| description | Background and Aims: In Mexico, knowledge of epiphytism in marine environments has focused on pasture communities, while for algae there are only four studies, two for the North Pacific of Mexico and two more for Veracruz. Due to the lack of information, the present work intends to contribute to the knowledge of the epiphytism presented in two species of Padina of wide distribution along the coasts of the Mexican tropical Pacific.
Methods: Two sampling periods were carried out in four locations in Nayarit. The collected material was preserved in 4% formaldehyde. Thallus determinations of Padina crispata and P. durvillei were made, observations of the epiphyte thallus were carried out and cuts were observed with stereoscopic and optical microscopes. The identification was carried out with specialized literature. In addition, a bibliographic review was made with works about the coasts of the Mexican tropical Pacific.
Key results: In total 71 epiphytic species of Padina crispata and P. durvillei were identified, distributed in 51 genera, 35 families, 22 orders and four phyla. The order with the highest number of recorded species was Ceramiales with 17, followed by Corallinales with 14, while the best represented families were Corallinaceae and Ceramiaceae with 11 and nine species, respectively. Eight species were found for the first time in Nayarit, of which Acrochaetium barbadense is a new record for the Mexican tropical Pacific. The greatest richness of epiphytic species occurred in Padina durvillei (58, 80.5 %).
Conclusions: The importance of Padina durvillei and P. crispata as basibionts for different groups of algae is highlighted, as well as the value they present in the knowledge of biodiversity. |

Antecedentes y Objetivos: En México el conocimiento de epifitismo en ambientes marinos se ha enfocado en las comunidades de pastos, mientras que para las algas únicamente se cuenta con cuatro estudios, dos para el Pacífico norte de México y dos para Veracruz. Debido a la escasez de información, el presente trabajo es una contribución importante al conocimiento del epifitismo en dos especies de Padina de amplia distribución en las costas del Pacífico tropical mexicano. Métodos: Se llevaron a cabo dos periodos de muestreo en cuatro localidades de Nayarit. El material recolectado fue preservado en formaldehído a 4%. Se realizaron las determinaciones de Padina durvillei y P. crispata, a partir de observaciones de los talos epífitos, realizando y analizando cortes al microscopio estereoscópico y óptico. La identificación se realizó utilizando literatura especializada. Para corroborar la determinación y conocer la distribución de las especies, se llevó a cabo la revisión bibliográfica de trabajos ficológicos sobre las costas del Pacifico tropical mexicano. Resultados clave: En total se identificaron 71 especies epífitas de Padina crispata y P. durvillei, distribuidos en 51 géneros, 35 familias, 22 órdenes y cuatro phyla. El orden con mayor número de especies registradas fue Ceramiales con 17, seguido de Corallinales con 14, mientras que las familias mejor representadas fueron Corallinaceae y Ceramiaceae con 11 y nueve especies respectivamente. Se encontraron por primera vez ocho especies para Nayarit, de las cuales Acrochaetium barbadense es un nuevo registro para el Pacifico tropical mexicano. La mayor riqueza de especies epífitas (58, 80.5%) se presentó en Padina durvillei. Conclusiones: Se destaca la importancia de Padina durvillei y P. crispata como basibiontes para diferentes grupos de algas, así como el valor que éstas presentan en el conocimiento de la biodiversidad.
