| Abstract | Recent
declines in arthropod diversity, abundance and biomass are central to
the global biodiversity crisis. Yet, we lack a mechanistic understanding
of the respective contributions of species richness, species identity
and abundance to overall biomass change, and how the environment filters
these processes. Synthesizing 11 years of data from a biodiversity
experiment and from farmed grasslands in central Europe across a
gradient of plant species richness and land-use intensity, we show that
local arthropod biomass declines were predominantly (>90%) linked to
species richness losses. Abundance declines among persisting species
accounted for only 5–8% of lost biomass. The role of species identity
depended on the environment and diminished over time: especially under
high plant diversity and low land-use intensity, arthropod species with
both below-average total biomass and above-average individual biomass
(large, rare species) contributed disproportionately to species
turnover—but this was only detectable in early years when the
communities were still relatively abundant. We conclude that arthropod
communities are currently homogenizing towards few common species of
similar biomass, probably reducing their adaptability to future
environmental change. Increasing the diversity and reducing the land-use
intensity of grasslands may mitigate ongoing community simplification
and loss of arthropod diversity and functioning. |
