Decline in amphibian populations. The Golden toad of Monteverde, Costa Rica, was among the first casualties of amphibian declines. Formerly abundant, it was last seen in 1989. Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world.
The average size of global wildlife populations have declined by 73% in 50 years, a new study by the World Wildlife Fund has found.. The study, titled the 2024 Living Planet Report, monitored ...
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. The Zoological Society of London (ZSL) manages the index in cooperation with the World Wide Fund for Nature (WWF). As of 2022, the index is statistically created from journal ...
Since the 1980s, decreases in amphibian populations, including population decline and localized mass extinctions, have been observed in locations all over the world. This type of biodiversity loss is known as one of the most critical threats to global biodiversity.
The world's animal species are dying, and humans are a big reason why. The World Wildlife Fund's Living Planet Report shows global populations of wild mammals, fish, birds, amphibians and reptiles ...
Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [2]
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 ...
Golden toad. The golden toad (Incilius periglenes) is an extinct species of true toad that was once abundant in a small, high-altitude region of about 4 square kilometres (1.5 sq mi) in an area north of the city of Monteverde, Costa Rica. [3] It was endemic to elfin cloud forest. [4] Also called the Monte Verde toad, Alajuela toad and orange ...
