In biology and ecology, extinction is the end of existence for a group of organisms according to a taxon, usually a species. A species or subspecies is considered extinct when there is strong evidence that the last individual died. The point of extinction is generally considered to be the death of the last individual of that group or species, although the ability to reproduce and recover may have been lost before that point. Because the potential range of a species can be so great, timing of extinction is difficult and is often done in a way that goes back to the past. This difficulty leads to Lazarus taxon, an extinct species that suddenly "resurfaces" (usually in fossils) after a period of apparent absence. The bad impact of humans as well as the change of nature and the environment are gradually pushing more and more animal species to the brink of extinction. The following article of Toplist introduces animals that have become extinct in the past 10 years.
Bermuda Saw-whet Owl
This species of owl lives in Bermuda. However, due to rapidly declining numbers of cedars and palm trees, the arrival of non-native predators and competitors, the Bermuda Saw-whet owl gradually became extinct. rare and extinct. Bermuda is a species of owl that is endemic to Bermuda. It is described from fossil records and explorers' accounts of this bird in the 17th century.
The cause of its extinction is unknown, but it may be related to the decline of cedars and old trees, or the emergence of non-native predators and competitors. land after human invasion. First described in 2012, it was declared extinct in 2014.
Taiwanese leopard
The Taiwanese leopard, also known as the Formosan cloud leopard, is a subspecies of clouded leopard, living in Taiwan and endemic to the island of Taiwan. They have cloud-shaped markings on their fur. Their fangs are larger than those of other feline animals. Good climbing ability, squirrel-like agility similar to South American wildcats. Their diet consists of large terrestrial mammals, but mostly arboreal mammals, such as gibbons, macaques or monkeys, other mammals such as deer, hedgehogs or birds and livestock, they like to hunt by surprise attack by jumping down from trees and grabbing their prey. They usually live in tropical and subtropical forests. They are considered to have a very important position in the culture of the Taiwanese aborigines, the Rukai, because they are very proud to wear a leopard print coat. By 2013, this animal was extinct due to large and indiscriminate logging of natural forests, gradually robbing them of their habitat.
Clouded leopards are endemic to the island of Taiwan and may have disappeared forever. Taiwan Island is the only place where people can see Formosan cloud leopards, so the possibility of people seeing Formosan cloud leopards is very low. It is conjectured that some Formosan cloud leopards may still be alive, but the likelihood of humans seeing them in large numbers is very low. Conservationists say poaching and deforestation are the two main reasons for the rapid decline of Formosan leopards. Animal experts from the US and Taiwan have been searching for the Formosan cloud leopard since 2001, but they haven't found any. To find them, they installed about 1,500 infrared cameras and smell traps in the mountains of Taiwan. A stuffed leopard can now only be seen in the Taiwan Museum. Two other clouded leopards live in the Taipei Zoo, but they were imported from Southeast Asia.
Pinta Island Turtle
Pinta Island Turtle or Abingdon Island Turtle is one of 11 subspecies of the Galápagos tortoise complex - animals endemic to the Galápagos Islands. The last individual of this subspecies is a male tortoise called the lonely George. In the last years of his life, the lonely George was considered the rarest creature in the world and a prominent symbol of efforts to protect the environment in the Galápagos in particular and internationally in general. This large tortoise is a subspecies of the Galápagos tortoise complex - animals endemic to the Galápagos Islands that inhabit Pinta Island, Ecuador. After people began to set foot and dominate this island, Pinta turtles began to be overhunted until the last turtle, Lonesome George, died and this animal was officially extinct. strains in 2012.
For several decades, efforts to breed George's subspecies failed, most likely due to the lack of a female of this subspecies, so the Darwin Center researchers came up with a solution. $10,000 reward for anyone who finds a matching female turtle for George. On July 21, 2008, it was reported that George had unexpectedly mated with one of the female turtles, a total of 13 eggs were obtained and they were immediately placed in the incubator. However, on 11 November, the Darwin Center confirmed that 80% of the eggs had problems and by December the remaining eggs were also unable to hatch, X-ray examination revealed that they were damaged.
