CUEVAS SANCHEZ, Estefany; DRECKMANN, Kurt M.; NUNEZ RESENDIZ, María Luisa  e  SENTIES, Abel. Updated systematic list of the estuarine macroalgae from Veracruz, Mexico. Act. Bot. Mex [online]. 2022, n.129, e2105.  Epub 06-Fev-2023. ISSN 2448-7589.

Background and Aims:

The Veracruz estuarine systems cover 1166 km2, corresponding to 14 coastal lagoons, that constitute one of the aquatic environments with the greatest diversity and productivity. They are critical environments for economically important species, such as macroalgae, which depend on them for their reproduction, feeding, establishment and refuge. Although the above makes them ideal candidates for conservation biology studies, there are only two contributions prior to 1995 on estuarine phycology. Therefore, the objective of this work was to elaborate an updated systematic list of the estuarine macroalgae of Veracruz, together with a graphical analysis, which contributes to the knowledge of the group and serves as a reference for subsequent biogeographical, ecological or conservation research.


Phycological literature published from 1963 to September 2022, as well as the UAMIZ herbarium database, were reviewed to complement and update the records. For the taxonomic determination of the specimens, an external morphological study was carried out. The synonymy and nomenclatural status were reviewed in AlgaeBase. From the records obtained, a graphic analysis was performed .

Key results:

An updated list with 113 species of estuarine macroalgae is presented: 62 Rhodophyta, 26 Phaeophyceae, Ochrophyta and 25 Chlorophyta, distributed in 24 orders, 38 families and 68 genera.


According to what was observed, there are few or no phycological studies in Veracruz estuarine environments, which causes a gap in the context of the diverse estuarine macroalgae. This list, in addition to being an updated contribution for Veracruz, is a starting point to undertake future analyses that help establish areas of biological importance in these environments, in order to maximize diversity. In addition, the need for constant phycofloristic monitoring in estuaries is evident.
