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 …

Our knowledge of seaweed diversity and biogeography still largely relies on information
derived from morphological identifications, but the use of molecular tools is revealing that …

Seaweed communities are important coastal ecosystems representing good indicators of
environmental variation related to climate change and other long-term changes. Long-term …

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 …

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

Introduced seaweeds and undescribed species often remain undetected because marine
regional floras are as yet poorly understood. DNA sequencing facilitates their detection, but …

The brown alga Rugulopteryx okamurae is one of the most recent and aggressive marine
invaders known, with a non-native range that spans from the western Mediterranean to the …

The Mar Piccolo of Taranto (southern Italy, Mediterranean Sea), a site of the European LTER
network, is a transitional water system, where a century-old intensive mussel farming activity …
