  abstract = {{S}tudying the water transport in the soil-plant system requires information on the spatio-temporal variability of both subsystems and the ability to assess the impact of the soil heterogeneity and of the biological responses on the coupling between vegetation and its substrate. {T}his study was conducted for 2 years in a vineyard in the {A}ude {V}alley, {F}rance, by measuring the particle size distribution of the topsoil, the instantaneous isotopic ratios (18{O}/16{O}, 2{H}/1{H}) of leaf water, annual shoot biomass production, and interannual persistence of this biomass along a 360 m transect. {T}he resultant spatial series were analysed for their correlations and converted to spectra. {C}hanges in the isotopic ratios along the transect reflect the soil texture gradient, suggesting that the vines root deeper on the gravel layers than elsewhere. {T}his could provide a mechanism for the partial decoupling between soil and vegetation, and thus explain the strong temporal persistence of the vegetation pattern, the low overall correlation between biomass production and soil texture. {T}he spectra show that this correlation concentrates at specific scales which correspond to a minimum variability in the shoot biomass. {I}n this case, therefore, soil texture plays only a minor role in determining the spatial heterogeneity of shoot biomass in gravepine.
