- Collaborative bottom-up trust missions: a perspective on long-term strategies with and for people and naturePublication . Pelegrí, Josep L.; Bojanić, Natalia; Whyte, David; Pinto, Patrícia; Annasawmy, Pavanee; Burgues, Itziar; Bušelić, Ivana; Carbajal, Maria Elena; Fuster, Noemí; Giannoukakou-Leontsini, Ifigeneia; Hasler-Sheetal, Harald; Kaberi, Helen; Knigge, Thomas; Leitão, Francisco; Olivé, Irene; Palma, Jorge; Platzgummer, Emmanuelle; Quintana, Cintia O.; Simon, Carine; Tomaš, Ana VrdoljakThe 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 Missions, aimed at empowering citizens through networking and bottom-up transformative actions.
- A trait-based framework for seagrass ecology: trends and prospectsPublication . Moreira-Saporiti, Agustín; Teichberg, Mirta; Garnier, Eric; Cornelissen, J. Hans C.; Alcoverro, Teresa; Björk, Mats; Boström, Christoffer; Dattolo, Emanuela; Eklöf, Johan S.; Hasler-Sheetal, Harald; Marbà, Nuria; Marín-Guirao, Lázaro; Meysick, Lukas; Olivé, Irene; Reusch, Thorsten B. H.; Ruocco, Miriam; Silva, João; Sousa, Ana I.; Procaccini, Gabriele; Santos, RuiIn 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 angiosperms that colonized the ocean 100M YA and today make up productive yet threatened coastal ecosystems globally. Here, we compiled a comprehensive trait-based response-effect framework (TBF) which builds on previous concepts and ideas, including the use of traits for the study of community assembly processes, from dispersal and response to abiotic and biotic factors, to ecosystem function and service provision. We then apply this framework to the global seagrass literature, using a systematic review to identify the strengths, gaps, and opportunities of the field. Seagrass trait research has mostly focused on the effect of environmental drivers on traits, i.e., "environmental filtering" (72%), whereas links between traits and functions are less common (26.9%). Despite the richness of trait-based data available, concepts related to TBFs are rare in the seagrass literature (15% of studies), including the relative importance of neutral and niche assembly processes, or the influence of trait dominance or complementarity in ecosystem function provision. These knowledge gaps indicate ample potential for further research, highlighting the need to understand the links between the unique traits of seagrasses and the ecosystem services they provide.
