Abstract Background and Aims Kelps are the primary foundation species in temperate
subtidal rocky shores worldwide. However, global change is causing their decline with …

Effective monitoring of non-indigenous seaweeds and combatting their effects relies on a
solid confirmation of the non-indigenous status of the respective species. We critically …

Maerl beds are unique marine habitats hosting a great diversity of organisms while
macroalgae are a major component of this diversity. The bay of Brest is one of the most …

Species identification in red algae poses significant challenges when relying solely on
morphological characteristics. Consequently, the absence of molecular information often …

Algal turfs are ecosystem engineers receiving steadily growing attention in recent years in
relation to their expansion on temperate reefs due to global change. However, their species …

Cryptic diversity is common among marine macroalgae, with molecular tools leading to the
discovery of many new species. To assign names to these morphologically similar species …

Molecular analyses, in combination with morphological studies, provide invaluable tools for
delineating red algal taxa. However, molecular datasets are incomplete and taxonomic …

The use of molecular tools in red algal diversity surveys often reveals the existence of
undescribed species. Here, we report a new Macaronesian turf-forming red alga in the …

The decline of kelps and algal canopies and the expansion of algal turfs because of global
change is a recurrent pattern reported in temperate coasts worldwide. This pattern has also …
