Lista de algas marinas del Parque Nacional de Alhucemas en Marruecos (Área Marina Protegida del Mediterráneo)

The Mediterranean basin is a marine biodiversity hot spot. Despite this, the macroalgal diversity of the Mediterranean Sea is still not fully known, especially in the Mediterranean Marine Protected Areas (MPAs) including, Al-Hoceima National Park of Morocco (PNAH). This paper provides the first comprehensive checklist of the seaweeds of PNAH, based chiefly on our own original collections, and complimented by literature records. Using present-day taxonomy, the total number of taxa at both specific and infraspecific levels currently accepted is 306 taxa with 207 Rhodophyta (39 families), 51 Ochrophyta (13 families) and 48 Chlorophyta (12 families). Ninety five of these species were not found in our samples, 93 were new to the PNAH, and the taxonomic identity of 26 taxa was amended. From the totality of taxa, ten species were reported for the first time from Morocco: 9 Rhodophyta and one green alga. Furthermore, 12 others species (10 red, 1 brown and 1 green alga) are new records for the Mediterranean coast of Morocco. Besides this, confirmed records are mentioned for 20 species, whether in Africa, in Morocco or in the Moroccan Mediterranean coast. This accessible checklist to the international community could serve as an infrastructure for future algal investigations of the taxa in this Specially Protected Area of Mediterranean Importance

Checklist of seaweeds of Al-Hoceima National Park of Morocco (Mediterranean Marine Protected Area)

Abstract The Mediterranean basin is a marine biodiversity hot spot. Despite this, the macroalgal diversity of the Mediterranean Sea is still not fully known, especially in the Mediterranean Marine Protected Areas (MPAs) including, Al-Hoceima National Park of Morocco (PNAH).

Using present-day taxonomy, the total number of taxa at both specific and infraspecific levels currently accepted   is 306 taxa with 207 Rhodophyta (39 families), 51 Ochrophyta (13 families) and 48 Chlorophyta (12 families).

Aún así, la diversidad de macroalgas del Mediterráneo no está plenamente conocida, especialmente en las Áreas Marinas Protegidas del Mediterráneo (AMP) incluido el Parque Nacional de Alhucemas en Marruecos (PNAH). Este documento proporciona la primera lista exhaustiva de las algas marinas del PNAH. Usando la taxonomía actual, el número total de taxones a niveles específicos y infraespecíficos actualmente aceptados es de 306 taxones con 207 Rhodophyta (39 familias), 51 Ochrophyta (13 familias) y 48 Chlorophyta (12 familias). Noventa y cinco de estas especies no se encontraron en nuestras muestras, 93 eran nuevas en el PNAH y se modificó la identidad taxonómica de 26 taxones. De la totalidad de las macroalgas, 10 especies (9 Rhodophyta y 1 Ulvophyceae) fueron registradas por primera vez desde Marruecos. Además, 12 otras especies (10 Rhodophyta, 1 Phaeophyceae y 1 Ulvophyceae) son nuevos registros para la costa mediterránea de Marruecos. También, se mencionan los registros confirmados de 20 especies, ya sea en África, en Marruecos o en la costa mediterránea marroquí. Esta lista de algas accesibles a la comunidad internacional podría servir como una infraestructura para futuras investigaciones algales de los taxones en esta zona especialmente protegida de importancia para el Mediterráneo. Palabras clave: Parque Nacional de Alhucemas, Lista de algas, Áreas Marinas Protegidas del Mediterráneo, Marruecos, Algas marinas.

New records of benthic marine algae from Morocco (eastern Atlantic Ocean): morphology, taxonomy and distribution

AbstractWe report new records and corological data for three Moroccan marine macroalgae that complete their distribution information. Radicilingua thysanorhizans is new record for Morocco; Champia compressa is recorded for the first time from the eastern coast of the Atlantic Ocean. Diplothamnion jolyi is widely distributed in the western coast of the Atlantic coast and Pacific Islands, and recently reported from the Mediterranean Sea; this new record from Moroccan Atlantic coast extends their distribution range.Key words: Algae, Atlantic Ocean, Champia compressa, Diplothamnion jolyi, Radicilingua thysanorhizans.ResumenSe aportan nuevos registros y datos corológicos para tres macroalgas marinas de Marruecos, que completan la información sobre su distribución. Radicilingua thysanorhizans es cita nueva para Marruecos. Champia compressa se registra por la primera vez en la costa oriental del Océano Atlántico. Diplothamnion jolyi se distribuye ampliamente en la costa occidental de la costa atlántica y las islas del Pacífico y ha sido recientemente citada en el mar Mediterráneo; esta nueva cita para costa Atlántica Marroquí amplia su rango de distribución.Palabras clave: Algae, Océano Atlántico, Champia compressa, Diplothamnion jolyi, Radicilingua thysanorhizans

Insights on the anti-inflammatory and antitumor activities of extracts from the marine green alga Codium decorticatum

Introduction: The Codium genus has been shown to be an important source of marine bioactive compounds for pharmaceutical and nutraceutical applications. The present study was conducted to investigate the anti-inflammatory activity of the n-hexane (Extr 1), dichloromethane (Extr 2) and acetone/methanol (Extr 3) extracts of the green alga Codium decorticatum, as well as their antitumor effects on several cancer cell lines. Methods: In order to evaluate the anti-inflammatory effect of the extracts of C. decorticatum on the production of the pro-inflammatory proteins, we have undertaken analyses of LPSand TNF-alpha-stimulated endothelial cells treated with extracts using enzyme-linked immunosorbent assay (ELISA). Real-time PCR (qPCR) was used to modulate the mRNA expression of inflammatory genes. For the antitumor activity, in vitro cytotoxicity was determined by MTT assay and apoptosis was determined by flow cytometry. Results: Our results revealed that the Extr 2 and Extr 3 dramatically inhibited the expression of the pro -inflammatory cytokine Interleukin-8 (IL-8) in LPSand TNF-alpha-stimulated endothelial cells. We also demonstrated that Extr 2 suppressed the LPS-induced mRNA expression of E-selectin and IL-8. Furthermore, Extr 2 showed cytotoxic activity against the HeLa cell line (IC50 = 37.22 mu g/mL), by inducing apoptosis at highest concentrations. Conclusions: The present data suggest that the seaweed C. decorticatum has the anti-inflammatory properties in endothelial cells, together with the anticancer effect on cervix cancer cells, which may have a potential therapeutic use for inflammatory diseases and cancer. Although, its application as nutraceuticals and functional food could be also considered.L'Oreal-UNESCO for Women in Science Maghreb Fellowships, 2017/2018EU-METALIC II Erasmus Mundus projectinfo:eu-repo/semantics/publishedVersio
