Lithophyllum species in the Mediterranean Sea function as algal bioconstructors, contributing to the formation of biogenic habitats such as coralligenous concretions. In such habitats, thalli of Lithophyllum, consisting of crusts or lamellae with entire or lobed margins, have been variously referred to as either one species, L. stictiforme, or two species, L. stictiforme and L. cabiochiae, in the recent literature. We investigated species diversity and phylogenetic relationships in these algae by sequencing three markers (psbA and rbcL genes, cox2,3 spacer), in conjunction with methods for algorithmic delimitation of species (ABGD and GMYC). Mediterranean subtidal Lithophyllum belong to a well‐supported lineage, hereby called the L. stictiforme complex, which also includes two species described from the Atlantic, L. lobatum and L. searlesii. Our results indicate that the L. stictiforme complex consists of at least 13 species. Among the Mediterranean species, some are widely distributed and span most of the western and central Mediterranean, whereas others appear to be restricted to specific localities. These patterns are interpreted as possibly resulting from allopatric speciation events that took place during the Messinian Salinity Crisis and subsequent glacial periods. A partial rbcL sequence from the lectotype of L. stictiforme unambiguously indicates that this name applies to the most common subtidal Lithophyllum in the central Mediterranean. We agree with recent treatments that considered L. cabiochiae and L. stictiforme conspecific. The diversity of Lithophyllum in Mediterranean coralligenous habitats has been substantially underestimated, and future work on these and other Mediterranean corallines should use identifications based on DNA sequences.

En comparación con la diversidad de macroalgas en el resto de los estados costeros del país, Tabasco aún presenta una baja riqueza de especies conocida (Pedroche y Sentíes, 2003), debido a que la mayoría de las aportaciones en el inventario de la ficoflora han sido de recolectas esporádicas y de revisiones de ejemplares de herbario (Quiroz-González et al, 2018).…”

“…El conocimiento que se tiene sobre macroalgas en el estado de Tabasco se ha incrementado en los últimos años, debido a las exploraciones y revisiones de los ejemplares ficológicos depositados en las colecciones de herbarios estatales y nacionales. A la fecha, se cuenta con el registro de 123 especies de Rhodophyta, 57 de Chlorophyta y 27 de Ochrophyta (Orozco-Vega y Dreckmann, 1995;Ra-mírez, 1996;Dreckmann y De Lara-Isassi, 2000;Sentíes y Dreckmann, 2013;Mendoza-González et al, 2017;Quiroz-González et al, 2017, 2018.

“…Las exploraciones ficológicas para La laguna Mecoacán, ubicada en el municipio Paraíso, se destacan por el estudio de Orozco-Vega y Dreckmann (1995), reportando siete especies las cuales están clasificadas en seis de Rhodophyta y una Ochrophyta; el registro de Ramírez (1996) (Ramírez, 1996;Sentíes y Dreckmann, 2013;Mendoza-González et al, 2017y Quiroz-González et al, 2017, 2018 han registrado especies de macroalgas en las escolleras del puerto Andrés Sánchez Magallanes, en el municipio Cárdenas. Finalmente, Sentíes y Dreckmann (2013), en su listado actualizado de macroalgas, realizaron un análisis de afinidades ficoflorísticas para Tabasco, reportando 50 especies distribuidas en cinco sitios (Escolleras Sánchez Magallanes, Playa El Bellote, Laguna Mecoacán y Playa Cangrejo).…”

Resumen:Antecedentes y Objetivos: Debido a la escasez de conocimiento sobre macroalgas en lagunas costeras de Tabasco, en este trabajo se determina ladiversidad ficoflorística de macroalgas asociadas a la laguna El Carmen, municipio Cárdenas, y se contribuye al conocimiento biológico y ecológicoen el estado de Tabasco.Métodos: Se realizaron muestreos en un ciclo anual de 2015 a 2016 durante la época de lluvias, la de nortes y la de secas. Los organismos se recolectaronmanualmente, se fijaron con agua marina y formol al 4%, se identificaron y se depositaron en los herbarios FCME (UNAM) y UJAT.Resultados clave: Se reportan 21 especies de macroalgas marinas, tres de las cuales son nuevos registros para el estado de Tabasco. La divisiónRhodophyta con las familias Gracilariaceae y Rhodomelaceae tiene la mayor riqueza de especies; Gracilaria blodgetti fue la más abundante. Durantela temporada de nortes se registró la mayor riqueza y abundancia.Conclusiones: Se incrementó a 125 el número de registros de Rhodophyta y 28 de Ochrophyta para Tabasco. Se sugiere ampliar el número de muestreossistemáticos en un ciclo anual con la finalidad de tener una mejor representación de la diversidad y la estacionalidad de las macroalgas en lalaguna El Carmen.Palabras clave: algas marinas, diversidad, estacionalidad, laguna costera.Abstract:Background and Aims: Due to the lack of knowledge about macroalgae in Tabasco’s coastal lagoons, this work determined the macroalgae diversityassociated to the El Carmen lagoon, municipality Cardenas, and contributes to the biological and ecological knowledge of the state of Tabasco, Mexico.Methods: Three samplings were carried out in an annual cycle from 2015 to 2016, during the rainy, northern wind and dry seasons. The organismswere collected manually, fixated with seawater and 4% formalin, identified, and deposited in the UJAT and FCME (UNAM) herbaria.Key results: Twenty-one species of marine macroalgae were recorded, of which three are new records for the state of Tabasco. The Rhodophyta divisionwith the families Gracilariaceae and Rhodomelaceae had the highest species richness and Gracilaria blodgetti was the most abundant species.The greatest diversity and abundance appeared in the northern winds season.Conclusions: There is an increase to 125 species in the number of records of Rhodophyta species and 28 in the Ochrophyta for Tabasco. Hence, it issuggested to extend the sampling time and perform systematic work in an annual cycle, in order to have a better representation of the diversity andseasonality of the macroalgae in the El Carmen lagoon.Key words: coastal lagoon, diversity, marine algae, seasonality.

The Biosphere Reserve of Sian Ka'an located in the Mexican Caribbean, where greatest diversity of seaweeds has been recorded. Despite of diversity and species richness there are limited phycological studies in the study area, suggesting that species diversity is not completely known. We reported species that complement previous reports of brown algae collected from the study area. In addition, brown algae recorded in the literature and the species present in the herbaria for the Biosphere Reserve of Sian Ka'an were also included, and data obtained from sampling at eleven localities during 2009 to 2012 were added. In all 50 infrageneric taxa are reported. Families Dictyotaceae and Sargassaceae comprised the most species richness. The presence of 11 species of Phaeophyceae is reported for the first time for the study area. Of them, Symphyocarpus strangulans is a new record for the Mexican Atlantic; eight species are new records for study area and two for Quintana Roo. The highest number of species was recorded for Punta Xoquem and Pulticub, while the lowest number of taxa was in Cayo Valencia. The highest number of species was found in summer rains, the lowest in winter rains. The obtained data highlights the high specific richness of Phaeophyceae indicating that the Sian Ka'an Reserve should be considered a priority area due to its great biodiversity. Moreover, these results will be a basis for future ecological, utilization and conservation studies.
