Corrigendum to: New handbook for standardised measurement of plant functional traits worldwide

Abstract

The authors regret that elements of Appendix 1 were incorrect in the original publication. The correct version of Appendix 1 is given below. Appendix 1. Summary of plant traits Summary of plant traits included in the handbookThe range of values corresponds to those generally reported for field-grown plants. Ranges of values are based on the literature and the authors' datasets and do not always necessarily correspond to the widest ranges that exist in nature or are theoretically possible. Recommended sample size indicates the minimum and preferred number of individuals to be sampled, so as to obtain an appropriate indication of the values for the trait of interest; when only one value is given, it corresponds to the number of individuals ( = replicates); when two values are given, the first one corresponds to the number of individuals and the second one to the number of organs to be measured per individual. Note that one replicate can be compounded from several individuals (for smaller species), whereas one individual cannot be used for different replicates. The expected coefficient of variation (CV) range gives the 20th and the 80th percentile of the CV ( = s.d. scaled to the mean) as observed in several datasets obtained for a range of field plants for different biomes. Numbering of plant traits corresponds with the numbering of the chapters in the handbook Abstract. Plant functional traits are the features (morphological, physiological, phenological) that represent ecological strategies and determine how plants respond to environmental factors, affect other trophic levels and influence ecosystem properties. Variation in plant functional traits, and trait syndromes, has proven useful for tackling many important ecological questions at a range of scales, giving rise to a demand for standardised ways to measure ecologically meaningful plant traits. This line of research has been among the most fruitful avenues for understanding ecological and evolutionary patterns and processes. It also has the potential both to build a predictive set of local, regional and global relationships between plants and environment and to quantify a wide range of natural and human-driven processes, including changes in biodiversity, the impacts of species invasions, alterations in biogeochemical processes and vegetation-atmosphere interactions. The importance of these topics dictates the urgent need for more and better data, and increases the value of standardised protocols for quantifying trait variation of different species, in particular for traits with power to predict plant-and ecosystemlevel processes, and for traits that can be measured relatively easily. Updated and expanded from the widely used previous version, this handbook retains the focus on clearly presented, widely applicable, step-by-step recipes, with a minimum of text on theory, and not only includes updated methods for the traits previously covered, but also introduces many new protocols for further traits. This new handbook has a better balance between whole-plant ...

Is the central‐marginal hypothesis a general rule? Evidence from three distributions of an expanding mangrove species, Avicennia germinans (L.) L

“…USA mangrove canopy heights decrease along temperature and precipitation gradients towards range margins . At these margins, A. germinans exhibit variation in xylem vessel architecture (Madrid, Armitage, & López-Portillo, 2014;Stuart, Choat, Martin, Holbrook, & Ball, 2007) (Jordan & Smith, 1995), reduced leaf area (Pérez-Harguindeguy et al, 2013), and reduced specific leaf area (Poorter, Niinemets, Poorter, Wright, & Villar, 2009); although similar traits are also consistent with drought resistance (Knight & Ackerly, 2003).…”

An extensive suite of functional traits distinguishes Hawaiian wet and dry forests and enables prediction of species vital rates

“…Leaf structure and composition traits were measured in three leaves per studied individual. Leaf saturated mass was measured using an percentage loss in area after drying (PLA dry ) as the per cent decline in area from saturated to dry leaves (Ogburn & Edwards, 2012;Pérez-Harguindeguy et al, 2013;Witkowski & Lamont, 1991).…”

“…We measured wood density (WD) from one 5-cm-branch segment of each of the studied individuals after bark removal by waterdisplacement (Pérez-Harguindeguy et al, 2013).…”

“…The concentration of leaf nitrogen, phosphorus, carbon per mass (N mass , P mass and C mass ) and carbon isotope ratio (δ 13 C) were determined using oven-dried leaves of three individuals per species by the University of Hawaii at Hilo Analytical Laboratory facility (Fry et al, 1996;Pérez-Harguindeguy et al, 2013). N mass and P mass were converted into N area and P area by multiplying by LMA.…”

Alien flora of Turkey: checklist, taxonomic composition and ecological attributes

“…In addition, growth form and life history were assigned according to the Thesaurus of Plant Characteristics for Ecology and Evolution (Garnier et al 2017) and other specific literature (Pérez-Harguindeguy et al 2016). Growth-forms reported for aquatic plants follow Brundu (2015).…”
