JEREZ-RAMIREZ, Nelly Alejandra et al. Composition and spatiotemporal diversity of the aquatic bird community in Laguna de las Ilusiones, Tabasco, Mexico. Cienc. mar [online]. 2023, vol.49, e3355.  Epub 08-Dic-2023. ISSN 0185-3880.  https://doi.org/10.7773/cm.y2023.3355.

In Laguna de las Ilusiones, Villahermosa, Tabasco, Mexico, bird species interact with the anthropic elements of the landscape. Waterfowl sightings were made with the fixed-point counting method during the dry and rainy seasons of the year 2020 at 12 sampling sites in the lagoon. Urban, water physicochemical, vegetation, and macrohabitat variables were recorded at these sites to assess their influence on waterfowl. A total of 1,134 individuals belonging to 8 orders, 12 families, and 25 species were recorded. The most sighted species were Ardea alba, Egretta thula, and Butorides virescens. Species diversity (Shannon index) was higher in the dry season (H = 2.40 bits) and lower in the rainy season (H = 1.89 bits). The canonical analysis showed that species richness decreased as the percentage of urbanization in the vicinity of the sampling sites increased.
