Marine protected areas stage of establishment and level of protection are good ...
Horta e Costa, Barbara; Benito-Abelló, Carmela de; Pike, Elizabeth; Turnbull, John; MacCarthy, Jessica; Harasta, Nikki; Fragkopoulou, ElizaDespite the importance of active management and strong protection in driving marine protected areas (MPA) performance, coverage area remains the sole indicator for global targets. To assess whether conservation quality lags behind quantity, we conducted a global meta-analysis of 123 MPAs. We show that MPAs’ Levels of Protection and Stages of Establishment are reliable proxies for MPAs’ ecological outcomes; henc...
Trophic convergence of marine vertebrate communities worldwide
González-Trujillo, Juan David; Assis, Jorge; Serrao, Ester A.; Costello, Mark John; Fragkopoulou, Eliza; Mendoza, Manuel; Araújo, Miguel B.Biogeographic regions arise due to constraints on species ranges, fostering lineage divergence as a result. Yet, convergent evolution means that evolutionary distinct lineages can share similar characteristics when subjected to similar environmental conditions. The ecological convergence of distinct regions has been demonstrated in terrestrial communities, but it remains uncertain if marine systems exhibit simi...
Coastal oceanographic connectivity at the global scale: a dataset of pairwise p...
Assis, Jorge; Fragkopoulou, Eliza; Serrao, Ester A.; Bastos Araújo, MiguelOcean currents are fundamental drivers of marine biodiversity distribution, mediating the exchange of genetic material and individuals between populations. Their effect ranges from creating barriers that foster isolation to facilitating long-distance dispersal, which is crucial for species expansion and resilience in the face of climate change. Despite the significance of oceanographic connectivity, comprehensi...

Global intraspecific diversity of marine forests of brown macroalgae predicted ...
Fragkopoulou, Eliza; Serrao, Ester A.; Clerck, Olivier De; Assis, JorgeGlobal patterns of intraspecific genetic diversity are key to understanding evolutionary and ecological processes. However, insights into the distribution and drivers of genetic diversity remain limited, particularly for marine species. Here, we explain and predict the genetic diversity of cold and temperate brown macroalgae using genetic data from 29 species and a machine-learning algorithm that incorporates c...
Range map data of marine ecosystem structuring species under global climate change
Gouvêa, Lidiane; Fragkopoulou, Eliza; Legrand, Térence; Serrao, Ester; Assis, JorgeData on contemporary and future geographical distributions of marine species are crucial for guiding conservation and management policies in face of climate change. However, available distributional patterns have overlooked key ecosystem structuring species, despite their numerous ecological and socioeconomic services. Future range estimates are mostly available for few species at regional scales, and often rel...
Potential consequences of future climate change for ecosystem structuring species
Fragkopoulou, ElizaClimate change is rapidly shifting marine species distributions, with more changes anticipated for the future. For species that structure essential habitats, climate change effects can be magnified into losses of ecosystem services and functioning. Despite the key role of marine ecosystem structuring species, baseline information on their global status and projections of their biodiversity patterns are incomple...
Bio‐ORACLE v3.0. pushing marine data layers to the CMIP6 earth system models of...
Assis, Jorge; Fernández Bejarano, Salvador Jesús; Salazar, Vinícius W.; Schepers, Lennert; Gouvêa, Lidiane; Fragkopoulou, Eliza; Leclercq, FredericMotivation: Impacts of climate change on marine biodiversity are often projected with species distribution modelling using standardized data layers representing physical, chemical and biological conditions of the global ocean. Yet, the available data layers (1) have not been updated to incorporate data of the Sixth Phase of the Coupled Model Intercomparison Project (CMIP6), which comprise the Shared Socioeconom...
A global dataset of demosponge distribution records
Vafeiadou, Ariadni; Fragkopoulou, Eliza; Assis, JorgeBiodiversity information in the form of species occurrence records is key for monitoring and predicting current and fu- ture biodiversity patterns, as well as for guiding conserva- tion and management strategies. However, the reliability and accuracy of this information are frequently undermined by taxonomic and spatial errors. Additionally, biodiversity in- formation facilities often share data in diverse inco...
Kelp forest diversity under projected end‐of‐century climate change
Assis, Jorge; Fragkopoulou, Eliza; Gouvêa, Lidiane; Araújo, Miguel B.; Serrao, EsterAim: Future climate change threatens marine forests across the world, potentially disrupting ecosystem function and services. Nonetheless, the direction and intensity of climate-induced changes in kelp forest biodiversity remain unknown, precluding well-informed conservation and management practices. Location: Global. Methods: We use machine-learning models to forecast global changes in species richness and com...
