Mapeo indirecto de la vegetación de Sierra de la Ventana, provincia de Buenos Aires
Provedor de dados: 67
Autores: Lizzi,José M; Garbulsky,Martín F; Golluscio,Rodolfo A; Deregibus,Alejandro V.
La cartografía de la vegetación permite conocer la extensión y distribución espacial de sus unidades y constituye una herramienta imprescindible para planificar la conservación y utilización de los recursos. Si bien los pastizales de la provincia de Buenos Aires han sido extensamente estudiados, aún no se cuenta con cartografía de la vegetación regional de Sierra de la Ventana con un detalle adecuado a su heterogeneidad. Una de las causas de esa carencia es que los sitios de topografía compleja dificultan los mapeos de vegetación mediante técnicas convencionales de foto-interpretación o clasificación de imágenes satelitales. En este trabajo se aplicaron técnicas de mapeo indirecto de la vegetación para cartografiar la vegetación potencial de la región. La...

Microflore et anchoitage.
Provedor de dados: 5
Autores: Campello, Francois.
The author studies the microbial phenomena which occur during the maturation of French anchovies, some from the Basque, the others from the Roussillon coast. There are some differences in relation with the origin of the fishes. On a marine agar, the microflora of the Mediterranean ones is almost constant or in a light diminution while that of the Atlantic ones is climbing during 9 weeks before a decline. On an extremely salted agar and in the both origins the archaebacteria are increasing in number during 5 to 6 weeks and diminishing before. The complete ripening is obtained within 16-17 weeks. The limits of the significance of the microbiological analysis are discussed.

Autores: Borgne-david, A. Le.
20 samples of phytoplankton were collected by the 'Thalassa' on the Libyan and east Tunisian coast, from Nov 13th to 29th 1969. The vegetal plankton is rather poor on the whole, except in the Gulf of Gabes. Diatoms are dominant and Rhizosolenia plays a leading part. Among the Dinophyceae, the great variety of Ceratium underlines the subtropical affinities of the study area.

Disease problems in farmed penaeids in Italy
Provedor de dados: 5
Autores: Giorgetti, G.
The industrial farming of penaeid shrimps began in Italy in the early eighties with the introduction of Penaeus japonicus , that replaced Penaeus kerathurus . In Italy there are no farms for producing eggs and fry on a commercial basis, the restocking material is usually imported from abroad at the stage of post-larval 22-25. Various pathologies were found that appeared to be connected with husbandry techniques, such as overfeeding with low water exchange, overcrowding and poor water quality. Our laboratory diagnosed diseases caused by: virus: infectious pancreatic necrosis (IPN) virus was isolated on EPC-RTG2 cells from spawners without apparent mortality; bacteria: the most frequently isolated bacterium was Vibrio anguillarum , on TSA, marine agar and...

The vicinity of the Strait of Gibraltrar: A source of a permanent high productivity
Provedor de dados: 5
Autores: Minas, H; Coste, B; Minas, M.
Satellite infrared imagery shows that a cooling of the sea furface occurs in the Strait of Gibraltar and along the Spanish coast in the Alboran Sea. Since this cooling has an internal origin, it implicates also a nutrient transport into the photic zone. A high chlorophyll area off the Spanish coast, also shown by ocean color imagery (CZCS, Nimbus 7) demonstrate a high productivity. Hydrological and chemical observations made during the French "MEDIPROD IV" cruise on the Jean-Charcot allow to explain this high productivity. The high productivity entertains at mid-depth, by organic sedimentation, an oxygen minimum layer which corresponds to a nutrient maximum (phosphate and nitrate). This high biological activity is useful for hydrological purposes since the...

A field report on vibrio disease of seabass (Dicentrarchus labrax ) in the South of France
Provedor de dados: 5
Autores: Breuil, Gilles; Haffner, Philippe.
Vibrio anguillarum was isolated from diseased seabass reared in aquatic farms (hatcheries and grow-out farms) located along the French Mediterranean coast. A representative strain (V62) differs from the French V. anguillarum strain (V408) by its ability to grow on a 0% salinity medium. The pathogenicity of the representative strain for sea bass was confirmed by injections and bath challenge. The V62 strain reacted with V. anguillarum antiserum (V408) and 84% of the isolated strains from diseased sea bass agglutinated with anti V62 serum.

