Responses of fluvial fish assemblages to agriculture within the boreal zone
Abstract The effect of agriculture on fish assemblages was assessed using electric fishing data from 108 sites on 27 medium‐sized rivers running through organic soils in central and northern Finland. The intensity of agriculture was quantified as the percentage of the catchment area used for agricul...
