Fatty acid profile of Cystoseira C. Agardh (Phaeophyceae, Fucales) species from the Tunisian coast: Taxonomic and nutritional assessments

“…Una gran diversidad de Cystoseira está presente en la costa de Túnez. De acuerdo con Bouafif et al (2014Bouafif et al ( , 2016, hay 31 especies sobre el litoral de Túnez, pero existe poca información publicada sobre la composición química de las algas de esta región (Frikha et al 2011). Además, es difícil distinguir entre las especies y variedades de Cystoseira debido, principalmente, a la alta plasticidad morfológica de los taxones y al proceso activo de especiación del género (Ercegovič 1952, Amico 1995.…”

“…El propósito de este trabajo es determinar la composición de los AG extraídos de 11 especies del género Cystoseira (Fig. 1) que crecen a lo largo de la costa de Túnez para (i) evaluar la eficacia de los AG de Cystoseira como marcadores quimiotaxonómicos asociados a criterios aplicados a la diversidad morfológica de los taxones de Cystoseira de Túnez (Bouafif et al 2014(Bouafif et al , 2016) y (ii) estimar las características nutricionales de una de las algas pardas que más abunda en el mar Mediterráneo. Hasta donde sabemos, este es el primer estudio del perfil de los AG de algunas especies de Cystoseira endémicas del mar Mediterráneo.…”

“…The aim of this paper is to assess the composition of FAs extracted from 11 Cystoseira species (Fig. 1) growing along the Tunisian coast (i) to evaluate the efficiency of Cystoseira FAs as chemotaxonomic markers associated with criteria performed on the morphological diversity of Tunisian Cystoseira taxa (Bouafif et al 2014(Bouafif et al , 2016 and (ii) to estimate the nutritional characteristics of one of the most abundantly available brown macroalgae in the Mediterranean. To the best of our knowledge, this is the first report on the FA profile of some endemic Mediterranean species of Cystoseira.…”

Cystoseira montagneiJ. Agardh andC. spinosaSauvageau (Phaeophyceae, Sargassaceae): A Taxonomic Reappraisal of Misused Names, with the Proposal ofCystoseira michaelaeVerlaqueet al.nom. et stat. nov.

“…Out of 289 taxa of Cystoseira listed worldwide (including homotypic and heterotypic synonyms and names of uncertain taxonomic status), 32 species and more than fifteen infra-specific taxa are currently accepted taxonomically in the Mediterranean Sea (Guiry & Guiry, 2017). However, in spite of their importance as habitat formers, the delimitation and distribution of a number of species are still not well known (Roberts, 1978;Ribera et al 1992, Draisma et al, 2010Cormaci et al, 2012;Berov et al, 2015;Bouafif et al, 2014Bouafif et al, , 2016. The reason for this is that the species of Cystoseira offer few unambiguous diagnostic characters and that some of these characters are more or less overlapping.…”