Relationships between age, growth, diet and environmental parameters for anchovy (Engraulis encrasicolus L.) in the Bay of Benisaf (SW Mediterranean, west Algerian coast)
Provedor de dados: 5
Autores: Bacha, Mahmoud; Moali, Aissa; Benmansour, Nasr-eddine; Brylinski, Jean-michel; Mahe, Kelig; Amara, Rachid.
Age, growth and diet of anchovy were studied for the first time from samples collected in the Bay of Benisaf (west Algerian coast) during summer (spawning period) and autumn (recruitment period) 2007. Age structure and growth parameters were determined by otolith (sagitta) analyses. The von Bertalanffy growth function fitted to age-length data showed that most of anchovy growth is achieved during the first year of life, suggesting that this stock is primarily supported by the smallest age groups and has a strong dependence on recruitment. There were no significant differences between males and females, and pooled mean parameters were: L infinity = 15.61 cm, k = 0.75 per year and to, -1.32 years. Whatever the age-class anchovy is strictly zooplanktivorous....

Provedor de dados: 5
Autores: Loubes, Claude; Maurand, Jean; Comps, Michel; Campillo, Albert.
The sporogony of A. nelsoni is of the apansporoblastic type. Diplocaryons always occur during merogony, never occur during sporogony. Sporoblasts are produced by fission of a multinucleate and elongated plasmodium. Spore morphogenesis begins before the end of the end of the sporoblasts individualization. The polaroplast has a very dense outer area. The genus Ameson is very much like genus Perezia and both are badly classified respectively in the families Nosematidae and Unikaryonidae. The creation of the new family Pereziidae is proposed for both genera.

Approche microbiologique de l'anchoitage.
Provedor de dados: 5
Autores: Campello, Francois.
The maturation of salted anchovies leads to a product of particular organoleptic properties. The manufacturers have to resolve many problems. A thorough investigation of the phenomenons which occur is necessary to resolve them. The maturation is conducted at different temperatures. The present paper reports the microbiological variations of the present microfloras, from hyper-halophilic to the non-halophilic, which escort organoleptical and biochemical ones chiefly at 20 degree C. If the maturation's temperature is maintained high (28 degree C) there is a strong proteolysis. At 20 degree C the organoleptical characters appear within 2 months.

Penaeid pathology in Israel: Problems and research
Provedor de dados: 5
Autores: Colorni, A.
A comparative search for the shrimp most suitable for mariculture in Israel has led to the import of exotic species. Unfortunately, these shrimp were carriers of at least three pathogenic viruses. Infectious Hypodermal and Hematopoietic Necrosis (IHHN) virus, Hepatopancreatic Parvo-like Virus (HPV) and Monodon-type Baculovirus (MBV) caused cross-infections among both imported and local penaeids. Since these episodes, general disinfection operations were carried out and quarantine measures were strictly enforced for any newcomers.

Contamination of Delphinidae's fetuses and newborn has been determined from the organochlorine levels found in the fetuses and pregnant female organs, and in the milk of lactating females, for 4 dolphins and 3 porpoises. High levels of these components show an important transference of mother's contamination to their fetuses and new-born. The examination of 69 ulcerative cutaneous lesions allowed to determine 5 main types of ulcerations with pyocytary necrosis and granulomatous reaction.

Autores: Oliver, Guy; Pichot, Yves; Pichot, Paul.
The authors study two populations of Serranus cabrilla, one with a yellow color, the other with a deeper color (orange and brown). They try to see if it is eventually possible to join this duality of coloring to a biochemical difference by the electrophoresis of the eye lens proteins. This technique can give useful indications in a taxonomic study. The results of this work could indicate that the species Serranus cabrilla presents two populations which are separating and tending to a specific individualization. This speciation, perhaps, will tend to the individualization of two species that will be named : Serranus cabrilla for the "red combers" and "Serranus flavus for the "yellow combers".

Biologie du copepode Lernaeenicus sprattae Sowerby, 1806) et ses actions pathogenes sur les populations de sardines des cotes du  Languedoc-Roussillon.
Provedor de dados: 5
Autores: El Gharbi, Salwa; Rousset, Viviane; Raibaut, André.
Lernaeenicus sprattae is a blood-feeding copepod parasite of the pilchard, Sardian pilchardus . The larval stages of L. sprattae attach to the skin or the fins of the larval fish when the fish enter the lagoons. The mature, and in some cases ovigerous females of L.sprattae seek out the base of the fins or directly implant in the eye of juvenile or adult pilchards. The copepod has a particularly serious  effect at the site of infection: its feeding has a severe effect on the fish. The pilchard returns to its breeding grounds in the open sea at the end of summer; this migration allows the copepod to complete its reproductive cycle and a new cycle of infestation is able to begin.

