37 species of amphibians have already been extinguished; Understand the reasons
According to the International Union for Nature Conservation (IUCN), more than 1500 to 900 animal species have been declared extinct; Most people are classified as “extinct.” Among them, dozens of species Amphibians, currently considered the most endangered vertebrates on the planet.
Like other animals, amphibians play the basic role in nature dynamics, especially Water and Geological ecological systems.
For example, frog mosquito carnivores, The scorpionSpiders and other animals that can transmit disease. Furthermore, Environmental Quality Bio Indicators are consideredBecause its existence (or absence) reflects the balance of the environment they live in.
What is amphibians?
To be considered as an amphibious animal, it belongs to one of the three orders of the amphibious class:
- Anura: frogs, frogs and frogs;
- Cadata: Salamandras and Trisions;
- Gymnophiona: Snake snakes (Cicilia).
Anura can develop and jump the paws behind the animals. People with cadet order are elongated with the tail and moves similar to lizards. Finally, gymnophiona has a cylindrical body, without pavs and resembling worms or snakes.
In fact, some of these animals Are studying by industry PharmaceuticalThis is because they produce secretions that are likely to develop drugs.
These secretions are also used in the cultural rituals of various domestic traditions. An example is the giant Macaco (Philomedisa Bicolor), Usually the Amazon tribes are used and this is called Cambbe – In these rituals, your secretion is applied to small skin burns.
How many amphibians are extinct?
According to the company Amfibiweb, More than 8,800 species Amphibious Already listed worldwide. In Brazil, the list published by the Ministry of Environment in 2022 indicates that 1,188 species were recorded in the national territory.
Published in late 2023, the world amphibians describe it Completely extinct amphibian species confirmed in nature. In addition, two more species disappeared from nature and only living in captivity.
In more than eight thousand known species, 41% Will be extinctAnd there is not enough data of over 900 people so that their extent is assessed. In the case of climate change, 846 is threatened by increased temperature, residential change and other environmental impacts.
Amphibianly intentions
Currently, amphibians are considered the most intimidated vertebral group on the planet, with almost half extinct. Although 41% of amphibians face somewhat threat, this percentage is about 26% of mammals and 15% between birds.
The main cause of the extent of amphibians is the loss of natural habitatsThe use of tropical forests, pesticides, lakes and rivers, and other human activities.
“The main threat to the damage and decline of the habitat is the main threat to amphibians, which affects 2,686 threatening species. The land is rapidly eradicating the land for timber production, but the agricultural and urban expansion is replacing the key to amphibious habitats,” the world said.
Second, the Climate change indicates a serious riskSince these animals are very sensitive to variations in temperature and humidity – factors can be changed mostly by the effects of greenhouse gases.
The third largest threat diseases.
Other factors that contribute to the degeneration of amphibians are hunted by increased burning, invasive species, and using these animals for gastronomic, inal shadow or pets.
