dcterms:description
Objectives Although more than half of the Earth's landmass is covered by non-forest vegetation and forests only account for ca. 20%, the majority of wood anatomical and dendrochronological studies still centre on trees and their timber products of secondary meristem growth. Comprehensive assessments of the anatomy, taxonomy, physiology and dendrochronology of herbs are, however, still missing. We therefore aim to evaluate the importance of stem anatomical and dendrochronological aspects of herbaceous plants for vegetation science, and further intend to explore if species-specific differences in xylem anatomy can be linked with patterns of life form, plant size and site ecology. Locations Numerous extra-tropical sites within six biogeographic regions on six continents, spanning an elevational gradient of 4400 m from sea level to the alpine zone. Methods We employ the Xylem Database to investigate well-established and newly defined wood anatomical and dendrochronological traits in 3347 dicotyledonous tree, shrub and herb species from 140 families and 952 genera. The obtained site information is placed in a global context of vegetation cover. Results We demonstrate that plants included in the Xylem Database broadly represent the diversity of growth forms, habitats and life histories of extra-tropical dicots, thus validating its potential for a range of uses within vegetation science. An unexpectedly rich catalogue of xylem anatomical and dendrochronological features is found in the stems of almost all dwarf shrub and herb species, with the quantity and diversity of their characteristics being comparable to larger plants, including most tree species. Annual rings are formed independently of life form, plant size and site ecology. Secondary growth, which is an expression of plant age, defines the main principle of terrestrial angiosperm development.
