WebAug 30, 2016 · The lower boundary of the conifer–mountain meadow ecotone of the north-facing transect was, however, 200 m higher than the lower boundary of the corresponding ecotone on the south-facing transect. In addition to that, the vertical extent of the conifer–mountain meadow ecotone was somewhat greater on the south-facing transect. Webabundances at the ecotone boundary are the most commonly reported pattern in the literature, and may be explained by spillover at the boundary, the ways in which edges enhance hábitat quality, or by influencing resource availability and distribution (Hansen et al. 1992).
