Root system investigation in sclerophyllous vegetation: An overview

Abstract

Sclerophyllous vegetation contributes to the formation of forest resources in the Mediterranean biome that in turn provides an important resource in terms of ecosystem services. Despite this, scientific knowledge of sclerophyllous vegetation, in particular with regard to their root systems, is fragmented. This review takes into account the research on below-ground sclerophyllous biomass in different contexts where there is a Mediterranean climate. In particular, the authors analyse the different investigative approaches used in studying roots, the main topics covered by research, and the relationships between root and shoot biomass. The review shows that there is a paucity of research on the root systems of sclerophyllous vegetation although there are examples of innovative technologies being applied to research questions. This review considers some key works in the literature, and provides useful information to address re-vegetation and reforestation programmes in the context of Mediterranean ecosystems. © G.
