tongue cell, but in the oogonial conceptacles it disintegrates early and gives rise to a mucilaginous substance. 6. The central area of the floor of the conceptacle is sterile and bears a tuft of unbranched paraphyses, as has been observed in a few other genera. 7. The antheridia vary in position from being essentially sessile to being stalked or as branches of filaments. Occasion...

Facies of the coralligenous biocoenose in two stations of the Western and Eastern Mediterranean Basins. — The benthic comunities of circalittoral region have been studied by diving technique in the Western and Eastern Mediterranean Basins. The facies of the coralligenous biocoenose which show a larger difference between the two Basins are: 1) the communities of non calcareous algae in biotopes with constant direction depth streams and 2) the precoralligenous facies. These communities in the Aegean Sea are characterized by Sargassum linifolium, Cystoseira corniculata v. laxior, Caulerpa prolifera, Udotea petiolata, Dasycladus clavaeformis and by sponge Calix nicaeensis; in the Thyrrenean Sea by Laminaria rodriguezii, Cystoseira spinosa, Neurocaulon grandiflorum, Fauchea repens, Halymenia dichotoma, Callymenia reniformis and by the sponge Axinella cannabina. The environmental factors which determine these different facies in the circalittoral region of the two Mediterranean Basins are chiefly the t...

The composition of gas in the vesicles of Sargassum cf. leptopodumSonder has been investigated. The oxygen content depends upon the oxygen partial pressure of the surrounding medium. It does not depend upon the photosynthetic activity of the vesicle. Evidence is provided that the lower limit of the vertical distribution zone of Sargassum cf. leptopodumSonder is not controlled by the vesicles' capability of resisting hydrostatic pressure.

Sargassum hawaiiensis Doty and Newhouse was described in 1966 from a fragmentation specimen dredged from a depth of 50 m off Oahu, Hawaii. Until recently, no further collections have been available for study. In 1968 and 1971 new material was collected from Penguin Banks off Molokai, Hawaii, during shrimp trawling operations by the National Marine Fisheries Service vessel “Townsend Cromwell”. The specimens were obtained from depths of 183 and 200 meters. A complete description of the species is given, which differentiates it from the three other species of Sargassum recognized from Hawaii. Sargassum hawaiiensis is distinguished by a combination of characteristics, these being: simple spines on some branches, terete vesicle petioles, muticous and spherical vesicles and bifurcate receptacles with narrow sterile bridges.

Seaweeds are used many folds for animal and human food, soil manure, salt extractions (soda, iodine etc.) and colloid production (agar-agar, alginate, carrageenan, furcellaran etc.), cosmetics and pharmaceutics. These represent important economical resources in world wide, where they are not only largely harvested but also intensively and largely employed in the human nutrition. Mineral composition of seaweeds was found relatively higher as compared to the land vegetables. Keeping the significance in mind, in current work nine seaweeds such as Chaetomorpha spp., Cladophora facicaularis, Ulva lactuca, Caulerepa racemosa, Caulerepa sertularioides, Valoniopsis pachynema, Sargassum ilicifolium, Sargassum polycustum and Porphyra vietnamensis growing along the Bet Dwarka, West Coast of Gujarat, India were collected and analyzed for nutrient / mineral composition like Mg, K, Na, Ca, S, N, Cl and P, ash content and calorific value. The nutrient concentration ranges found for each sample, were as follows: Mg, 70.4-248.1; K, 16.6-128.04; Na, 78.7-129.07; Ca, 121-476.67; S, 101.11-214.99; N, 34.31-56.34; Cl, 26.12-235.66; and P, 0.78-1.53 expressed in g/100 g dry weight. Calorific content and ash content, ranged between 11.3-22.6 MJ/Kg and 23.0-41.9 g/100 g dry weight, respectively. Calorific content was negatively correlated with ash content and nutrient composition, but ash content was found to be positive correlation with mineral composition of selected sea weeds.

