“…Some authors emphasize the presence of 'edge' species, which are mostly restricted to or spend most of their time in ecotones (Odum 1959;Aspey 1976). In the present study, however, no such 'edge' species were found.…”

Three-dimensional dispersion of drosophilid flies was studied within a secondary broad-leaved forest in relation to forest structure. The survey area included the forest margin and old canopy gaps and varied in the foliage height profile from place to place. Using multivariate analyses on the data of drosophilid dispersion, five microhabitats which were different from one another for drosophilids were recognized: (i) canopy layer; (ii) middle layer; (iii) floor layer of forest interior; (iv) upper layer of forest margin; and (v) herbaceous layer of forest margin and gap. The height of living space of canopy species was remarkably lowered at the forest margin. The forest edge was richer in both numbers of individuals and species than the forest interior from the overlap of the grassland and the forest canopy subcommunities and the addition of invaders from other habitats. However, no 'edge' species, which were mostly restricted to or spend most of their time in ecotones, were found. It is hypothesized that the above-ground forest structure consists fundamentally of three zones: (i) the canopy; (ii) the floor; and (iii) the edge. A significant positive correlation was found between the foliage height diversity and the degree of vertical habitat segregation among drosophilid species. The patchiness of vegetation structure influential to the three-dimensional dispersion in a forest drosophilid community was estimated to be on the scale of 110-450 m 2. This scale of subjective habitat patchiness or 'ecological neighbourhood' corresponds well with the most prevalent size of canopy gaps occurring in various forests.

“…Although this is an important concept in community ecology, there is controversy over the validity of evidence from natural conditions (e.g. Aspey 1976;Cady et al 1980;Kroodsma 1987 and references therein). One reason for the controversy is a difference in the method used to evaluate the edge effect.…”
