Scenario tiger, lion, dragon, eagle disappear: why is that catastrophe?

In the US, Australia and many other countries, the sudden disappearance of the leading species of the food chain has caused a series of catastrophes.
In the natural world, animals and plants all exist in a close relationship with each other and obey the laws of nature to create a specific biome for each area.

This biome has a nutritional relationship to form a food web made up of many food chains and often there is only one leading predator in this food web, they play a very important role. important. This is a species (almost) not hunted and eaten by any species, for example: Tiger is the top predator in Asia, lion is the top animal in Africa, Komodo dragon dominates the island. Komodo, the Galapagos falcon is the top predator on the Galapagos Islands. Food net. Photo: Wiki Index But what happens when this top predator disappears from the food net or becomes weakened? This is a very interesting question! In fact, this hypothesis has happened many times and its devastating consequences are affecting the entire ecosystem. First, learn about the role of the top predator, which play an important role in maintaining ecological balance through controlling, overpowering, and regulating the numbers of other species. (from other predators to middlemen and also the flora at the bottom of the food web). Table top animals will help maintain ecological balance.

This protection not only takes place within the community, but also helps to control and repel exotic or invasive species outside the food web. The top predators also have an unwritten rule that they hunt only when hungry, not abuse their powers or abilities to slaughter smaller, weaker creatures. The end result is to create an ecological balance for the overall biome, so when the top predator is lost from the community, the community will fall into a disturbed and unbalanced state. . When the top species are gone There are many reasons that can cause the top species to be removed from the food net or lose the top position, one of the main reasons is due to human over hunting or the invasion of a birth. foreign objects are more overwhelming. The Everglades ecosystem, Florida, was once imbalanced by the dominant predator, the American short snout crocodile (Alligator mississippiensis), which was displaced by the exotic Burmese python (Python molurus bivittatus). Alligators are eaten by Burmese pythons. Photo: KPBS The flora and fauna here have been heavily damaged by this python, in contrast the number of Burmese pythons has increased exponentially (estimated from 30,000 to more than 300,000 individuals), making the import of this python species in the Ministry of the Interior. the US ban in January 2012. In Yellowstone National Park, starting in 1914, the wolves were massacred in an effort by Congress to protect the elk population as well as agriculture and cattle here. The results are not good either! The coyote heads the food net at Yellowstone. Photo: Untamed Science After the top predator was destroyed, the prairie wolves became the new top predator, but the problem was that the small grassland wolves were unable to take down their prey. big grass like moose. As a result, the elk population becomes crippled after the attacks, and the coyote wolves become more and more daring and more populous, killing smaller animals, eventually the people. gray wolves must be restored to maintain ecological balance. Another case took place in Australia. Here, the Dingo wild dog is a predator on the top ladder but has been severely reduced in number due to frequent crossbreeding with domestic dogs (they are listed as vulnerable species on the Red List. IUCN). Dingo wild dog. Photo: New Mails The decline in the power of the food-net leader has caused two invasive predators, the red fox and the wild cat, to self-destruct rodents and marsupials and birds to extinction (20 among the 30 extinct species in Australia are due to the predation of red foxes and feral cats). The above are just some examples of countless other cases that have happened in the past, through which we can see the indispensable role of the top and more conscious predator. in the protection of these animals.
