The dbFD_new.R file is sourced from the main script and includes minor modifications to the <i>dbFD()</i> function in the <i>FD </i>package to account for missing cells when calculating functional diversity.</p> <p><b>Column metadata</b></p> <p><i>initial_species_data.csv</i></p> <p>id: the number of species (mono = 1, 3, 6, or poly = 9), the functional diversity treatment (low or high), and finally the replicate number (1-6).</p> <p>treatment: the level of functional diversity (individual species, low, high, or poly). ‘Low’ and ‘high’ values are followed by the number of species (3 or 6).</p> <p>block: experimental block.</p> <p>initial.fd: initial functional richness (min, low, high, or max).</p> <p>initial.gracilaria.biomass: initial wet weight of <i>Gracilaria </i>spp.</p> <p>initial.ampithoe.abund: initial abundance of Ampithoid spp.</p> <p>initial.bittium.abund: initial abundance of <i>Bittolium varium</i></p> <p>initial.callinectes.abund: initial abundance of <i>Callinectes sapidus</i></p> <p>initial.erichsonella.abund: initial abundance of <i>Erichsonella attenuata</i></p> <p>initial.fundulus.abund: initial abundance of <i>Fundulus heteroclitus</i></p> <p>initial.gammarus.abund: initial abundance of <i>Gammarus mucronatus</i></p> <p>initial.hippolyte.abund: initial abundance of <i>Hippolyte pleuracanthus</i></p> <p>initial.palaemonetes.abund: initial abundance of <i>Palaemonetes pugio</i></p> <p>initial.syngnathus.abund: initial abundance of <i>Syngnathus </i>spp.</p> <p>initial.callinectes.length: initial length of <i>Callinectes sapidus</i> (in mm)</p> <p>initial.fundulus.length: initial length of <i>Fundulus heteroclitus</i> (in mm)</p> <p>initial.hippolyte.biomass: initial biomass of <i>Hippolyte pleuracanthus</i> (in g)</p> <p>initial.palaemonetes.biomass: initial biomass of <i>Palaemonetes pugio</i> (in g)</p> <p>initial.syngnathus.length: initial length of <i>Syngnathus </i>spp. (in mm)</p> <p><i> </i></p> <p><i>final_species_data.csv</i></p> <p>date: date the sample was processed and weighed</p> <p>id: the number of species (mono = 1, 3, 6, or poly = 9), the functional diversity treatment (low or high), and finally the replicate number (1-6).</p> <p>group: the taxonomic group of the species (e.g., “Molluscs”, “Crustacean”, “Polychaete”,”Caprellids”) to be used in the calculation of ash-free dry mass from Edgar equations (see R script).</p> <p>Species: species whose dry mass whose abundance was recorded.</p> <p>8.0_mm: the number of individuals in the 8 mm sieve.</p> <p>5.6_mm: the number of individuals in the 5.6 mm sieve.</p> <p>4.0_mm: the number of individuals in the 4 mm sieve.</p> <p>2.8_mm: the number of individuals in the 2.8 mm sieve.</p> <p>2.0_mm: the number of individuals in the 2.0 mm sieve.</p> <p>1.4_mm: the number of individuals in the 1.4 mm sieve.</p> <p>1.0_mm: the number of individuals in the 1 mm sieve.</p> <p>0.71_mm: the number of individuals in the 0.71 mm sieve.</p> <p>0.5_mm: the number of individuals in the 0.5 mm sieve.</p> <p><i> </i></p> <p><i>final_afdm_data.csv</i></p> <p>date: date the sample was processed and weighed</p> <p>id: the number of species (mono = 1, 3, 6, or poly = 9), the functional diversity treatment (low or high), and finally the replicate number (1-6).</p> <p>species: species whose weight was recorded.</p> <p>number.length: the number of individuals or length (in mm) of the species in the sample.</p> <p>Tin: weight of drying tin by itself (g).</p> <p>Tin_Dry: weight of drying tin plus dried sample (g).</p> <p>Tin_Ash: weight of trying tin plus ashed sample (g).</p> <p>AFDM: ash-free dry mass (g) = (Tin_Dry – Tin) – (Tin_Ash – Tin)</p> <p>Notes: additional notes.</p> <p> </p> <p><i>trait_data.csv</i></p> <p>species: the species used in the experiment.</p> <p>armor: whether the organisms is defended.
