| 英文摘要 | Drought events are increasingly affecting the planet's biodiversity. While shrinking body size in response to drought has been observed in many vertebrate animals, whether this rule applies to microscopic animals and the mechanisms during this process remains largely unknown. To address this knowledge gap, we conducted a regional-scale investigation and a microcosm experiment to systematically evaluate the impact of drought stress on the body size of the most abundant soil animals on Earth - nematodes - across various biological scales, including community, population and individual levels. Our results showed that nematode body size declined with drought stress at all biological scales, including a community shift toward smaller-sized species, a smaller body size at the population scale, and a decrease in size-at-age of individuals. Additionally, we designed a Petri dish experiment to examine the reversible plasticity of body size under drought stress using a drought-tolerant nematode species. We found that while nematode body size could not be fully reversed when drought stress was alleviated in the offspring generation, offspring from parents that experienced severe drought conditions could acquire tolerance, leading to a relatively smaller reduction in overall body size compared to those from parents that suffered no or light drought conditions. Overall, our study suggests that the increasing frequency of drought events at the global scale will lead to a reduction in soil nematode body size, potentially causing far-reaching consequences for additional changes in the climate, as well as nutrient cycling in soils. |
