Abstract
Las especies del complejo Laurencia son elementos importantes
en la estructura y diversidad de los ecosistemas costeros. Por primera vez, se analiza la distribución geográfica del complejo dentro
de la plataforma cubana, sus áreas marinas protegidas y se identifican áreas potenciales endémicas, considerando las ecozonas
en que se dividió la plataforma. A la fecha, se han inventariado 19
especies, de estas 10 pertenecen a Laurencia, una a Osmundea,
cinco a Palisada, dos a Yuzurua, y se incorporó Laurenciella como
nuevo género para Cuba. La distribución fue desigual, con un alto
número de especies y puntos de ocurrencia, especialmente en las
regiones Occidental y Central de la costa norte. El análisis de parsimonia de endemicidad indicó dos ecozonas, una en HabanaMatanzas y otra en la Costa Nordeste, sustentadas por tres y dos
especies endémicas, respectivamente.
Species of the Laurencia complex are important elements in the structure and diversity of coastal ecosystems. For the first time, we analyzed the geographical distribution of the complex within the Cuban shelf, its marine protected areas and identified potential endemic areas, considering the ecozones into which the shelf was divided. To date, 19 species have been inventoried, of which 10 belong to Laurencia, one to Osmundea, five to Palisada, two to Yuzurua, and Laurenciella a new record of genus for Cuba. The distribution was uneven, with a high number of species and occurrence points, especially in the Western and Central regions of the northern coast. The parsimony analysis of endemicity indicated two ecozones, one in Habana-Matanzas and the other in the Northeast Coast, supported by three and two endemic species, respectively.
