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?

Those living organisms that are flying, but that fly at low altitudes, those that do not bear much the increase in temperature, since being a steel barrier it is raising heat or increases the temperature on very hot days.

And also those organisms that depend on food that remain on the other side of the metal structure.

Explanation:

The United States - Mexico border wall (in English: Mexico – United States barrier) is a security fence built by the United States on its border with Mexico. Their goal is to prevent illegal immigration and drug trafficking into the United States. Its construction began in 1994, under the Bill Clinton government, under the program to combat illegal immigration known as Operation Guardian by Attorney General Janet Reno, but it took on more importance as it was an important component of campaign promises. of the candidate and today President Donald Trump. In 2017 it is formed by a physical barrier several kilometers long in the border area of Tijuana (Baja California) - San Diego (California). The wall includes three containment barriers, very high intensity lighting, motion detectors, electronic sensors, and night vision equipment connected to the US Border Police, as well as ongoing surveillance with off-road trucks and gunship helicopters. There are other sections of wall in the states of Arizona, Sonora and New Mexico.

Illegal immigrants (mainly from Mexico) try to cross from Mexico to the United States through more dangerous areas, such as the Sonora desert, which has resulted in more than 10,000 deaths since the beginning of its operation.

genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
