Aproximación al análisis fitosociológico de la flora algal del subestrato de Cystoseira mediterranea Sauv., en el litoral valenciano (España, Mediterráneo)
Se analiza fitosociológicamente la flora que coloniza el subestrato de (Sys/oseira mediterranea Sauv. en la costa valenciana. Los resultados concuerdan, en líneas generales, con los obíenidos en otros puntos del Mediterráneo occidental, destacando la abundancia de especies fotófilas y de amplia valencia ecológica.A phytosociological studv of the flora that grows under the canopy of (ysíoseira mediterranea Sauv. in the Levantine coast of Spain (Mediterranean) is made. The results are in agreement with other ones from other sites of Western Me diterranean basin. The infralittoral photophilous species are the more conspicuous group

Intraindividual Variation in Nuclear DNA Content in Durvillaea Antarctica (Chamisso) Hariot, Macrocystis pyrifera (Linnaeus) C. Agardh and Lessonia spicata (Suhr) Santelices (Phaeophyceae)
Macrocystis C. Agardh, Durvillaea Bory and Lessonia Bory are three brown seaweeds genera of commercial importance for Chilean fishermen. Macrocystis pyrifera (Linnaeus) C. Agardh (Laminariales, Laminariaceae) is one of the world's most ecologically and economically important seaweed collected in Chile for alginate extraction; and as food for abalone aquaculture, Lessonia spicata (Suhr) Santelices (Laminariales, Lessoniaceae) represents more than 70% of the total brown seaweeds annual landing in Chile; and Durvillaea antarctica (Chamisso) Hariot (Fucales, Durvillaeaceae) is consumed as food, being considered very healthy because of its iodine content. Despite the economic importance of these species their nuclear DNA content is unknown until this moment. The present research was initiated to determine the nuclear DNA content and the intraindividual ploidy level variation in these seaweeds. The DNA-localizing fluorochrome DAPI (4',6-diamidino-2-phenylindole) and red blood cell (chicken erythrocyte) standard were used to estimate the nuclear DNA contents by image analysis. Durvillaea antarctica presented lower 2C DNA (1.2 pg) content and narrower range of DNA contents (1C-2C) than the Laminariales, which showed higher 2C DNA contents (1.4 -1.5 pg) and a wider range of ploidy level, achieving up to 4C in L. spicata and up to 8C in M. pyrifera. This higher ploidy levels observed would be related with the more complex cortical organization in the Laminariales than D. antarctica. 1C nuclei were only found in mature antheridia (D. antarctica) and sporangia (M. pyrifera and L. spicata). The 2C values observed for the taxa assessed were in the range of other previously published Fucales and Laminariales
Addicions a la flora algològica del Principat de Catalunya
In a sandy-bed near Arenys de Mar (Barcelona, Spain) some algal species were collected, using scuba-diving techniques, at 25-32 m depth. Three of them were for the first time found in the catalan coast: Halymenia latifolia Crouan & Crouan, Halymenia floresia (Clemente) C. Agardh var. pinnata Codomier and Carpomitra costata (Stackhouse) Batters var. mediterranea Feldmann

Catálogo de las macroalgas bénticas marinas de Argelia, parte II: Ulvophyceae
The seaweed diversity of the Mediterranean is still not completely known, especially in some areas of its African coasts. As an effort to complete a more detailed catalogue to fill such gap, an updated checklist of seaweeds from Algeria, based on updated literature records, is developed using as starting point the checklist of Perret-Boudouresque and Seridi published in 1989. In the present work, in which we include the Ulvophyceae Mattox & K.D.Stewart, we list 73 accepted taxa from this group, among which there are 8 new records for Algeria.The seaweed diversity of the Mediterranean is still not completely known, especially in some areas of its African coasts.
