The report estimates that there are 8 million animal and plant species on Earth, with the majority (5.5 million) represented by insects. Out of those 8 million species, 1 million are threatened with extinction, including 40 percent of amphibians, almost a third of reef-building corals, more than a third of marine mammals, and 10 percent of all ...
A 2013 study estimated that 670–933 amphibian species (11–15%) are both highly vulnerable to climate change while already being on the IUCN Red List of threatened species. A further 698–1,807 (11–29%) amphibian species are not currently threatened, but could become threatened in the future due to their high vulnerability to climate change.
[168] A 2019 study found that over 40% of insect species are threatened with extinction. [169] The most significant drivers in the decline of insect populations are associated with intensive farming practices, along with pesticide use and climate change. [170] The world's insect population decreases by around 1 to 2% per year. [171]
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
Habitat modification or destruction is one of the most dramatic issues affecting amphibian species worldwide. As amphibians generally need aquatic and terrestrial habitats to survive, threats to either habitat can affect populations. Hence, amphibians may be more vulnerable to habitat modification than organisms that only require one habitat type.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically ...
The species problem occurring in some cases due to natural hybridization, [41] cryptic species, [42] and natural evolution of species can be represented for species conservation by different approaches, such as multicriteria species approaches, [42] subspecies, evolutionarily significant units, distinct population segments or species-population ...
