Macroalgae and seagrass meadows are widely recognized as foundational habitat-forming species that play a critical role in structuring and sustaining marine ecosystems. Under increasingly adverse environmental conditions, these macrophytes are likely to function as refugia for a wide range of marine organisms. However, the effectiveness of this role is strongly modulated by both abiotic factors and biotic interactions. Through their metabolic activity and morphology, these primary producers can actively regulate local environmental parameters and alleviate the negative impacts of environmental stressors, thereby enhancing the resilience and persistence of associated marine communities under extreme or fluctuating conditions.
Le macroalghe e le praterie di fanerogame marine sono ampiamente riconosciute come specie fondatrici capaci di strutturare e sostenere gli ecosistemi marini. In condizioni ambientali sempre più avverse, queste macrofite possono svolgere un ruolo cruciale come rifugi ecologici per una vasta gamma di organismi marini; tuttavia, l’efficacia di tale funzione è fortemente influenzata sia da fattori abiotici che da interazioni biotiche. Attraverso i loro processi metabolici e le caratteristiche morfologiche, questi produttori primari sono in grado di regolare i parametri ambientali locali e di attenuare gli impatti negativi degli stress ambientali, contribuendo così a rafforzare la resilienza e la persistenza delle comunità marine associate anche in condizioni estreme o fortemente variabili.

Abstract
Macroalgae and seagrass meadows are widely recognized as foundational habitat-forming species that play a critical role in structuring and sustaining marine ecosystems. Under increasingly adverse environmental conditions, these macrophytes are likely to function as refugia for a wide range of marine organisms. However, the effectiveness of this role is strongly modulated by both abiotic factors and biotic interactions. Through their metabolic activity and morphology, these primary producers can actively regulate local environmental parameters and alleviate the negative impacts of environmental stressors, thereby enhancing the resilience and persistence of associated marine communities under extreme or fluctuating conditions.| File | Dimensione | Formato | |