Summer phytoplankton in the Levant Sea, biomass and limiting factors
Provedor de dados: 5
Autores: Berland, B; Burlakova, Z; Georgieva, L; Izmestieva, M; Kholodov, V; Krupatkina, D; Maestrini, S; Zaika, V.
Phytoplankton biomass has been studied in the Levant Sea (Eastern Mediterranean) during summer 1983 in order to picture its vertical distribution as well as its limitation mechanisms. Biological tests carried out on the natural populations of the Basin show that P is the first biomass-limiting element and that N is the second. The simultaneous input of P and N, however, is not sufficient to induce growth; this suggests that Mn has an essential role in the phytoplanktonic growth in this ultra-oligotrophic water. Discussion deals with the significance of the deep chlorophyll a maximum and with the physiological processes allowing it to last.

Pisciculture marine et environnement en France: specificite par rapport a l'eau douce

French marine fish farming deals with several species: sea bass, sea bream, turbot, trout and salmon. In 1992, 20 M fingerlings and 2600 t of fish were produced, for a turnover of 165 MFF: This very technical activity is developing, but still fragile and risky. Environment protection regulation applied to marine fish farming directly inspires from that in force in fresh water, which comes from the industry: i.e. the so-called "classified installation" regulation, concerning activities likely to produce polluting effluents. It does not really adapt to diluted effluents, like fish growing ones, and still less to marine farming; this is true for parameters like biological oxygen demand (BOD) and chemical oxygen demand (COB) and, to a lesser extent, for...

Provedor de dados: 5
Autores: Dosdat, Antoine; Kempf, Marc; Merceron, Michel; Paquotte, Philippe.
Aquaculture in France is characterised by great species diversity. Furthermore, traditional activities (farming of marine shellfish and freshwater fish) coexist with still-developing recent ones (marine fish farming, new pratices in shellfish rearing, etc.). Traditional cultures are the main contributors to the tonnage produced and employment generated. Another noticeable point is the importance of the western part of the country, which carries the main part of the production (&gt; 80 %): the Channel Atlantic coast for shellfish, and nearby rivers for freshwater salmonid farming. On the Mediterranean coast, marine fish farming of bass and bream, as well as shellfish production by new methods (mussels on longlines in open waters), are developing. Important...

The determination of Mediterranean Salmonidae has been possible because of morphological and morphometrical studies and immunological and biochemical methods. It is evident that the 'sea trouts' belong to the species S. trutta fario and S. gairdneri irideus. These trouts have been acclimatized naturally to marine life. Experimental tests were undertaken in the laboratory, then in natural medium, to study the possibilities of trout acclimatization in sea water. They have confirmed the great adaptation qualities of these fishes to often extreme conditions. In the experiments undertaken in variable conditions, the influence of temperature and oxygen were exactly specified. Following these experiments, and other experiments realized in France and in other...

Reduction du nitrate dans les sediments marins. Comparaison des activites mesurees in vitro et in situ
Provedor de dados: 5
Autores: Esteves, J; Bonin, P; Blanc, F; Mille, G; Bertrand, J.
In vitro nitrate reduction in hydrocarbon-polluted marine sediments has been studied by flow-through system. By analysing the rate of nitrate comsumption as a function of nitrate concentration the authors determined the Michaelis-Menten kinetics parameters. (km = 330 mu M; vax = 2.0 mu M/g super(-1)/h super(-1). The authors found a value of 60 mu M/m super(-2)/h super(-1) for the rate of in vitro nitrate consumption derived from the above kinetic parameters and from the nitrate concentration in the sediment. In parallel a value of 67.4 mu M/m super(-2)/h super(-1) was found for the rate of nitrate consumption under in situ conditions. The great similarity between both results would favor the in vitro technique as a valid and more convenient one.

Symphodus (Crenilabrus) ocellatus of the Tunisian southern Gabes coasts feeds on the small bentic invertebrates of shallow medowe bed. The preferential preys of this Labridae fish are crustaceans and mollusces. Trophic variations of this fish by seasons show its specific adaptive response to changes in environment.

&lt;i&gt;Monocelis longistyla&lt;/i&gt; sp.n. from littoral sandy habitats of the Mediterranean is described. The karyotypes of &lt;i&gt;Monocelis fusca, M. lineata&lt;/i&gt; and &lt;i&gt;M. longistyla&lt;/i&gt; sp.n. were analysed. A basic karyotype for the genus Monocelis is postulated and its probable evolution from the basic karyotype of the family Monocelididae and within the genus is discussed. The karyotype of &lt;i&gt;M. longistyla&lt;/i&gt; seems to have evolved from the basic Monocelis karyotype by pericentric inversions. However from the analysis of the karyotype in different populations of &lt;i&gt;M. lineata&lt;/i&gt; the species appeared not to be homogeneous (European populations versus the Canadian population).
