Here, we show that temperate forests also exhibit community-wide flowering at the regional scale. Annual seed-production records for seven dominant tree species across 432 forest sites, analysed with timescale-explicit wavelet metrics, reveal landscape-scale synchrony structured by two periods — a 2–4-year band and a 5–8-year band — and associated with spatially coherent summer temperatures. This dual-band synchrony demonstrates that large-scale, cross-species reproductive alignment is an emergent property of temperate forest communities, implying shared climate cueing of reproduction and the potential for community-wide predator satiation. Since $\\sim$2005, the short- and long-period synchrony has weakened, and the short-period signal has shifted towards $\\sim$2 years (shorter period). Species-specific shifts in timescale structure no longer sum constructively, implying smaller, less predictable resource pulses at the community level, reduced community-wide predator satiation, and a decoupling of consumer–resource dynamics under continued warming.\nhttps://doi.org/10.32942/X2W08Q\nEcology and Evolutionary Biology, Life Sciences\nMoran effect, mast seeding, spatial synchrony, seed production, community ecology, resource pulses, climate synchrony\nPublished: 2026-02-03 10:20\nLast Updated: 2026-02-03 10:20\nCC BY Attribution 4.0 International\nConflict of interest statement:\nnone\nLanguage:\nEnglish","source_license":"CC-BY-4.0","license_restricted":false}
