The amount of forest edge is orders of magnitude greater now in the United States than when the Europeans first began settling North America. Some species have benefited from this fact, for example, the brown-headed cowbird , which is a brood parasite that lays its eggs in the nests of songbirds nesting in forest near the forest boundary.

The first is an edge effect. [13] This effect originates from the ignorance of interdependences that occur outside the bounded region. [13] Griffith [14] [8] and Griffith and Amrhein [15] highlighted problems according to the edge effect. A typical example is a cross-boundary influence such as cross-border jobs, services and other resources ...
A viewpoint dependent edge may change as the viewpoint changes, and typically reflects the geometry of the scene, such as objects occluding one another. A typical edge might for instance be the border between a block of red color and a block of yellow.
In English-language heraldry, the term a bordure diminished is occasionally employed – as in 'Or; a diminished bordure vert; on a chief indented azure, two fleurs de lys or' (127th Field Artillery, US), and 'Or; representations of two San human figures of red ochre, statant respectant, the hands of the innermost arms clasped, with upper arm ...
In geometry, an edge is a particular type of line segment joining two vertices in a polygon, polyhedron, or higher-dimensional polytope. [1] In a polygon, an edge is a line segment on the boundary, [2] and is often called a polygon side. In a polyhedron or more generally a polytope, an edge is a line segment where two faces (or polyhedron sides ...
Edge enhancement is an image processing filter that enhances the edge contrast of an image or video in an attempt to improve its acutance (apparent sharpness).. The filter works by identifying sharp edge boundaries in the image, such as the edge between a subject and a background of a contrasting color, and increasing the image contrast in the area immediately around the edge.
NBC News polling has also showed the border as one of Trump's strongest issues in the 2024 campaign. Democrats' new emphasis in their message marks a stark contrast from 2020 and 2016, when the ...
A boundary marker, border marker, boundary stone, or border stone is a robust physical marker that identifies the start of a land boundary or the change in a boundary, especially a change in direction of a boundary. [1] There are several other types of named border markers, known as boundary trees, [2] [3] pillars, monuments, obelisks, and ...
