edge effect

1. The occurrence of greater species diversity and biological density in an ecotone than in either of the adjacent ecological communities.

2. A phenomenon, such as a sandhi rule or cliticization, that happens at the edges of words, phrases, or other linguistic units.

edge effect

the occurrence of a greater diversity and density of organisms at a boundary between habitats.

The reduction of core area is directly related to the shape of a fragment since more irregular fragments are subjected to more matrix intervention and less protection of the interior environment, leaving the core more exposed to edge effects (Metzger, 2001).

Only a few studies have been conducted on the impacts of edge effects on birds in tropical rain forests (Varasteh et al., 2010; Rosli and Zakaria, 2011; Rosli et al., 2012) or on the effects of forest habitat fragmentation on bird distribution and diversity (Yahner, 2000; Maina, 2002).

The relationship between population density and distance from habitat edge varied between habitat types, indicating declining densities as distance into the cropland matrix increased and minimal edge effects in forest habitat.

Edge effects are a spatial phenomenon per se (Ewers and Didham 2006a); however, there are other underlying spatial effects on edge ecology.

The perimeter and the perimeter-area relationship are metrics that quantify and qualify the fragments in relation to the edge effect, which is an important aspect studied by ecological researchers because it may not guarantee the ecological stability of the fragment (VOLOTAO, 1998).