Ecological subdivision of marine organisms is often based on two characteristics: presence in a defined environment, and types of locomotion (degree of free active movement) in such an environment. The use of these characteristics results in a simple scheme: (1) Inhabitants of the boundary surface “ocean-atmosphere” (a zone including not only the surface film but also the thin subsurface water layer below it and the air layer just above it, i.e., pleuston and neuston). (2) Inhabitants of the deeper water layers of the ocean i.e., excluding the zone mentioned under (1): (a) passively drifting forms with very limited locomotory capacity, moving practically in the vertical plane only (plankton); (b) actively moving forms which migrate both vertically and horizontally (nekton). (3) Inhabitants of the “bottom”-benthos (level-bottom of oceans and coastal waters, tidal zones up to the upper supralittoral, different types of drifting and floating substrata, e.g. ship bottoms, harbour structures, buoys, driftwood, sargassum, whales, etc.). This simple scheme is essentially based on characteristics of adults. If developmental stages are considered, pelagic larvae of bottom invertebrates, eggs and larvae of fishes and other forms, usually present only temporarily in the plankton, neuston, and pleuston, can be distinguished as “mero-plankton”, “mero-neuston” and “mero-pleuston”, from the permanent “holo”-components of these groups. Division into “mero”-subgroups opposes all these larvae to those of planktonic, neustonic and pleustonic forms developing within the “parental” groups and their environments. However, the last category of larvae in the light of world-wide distribution of the seasonal reproductive pattern of marine invertebrates and some other organisms — especially in temperate and high latitudes — can also be rated to some degree as “mero”-(not “holo”-) components. The present paper proposes to unite all larvae of marine invertebrates (and of other organisms) undergoing pelagic development into one biological group, the “pelagic larvaton”. The main characteristic for all forms of this group is the presence of one and the same life-cycle stage in one and the same environment. All forms of the “pelagic larvaton” are, to various degrees, biologically different from their respective adult forms. Even the pelagic larvae of the holoplanktonic species exhibit some differences. Within the “pelagic larvaton”, 3 subgroups can be distinguished on the basis of their ecological peculiarities; (1) Larvae undergoing their whole development in an environment different from that inhabited by their parents and belonging to a group different from that of their parental forms; e.g. the pelagic larvae of bottom invertebrates which develop in the plankton, neuston or pleuston. (2) Larvae undergoing development in the same general pelagic environment, but in “non-parental” ecological groups; e.g. larvae of nektonic species developing in the plankton, neuston or pleuston; larvae of planktonic species in the neuston or pleuston; larvae of neustonic and pleustonic species in the plankton. (3) Larvae undergoing development in the “parental” groups; e.g. larvae of planktonic species in the plankton, of neustonic species in the neuston, or of pleustonic species in the pleuston.

Seaweeds populations and secondary vulcanic phenomena off the Vulcan Isle (Tyrrhenian Sea). — In the marine waters off the Vulcan Isle (Tyrrhenian Sea) there are secondary vulcanic phenomena consisting in sulphureous (H2S, SO2, SO3) emanations and in thermal springs. The A. describe relations between these phenomena and benthonical seaweeds populations. Cyanophyceae and Bacillariophyceae endure extreme values of pH (4,5) and temperature (48° C). The characteristic species of these biotopes are be found in earthly thermal Springs too. The vegetation of the neighbourhood is represented by perennial Phaeophyceae and by filamentous Ceramiaceae. Cystoseira ericoides, Cystoseira platyramosa, Sargassum flavifolium are newly found species from southern Tyrrhenian Sea and some Cyanophyceae for the first time are mentioned in marine waters.

During a 24-hr period (12-13 April, 1966) continuous records of temperature, relative humidity, wind speed, wind direction, salt spray, and evaporative power of the air were made at Nungua beach, Ghana. Water loss from emersed plants of Sargassum vulgare, Bryocladia thyrsigera, and Ulva fasciata was measured during the same period. The daily march of desiccation in these seaweeds follows the curve for evaporative power of the air. At night the 3 species lose relatively little water and very nearly the same percentage in each case. During the day Ulva is most resistant to water loss, Bryocladia next, and Sargassum is least resistant. This behavior is correlated with the upper limits of the zones they occupy on the shore.

