Resumen:
Background. The macroalgae of the tropical Mexican Pacific have been
studied and results published in numerous texts since the 1940s.
Nevertheless, there is no compilation of records of macroalgae from reef
communities, nor have specific inventories of reef macroalgae been
prepared. Objective. To integrate the knowledge generated on the
tropical Mexican Pacific coral reef macroalgae. Carry out an integration
of the knowledge generated on reef macroalgae and make inventories of
these macroalgae in the reefs of Gue-rrero and Oaxaca in the Mexican
tropical Pacific. Methods. Sorensen(sic)s similarity analysis and
Non-Metric Multidimensional Scaling (NDMS) analysis were applied to data
of algal composition from different coral reefs to determine their
distribution patterns. The ANOSIM analysis method was applied to
demonstrate the significant differences between groups. Results. The
total number of macroalgal species was 144, 100 Rhodophyta, 32
Chlorophyta and 12 Ochrophyta-Phaeopyceae; 75 were exclusive to
Guerrero, 24 to Oaxaca, and the number of shared species was 45. El
Zacatoso, Guerrero, had 92 species and was the locality with the
greatest specific richness. The Sorensen Index indicated a similarity of
more than 50% among most localities, but with a clear separation
between the communities of Guerrero and Oaxaca. Four groups were formed
by localities' species with the NMDS analysis without seasonal effect
(rainy and dry), ANOSIM shows significant differences among the
localities of each group. Conclusion. This work represents the first
inven-tory of the reef-inhabiting macroalgae of Guerrero and Oaxaca, the
only states in the Mexican tropical Pacific with specific systematic
reports on this type of coral reef algae. This study provides baseline
information to develop a regional monitoring program, a diagnosis of the
degree of disturbance of coral reefs and generate conservation
strategies and plans for these ecosystems.
