AbstractThe 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. Keywords. Algerian coast, checklist, green algae, seaweeds, Ulvophyceae. |
ResumenEl conocimiento de la diversidad de las algas marinas del Mediterráneo presenta todavía ciertas lagunas, especialmente en algunas áreas de la costa africana. Para completar su catálogo, se está llevando a cabo una revisión crítica y una puesta al día de la flora de algas marinas de Argelia mediante la recopilación y actualización de todas las citas publicadas, tomando como punto de partida la de Perret-Boudouresque y Seridi publicada en 1989. En el presente trabajo, en el que tratamos las Ulvophyceae Mattox & K.D.Stewart, catalogamos un total de 73 táxones aceptados de este grupo, entre los que se encuentran 8 nuevas citas para Argelia. Palabras clave. Algas marinas, algas verdes, catálogo, costa argelina, Ulvophyceae. |

The seaweeds of the Algerian coast have been well studied by classical French phycologists (Montagne 1838, 1846–1849, 1856; Debray 1893, 1897; and several contributions carried out by J. Feldman and G. Feldman-Mazoyer between 1931 and 1961, listed in Perret-Boudouresque & Seridi 1989). Perret-Boudouresque & Seridi (1989) published a checklist of the benthic marine macroalgae which compiled the information on this area up to that moment. In 1993, a taxonomical and nomenclatural critical revision of all the Mediterranean green seaweeds (Ulvophyceae Mattox & K.D.Stewart) was carried out (Gallardo & al. 1993), and concerning the Algerian flora, the article by Perret-Boudouresque & Seridi (1989) was used as a reference. In the two last decades, some authors have continued working on the marine flora of Algeria (Ould-Ahmed & al. 1995; Ould-Ahmed & Meinesz 1998, 2007; Ould-Ahmed 2005; Seridi & al. 2007). Ould-Ahmed & al. (2013) published the first part of the checklist of Algeria corresponding to the Phaeophyceae Kjellm. In addition, there is more information which is often difficult to consult, since it is mostly included in unpublished papers, such as PhD theses (Seridi 1990, 2007; Kadari-Méziane 1994; Ould-Ahmed 1994, 2015). Báez & al. (2004, 2005a, 2005b) used the data of the Algerian species of Cladophora Kütz. compiled in Gallardo & al. (1993) to carry out a geographical analysis of species richness in the Mediterranean Sea, without new data. The aim of this work is to update the knowledge of the green seaweeds inhabiting the Algeria shores.
The list has been compiled following the scheme used in the first part of this series (Ould-Ahmed & al. 2013). All green algal taxa reported in the literature from Algeria have been searched, critically revised and treated according to current rules of taxonomy and nomenclature in order to compile an updated list of the Algerian Ulvophyceae. Taxonomy and nomenclature follow Guiry & Guiry (2019) and, in some cases, Cormaci & al. (2014). In the catalogue, orders, genera and species were arranged alphabetically. When a taxon has been recorded under a synonym, this name is cited after the reference. For information included in unpublished works, locations are indicated after the authors’ citations (Fig. 1). For each taxon the phytogeographic group is annotated according to Cormaci & al. (1982), Giaccone & al (1985), Furnari & al. (2003) and Guiry & Guiry (2019): A = Atlantic; Ab = Boreo-Atlantic; Abt = Boreo-tropical Atlantic; AP = Atlanto-Pacific; At = Atlantic tropical; C = Cosmopolitan; CB = Circumboreal; IA = Indo-Atlantic; IP = Indo-Pacific; M = Mediterranean; P = Pantropical; SC = Sub-cosmopolitan. For several species, comments on taxonomic or misidentifications are included. A list of excluded taxa is also given.

Perret-Boudouresque & Seridi (1989) – Kadari-Méziane (1994): Tipaza, Bou-Ismail – Seridi & al. (2007) – Ould-Ahmed (2015): Tipaza, Cherchell, Chenoua, Ain Tagourait, Anse de Kouali, Bou-Ismail; Alger, Sidi-Fredj, Ain Benian; Boumerdès, Boudouaou; Bejaia, Gouraya; Jijel, Taza).
In the Mediterranean marine benthic flora, Cormaci & al. (2014) included this species in taxa excludenda.
The present checklist encompasses 73 accepted green algal taxa registered to date in Algeria, and two taxa are considered as taxa excludenda. The best represented genera have been Cladophora (13 species), Ulva L. (8 species), Bryopsis J.V.Lamour. (8 species) and Codium Stackh. (7 species). The number of Ulvophyceae registered on the Algerian coasts is low in comparison with its total number for the entire Mediterranean Sea (176 taxa) (Cormaci & al. 2014), or for the Adriatic Sea (134 taxa) (Antolic & al. 2001). However, it is similar to other Mediterranean countries such as Greece (95 taxa) (Tsiamis & al. 2014) and Tunisia (71 taxa) (Guiry & Guiry 2019), and higher than Libya (31 taxa) (Guiry & Guiry 2019).
The current catalogue added eight new records to the included in Perret-Boudouresque & Seridi (1989). Codium fragile and Caulerpa cylindracea are species included in the list of introduced species of the Mediterranean Sea (Zenetos & al. 2010, 2012). The former is a species originate from the northwestern Pacific and at present with a cosmopolitan distribution. Seridi (1990) cited this species for the first time in Algeria, but later has been cited frequently by other authors. Caulerpa cylindracea is a species introduced from western Australia (Silva & al. 1996) and in expansion in the Mediterranean Sea. Actually, this species is cited in all the Mediterranean area and in the Atlantic, Pacific and Indic Oceans (Guiry & Guiry 2019). It was cited for the first time in Algeria by Ould-Ahmed & Meinesz (2007), and later by Ould-Ahmed (2015) in Bou-Ismail, Sidi-Fredj and Ain Benian. Three new species belong to the order Ulvales: Ulva prolifera, Ulvella lens and Blidingia minima and two to the order Cladophorales: Chaeotomorpha ligustica and Microdictyon umbilicatum. These five species are cited along all the Mediterranean coasts. Regarding the remaining new species, Bryopsis secunda, is only known from the Mediterranean Sea (Guiry & Guiry 2019). Cormaci & al. (2014) indicated that is a rare species and according Pignatti (1962) most of the ancient records are misidentifications for Bryopsis hypnoides.
Biogeographically, the Algerian flora of Ulvophyceae is characterized by a high number of sub-cosmopolitan and cosmopolitan taxa (28 taxa, 38%) followed by Atlantic taxa (11 taxa, 15%), Mediterranean and Indo-Atlantic (8 taxa each, 11%), Pantropical (7 taxa, 10%) and Atlanto-Pacific and Indo-Pacific (5 taxa each, 7%). The circumboreal taxa are scarcely represented (1 species). This biogeographical composition of the Algerian flora of Ulvophyceae is similar to the observed in Algerian flora of Phaeophyceae by Ould-Ahmed & al. (2013).
