Abstract

We present an annotated checklist of the benthic marine and brackish algae of the Galician coasts (Spain) based on literature records and new collections. This checklist includes 618 species: 118 Cyanophyta, 296 Rhodophyta, 127 Ochrophyta, and 77 Chlorophyta. The number of specific, infraspecific taxa, and stages is 643: 121 Cyanophyta, 309 Rhodophyta, 135 Ochrophyta, and 79 Chlorophyta. Hyella caespitosa var. nitida, Calothrix fasciculata, Gracilariopsis longissima, Compsonema minutum, and Sphacelaria tribuloides are new records for Galicia, and there are also some new provincial records. We state the presence of each species for Lugo (Lu), A Coruña (Co), and Pontevedra (Po) provinces. The number of species found in Galicia is high, since 85% of the species recorded for the warm-temperate NE Atlantic Ocean grow in Galicia. Biogeographical comments comparing the Galician data with the neighboring areas of Britain and Ireland, Basque coast, Portugal, southern Iberian Peninsula, Canary Islands and Atlantic coast of Morocco are given. Finally, we present lists of cold-temperate, warm-temperate, Lusitanic Province endemics, and alien species growing in Galicia.

The retreat of large brown seaweeds on the north coast of Spain: the case ofSaccorhiza polyschides

“…The same trend has occurred in the two remaining kelp species, Laminaria hyperborea (Fig. 2), which is a subtidal species that was very common in the west part of the north coast of Spain in the 1970s and 1980s (McNeill, 1992) but also present east of Pen˜as Cape in the 1990s (my observations), and finally Saccharina latissima, which is a rare kelp on the north coast of Spain (Miranda, 1931;Anado´n & Niell, 1980;Weber-Peukert & Schnetter, 1982;Ba´rbara et al, 2005).…”

Climate driven changes in subtidal kelp forest communities in NW Spain

“…Species with a southern, warm temperate, distribution were present further south, sometimes until Cape Verde (West Africa). Where no information was given in Lünning (1990), the distribution as determined by Gorostiaga et al (2004), Barbara et al (2005) and Araujo et al (2009) was adopted. Taxa were indicated as cosmopolitan whenever no clear restriction in distribution was found.…”

Catálogo florístico de las cyanoprokariotas bentónicas del litoral de Andalucía. Checklist of the benthic cyanoprokariotas in Andalusian coast

“…Sobre cada taxón se ofrecen datos de su hábitat y distribución. Para la delimitación taxonómica se ha utilizado como bibliografía de base la obras de Bornet & Flahault (1886), Gomont (1892), Geitler (1932, Frémy (1934), Desikachari (1959), Umezaki (1961) y Komarek & Anagnostidis (1998, 2005.…”

“…En relación a las cyanoprokariotas marinas, a excepción de los trabajos de Miranda (1931) y González Guerrero (1945, 1947, las referencias a este grupo de organismos suelen aparecer de forma anecdótica en trabajos o listados generales y restringidas normalmente a las especies más comunes y aparentes. Como excepción a esta tendencia hay que señalar los trabajos de Calvo et al, (1999), Bárbara et al, (2005), Calvo (2001), Calvo & Bárbara (2002, 2003, De la Rosa, J. (2012) y De la Rosa et al, (2013), los cuales abordan de forma más particular y precisa el estudio de este grupo de microalgas.…”
