Water‐saving strategies in rice farming entail cascading effects in prey–predator interactions across ecosystem boundaries

Journal of Applied Ecology, Volume 62, Issue 9, Page 2273-2282, September 2025.
These results show that introducing multiple drainage periods in rice fields (i.e. AWD) indirectly hampers terrestrial spider reproduction through limiting the emergence of potential preys from the aquatic to terrestrial boundaries. MSD resulted in a more conciliatory strategy as it largely reduces methane emissions and does not affect predator–prey ...
