Abstract

LOBATO, César  and  NOVELO, Eberto. Cyanoprokaryota and microalgae from two lakes of the Pantanos de Centla Biosphere Reserve, Tabasco, Mexico. Rev. Mex. Biodiv. [online]. 2023, vol.94, e945055.  Epub July 31, 2023. ISSN 2007-8706.  https://doi.org/10.22201/ib.20078706e.2023.94.5055.

In Tabasco, 699 freshwater algal taxa have been recognized, a number that we consider low, given that it protects the most significant number of water bodies in the country and, where the Pantanos de Centla Biosphere Reserve (RBPC) is located, the largest tropical wetland in the region, which due to its complex hydrology and biodiversity is one of the most important sites of Mesoamerica. The main objective of this study was to record and document phytoplankton species in El Viento and San Pedrito lagoons, located inside the RBPC, during 2 periods, northern rains (November 2016) and dry (February 2017). Sixty-seven species were documented, 4 of them recorded for Mexico for the first time, and 17 for the state: 67% occur in eutrophicated aquatic systems, with a typically planktonic life form (73%). The quantity and variety of aquatic bodies in the state, the location of the RBPC and the influence of the Grijalva-Usumacinta hydrological region, make remarkable the great diversity of algae and of photoautotrophic prokaryotes (Cyanoprokaryota).
