Since there would be less jaguars (predators) than other small animals (prey), there would be a decrease in biodiversity. Because the jaguar population would be less diverse, the jaguar populations would have a smaller gene pool, which would then lead to genetic drift. Thereafter, the jaguar population would be gone. Additionally, this new border fence would trap the jaguars and hinder their movement. Therefore, this allows for stricter control of the ecosystem, which means that the ecosystem would not develop naturally. This would also play a role in the biodiversity of the ecosystem. Consequently, it can be said that the border fence has disastrous effects on the jaguar
