Abstract

The phycoflora of the coast of Piauí is one of the least studied in the entire Brazilian territory. One of the ways to classify macroalgae is the use of morphofunctional groups, this approach is based on morphological, anatomical, physiological and ecological characteristics. Thus, this study aimed to characterize the structure of the benthic marine macroalgae community on Itaqui-PI beach, using the morphofunctional groups approach. The material was collected on Itaqui beach, in Piauí, in October 2022, following the methods of Cavalcanti & Fujii (2021) and identification according to Guiry & Guiry (2023). The categorization into morphofunctional groups was based on Steneck & Dethier (1994) and adaptations by Littler & Littler (2000) and Barbosa, Figueiredo and Testa (2008). The specimens were herborized (exsiccates) and deposited in the laboratory of the Federal Institute of Piauí. 50 taxa were identified, with a predominance of red macroalgae from the phylum Rhodophyta. The corticate morphotypes were the most abundant, suggesting a stable environment with low disturbance. Opportunistic morphotypes, such as leafy and filamentous, were present in smaller quantities and may indicate possible disturbances in the environment.
