Overview

Randomized trial assesses distribution of Avrainvillea canariensis in marine ecosystems, highlighting conservation needs.

Key Points

  • This research aims to document the distribution of the endemic macroalga Avrainvillea canariensis in the Canary Islands and identify new habitats.
  • Conducted research off El Hierro using Baited Remote Underwater Video Systems to locate algal meadows.
  • Measured densities of A. canariensis populations at depths of 40–45 m.
  • Identified dense meadows of A. canariensis with a maximum density of 100 individuals/m².
  • Extended the known distribution of the species, establishing a new southernmost limit in Macaronesia.
  • Documented the ecological roles of these meadows, supporting various marine fauna.
