Global dataset on seagrass meadow structure, biomass and production

[摘要] Seagrass meadows provide valuable socio-ecological ecosystemservices, including a key role in climate change mitigation and adaption.Understanding the natural history of seagrass meadows across environmentalgradients is crucial to deciphering the role of seagrasses in the global ocean.In this data collation, spatial and temporal patterns in seagrass meadowstructure, biomass and production data are presented as a function of bioticand abiotic habitat characteristics. The biological traits compiled includemeasures of meadow structure (e.g. percent cover and shoot density),biomass (e.g. above-ground biomass) and production (e.g. shootproduction). Categorical factors include bioregion, geotype (coastal orestuarine), genera and year of sampling. This dataset contains dataextracted from peer-reviewed publications published between 1975 and 2020based on a Web of Science search and includes 11 data variables across 12seagrass genera. The dataset excludes data from mesocosm and fieldexperiments, contains 14 271 data points extracted from 390 publicationsand is publicly available on the PANGAEA ® data repository( https://doi.org/10.1594/PANGAEA.929968 ; Strydom et al., 2021). The top five most studied genera are Zostera , Thalassia , Cymodocea , Halodule and Halophila (84 % of data), and the least studied generaare Phyllospadix , Amphibolis and Thalassodendron (2.3 % of data). The data hotspot bioregion is the TropicalIndo-Pacific (25 % of data) followed by the Tropical Atlantic (21 %),whereas data for the other four bioregions are evenly spread (rangingbetween 13 and 15 % of total data within each bioregion). From the datacompiled, 57 % related to seagrass biomass and 33 % to seagrassstructure, while the least number of data were related to seagrassproduction (11 % of data). This data collation can inform several researchfields beyond seagrass ecology, such as the development of nature-basedsolutions for climate change mitigation, which include readership interestedin blue carbon, engineering, fisheries, global change, conservation andpolicy.
