The role of the dodo in nature, and in what kind of environment can the dodo survive Urgent, thank y

A seemingly clumsy appearance of a bird with vestigial wings, originally lived happily on the island of Mauritius, due to the long-term isolation, to the strange visitors to warm and innocent hospitality, unexpectedly, people seem to be mistaken, thinking that the bird is an ignorant big stupid bird, breaking the previous quiet and peaceful life of the bird, ruthless humans and the animals brought by such as pigs, dogs, completely ravaged the living space of the bird, causing an indelible impact. Around 1681, the bird was declared extinct. This exhibition will take you to explore the exact nature of the bird and discuss the impact of the disappearance of the bird on the environment.

Long regarded as a big dumb bird, it weighs about 20 to 30 kilograms, has a large, hooked beak, and is adorned with bright feathers and a small tail, but it is easy to distinguish it from other birds for the simple reason that they cannot fly.

In 1598, Portuguese sailors landed on the island of Mauritius in the Indian Ocean and discovered that there was a unique and unknown bird living on the island.

Some people say that the birds evolved from an African fruit-eating Treron, they stopped on the island of Mauritus, because there were no other kinds of creatures at that time, and there was a lot of food around, they did not use their wings to fly in the sky to feed, and their wings naturally degenerated, and because they could not fly, their nests were naturally built on the ground. A person who has been to the island of Mauritius described the birds as stacking palm fronds of about 18 inches to protect their nests, and the incubation of eggs is done by both parents in turn, in fact, their young chicks are also capable of resisting invaders, but no matter how powerful they are, they cannot resist the attacks of intruders and their dogs, pigs and other domestic animals. Therefore, whether it is their eggs or themselves, they are used as sacrifices to the temple or destroyed, and there is another factor that makes the birds extinct, that is, the deforestation, which greatly reduces the food of the birds.

Race against crooked wolves.

Extinction means no effect.

No large carnivores, no rainforests with small rodents.

The dodo has been killed by humans ... Can't survive.

1. Genetic (genetic) diversity.

2. Species diversity and ecosystem diversity.

Consumer. It promotes the reproduction of the tree (because the dodo's digestive system muscles are strong enough to thin the seed coat of its seeds, Zeng Jin saw the documentary and learned that the tree would have gone extinct without the dodo).

At present, they are similar to ostriches, but Qingru has less muscle strength in the digestive system, and they are much weaker than dodos.

Go with the flow and don't interfere with nature's evolutionary process.

The dodo, also known as the Mauritian dodo, dove and lone pigeon, is a flightless bird found only on the island of Mauritius in the Indian Ocean. This bird was completely extinct due to human hunting and human activities in just 200 years after its discovery, and it can be called one of the most famous extinct animals after dinosaurs.

The dodo is larger than the spit-stolen chicken and weighs about 23 kilograms (about 50 pounds). The body plumage is blue-gray and the head is large. The mouth is 23 cm (9 in) long, pale black, with a pale red sheath forming a hook tip. Because the wings are small, they can't fly. The feet are strong,

The seeds of the Lu olive tree, because the seed shell of the Lu olive tree is very hard, it needs to be digested by the dodo before it can germinate, and with the extinction of the dodo, the seeds of the Lu olive tree can not germinate, and it also becomes extinct.

The Kawalian tree that grows on the island of Mauritius belongs to the Olive family, the Cavarian genus, is a tall tropical tree, the height of the tree can reach 30 meters, the circumference of the tree is 4 meters, most of them are century-old trees, although the tree bears fruit every year, that is, it does not grow seedlings, this mystery has been solved by scientists. It turned out to be related to the dodo. The dodo, which is 1 meter tall and can weigh up to 13 kilograms, can barely fly, became extinct as early as 1861.

Originally, the dodo liked to eat the fruit of the Valian tree, and the kernel could only germinate after the "thinning" of the bird's muscle stomach.
