Fertilization decreases species diversity but increases functional diversity: A three-year experiment in a Tibetan alpine meadow

Popis výsledku v původním jazyce

The link between biodiversity and grassland productivity remains a central puzzle for both theoretical and applied ecologists. Little is known about the response of functional diversity (FD, i.e. the extent of trait differences between organisms in a given community) to increased grassland productivity following fertilization. Species diversity is often used as a surrogate for FD but evidence shows that FD is often independent from species diversity. We conducted a three-year (2004-2006) experiment in aTibetan alpine grassland to examine the effect of fertilization on FD and SD, and its relationship with productivity. We measured specific leaf area, plant height and seed size for 32 species in control, low- and high-fertilization treatments over threeyears, and quantified three components of FD: functional richness (FRic), functional evenness (FEve) and functional divergence using Rao's index (FDrao). While SD decreased rapidly, as expected, both FRic and FDrao increased significantl
