Lista actualizada y nuevos registros de las algas rojas (Rhodophyta) del litoral de Michoacán, México

Marine epiphyte studies in Mexico, including macroalgae, are lacking in the published literature. Floristic studies have been mainly focused on identifying the algae growing on rocky substrata, and epiphytic algae have been recorded, but only occasionally. The aim of this work is to establish the current state of knowledge of the epiphytic macroalgae and their hosts on the Mexican coasts. A systematic revision of the literature published from 1950 to 2021 is also reported, the literature information is included, and the composition, species richness, current state of knowledge of the epiphytic marine macroalgae, and their relationship with the various marine Mexican ecoregions are reported. Sixty-one publications since 1950 included at least one record of epiphytic macroalgae. In this study, 615 species of epiphytic macroalgae and 224 species of hosts for Mexico are reported. This checklist will provide a baseline for future taxonomic and biogeographic studies of the epiphytic marine algae in the country.

Background and Aims: Macroalgae are primary producers of marine ecosystems, so the information regarding their species composition and distribution is necessary to develop conservation strategies and sustainable use of the coastal coastlines they inhabit. However, in different marine regions of Colombia, such as the Gulf of Morrosquillo, this knowledge is scarce, requiring a greater sampling effort and constant updating of data. Therefore, this work aims to provide an updated list of the macroalgae in the aforementioned region, based on published and unpublished biological records and recent sampling. Methods: Bibliographic information was compiled from historical records from 1976 to the present and complemented with sampling in one location in the Gulf of Morrosquillo. The taxa were organized and updated based on the most recent nomenclature, and the geographical affinity of the algal flora was determined using the Cheney index.Key results: The occurrence of 97 taxa classified in three classes, 15 orders, 32 families and 54 genera. Red algae, with 48 taxa, were the group that contributed the largest number of species, and the phycoflora of the region was of a mixed type according to the Cheney index. Six new annotated and illustrated records were reported for the Gulf: Antithamnionella breviramosa, Centroceras gasparrinii, Bostrychia tenella, Melanothamnus sphaerocarpus, Agardhiella ramosissima and Feldmannia mitchelliae.Conclusions: The inventory of macroalgae in the evaluated region was updated, showing a clearer historical panorama of the sampled areas, which suggests an extraordinary potential in the future discovery of new records that would increase the knowledge about the phycoflora of the Colombian Caribbean, particularly because the records of encrusting red algae, epiphytic and epizoic species are non-existent.
