摘要: Abstract. Long-term human interactions with the natural landscape have produced a plethora of trends and patterns environmental disturbances across time space. Nitrogen deposition, closely tracking energy land use, is known to be among main drivers pollution, affecting both freshwater terrestrial ecosystems. We present statistical approach for investigating historical geographical distribution nitrogen deposition impacts accumulation on recent soil carbon-to-nitrogen ratios in Europe. After second Industrial Revolution, large swaths emerged characterized by different atmospheric caused industrial activities or intensive agriculture. affects C : N still recognizable way despite abatement oxidized reduced emissions during last 2 decades. Given seemingly disparate land-use history, we focused ~ 10 000 unmanaged ecosystems, providing evidence rapid response nature chronic supply through deposition.