West African Black Rhino
Native to Africa, the West African black rhino is a very rare rhino subspecies of the black rhino. This species has a large body with a length of 3-3.8m, a height of 1.4 - 1.7m and weighs 800 - 1,300kg. It has two horns: the first and second horns have a length of 0.5 - 1.3 m and 2 - 55 cm, respectively. It once inhabited the west-central African savanna until the International Union for Conservation of Nature declared the West African black rhino extinct in 2011 due to brutal poaching. , cruel, cruel human. This subspecies was hunted in the early 20th century, but their numbers increased in the 1930s after conservation action was taken.
As protection efforts have declined over the years, the population of the Western black rhino has increased. By 1980, the number had reached hundreds. Poaching continues and in 2000 it was estimated that only 10 individuals survived. In early 2006, during an intensive survey of northern Cameroon (the last remaining habitat of other species) no one were found, but efforts to locate any individuals were found. Surviving continues. Illegal poaching and limited anti-poaching efforts have led to the decline of this subspecies. No animals are known to be held in captivity. In 2011, it was declared extinct.
Yangtze River Dolphins
The Yangtze River Dolphin, also known as the Yangtze River Goddess or the White Fin Dolphin, is an endemic river dolphin, once living in the lower Yangtze River, China. But then, over time, due to human impact, industrialization, hydroelectricity, fishing, this fish species gradually decreased in number. Many efforts have been made to conserve this species, but an expedition in late 2006 confirmed no individuals were found in the river. Yangtze River Dolphin, also known as the Yangtze River Goddess or Whitefin Dolphin - Populations of this species plummeted during the period of industrialization in China and the excessive use of the river for fishing, trading and fishing. waterways and hydroelectricity.
Many efforts have been made to conserve the species, but a late 2006 expedition found no individuals in the river. Since this species has been declared extinct, it is considered the first mammal to become extinct since the Japanese sea lion and Monachus tropicalis went extinct in the 1950s. species in the well-studied Extinct Whale order directly influenced by humans. In August 2007, a Chinese man recorded a large white animal swimming in the Yangtze River. While it is expected that the animal on the video may be a baiji, the mere presence of one or a few species, especially in the age of technology, is not enough to save this partially extinct species. from true extinction. The last baiji named Qiqi died in 2012.
Pyrenean mountain goat Ibex
The Pyrenean ibex mountain goat is one of four subspecies of the Spanish wild goat (also known as the Iberian wild goat), which inhabits the Iberian peninsula. This species was most common in the Cantabrian Mountains, southern France and in the northern Pyrenean Mountains. After that, it was the next victim of over-hunting that led to extinction in 2000. Currently, science is trying to research in the hope of being able to revive this animal. There are many theories about the evolution and migration history of C. pyrenaica into peninsular Spain. Scientists, including paleontologists and geneticists, should continue to search for paleontological, phylogenetic, and other evidence to uncover molecular connections between species. different subspecies.
Understanding the species' history could help scientists better understand how the wild goat species, C. pyrenaica affects the region, and could provide a new understanding of the relationship between these species. subspecies. It is possible that C. pyrenaica evolved from a related ancestor to C. caucasica from the Middle East at the "early of the last ice age (120-80 thousand years ago)". C. pyrenaica most likely moved from the northern Alps and passed through southern France into the Pyrenees at the beginning of the Magdalenian period about 18,000 years ago. If this were true, then C. caucasica praepyrenaica may have been more distinct from the three other wild goat species that scientists now know of that inhabited the peninsula of Spain.
Above are the animals that have become extinct in the past 10 years. Through the above article, we can see that there are quite a few animals that have to disappear because of the greed and cruelty of humans. We are gradually destroying the existence of many other species in the world and this is worthy of condemnation!
