- Habitat Loss and Extinction in the Hotspots of Biodiversity
The more likely possibility is that our knowledge of threat to plant, reptile, and amphibian species is insufficient and that many more species are threatened than are currently on the red lists For reptiles 253 species are threatened, 20% of those species assessed, whereas for amphibians 124 species are threatened, 25% of those species

Global Amphibian and Reptile Decline Collectively, amphibians and reptiles are the most threatened vertebrate group on Earth According to the International Union for Conservation of Nature (IUCN), as of 2008, 42% of amphibian species showed evidence of decline, and 32% were globally threatened (Critically Endangered, Endangered or Vulnerable categories) or extinct (IUCN amphibian assessment)
- Conserving Critical Amphibian Habitat - The Conservation Fund
Wyoming Toads: One of the Most Endangered Amphibians in North America The Wyoming toad was truly on the brink of extinction several decades ago With only 10 individual toads remaining and the species on the Federal endangered species list, scientists and conservationists banded together to save them
- Amphibian Decline or Extinction? Current Declines Dwarf . . .
Amphibian declines and extinctions are critical concerns of biologists around the world The estimated current rate of amphibian extinction is known, but how it compares to the background amphibian extinction rate from the fossil record has not been well studied I compared current amphibian extinction rates with their reported background extinction rates using standard and fuzzy arithmetic
- A quarter of sharks and rays threatened with extinction | IUCN
A quarter of the world’s sharks and rays are threatened with extinction according to The IUCN Red List of Threatened Species™, with ray species found to be at a higher risk than sharks The findings are part of the first ever global analysis of these species carried out by the IUCN Shark Specialist Group (SSG)
- One-quarter of freshwater animals at risk of extinction, new . . .
Overfishing and the introduction of invasive alien species have had a particularly strong role in driving extinctions Although the threatened freshwater animals studied tend to live in the same areas as threatened amphibians, birds, mammals and reptiles, they face different threats due to their specific habitats
- One Quarter of Freshwater Animals at Risk of Extinction
One Quarter of Freshwater Animals at Risk of Extinction The largest global assessment of freshwater animals on the IUCN Red List of Threatened Species to date has revealed that 24% of the world’s freshwater fish, dragonfly, damselfly, crab, crayfish and shrimp species are at high risk of extinction, according to an analysis published in Nature
