The geckos that live there experience more difficulties with reproduction and as a result are more at risk of population decline. [9] Many of the Mokopirirakau geckos are endangered. [8] Part of this is due to the effects of human activity and deforestation, but a huge contributor to this is predation of species in this genus. [15]
Limited research has been done on the southern even-fingered gecko due to the fact that the species is critically endangered. [4] The Gecko has only been captured once in recent years. In 2020 it was captured for the first time since 1963. [5] Conservation efforts are being put in place to mitigate the harm caused to the habitat of the gecko. [6]
Although trade in wild-caught turquoise day geckos is illegal, wild-caught geckos are commonly sold in pet shops. It is estimated that between December 2004 and July 2009, at least 32,310 to 42,610 geckos were taken by one collecting group, ~15% of the wild population at the time. [3]
One of the 25 most endangered primates. [7] Delacour's langur: Trachypithecus delacouri: 234–275 [8] CR [8] [8] The population of the species has radically decreased over the past decade. [8] Silky sifaka: Propithecus candidus: 250 [9] CR [9] [9] Estimate is believed to be a maximum. [9] Tonkin snub-nosed monkey: Rhinopithecus avunculus: 250 ...
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described. [11]
The table below shows that from 2020 to 2050 and beyond to 2100, the bulk of the world's population growth is projected to take place in Africa. Of the additional 1.9 billion people projected between 2020 and 2050, 1.2 billion will be added in Africa, 0.7 billion in Asia and zero in the rest of the world.
Endangered (EN) species are considered to be facing a very high risk of extinction the wild. In September 2016, the International Union for Conservation of Nature (IUCN) listed 382 endangered reptile species. [1] Of all evaluated reptile species, 7.4% are listed as endangered. The IUCN also lists nine reptile subspecies as endangered.
The crested gecko is now one of the most widely-kept and bred species of gecko in the world, second only to the common leopard gecko. [11] The crested gecko can be very long-lived. While it has not been kept in captivity long enough for a definitive life span to be determined, it has been kept for 15–20 years or more. [17] [7]
