Detailed explanation-1: -Edge Effect – The greater number of landscape elements, vegetation complexity and mixed ecosystem characteristics result in greater density and biodiversity along the ecotones. This phenomenon is called the edge effect.
Detailed explanation-2: -Edges become areas with increased noise, light, pollution, human recreation and roadkill. The increased noise, light and human activity may cause some species to move further inland, away from habitat edges.
Detailed explanation-3: -Examples include open corridors cleared for roads in woodlands and hedgerows established in grasslands. Negative edge effects include increased risk of parasitism or disease, increased risk of predation, adverse microclimate conditions, and competition from invasive species.
