Fluvial biogeomorphic succession model.
(a) Approximate placement of the six sites of two study areas (floodplain forest and salt marsh) along the gradient of fluvial biogeomorphic succession (FBS), (b) Simplified version of the FBS model developed by Corenblit et al. [10,23].
Fig 2.
Representation of bi-variance (β+γ+δ+ζ, all in %) and tri-variance (δ, in %) in vegetation–soil–topography relationships.
Symbols, α, ε, and η, represent uni-variances. The three circles here are of the same size because the corresponding three singular axes have been standardized (see text).
Fig 3.
Elevation (m above sea level) range of each site of two study areas (floodplain forest and salt marsh).
Fig 4.
Proportion (%) of variances estimated from the relationships among the first singular axes of vegetation, soil, and topography, identified by 3-B PLS for the floodplain forest data (a–c) and for the salt marsh data (d–f).
The three circles of each site are of the same size because the corresponding three singular axes had been standardized before estimating the proportions.
