- A common terminology to unify research and conservation of coralline algae and the habitats they createPublication . Jardim, Victor L.; Grall, Jacques; Barros‐Barreto, M. Beatriz; Bizien, Anaëlle; Benoit, Thomas; Braga, Juan C.; Brodie, Juliet; Burel, Thomas; Cabrito, Andrea; Diaz‐Pulido, Guillermo; Gagnon, Patrick; Hall‐Spencer, Jason M.; Helias, Mathieu; Horta, Paulo Antunes; Joshi, Siddhi; Kamenos, Nick A.; Kolzenburg, Regina; Krieger, Erik C.; Legrand, Erwann; Page, Tessa M.; Peña, Viviana; Ragazzola, Federica; Rasmusson, Lina M.; Rendina, Francesco; Schubert, Nadine; Silva, João; Tâmega, Frederico T. S.; Tauran, Adeline; Burdett, Heidi L.Linguistic uncertainty is a prime source of uncertainty pervading ecology and conservation. Coralline algae are a widespread and diverse group of calcifying red macroalgae that underpin coastal ecosystem function and service provision. Recent increasing interest in coralline algae in the scientific literature has revealed a diverse but confusing terminology at organism to habitat scales. Coralline algal research and conservation are international and multidisciplinary, so there are geographic and disciplinary imbalances in research and conservation efforts. To reach consensus and reduce uncertainty, we propose a unified terminology. We review trends in cultural and scientific use of coralline algal terms and propose a system based on six morphologies: (1) attached, (2) free-living geniculate, (3) encrusting and free-living nongeniculate coralline algae, the latter either being (4) nucleated or (5) non-nucleated thalli or (6) fragments. We take inspiration from other coastal systems that have achieved consensus through umbrella terms, such as 'coral' and 'kelp', to accelerate global progress in coralline algal research and conservation. We characterise 14 coralline algae-dominated habitat global types, falling within seven functional groups, four biomes and four realms: (1) freshwater coralline streams; (2) coralline tide pools; (3) intertidal coralline rims and (4) turf; (5) coralline sea caves; (6) coral-algal reefs; (7) algal ridges; (8) coralligenous reefs; subtidal (9) carbonate crusts, (10) coralline barrens and (11) turf; and (12) articulith, (13) maerl and (14) rhodolith beds, which fall into the coralline algal bed functional group. We hope this unified terminology promotes data comparison, enables cross-boundary and cross-sector sharing of best practices, develops capacity for meta-analyses and improves conservation strategies.
- The lush Fucales underwater forests off the Cilento Coast: An overlooked mediterranean biodiversity hotspotPublication . Rendina, Francesco; Falace, Annalisa; Alongi, Giuseppina; Buia, Maria Cristina; Neiva, J.; Appolloni, Luca; Marletta, Giuliana; Russo, Giovanni FulvioFucales (Phaeophyceae) are ecosystem engineers and forest-forming macroalgae whose populations are declining dramatically. In the Mediterranean Sea, Cystoseira sensu lato (s.l.)—encompassing the genera Cystoseira sensu stricto, Ericaria, and Gongolaria—is the most diverse group, and many species have been shown to be locally extinct in many areas, resulting in a shift toward structurally less complex habitats with the consequent loss of ecosystem functions and services. In this study, we report on the extensive occurrence of healthy and dense marine forests formed by Fucales in the Santa Maria di Castellabate Marine Protected Area in Cilento, Italy (Tyrrhenian Sea, Mediterranean). On a total area of 129.45 ha, 10 Cystoseira s.l. taxa were detected using a combined morphological and molecular approach, with an average cover of more than 70%. One of these taxa has been sequenced for the first time. These findings underline the high ecological value of this area as a hotspot of benthic biodiversity and highlight the importance of marine protected area management and regional monitoring programs to ensure the conservation of these valuable yet fragile coastal ecosystems.
