Abstract

Halophila stipulacea (Hydrocharitaceae) in Laguna de Yapascua, San Esteban National Park, Carabobo, Venezuela.

Abstract

The species Halophila stipulacea, considered invasive on the coasts of the Caribbean, was reported for the first time in Venezuela in 2014, in Vargas state. In this study, the distribution of this species in the country is extended to the coast of Carabobo state. Sampling was conducted in a seagrass bed in Laguna Yapascua (San Esteban National Park). The vegetation cover and biomass were estimated, following the CARICOMP protocol. The seagrass H. stipulacea was distributed to the deep and inner zone of the lagoon, with an average biomass of 40.62 ± 28.43 g/m2 and coverage between 40-100%. These results show the expansion of this species towards the western coast of Venezuela, being necessary to evaluate the consequences on other species of seagrass and their associated community.
