Endemic Mediterranean seagrasses poised to survive climate change challenges

This dataset contains in-situ metabolic measurements from benthic chamber
incubations conducted on Posidonia oceanica seagrass meadows in the
Tyrrhenian Sea (Civitavecchia, Italy) from February to October 2023. The
primary data file (Data.xlsx) includes seasonal measurements of community
respiration (CR), net community production (NCP), and gross community
production (GCP), expressed as dissolved oxygen fluxes (mmol O₂ g⁻¹ fresh
weight m⁻² d⁻¹), along with corresponding water temperatures (11–29°C) and
sampling dates. The repository also includes nine fully documented R
scripts that implement: (1) thermal performance curve (TPC) fitting using
the rTPC package with 999 bootstrap iterations for uncertainty
quantification; (2) spatial predictions of NCP across the Mediterranean
basin using Sea Surface Temperature data from Copernicus Marine Service;
and (3) ecosystem services calculations (oxygen production, CO₂
absorption, carbon fixation) under present and future climate scenarios
(RCP 4.5 and 8.5 for 2050). These data enable researchers to: reproduce
all analyses and figures from the associated publication; develop
alternative thermal performance models for P. oceanica; validate metabolic
predictions against independent datasets; and extend spatial projections
to other climate scenarios or time horizons. The standardized benthic
chamber methodology and comprehensive metadata facilitate comparisons with
seagrass metabolism studies from other Mediterranean locations. External
data sources (SST rasters, Posidonia distribution shapefiles) are
documented with access instructions but not included due to third-party
licensing.
