Rhodolith beds in the eastern tropical pacific: habitat structure and associate...
Diaz-Licona, Celeste A.; Schubert, Nadine; González-Gamboa, Vladimir; Tuya, Fernando; Azofeifa-Solano, Juan Carlos; Fernández-García, CindyRhodolith beds (RBs) are globally distributed marine benthic habitats and recognized biodiversity hotspots of conservation interest. However, considerable regions of the world's oceans remain unknown in terms of the presence, distribution, structure, and associated biodiversity of such habitats. In the Eastern Tropical Pacific (ETP), even basic information about these habitats is still extremely scarce. To fill...
Withstanding the heat: resilience of free-living coralline algae to marine heat...
Nannini, Matteo; Cerpelloni, Martina; Gaspar, Tainá L.; Peña, Viviana; Tuya, Fernando; Peñas, Julio; Rio, Jesús del; Vieira Mourato, CarolinaMarine heatwaves (MHWs) can severely impact benthic ecosystems, driving major ecological shifts. As they become longer, more frequent, and intense, MHWs are emerging as a dominant threat to marine biodiversity. Yet, their potential effects on coralline algal beds (CABs, including rhodolith beds), habitats of critical ecological importance, remain largely unknown. This study investigated the physiological respon...
Positive species interactions structure rhodolith bed communities at a global s...
Bulleri, Fabio; Schubert, Nadine; Hall‐Spencer, Jason M.; Basso, Daniela; Burdett, Heidi L.; Francini‐Filho, Ronaldo B.; Grall, Jacques; Horta, Paulo A.Rhodolith beds are diverse and globally distributed habitats. Nonetheless, the role of rhodoliths in structuring the associated species community through a hierarchy of positive interactions is yet to be recognised. In this review, we provide evidence that rhodoliths can function as foundation species of multi-level facilitation cascades and, hence, are fundamental for the persistence of hierarchically structur...
Effect of Depth across a Latitudinal Gradient in the Structure of Rhodolith Sea...
Pérez-Peris, Inés; Navarro-Mayoral, Sandra; de Esteban, Marcial Cosme; Tuya, Fernando; Peña, Viviana; Barbara, Ignacio; Neves, Pedro; Ribeiro, ClaudiaRhodolith seabeds are ‘ecosystem engineers’ composed of free-living calcareous red macroalgae, which create extensive marine habitats. This study addressed how depth influenced the structure (size and morphology) of rhodoliths and the abundance of associated floral and faunal epibionts across the Eastern Atlantic Ocean. Sampling was carried out at two sites within five regions (Brittany, Galicia, Madeira, Gran ...

Levelling-up rhodolith-bed science to address global-scale conservation challenges
Tuya, Fernando; Schubert, Nadine; Aguirre, Julio; Basso, Daniela; Bastos, Eduardo O.; Berchez, Flávio; Bernardino, Angelo F.; Bosch, Néstor E.Global marine conservation remains fractured by an imbalance in research efforts and policy actions, limiting progression towards sustainability. Rhodolith beds represent a prime example, as they have ecological importance on a global scale, provide a wealth of ecosystem functions and services, including biodiversity provision and potential climate change mit-igation, but remain disproportionately understudied,...
Drivers of variation in seagrass-associated amphipods across biogeographical areas
Navarro-Mayoral, Sandra; Tuya, Fernando; Prado, Patricia; Marco-Méndez, Candela; Fernandez-Gonzalez, Victoria; Fernández-Torquemada, YolandaAmphipods are one of the dominant epifaunal groups in seagrass meadows. However, our understanding of the biogeographical patterns in the distribution of these small crustaceans is limited. In this study, we investigated such patterns and the potential drivers in twelve Cymodocea nodosa meadows within four distinctive biogeo-graphical areas across 2000 Km and 13 degrees of latitude in two ocean basins (Mediterr...
DNA barcoding reveals cryptic diversity, taxonomic conflicts and novel biogeogr...
Neiva, J.; Bermejo, Ricardo; Medrano, Alba; Capdevila, Pol; Milla-Figueras, David; Afonso, Pedro; Ballesteros, Enric; Sabour, Brahim; Serio, DonatellaCystoseira sensu lato (s.l.) - encompassing the genera Cystoseira sensu stricto (s.s.), Ericaria and Gongolaria - is a diverse group of forest-forming brown macroalgae endemic to the warm-temperate North-east Atlantic. These algae have immense biogeographic and ecological significance and have been experiencing recent regional declines. Most Cystoseira s.l. display important morphological plasticity and can be ...
Rhodolith physiology across the atlantic: towards a better mechanistic understa...
Schubert, Nadine; Peña, Viviana; Salazar, Vinícius W.; Horta, Paulo A.; Neves, Pedro; Ribeiro, Cláudia; Otero-Ferrer, Francisco; Tuya, FernandoCoralline algae are important components in a large variety of ecosystems. Among them, rhodoliths are a group of free-living coralline red algae that cover extensive coastal areas, from tropical to polar regions. In contrast to other ecosystem engineers, limited research efforts preclude our understanding of their physiology, underlying mechanisms, drivers and potential differences related to species under vary...
Leveraging the blue economy to transform marine forest restoration
Filbee-Dexter, Karen; Wernberg, Thomas; Barreiro, Rodolfo; Coleman, Melinda A.; Bettignies, Thibaut de; Feehan, Colette J.; Franco, Joao N.The UN Decade of Ecosystem Restoration is a response to the urgent need to substantially accelerate and upscale ecological restoration to secure Earth’s sustainable future. Globally, restoration commitments have focused overwhelmingly on terrestrial forests. In contrast, despite a strong value proposition, efforts to restore seaweed forests lag far behind other major ecosystems and continue to be dominated by s...
