Effects of landscape composition on predation rates at habitat edges

摘要: All landscapes are mosaics of habitat patches different types (Forman and Godron, 1981). Therefore, there will always be edges between in a landscape. These may associated with higher diversity plants animals, traditionally called an edge effect (Odum, 1971). However, the current use edge-effect concept summarizes diverse group phenomena that occur (Harris, 1988; Yahner, Angelstam, 1992). For example, interaction organisms living landscape mosaic sometimes cause effects related to (Janzen, 1986; Wilcove, McLellan Dobson, 1986). Predator—prey might edges. relationship predation rate depends on specific density potential nest predators, as well configuration Predators increase for several reasons. First, have prey predators view good foraging (Gates Gysel, 1978). Secondly, traveling lines (Bider, 1968; Chapter 4) therefore spend more time than other parts patch.
