Abstract

This document describes the schema available from the APD namespace. The APD offers detailed descriptions for more than 500 plant trait concepts. It includes trait focused on plant morphology, plant nutrient concentrations, plant physiology, plant life history, and plant fire response. The definitions will be useful to researchers from diverse disciplines, including plant functional ecology, plant taxonomy, and conservation biology. All trait concepts are supported by comprehensive metadata including trait descriptions, allowable trait values, allowable ranges, preferred units, keywords, references, and links to matches in a selection of trait databases. The traits describe here also fully support the AusTraits plant trait database, <doi.org/10.5281/zenodo.3568417>.

1. Introduction

The APD is a compilation of the traits concepts used by AusTraits, a database of Australian plant traits. APD includes definitions for nearly 500 traits pertaining to plant functional ecology and plant morphology. The metadata for each trait concept has been reviewed by multiple people. Metadata includes a trait definition, accepted units and ranges (for numeric traits), allowable values (for categorical traits), keywords and trait groupings to enhance trait findability, references, and links to identical/similar traits in other trait databases. APD will be published in a machine-readable format (rdf representation), allowing the traits to be readily re-used by other databases. This is a human-friendly output, with embedded links to the references, other trait databases and keywords/concepts borrowed from other ontologies.

The APD is a community resource and we welcome any suggestions for edits, including additional key references for each trait or other trait databases for which we should add links.

2. Trait groups

The APD Trait groups express broad trait groupings, with each trait concept mapped into one or more trait groups as narrower concepts.

description	A root system morphology trait [TO:0000985] which are categorical [STATO:0000252] trait values that capture the branchiness [PATO:0002009] and texture [PATO:0000150] of the root system [PO:0025025] and the root system depth [TO:0001058]. Categorical root system descriptions that indicate the branchiness and texture of the root system and the depth of the root system.
comments
value type	categorical variable
has narrower	root_system_classification_type_i The primary root is fibrous or fleshy and is relatively long; mesophytic. root_system_classification_type_ii The primary root is relatively short and is fibrous. Roots are well branched in a dry habitat but branch little in one that is wet. root_system_classification_type_iii The primary root is usually long and fibrous. The first order lateral roots are well branched and are usually short; they are rather evenly distributed along the primary root; xerophytic. root_system_classification_type_iv The primary root is usually long and slender like that of Type II. The first order lateral roots are well branched. Those closest to the surface of the ground, or not far below, are relatively long; xerophytic and mesophytic. root_system_classification_type_v The primary root is divided-forked or branched-and fibrous, and with few first order lateral roots, or, in age, apparently with none; xerophytic. root_system_classification_type_vi The primary root is usually as in Type V. The first order lateral roots are mostly on the upper portion of the primary root and are thus relatively superficial; xerophytic or in well aerated sandy soil where the rainfall is not light. root_system_classification_type_vii Adventitious roots that are in one group and arise on a short horizontal, or vertical, axis of the shoot. They are fibrous or fleshly; mesophytic and hydrophytic. root_system_classification_type_viii Adventitious roots that are in one group and are fibrous and fleshy, or fibrous and thick. The fibrous adventitious roots are absorbing-anchoring roots and are usually with laterals to the second order; meophytic. root_system_classification_type_ix Adventitious roots that arise on the aerial stem and branches of some herbaceous taxa, shrubs, and trees; on creepers, vines, and runners; and on subterranean rhizomes and stolons.

description	A root system morphology trait [TO:0000985] which is a model parameter [STATO:0000034] indicating the distribution [PATO:0000060] of a plant’s roots [PO:0009005] with depth [PATO:0001595]. To calculate the model parameter, the required input is a plot of the cumulative root distribution from the surface, where [Y] is the cumulative fraction of roots from the surface to a depth [d]. An asymptotic nonlinear model is used to describe the vertical root distribution: Y = 1 - b^d where Y is the cumulative root fraction from the surface to soil depth d in centimeters and b the estimated parameter. Root biomass depth distribution coefficient (‘B’ from Gale & Grigal 1987), where high values indicate that root biomass is allocated deeper in the soil.

