Where the grass is greenest in seagrass seascapes depends on life history and s...
Eggertsen, Linda; Goodell, Whitney; Cordeiro, Cesar A. M. M.; Cossa, Damboia; Lucena, Marcos de; Berkström, Charlotte; Franco, Joao N.Tropical seagrass meadows are critical habitats for many fish species, yet few studies have investigated the influence of multiple scale-dependent factors and marine protected areas on seagrass fish species of differing life histories. We assessed the influence of fine-scale seagrass meadow characteristics and seascape-scale variables on the abundance of fish in a seagrass-dominated seascape in the Bazaruto Arc...
Dynamics and fate of blue carbon in a mangrove–seagrass seascape: influence of ...
Dahl, Martin; Ismail, Rashid O.; Arias-Ortiz, Ariane; Deyanova, Diana; Franco, Joao N.; Hammar, Linus; Hoamby, Arielle I.; Linderholm, Hans W.Context: Seagrass meadows act as efficient natural carbon sinks by sequestering atmospheric CO2 and through trapping of allochthonous organic material, thereby preserving organic carbon (Corg) in their sediments. Less understood is the influence of landscape configuration and transformation (land-use change) on carbon sequestration dynamics in coastal seascapes across the land–sea interface. Objectives: We expl...
High seasonal variability in sediment carbon stocks of cold‐temperate seagrass ...
Dahl, Martin; Asplund, Maria E.; Deyanova, Diana; Franco, Joao N.; Koliji, Alan; Infantes, Eduardo; Perry, Diana; Björk, Mats; Gullström, MartinSeagrass meadows have a high ability to capture and store atmospheric CO2 in the plant biomass and underlying sediment and thereby function as efficient carbon sinks. The seagrass Zostera marina is a common species in the temperate Northern Hemisphere, a region with strong seasonal variations in climate. How seasonality affects carbon storage capacity in seagrass meadows is largely unknown, and therefore, in th...
Depth-specific fluctuations of gene expression and protein abundance modulate t...
Procaccini, Gabriele; Ruocco, Miriam; Marin-Guirao, Lazaro; Dattolo, Emanuela; Brunet, Christophe; D'Esposito, Daniela; Lauritano, ChiaraHere we present the results of a multiple organizational level analysis conceived to identify acclimative/adaptive strategies exhibited by the seagrass Posidonia oceanica to the daily fluctuations in the light environment, at contrasting depths. We assessed changes in photophysiological parameters, leaf respiration, pigments, and protein and mRNA expression levels. The results show that the diel oscillations of...
Sediment properties as important predictors of carbon storage in zostera marina...
Dahl, Martin; Deyanova, Diana; Gutschow, Silvia; Asplund, Maria E.; Lyimo, Liberatus D.; Karamfilov, Ventzislav; Santos, Rui; Bjork, MatsSeagrass ecosystems are important natural carbon sinks but their efficiency varies greatly depending on species composition and environmental conditions. What causes this variation is not fully known and could have important implications for management and protection of the seagrass habitat to continue to act as a natural carbon sink. Here, we assessed sedimentary organic carbon in Zostera marina meadows (and a...
