Properties of ecotones: Evidence from five ecotones objectively determined from a coastal vegetation gradient

Abstract: Abstract. Several properties have been suggested to be characteristic of ecotones, but their prevalence has rarely been tested. We sampled five ecotones to seek evidence on seven generalizations that are commonly made about ecotones: vegetational sharpness, physiognomic change, occurrence of a spatial community mosaic, many exotic species, ecotonal species, spatial mass effect, and species richness higher or lower than either side of the ecotone.The ecotones were in a sequence from scattered mangroves, through… Show more

“…Each fuelbed in the different biomes had different parameters assigned, such as plant species, fuel loading, percent of vegetation cover, etc., that were dependent on land cover information. As explained by Pettinari and Chuvieco [30], the limits of the different biomes in the Olson map are abrupt, and do not reflect the mosaics and ecotones that determine the gradual transition of vegetation cover between biomes [64]. This caused in some cases that adjacent pixels of a biome boundary had very different parameters in the fuelbed map, and this in turn caused that the fire behavior results were much different on either side of that boundary.…”

“…This includes biological productivity, genetic diversification, evolutionary adaptation, interspecific interactions, and the aggregation and movement of organisms, nutrients, and other materials (Risser, 1995), although a single ecotone may not exhibit all these characteristics (Walker et al, 2003). Another dimension of this rethinking of ecotones is their description as representing a spatial hierarchy (Gosz, 1991(Gosz, , 1993.…”

“…For each significant boundary identified with SMWA, the width and position of the associated ecotone was determined by moving window regression analysis (MWRA) (Hennenberg et al 2005;Walker et al 2003). This procedure computes the slope of a linear regression relating z-scores to transect position within a window drawn over five sampling points.…”
