Collaborative bottom-up trust missions: a perspective on long-term strategies w...
Pelegrí, Josep L.; Bojanić, Natalia; Whyte, David; Pinto, Patrícia; Annasawmy, Pavanee; Burgues, Itziar; Bušelić, Ivana; Carbajal, Maria ElenaThe environmental and climate crises are linked to rising global inequity. Because of its centrality in the living Earth, the Ocean represents a unique opportunity to restore equity, engaging society through harmony with Nature. The United Nation's Ocean Decade and European Union's Mission Ocean and Waters recognize this centrality, but have focused on top-down actions. Here, we advocate for collaborative Trust...
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...
A trait-based framework for seagrass ecology: trends and prospects
Moreira-Saporiti, Agustín; Teichberg, Mirta; Garnier, Eric; Cornelissen, J. Hans C.; Alcoverro, Teresa; Björk, Mats; Boström, ChristofferIn the last three decades, quantitative approaches that rely on organism traits instead of taxonomy have advanced different fields of ecological research through establishing the mechanistic links between environmental drivers, functional traits, and ecosystem functions. A research subfield where trait-based approaches have been frequently used but poorly synthesized is the ecology of seagrasses; marine angiosp...
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,...
Contribution of the seagrass Syringodium isoetifolium to the metabolic function...
Olivé, Irene; García-Robledo, Emilio; Silva, João; Pintado-Herrera, Marina G.; Santos, Rui; Kamenos, Nicholas A.; Cuet, Pascale; Frouin, PatrickSeagrasses are gaining attention thanks to their metabolism and potential major role as carbon sinks, with further implications as nature-based solutions against climate change. Despite their recognized importance and the growing number of studies published, there is still a striking paucity of information on seagrass metabolism and contribution to biogeochemical cycles for some seagrass species and ocean areas...
Physiological potential of the chlorophyte Caulerpa prolifera for proliferation...
Olivé, Irene; E, Varela-Álvarez; Silva, João; Serrao, Ester; Santos, RuiOcean warming is altering the metabolic balances of organisms, favouring the expansion of thermo-tolerant individuals. The fast-growing macroalga Caulerpa prolifera is rapidly expanding in the Ria Formosa lagoon (Portugal), a connection area between Mediterranean and Atlantic basins. We investigated the metabolic capacity of C. prolifera to cope with ocean warming, to elucidate its expansion potential. The phot...
Seagrass meadows improve inflowing water quality in aquaculture ponds
de los Santos, Carmen B.; Olivé, Irene; Moreira, Márcio; Silva, André; Freitas, Cátia; Araújo Luna, Ravi; Quental-Ferreira, Hugo; Martins, MárcioWater quality is critical for fish health in aquaculture production. In flow-through systems, the inflowing water normally requires quality controls and treatments for being supplied from coastal water bodies that can be polluted by nutrients, suspended solids, and microorganisms. Here we assess how seagrass meadows benefit aquaculture systems through the provision of ecosystem services (water filtration, biolo...
Leaf proteome modulation and cytological features of seagrass Cymodocea nodosa ...
Piro, Amalia; Bernardo, Letizia; Serra, Ilia Anna; Barrote, Isabel; Olivé, Irene; Costa, Monya M.; Lucini, Luigi; Santos, Rui; Mazzuca, SilviaSeagrass Cymodocea nodosa was sampled off the Vulcano island, in the vicinity of a submarine volcanic vent. Leaf samples were collected from plants growing in a naturally acidified site, influenced by the long-term exposure to high CO2 emissions, and compared with others collected in a nearby meadow living at normal pCO2 conditions. The differential accumulated proteins in leaves growing in the two contrasting ...
Monitoring bubble production in a seagrass meadow using a source of opportunity
Felisberto, Paulo; Rodríguez, Orlando; Silva, João P.; Jesus, Sergio; Ferreira, Hugo Q.; Ferreira, Pedro P.; Cunha, Maria E.; de los Santos, Carmen B.Under high irradiance, the photosynthetic activity of dense seagrass meadows saturates the water forming oxygen bubbles. The diel cycle of bubble production peaks at mid-day, following light intensity pattern. It is well known that bubbles strongly affect the acoustic propagation, increasing signal attenuation and decreasing the effective water sound speed, noticeable at low frequencies. Thus, the diurnal varia...
