Data from: Growing at the arid edge: Leaf anatomy variations are more extensive than stems in five Mediterranean species across contrasting moisture regimes-all the raw data of the anatomic measurements

# Growing at the arid edge: Leaf anatomy variations are more extensive than stems in five Mediterranean species across contrasting moisture regimes-all the raw data of the anatomic measurements [https://doi.org/10.5061/dryad.7pvmcvf2k](https://doi.org/10.5061/dryad.7pvmcvf2k) The dataset encompasses all the raw data collected during the study, comprising measurements and observations from both SA and MM sites across various plant species. ## Description of the data and file structure In the dataset, there is a single file containing comprehensive data pertaining to anatomical parameters across two distinct sites, SA and MM, and various plant species. Each row represents a specific measurement or observation, while the columns encompass diverse anatomical parameters. These parameters likely include but are not limited to stomatal density, stomatal length, Leaf Mass Area (LMA), lamina composition, quantification of leaf intercellular air spaces (IAS), and mesophyll cell area. ## Variables and Units The following table describes each variable in the dataset along with its units (if applicable). | Variable | Description | Units | | :------------------- | :-------------------------------- | :--------------------- | | Site | Study site location | - | | Species | Species name | - | | species(sc) | Species code | - | | sample | Sample identifier | - | | sp | Species abbreviation | - | | site2 | Secondary site identifier | - | | sn | Sample number | - | | SSn | Secondary sample number | - | | repeat | Repeat measurement indicator | - | | k | Specific identifier | extinction coefficient | | mode\_VL | Mode of VL (variable) | cm | | avg\_VL | Average VL | cm | | diameter | Diameter measurement | micrometers (µm) | | LMA | Leaf Mass per Area | g/m² | | A | Area measurement | cm² | | SD | Stomatal density | stomata/mm² | | VAm | Midrib Vessel's area | μm² | | VAsS | Stem Vessel's area | μm² | | IAS | Intercellular Air Space | % | | SM\_S | SM\_S (variable) | m² m-2 | | All Thickness (mic) | Total leaf thickness | micrometers (µm) | | Ad cut(mic) | Adaxial cuticle thickness | micrometers (µm) | | Ad apidermis(mic) | Adaxial epidermis thickness | micrometers (µm) | | Max palisade layers | Maximum number of palisade layers | layers | | Palisade max (mic) | Maximum palisade thickness | micrometers (µm) | | Mode palisade layers | Mode number of palisade layers | layers | | Palisade mode (mic) | Mode palisade thickness | micrometers (µm) | | Spongy (mic) | Spongy mesophyll thickness | micrometers (µm) | | Ab apidermis(mic) | Abaxial epidermis thickness | micrometers (µm) | | Ab cut(mic) | Abaxial cuticle thickness | micrometers (µm) | | Stom\_Leaf | Stomata number on leaf | - | | SL | Stomatal Legnth | micrometers (µm) | | Dm | Midrib vessels diameter | micrometers (µm) | | Ds | Stem vessels diameter | micrometers (µm) | | | | | | | | | | | | | | | | | ### Important Note on Missing Data There are some empty cells in the dataset. These empty cells are represented as "n/a" to indicate that the data was not available for those specific measurements. This notation helps minimize ambiguity for potential users.
