Excelsheet	Variable	Description
		
Water	Nutrients	Nutrient status. Contains 2 levels: "Y" = nutrient enriched; "N" = no extra nutrients added
	Temperature	Air temperature in climate-controlled rooms. Contains 2 levels: "25" = 25 C; "30" = 30 C
	Plant	Indicates the presence/absence of a mangrove seedling. Contains 2 levels: "Y" = yes; "N" = no
	Exp_unit	Unique identifier assigned to each experimental unit within experiment
	Treatment	Treatment to which black mangrove seedlings were exposed to: non-enriched, 25 C; enriched, 25 C; non-enriched, 30 C; = enriched, 30 C  
	DIC	Dissolved inorganic carbon (mg/L)
	TA	Total alkalinity (mg/L)
	pH	pH
	Week	Number of weeks relative to the start of the experiment (November 26, 2021)
	Type	Indicates the water fraction from which the sample was taken. Contains 2 levels: porewater and surface water
		
Nutrients	Nutrients	Nutrient status. Contains 2 levels: "Y" = nutrient enriched; "N" = no extra nutrients added
	Temp	Air temperature in climate-controlled rooms. Contains 2 levels: "25" = 25 C; "30" = 30 C
	Exp_unit	Unique identifier assigned to each experimental unit within experiment
	Treatment	Treatment to which black mangrove seedlings were exposed to: non-enriched, 25 C; enriched, 25 C; non-enriched, 30 C; = enriched, 30 C
	Week	Number of weeks relative to the start of the experiment (November 26, 2021)
	NH4	Ammonium concentrations in sediment pore-water (mg/L)
	NO3_NO2	Nitrate and nitrite concentrations in sediment pore-water (mg/L)
	PO4	Phosphate concentrations in sediment pore-water (mg/L)
	Type	Indicates the water fraction from which the sample was taken. Contains 2 levels: porewater and surface water
		
Seedling_growth	Nutrients	Nutrient status. Contains 2 levels: "Y" = nutrient enriched; "N" = no extra nutrients added
	Temperature	Air temperature in climate-controlled rooms. Contains 2 levels: "25" = 25 C; "30" = 30 C
	Exp_unit	Unique identifier assigned to each experimental unit within experiment
	Treatment	Treatment to which black mangrove seedlings were exposed to: non-enriched, 25 C; enriched, 25 C; non-enriched, 30 C; = enriched, 30 C
	Week	Number of weeks relative to the start of the experiment (November 26, 2021)
	Stem_length	Length of seedling stem from sediment surface to the highest apycal meristem from which the newest pair of leaves emerges (cm)
	Leaf_area	Total leaf area per seedling per date (cm2), calculated by inserting measured values of leaf width and leaf length into equation (see excelsheet "Leaf_area_equation") and subsequently summing up all leaf area values per seedling. All leaves per seedling were measured.

Leaf_area_equation	A training dataset consisting of the width (x1) and length (x2) of 30 randomly selected leaves of a known leaf area (y) was used to fit an equation of the type y=a+b*x1*x2. This equation was subsequently used to calculate leaf area from leaf width and length values throughout the experiment.
