“…It is well known that further sampling in poorly explored areas of species with wide distributions can result in better-supported conclusions (Dijoux et al, 2014;Lee et al, 2013;Zuccarello et al, 2006). As Lobophora is reported in Tamaulipas and Campeche (as L. variegata;Dreckmann, 1998;García-García et al, 2021) the occurrence of other species, as well as some co-existing in the same localities, could have been overlooked.…”

“…The high number of recently discovered species of Lobophora around the world, the morphological similarities between species making the identification difficult, and the historical morphology-based records of Lobophora in several localities on the Atlantic coast of Mexico (as L. variegata ;Dreckmann, 1998;García-García et al, 2021;Ortega et al, 2001) prompted the need to re-evaluate the taxonomic identity of Lobophora species in Mexico using molecular data. In this study, DNA sequences of the mitochondrial cox3 and plastid psbA were compared from specimens collected from the states of Veracruz and Quintana Roo, Mexico, to investigate the species diversity and the occurrence of genetic differentiation in Lobophora.…”

Species of Lobophora (Dictyotales) are distributed throughout the sub-tropical and tropical seas worldwide. Recent analyses have revealed high species diversity in regions previously presumed to host only a single species, such as the Bismarck Sea, Eastern Pacific, Western Atlantic, Mediterranean Sea, and Greater Caribbean. Here, samples from Veracruz and Quintana Roo, Mexico, were collected, and 2 genetic markers (cox3 and psbA) were sequenced. The results confirmed the presence of L. dispersa and L. variegata. Lobophora dispersa is recorded for the first time on the Mexican coast. The distribution of its cox3 haplotypes shows genetic differentiation within the Greater Caribbean and Gulf of Mexico, possibly indicating limited dispersal and isolation by distance. Lobophora variegata exhibits lower genetic variability compared to L. dispersa, but its haplotypes did not show any obvious pattern. Lobophora declerckii, previously reported in the “Anegada de Afuera” reef, Veracruz, was not found, possibly due to its affinity to subtidal depths. Morphologically, L. dispersa and L. variegata align with previous descriptions, although we observed more variation in thallus cell thickness in L. dispersa. However, relying solely on morphological characters is insufficient to confidently identify the species, necessitating further sampling to determine the species diversity in Mexico.

“…Existen dos trabajos enfocados exclusivamente a las algas verdes (Chlorophyta) del litoral de Veracruz, el de Garduño-Solórzano et al (2005) quienes reportaron 72 especies, y el de García-López et al (2017) quienes citaron 82 Chlorophyta. Recientemente, García-García et al (2020), en una actualización taxonómica de las algas rojas bentónicas del Atlántico de México, incluyeron 153 taxones para el litoral veracruzano.…”

Antecedentes y Objetivos: Los primeros registros de algas marinas bentónicas para el litoral de Veracruz datan de 1846; después de 114 años, ficólogos mexicanos reiniciaron su estudio. Actualmente, se tienen registradas 312 especies. Considerando está riqueza específica, las modificaciones y actualizaciones taxonómicas en diversos grupos, el objetivo de este trabajo fue presentar una lista de las algas marinas del litoral veracruzano organizadas por categorías taxonómicas incluyendo datos de distribución, temporalidad y nuevos registros para el área de estudio. Métodos: Se realizaron 92 muestreos durante 18 años, en el nivel intermareal de 11 localidades del litoral, se obtuvieron registros previos desde 1960 a 2020 a través de una revisión bibliográfica y de la colección ficológica del herbario ENCB. El estatus nomenclatural de cada especie y el sistema de clasificación fueron revisados y actualizados. La diversidad α para cada localidad fue calculada con el índice de Shannon-Wiener; también se realizó un análisis de agrupamiento mediante UPGMA con el programa PAST v. 3. Resultados clave: El listado ficoflorístico incluye 316 taxones de algas marinas bentónicas distribuidas en 3 Phyla, 6 clases, 31 órdenes, 60 familias y 130 géneros. Cada especie incluye distribución en el litoral de Veracruz, reproducción, estacionalidad, hábitat, observaciones, bibliografía y número de catálogo del herbario ENCB. Los análisis de diversidad α muestran que la mayor diversidad está en las localidades con sustrato predominantemente rocoso con 180 especies. Las lluvias de verano registraron un elevado número de especies (269); Barra de Cazones alberga 181 especies, además, se encontraron 70 registros nuevos; así, el número de taxones aumentó a 391. Conclusiones: El listado revela una mayor riqueza específica de algas marinas comparada con la registrada en Yucatán, Campeche y Tabasco. La afinidad fitogeográfica de las algas del litoral de Veracruz es mixta, ya que ahí confluyen taxones tropicales y caribeños. Es necesario mantener un monitoreo constante para determinar cambios de la comunidad de algas para establecer programas de conservación y aprovechamiento.

“…Particularly, in the Gulf of Mexico and the Mexican Caribbean, which represents one of the sites with great environmental heterogeneity in the country (García-García et al 2021), conducive to the establishment of different biological groups, only 148 species have been recorded (León-Tejera et al 2016b). Even though in these environments where the cyanoprokaryotes, mainly Nostocales, constitute one of the most conspicuous groups due to their diversity and abundance, they have gone almost unnoticed.…”

Background: Nostocales is a widely distributed, monophyletic order of cyanobacteria, whose species are mainly characterized by the presence of specialized structures such as heterocytes and akinetes. Despite being the most diverse group in marine environments, little is known about coastal species in Mexico. Particularly in Veracruz, only 17 species have been recorded, without photographic, morphological references, or ecological data; these records are only mentioned in floristic lists. Questions and / or Hypotheses: The present study aimed to contribute to the knowledge of the diversity of benthic marine Nostocales species in Veracruz, Mexico, as well as to provide detailed descriptions and illustrations of the species found, which can serve as a reference in subsequent studies. Study site and dates: Collect of cyanobacterial growths were made in three locations throughout Veracruz in 2020. Methods: The organisms were isolated from the field material. With the use of specialized taxonomic keys, they were morphologically identified, described and photographed. Results: A total of 20 Nostocales species were obtained, of which 17 were additions to the phycoflora of Veracruz, constituting an increase of 55 %. Taxonomic notes are added highlighting their differences with the literature. One of the species was identified as cf. and seven as sp., because their characteristics fully coincided with the generic morphology, but did not completely concur with the literature. Conclusions: These suggest that several records could correspond to new taxon not yet described that must be confirmed with different molecular markers.