description	A fruit morphology trait [TO:0002629] which is the thickness [PATO:0000915] of the entire pericarp [PO:0009084] (the exocarp [PO:0009085], mesocarp [PO:0009087], and endocarp [PO:0009086] combined), although it often refers just to the fleshy [PATO:0002351] components of the pericarp (most frequently the exocarp and mesocarp). Fruit wall thickness of a mature fresh fruit. This term sometimes applies explicitly to the entire pericarp (exocarp + mesocarp + endocarp), but more frequently will have a functional meaning, referring to the outer fleshy layer which might be just some components of the peripcarp (most frequently the exocarp and mesocarp).

has narrower	dispersal_appendage_aril Fleshy outgrowth of a seed, that often attracts animals like birds or ants. dispersal_appendage_bristles Bristle-like projections. Trait value includes awns, which are slender, bristle-like projections in some grasses. dispersal_appendage_bracts_and_glumes When the bracts below the inflorescence are persistent and functional as dispersal appendages. This includes persistent glumes, the modified membranous bracts in the family Poaceae that surround the spikelet of a grass. dispersal_appendage_elaiosome Fleshy (often fatty) appendage on seeds that attracts ants. dispersal_appendage_fleshy_reward Broad term that includes a suite of appendages that provides a fleshy reward to attract dispersers; highest level of resolution available for some studies. dispersal_appendage_floating_seed Seed that is dispersed by floating on water. dispersal_appendage_flotation_scales Scales enhancing flotation, thereby assisting with dispersal. dispersal_appendage_floral_parts When some plant floral parts (the petals, sepals, or style) are persistent and aid in seed and fruit dispersal. This is a broad term not explicitly suggesting a dispersal mechanism. dispersal_appendage_hairs Modified hairs that aid in seed dispersal. dispersal_appendage_hooks A rear-facing point, as in a fish hook that aids in seed and fruit dispersal. dispersal_appendage_inflated_parts When some part of the seed, fruit, or associated tissues is inflated, aiding in seed or fruit dispersal. dispersal_appendage_none When a fruit and associated tissues lack any dispersal appendages. Includes exarillate and taxa with explicitly deciduous pappus. dispersal_appendage_pappus The calyx in Asteraceae that has been modified into bristles, hairs, scales or awns that are attached to the apex of the fruit. Taxa assigned this trait value have a persistent pappus that aids in dispersal, often, but not exclusively through wind dispersal. The pappus can also assist with flotation. dispersal_appendage_plumose Fruit, seed, style, or other floral component that is plumose and assists with dispersal. dispersal_appendage_receptacle Fleshy receptacle that aids in dispersal. dispersal_appendage_sarcotesta Fleshy seed coat that aids in dispersal. dispersal_appendage_spines Spines that aid in dispersal. dispersal_appendage_tumbleweed Plant growth form, whereby the aboveground plant component detaches from the roots and is readily rolled by wind across the ground, aiding in dispersal. dispersal_appendage_wings Referring to wing-like seed extensions that aid in wind dispersal. dispersal_appendage_wing_or_plume Broad term that includes a suite of appendages that aid in wind dispersal; highest level of resolution available for some studies.

URI	https://w3id.org/APD/traits/trait_0013114
alternative label	stem_vessel_diameter_hydraulic
description	A vascular tissue morphology trait [TO:0000470] which is a weighted arithmetic mean [STATO:0000398] diameter [PATO:0001334] of xylem vessels [PO:0025417] in a stem [PO:0009047], reflecting the greater relative contribution of wider vessels to hydraulic conductivity [EnvThes:22133] as described by the Hagen-Poiseuille equation [hupson:SCAIVPH_00000131] . Hydraulic diameter (or hydraulically weighted diameter) is a weighted arithmetic mean diameter of xylem vessels in a stem, reflecting the greater contribution of wide vessels to actual hydraulic conductivity. It is based on the Hagen-Poiseuille law, a fluid dynamics equation that describes laminar flow through a tube. It shows that a few large conduits transport an equal amount of water as many small ones, as flow rate is proportional to the 4th power of the conduit’s diameter.