Marine algae are one of the most important marine living resources for food, feed and medicine since ancient times in the West. However, due to lack of awareness among the people especially in India, their multifunctional properties have not yet been exploited. This paper deals with the pigment composition and its significant variation found in eighteen different species of marine macroalgae belonging to Chlorophyta, Phaeophyta and Rhodophyta, collected from the coast of Okha , Gulf of Kutch , Gujarat, India. Chlorophyll and carotenoids extraction was done with 80% acetone as solvent while phycoerythrin pigment was extracted using 50mM phosphate buffer (pH 7.0). The highest chlorophyll content was registered in Cladophora fascicularis while carotenoid content was found to be the highest in Sargassum polycustum. S imilarly phycoerythrin content was recorded greater in Scinaia farcellata followed by Porphyra necnamessis and Acanthophora delilei Lamour respectively. In terms of chlorophyll content, the maximum chlorophyll a, b as well as total chlorophyll was registered in most of the species of Chlorophyta followed by Phaeophyta and ultimately Rhodophyta. However, carotenoids were registered to be the highest in most of the species of Phaeophyta group . The group wise distribution of carotenoid showed an order: Phaeophyta>Rhodophyta>Chlorophyta. Chl b /Chl a , Car/Chl a and Car/Chl b ratios were also calculated and high ratios were recorded in Liagora erecta, S.polycustum and Padina gymnospora, respectively. Besides, phycoerythrin content showed the following trend in the species of: Rhodophyta>Phaeophyta>Chlorophyta. Emphasis was made to know the variation of different pigments of all eighteen species of marine macroalgae in this paper. Key words: Marine macroalgae, Chlorophyll a, b, Carotenoid, Phycoerythrin.

Fungi inhabiting Sargassum spp. from the Sargasso Sea were examined. Three ascomycetes were found, two of which are new records for this environment. Haloguignardia oceanica (Ferdinandsen et Winge) Kohlm. comb. nov. was collected only once before, over 50 years ago. Haloguignardia tumefaciens (Cribb et Herbert) Cribb et Cribb was known only from Australia and New Zealand. Imperfect states of these ascomycetes and fruiting bodies (acervuli) of a hyperparasitic deuteromycete (cf. Sphaceloma sp.) were found for the first time in the galls of the two species. Lindra thalassiaeOrpurt et al., previously known only from the sea grass Thalassia testudinumKongig, develops in air bladders of Sargassum sp., causing a shedding of infested vesicles. Possible reasons for the rarity of fungal species and diseased plants in the Sargasso Sea are diseussed.

In the Sargassum region on the coast of Mukaishima, in the Inland Sea of Japan, the phytal animals living on Sargassum serratifolium, and the alga itself as a habitat for phytal animals, were studied from August, 1966 to August, 1968. The standing crop of Sargassum/m2 bottom was 4.93 kg/m2 (March, 1967) and 3.53 kg/m2 (February, 1968) in the most luxuriant season, and 0.4 to 0.5 kg/m2 (July, 1967 and 1968) in the off-season. The individual number of phytal animals per mean plant, without sessile fauna, reached a maximum in late winter and early spring (about 130,000 in 1967, 266,000 in 1968) when Sargassum was luxuriant, and a minimum in summer (about 15,000 in both years) when Sargassum was declining. Among the phytal animals, benthonic copepods (Harpacticoida) were very abundant in most seasons. Their dominance decreased in spring, whilst nematode dominance increased. It appears that such seasonal changes are closely related to the standing crop of S. serratifolium. Fluctuations in numbers of most groups of the meiofauna of phytal animals, such as foraminiferans, ostracods, isopods, amphipods, copepods, tanaids and nematodes, are connected with changes in the standing Sargassum crop. Seasonal fluctuations of some groups, such as echinoderms, actinians, mysids and decapod crustaceans (macrofauna), were, however, independent of Sargassum crop variations. The individual number of phytal animals/m2 bottom in the Sargassum region were compared with findings of previous studies in other habitats, such as naked sandy and mud bottoms.

