Abstract
espanolEl macrofitobentos marino cumple un papel importante en los arrecifes coralinos, sin embargo, son de los grupos biologicos menos estudiados en el Sistema Arrecifal Lobos-Tuxpan, Veracruz, Mexico (SALT). El objetivo del presente estudio fue actualizar la lista taxonomica de las especies de algas y fanerogamas presentes en los arrecifes Tuxpan, Enmedio, Tanhuijo, Lobos y Oro Verde. Entre el periodo 2014-2018, se realizaron un total de 38 muestreos, las exploraciones fueron en la laguna arrecifal y en las pendientes profundas de los arrecifes mediante buceos errantes. La busqueda de algas y fanerogamas marinas se realizo en cinco tipos de sustratos: arena, guijarros, rocas coralinas, pastos marinos y zona de corales vivos. Asi mismo, el listado taxonomico se complemento con registros de especies reportadas previamente para el SALT. La lista taxonomica actualizada esta compuesta por 130 especies: 2 pertenecen a Cyanobacteria, 55 Rhodophyta, 23 Ochrophyta, 48 Chlorophyta y 2 Tracheophyta representadas por Halophila decipiens y Thalassia testudinum. Del total de especies, 28 taxa se citan por primera vez para la zona de estudio. Ademas, Sphorochnus pedunculatus constituye un nuevo registro para el suroeste del golfo de Mexico. Los sustratos con mayor riqueza de algas fueron rocas coralinas y guijarros. Los arrecifes emergentes Lobos, Enmedio y Tuxpan presentaron mayor riqueza floristica. La presente informacion representa un buen avance en el conocimiento de la flora marina y puede ser de utilidad para la toma de decisiones eficaces en materia de manejo, en especial para las fanerogamas que presentan un estatus de riesgo.
