Bimodal spore release heights in the water column enhance local retention and population connectivity of bull kelp, .

Dispersal of reproductive propagules determines recruitment patterns and connectivity among populations and can influence how populations respond to major disturbance events. Dispersal distributions can depend on propagule release strategies. For instance, the bull kelp, , can release propagules (spores) from two heights in the water column ("bimodal release"): at the water surface, directly from the reproductive tissues (sori) on the kelp's blades, and near the seafloor after the sori abscise and sink through the water column.

Role of macroalgal forests within Mediterranean shallow bays in blue carbon storage.

Although seaweeds rank among the most productive vegetated habitats globally, their inclusion within Blue Carbon frameworks is at its onset, partially because they usually grow in rocky substrates and their organic carbon (C) is mostly exported and stored beyond their habitat and thus, demonstrating its long-term storage is challenging. Here, we studied the sedimentary C storage in macroalgal forests dominated by Gongolaria barbata and in adjacent seagrass Cymodocea nodosa mixed with Caulerpa prolifera algae meadows, and bare sand habitats in Mediterranean shallow coastal embayments. We characterized the biogeochemistry of top 30 cm sedimentary deposits, including sediment grain-size, organic matter and C contents, C burial rates and the provenance of sedimentary C throughout stable carbon isotopes (δC) and pyrolysis analyses.

[Cost-effectiveness analysis of fracture liaison services in Catalonia].

Objective: To assess the cost-effectiveness of Fracture Liaison Service (FLS) compared to the standard of care for secondary prevention of fragility fractures form the perspective of the Catalan Health Service.

Methods: Cost-utility assessment through a Markov model that simulated disease progression of a patients' cohort candidates to initiate antiosteoporotic treatment after a fragility fracture. A time horizon of 10 years and a 6-month duration per cycle was established.

Multiple scale assessment of habitat, landscape, and geographic-specific attributes driving decapod assemblages in Posidonia oceanica seagrass meadows.

Seagrass meadows are biodiversity hotspots for invertebrate species including decapods. Understanding the drivers of species abundance, richness and diversity of decapod assemblages is crucial for the conservation of such hotspots, but how drivers act across multiple spatial scales remains unexplored. Here we describe the decapod assemblages of Posidonia oceanica seagrass meadows and assess the influence of attributes from three increasing spatial scales (habitat, landscape, and geographical levels) on the assemblages' structure and composition, as well as the variability partitioning among each one of these levels.