Respiration of the pelagic Sargassum community was determined at three stations along a transect from a Slope Water station off New Jersey to a position southeast of Bermuda. Total community respiration ranged from 9·6 ml O2 g dry wt. Sargassum−1hr−1 in the Sargasso Sea to 13·6 ml O2 g dry wt. Sargassum −1hr−1 at the Slope station. Community respiration was compartmentalized into epiphyte, macrofaunal, Sargassum, and microbial respiration. Microbial respiration was the most important component, contributing from 47 to 54% of the total uptake. Macrofaunal respiration accounted for 18 to 24% of the total community respiration, while Sargassum oxygen consumption contributed from 15 to 20%. Epiphyte respiration was more important in the Slope Water (18%) than in the Sargasso Sea (2–5%). The importance of the Sargassum community in the epipelagic zone is discussed.

Three species of Sargassum with compressed primary branches, S. binderi Sonder, S. oligocystum Montagne and S. swartzii (Turner) C.A. Agardh, have been described from the Gulf of Thailand. S. swartzii is the first record of this species from the coast of Thailand. A key for these three species and for each species descriptions have been completed. The clear distinction among these three species is clearly shown and discussed. S. binderi has slender lanceolate leaves, a dentate margin along the compressed stem of its vesicles, and clear spines along the whole margin of the flattened receptacles. S. oligocystum has broader lanceolate leaves with an acute to rounded apex, almost entire, spherical vesicles, and only few spines on the margin of the slightly compressed receptacles. S. swartzii has linear lanceolate leaves, pointed or crowned vesicles, and few spines neat the tip of its almost terete receptacles.

Ingestion, egestion, growth, and respiration measurements were made in the laboratory on three size-classes of the Sargassum fish, Histrio histrio (L.). Comparison of three size-classes showed changes from high growth and low respiration and assimilation in small Histrio to reduced growth and increased respiration and assimilation in larger fish. A high assimilation and growth efficiency suggest that Histrio is adapted to a food-limited environment (Sargasso Sea). Energy requirements of the smallest size-class (10–29 mm) were compared to the energy provided by their dominant food source, the Sargassum shrimp Latreutes fucorum (Fabricius) and Leander tenuicornis (Say). The annual energy requirement per individual was 1.4 times greater than the food energy available. This discrepancy is attributed to the difficulty in extrapolating laboratory studies to the field and the difficulty in obtaining adequate population size measurements of the Sargassum community fauna.

Thirteen species of diatoms, including two new species, were observed as epiphytes on Sargassum collected at seven locations in the western Sargasso Sea. The most widespread species was Mastogloia binotata (Grun.) C1., being found at all seven locations. Eight species of Mastogloia were observed along with one each of Cyclotella, Cocconeis, Nitzschia, Synedra, and Navicula. In comparison with epiphytic diatoms from inshore and freshwater areas, the number of species of diatoms on floating Sargassum is relatively low.

In the present paper deals with the estimation of the free amino acid composition of Ulva pertusa, Enteromorpha linza (green algae), Undaria pinnatifida, Sargassum confusum (brown algae), and Chondria crassicaulis, Neodilsea yendoana, Laurencia nipponica (red algae) using an amino acid analyzer (Hitachi, type KLA-III, Amberlite CG 120). The results obtained are shown in Table 2. Amino acid composition of Ulva is in good agreement with that of Enteromorpha in rich amount of D-cysteinolic acid and less amount of taurine, tyrosine, tryptophan, arginine, and lysine. None of alloisoleucine, citrulline, histidine, methionine, ornithine, and S-hydroxy-methyl-L-homocysteine are found in these two species. High contents of alanine, glycine and proline in Undaria, those of alanine in Sargassum, chondrine in Chondria, taurine in Neodilsea, and glutamic acid and valine in Laurencia are specifically recognized. A few amount of alloisoleucine is found in Undaria, whereas chondrine observed in every species of these algae. Citrulline is present only in Neodilsea, ornithine in Sargassum, Neodilsea, and Laurencia. S-Hydroxymethyl-L-homocysteine is found in Neodilsea and Laurencia in appreciable amounts, but D-cysteinolic acid is not detected in these algae. The presence of some unknown compounds is suggested from the present study.

Pelagic Sargassum weed and associated macrofauna were analyzed for their hydrocarbon content. All the organisms appeared contaminated with petroleum hydrocarbons. There was no relation between the amount of natural, recently biosynthesized hydrocarbons in an organism and the amount of petroleum contamination. Animals had a larger ratio of petroleum to natural compounds than the Sargassum. There was no relation between the hydrocarbon content and the animals' supposed positions in the food chain.

