In .some areas, the barrier built to prevent uncontrolled movement of people across the border between the United States and Mexico consists of miles of 6-meter-tall steel beams placed four inches apart. Discuss the ecological effects of such a barrier. What types of organisms would be most adversely affected by this habitat fragmentation?

Summary Introduction

To discuss: The ecological effects of manmade steel barriers between two countries.

Concept introduction:

In general, barriers mean limit or boundary. Ecological barriers are the natural limits that split one ecosystem from another ecosystem. These barriers are used for safety purpose. Some artificial barriers are also used to prevent the uncontrolled movement.

Explanation

In between the United States and Mexico, manmade barriers are built; they consist of steel beams of 6 meters long. These beams are placed at distance of 4 inches from each other to avoid the movement of larger animals such as black bears, bobcats, bighorn sheep, jaguar, ocelot, Mexican gray wolf, and puma...
