Economic Use

Red algae are the most conspicuous component in algal drifts that periodically arrive on the coasts of the Yucatan Peninsula. Given the presence of agars and carrageenans in their cell wall and the synthesis of secondary metabolites that act as antitumors or antioxidants, most of these species are highly valued in the international market. However, in this region of Mexico they are not used but represent a problem of waste from beaches. Our aim was to determine the composition of marine red algae of economic use in the algal drifts of the Yucatan Peninsula, providing brief descriptions, photographs that facilitate their identification and possible explanations for their causes and routes of origin. 13 samplings were carried out at 14 sites, collecting fresh and complete thalli from which the species of economic importance were described. 24 species distributed in six orders and seven families were identified. The most abundant families for both the number of species and the amount of biomass were Gracilariaceae (10 species), Rhodomelaceae (6 species) and Solieriaceae (3 species). The localities with the greatest diversity and biomass were those belonging to Campeche: Sabancuy (11 species), Punta Xen (14 species), Tortuga Bay (13 species) and Playa Bonita (13 species). From the present study we contributed six new records endemic to Campeche, including the first record of the genus Codiophyllum for the Western Atlantic Ocean. Our data on diversity, biomass, periodicity and growth rates of red algal drifts allow us to suggest that the Campeche and Yucatan drifts are a sustainable source of raw material.

A taxonomic checklist of sublittoral tanaidaceans from the north coast of the Yucatan Peninsula, southern Gulf of Mexico, is presented in this study; it includes notes on geographic distribution, habitat, and an identification key. The genus Cacoheterotanais and the species Cacoheterotanais rogerbamberi, Mesokalliapseudes macsweenyi, Pagurotanais largoensis, Parakonarus juliae, and Psammokalliapseudes granulosus have their known distribution range within the Gulf of Mexico expanded, and are considered new records; this increases the number of tanaidacean species to 23 for the southeastern Gulf, and to 87 for the entire Gulf of Mexico.

Background. The Gracilariaceae is one of the most diverse and abundant families of marine red algae. Most species in this family exhibit high morphological variability and overlapping of characters. In the Yucatan Peninsula 30 species have been historically recorded, but the phylogenetic identity for many of them is still unknown. Questions: Is the current diversity of the family in the area overestimated? Studied species: Crassiphycus caudatus, C. corneus, C. usneoides, Gracilaria flabelliformis, G. hayi, G. cf isabellana, G. microcarpa, G. occidentalis, G. suzanneae, Gracilariopsis tenuifrons. Study site and dates: Campeche: km 33 carretera Champotón, Bahía Tortuga, Puente Xen Kan III, Punta Xen, Sabancuy, 2017, 2018; Yucatan: Puerto Sisal, Puerto Progreso, Puerto Chicxulub, Puerto Telchac, 2018; Quintana Roo: Playa 88, Xcalacoco, Punta Esmeralda, 2019. Methods. Phylogenetic analysis (with COI-5P and rbcL sequences), supported by DNA species delimitation methods, genetic distances and morphological comparisons, allowed us to molecularly identify the specimens collected. Results. The phylogenetic identity of 10 species of Gracilariaceae was confirmed, two of which are new records for the Mexican Atlantic: G. hayi and G. suzanneae. Conclusion. The study demonstrated that the molecular assessment has proved to be very useful for the diversity evaluation, thus, the future phylogenetic identifies for the rest of morphospecies recorded in the area will allow a better approximation of Gracilariaceae diversity species.
