| Abstract |
Climate variability threatens to destabilize
production in many ecosystems. Asynchronous species dynamics may buffer
against such variability when a decrease in performance by some species
is offset by an increase in performance of others. However, high
climatic variability can eliminate species through stochastic
extinctions or cause similar stress responses among species that reduce
buffering. Local conditions, such as soil nutrients, can also alter
production stability directly or by influencing asynchrony. We test
these hypotheses using a globally distributed sampling experiment. Grasslands in North America, Europe and Australia. Annual surveys over 5 year intervals occurring between 2007 and 2014. Herbaceous plants. We sampled annually the per species cover and
aboveground community biomass [net primary productivity (NPP)], plus
soil chemical properties, in 29 grasslands. We tested how soil
conditions, combined with variability in precipitation and temperature,
affect species richness, asynchrony and temporal stability of primary
productivity. We used bivariate relationships and structural equation
modelling to examine proximate and ultimate relationships. Climate variability strongly predicted asynchrony,
whereas NPP stability was more related to soil conditions. Species
richness was structured by both climate variability and soils and, in
turn, increased asynchrony. Variability in temperature and precipitation
caused a unimodal asynchrony response, with asynchrony being lowest at
low and high climate variability. Climate impacted stability indirectly,
through its effect on asynchrony, with stability increasing at higher
asynchrony owing to lower inter‐annual variability in NPP. Soil
conditions had no detectable effect on asynchrony but increased
stability by increasing the mean NPP, especially when soil organic
matter was high. We found globally consistent evidence that climate
modulates species asynchrony but that the direct effect on stability is
low relative to local soil conditions. Nonetheless, our observed
unimodal responses to variability in temperature and precipitation
suggest asynchrony thresholds, beyond which there are detectable
destabilizing impacts of climate on primary productivity. |