It is recorded with a spectroradiometer [MOSAIC:00000974] and a higher value indicates a higher radiation use efficiency. Photochemical reflectance index measures plant responses to stress and the efficiency with which it uses photosynthetically active radiation, by indicating changes in carotenoid pigments in live foliage. It is calculated from the reflectance of radiation off the plant canopy at 531 nm (a xanthophyll band) and 570 nm (a reference band): PRI = (R531 - R570) / (R531 + R570), with a higher value indicating higher radiation use efficiency.

comments
value type	categorical variable
has narrower	plant_growth_form_herb A seed-bearing plant which does not have a woody above-ground stem; when available this term has been divided into more detailed terms. (Synonyms, forb) plant_growth_form_subshrub A plant that is only woody at the base, with the remainder of the stems regenerating yearly. This term is not meant to encompass short-lived plants that are only borderline woody. (Synonyms, suffrutescent) plant_growth_form_shrub A woody plant that is distinguished by NOT being a tree, due to one of more of the following characteristics, 1) they are less than 8 metres in height; 2) if a plant community includes trees, the shrubs are shorter than the surrounding trees and not part of the canopy; 3) in comparison to trees, the leaves are more distributed along the entire trunk; 4) the plant has multiple relatively narrow stems arising at or near ground level. The definition of shrub is complex, as there are many single-stemmed shrubs within Australia and many taxa that are described in the taxonomic literature as a shrub or small tree. plant_growth_form_mallee Refers to Eucalyptus species which are small trees that form a large lignotuber. They have multiple stems arising at or near ground level and regenerate from the lignotuber following fire. plant_growth_form_tree A tall, woody, perennial plant, usually with a single main trunk, and its leaves predominantly elevated above the ground surface. plant_growth_form_graminoid Herbaceous plant with a grass-like morphology that is within the order Poales. Taxa both with and without a tussock form are mapped to this term. This term is most frequently applied to three large monocot families, Poaceae, Cyperaceae, and Juncaceae, but the term could apply to other taxa within Poales with a grass-like morphology, including narrow, linear leaves and non-showy flowers, including Restionaceae, Centrolepidaceae, Anarthriaceae, and Ecdeiocoleaceae. Taxa outside Poales with a grass-like morphology should be designated as herbs and also have the term tufted mapped to the trait stem_growth_habit. plant_growth_form_tussock A subcategory of graminoid, which is a plant where many shoots from the basal meristem form prominent tufts. plant_growth_form_graminoid_not_tussock A subcategory of graminoid, indicating a plant which explicitly lacks a tussock morphology, with the leaves not growing in tufts. plant_growth_form_hummock Plant that grows as a dense mound up to 1 metre in height. The term generally applies only to species within the genera Triodia that form such mounds and these are considered a distinctive and uniquely Australian growth form. plant_growth_form_basal_large A plant whose leaves form a distinctly large basal tuft or rosette, including large acaulescent monocots and cycads. plant_growth_form_geophyte Subcategory of herb, specifically referring to plants that survive the winter/dry season as an organ (rhizome, bulb, corm, or tuber) buried in dry soil, with all leaves dying back each year. plant_growth_form_palmoid Plant that bears a rosette-like canopy of typically large, often compound leaves atop a usually thick (pachycaulous), columnar, unbranched or little-branched stem. Palms, tree ferns, trunked cycads, trunked grass-trees, and Pandanus are mapped to this term. (Synonyms, rosette-tree, palm, grass-tree) plant_growth_form_climber Plant that climbs up another plant’s stem or branches, rather than being able to support itself. Term used only if datasets do not specify if a climbing plant is herbaceous (a vine) or woody (a liana). plant_growth_form_climber_herbaceous Herbaceous plant that climbs up another plant’s stem or branches, rather than being able to support itself. This is usually synonymous with vine. Types of climbers (scrambling, twining) are captured under the trait plant_climbing_mechanism. (Synonyms, vine) plant_growth_form_climber_woody Woody or thick-stemmed (>2 cm) plant that climbs up another plant’s stem or branches, rather than being able to support itself. This is usually synonymous with liana. Woody climbers generally use hooks, tendrils, and/or adventitious roots to climb; the climbing mechanisms used by a taxon are captured under the trait plant_climbing_mechanism. (Synonyms, liana) plant_growth_form_fern A taxonomic grouping that includes acaulescent ferns; ferns are vascular plants that reproduce via spores and have neither seeds nor flowers. plant_growth_form_lycophyte A taxonomic grouping that includes quillworts, clubmosses, and spike mosses.