Summary From culture experiments it has been shown that the early stages in the development of Halidrys siliquosa are more similar to those of Cystoseira and Sargassum than to those of Fucus. The young plant has cryptoblasts along the primary frond and these are absent from the adult thallus. These hair pits are associated with the development of apical cells and the definitive axis of the adult thallus. The first year's growth is entirely vegetative and results in a pinnately branched thallus of ‘leafy laterals’only. Air vesicles are differentiated during the second year's growth and fertile receptacles are formed later. The receptacles are initiated from the end of August and new ones continue to be formed until December. Gametes are differentiated shortly before their discharge from December till March. After gamete discharge the receptacles disintegrate. The adult thallus shows a seasonal periodicity in growth and reproduction. There is a period of rapid vegetative growth during the spring and early summer which is followed by receptacle differentiation and-then gamete discharge from December to March.

In a previous work ?? the authors observed that fucosterol isolated from brown algae could slightly reduce liver cholestrol in rats but almost no effect against their plasma cholesterol. In 1962 Reiner and his co-workers reported that fucosterol caused a significant diminution in plasma cholesterol level of young Leghorn cockerels. Using rats, the authors re-examined the effect of fucosterol on cholesterol metabolism. In this experiment, check was also made for the effects of unsaponifiable fraction and of methyl ester of fatty acids isolated from Sargassum ringoldianum. Rats were fed ad lib. for 16 days a diet containing fucosterol, fucosterol-free unsaponifiable matter of Sargassum lipids or methyl ester of the fatty acids separated from the same algae. Exogenous (1%) cholesterol was added to each group of the diet. As shown in Table 3, fucosterol and other unsaponifiable matter could reduce slightly plasma and liver cholesterol. However, the effect of these substances was lower than β-sitosterol used as control. Methyl ester of fatty acids showed no effect. The differences of the effects between the present results and Reiners' are probably originated from the difference of animals used for the tests.

Five species of marine a1gae were collected from Saint Martin’s island, identified and biochemical analyses were carried out in BCSIR Laboratories, Chittagong. Biochemical composition were analysed to evaluate its food value and also to find out variation in composition during the period of investigation. The protein content of Sargassum coriifolium was 16.07%, whereas in Padina ltenuis that was estimated at 8.32%. The percentage of fat in Sargassuni coriitolium along with the other sea weeds was 0.5%. It was found that major of the biochemical parameters of these sea weeds were higher except the protein contents than that of Spirulina . The carbohydrate content in Dictyota dichotoma (38.94%) was lower among these sea weeds, but more than that of Spirulina . Carbohydrate contents were higher (56.29%) in Hypnea musciformis . Mineral contents as well as other parameters, especially carbohydrate contents were higher in these algae than that of Spirulina .

The osmotic value of some algae was determined in 1928 under the direction of Professor Kiichi MIYAKE, of the Tokyo Imperial University, by observing plasmolysis of the cells due to varius solutions. The results are summarized as follows: - (1) Fresh-water (Spirogyra and Cldaohora) as well as marine algae (Chaetomorpha, Sargassum, Euchuma, etc.) were used as given in Table 1. (2) The solutions of cane sugar and of sodium chloride were used as the reagents for determining the osmotic values. (3) The osmotic value is by far higher in the marine algae than in the fresh-water ones, but that of surrounding media, in which either group of algae grow, is much less than that of the aquatic platns respectively. (4) The value in question is nearly the same in the marine algae growing in the same zone, that for the plants in sublittoral zone being higher than that for the littoral algae. See Table 1. (5) The osmotic value is not the same in the entire many-layered algal body, that for the outer cell-layers being higher than that for the inner ones, as shown in Table 2.

Pursuant to the idea that pedunculate brachiopods do not necessarily require a hard substratum for attachment, it is postulated that brachiopods may attach themselves to floating seaweed of the Sargassum type and as a result may be found in sediments out of keeping with their normal habitat. Occurrences of rhynchonelloids substantiating this theory are cited from the literature.
