Beyond leaf habit: generalities in plant function across 97 tropical dry forest tree species. New Phytol. 2021 Jun 25. doi: 10.1111/nph.17584. Epub ahead of print. PMID: 34171131. The compressed folder contains: - R studio project for analyzing the data associated with the present publication. - Scripts associated with each of the questions explored in the manuscript. - Question 1: whether patterns of trait variation varied consistently in relation to leaf habit and the ‘slow-safe versus fast-risky’ multivariate trait ordination - aim1_multivariate.R - aim1_univariate.R - Question 2: What are the main sources of trait variation? - aim2_site_comparison.R - aim2_var_part.R - Question 3: Do leaf habit classifications provide insight into plant community function by relating community weighted mean trait values to the proportion of deciduous species present in replicated forest plots across the sites? - aim3_functionalcomposition_deciduousness.R - Relationship between conductivity and leaf area: - Ks_LA.R - Sampling probabilities: - Sampling_Distributions_Overlaps.R - Data files used in the manuscript in comma separate values format (.csv), and their descriptions: - Community composition data: DryFourdom_matrix.csv - Columns: species 6 letter code, please see traits_dryfour.csv for the scientific name. - Rows: code for each plot at each of the four sites. CO: Colombia; CR: Costa Rica; MX: Mexico; PR: Puerto Rico. - Principal component analysis coordinates: PCA_coordinates.csv - Column A: row names to be imported into R with the 6 letter species code, please see traits_dryfour.csv for the scientific name. - Columns B to F: Each dimension from the principal component analysis. - Trait database for the 97 tree species: traits_dryfour.csv. Each column is described below: - sp_site: Six letter species code specific to a site if a species was sampled at different locations. - sp_code: Six letter species code, 3 letters from genus and 3 letters from specific epithet. - country: Country in which samples were collected. - site: Site where samples were collected. - family: Taxonomic family. - binomial: scientific name. - Leaf_habit: Deciduous, evergreen or semi-deciduous. - Leaf_type: If leaves are simple or compound. - n_PES_traits: Number of individuals used in the plant economic spectrum traits. - LA_cm2: Leaf area (cm2) - SLA: Specific leaf area (cm2 g-1). - WD: Wood density (g cm-3). - N.perc: Foliar nitrogen content (%). - C.perc: Foliar carbon content (%). - P.perc: Foliar phosphorus content (%). - n.pv: Number of individuals used in the pressure volume curves for TLP. - TLP.MPA: Leaf water potentia at turgor loss point (MPa). - n_k: Number of individuals used in the hydraulic conductivity measurements. - K: Hydraulic conductance (kg s-1). - Kh: Hydraulic conductivity (kg s-1 MPa-1). - Khs: Xylem specific hydraulic conductivity (kg m-1 s-1 MPa-1). - n_vl: Number of individuals used for vessel length measurments. - VL.cm: Vessel lenght in cm. - VL.SD: Vessel lenght standard deviation. - n_p50: Number of individuals for optical embolism measurements. - P50.MPa: The water potential at which 50 % accumulation of visual embolisms were observed in leaf veins (MPa). - n_hv: Number of individuals used in Huber Value measurements. - HV: The ratio between xylem area (m2) and leaf area (m2) for a given branch, known as Huber Value.
