A 2021 study which analyzed around 11,500 freshwater fish species concluded that 1-4% of those species would be likely to lose over half of their current geographic range at 1.5 °C (2.7 °F) and 1-9% at 2 °C (3.6 °F). A warming of 3.2 °C (5.8 °F) would threaten 8-36% of freshwater fish species with such range loss and 4.5 °C (8.1 °F ...
Migratory fish populations have declined by 76% since 1970, and large "megafish" populations have fallen by 94% with 16 species declared extinct in 2020. [ 101 ] Marine species
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
Although the endangered species is protected, habitat loss from human development is a major reason for the loss of green turtle nesting beaches. Wetlands and marine areas have endured high levels of habitat destruction. More than 50% of wetlands in the U.S. have been destroyed in just the last 200 years. [8]
The chambo and kampango have been particularly overfished (the kampango declined by about 90% from 2006 to 2016, [47] O. karongae and O. squamipinnis by about 94%, and O. lidole might already be extinct [48] [49]) and they are now seriously threatened. [50] The IUCN recognises 117 species of Malawi cichlids as threatened; some of these have ...
Within cartilaginous fish, approximately 7 out of the 41 families of neoselachians (modern sharks, skates, and rays) disappeared after this event and batoids (skates and rays) lost nearly all the identifiable species, while more than 90% of teleost fish (bony fish) families survived.
In June 2019, one million species of plants and animals were at risk of extinction. At least 571 plant species have been lost since 1750, but likely many more. The main cause of the extinctions is the destruction of natural habitats by human activities, such as cutting down forests and converting land into fields for farming. [21]
The red kangaroo is the largest extant macropod and is one of Australia's heraldic animals, appearing with the emu on the coat of arms of Australia. [1]The fauna of Australia consists of a large variety of animals; some 46% of birds, 69% of mammals, 94% of amphibians, and 93% of reptiles that inhabit the continent are endemic to it.
