Root traits and decom­pos­i­tion rates

Fine-root decom­pos­i­tion is an import­ant determ­in­ant of nutri­ent and car­bon cyc­ling in grass­lands, but little is known about the factors con­trolling inter­spe­cific root decom­pos­i­tion. By study­ing 18 Mediterranean herb­aceous spe­cies from dif­fer­ent life his­tor­ies and taxo­nomic groups, Birouste et al. demon­strate that the poten­tial decom­pos­i­tion rate of fine roots is affected by root chem­ical com­pos­i­tion but not by mor­pho­lo­gical traits. Patterns of root traits, includ­ing decom­pos­i­tion rate, mir­ror those of leaves, res­ult­ing in a sim­ilar clus­ter­ing of species.
