Abstract
NAVA-RUIZ, Viridiana Margarita and VALADEZ, Francisco. Planktonic flora from Lagartos Lagoon, Quintana Roo. Rev. Mex. Biodiv. [online]. 2012, vol.83, n.3, pp.561-582. ISSN 2007-8706. https://doi.org/10.7550/rmb.24868.
The planktonic flora from Lagartos Lagoon, Quintana Roo, was examined based on the observation of samples collected from November 2007 to September 2008. The superficial samples were collected with a Van Dorn bottle of 2 L, in the core part of the lagoon. A total of 67 taxa were identified: 28 Bacillariophyta, 22 Cyanoprokaryota, 7 Chlorophyta, 6 Dinoflagellata, 2 Euglenophyta and 2 Cryptophyta. Nevertheless, the blue green algae dominated during all study period, with more of 80% to the total abundance of the phytoplankton. The species Chroococcus pulcherrimus, Coelosphaerium confertum, Cyanodyction iac, Phormidium pachydermaticum, Planktolyngbya contorta, Rhodomonas minuta, Amphidinium massartii, Ensiculifera cf. loeblichii, Heterocapsa cf. pseudotriquetra, Prorocentrum cassubicum, Licmophora normaniana, Fistulifera saprophila and Amphora richardiana were recorded for the first time in Mexico. All the taxa are illustrated with microphotographs.
