AmphibiaWeb's goal is to provide a single page for every species of amphibian in the world so research scientists, citizen scientists and conservationists can collaborate. [1] It added its 7000th animal in 2012, a glass frog from Peru. [2] [3] As of 2022, it hosted more than 8,400 species located worldwide. [4] [5]
This found that 32% of species were globally threatened, at least 43% were experiencing some form of population decrease, and that between 9 and 122 species have become extinct since 1980. [3] As of 2010 [update] , the IUCN Red List , which incorporates the Global Amphibian Assessment and subsequent updates, lists 650 amphibian species as ...
The Iberian ribbed newt, gallipato or Spanish ribbed newt (Pleurodeles waltl) is a newt endemic to the central and southern Iberian Peninsula and Morocco. [2] It is the largest European newt species and it is also known for its sharp ribs which can puncture through its sides, and as such is also called the sharp-ribbed newt.
It has been projected in 2015 that many fish species will migrate towards the North and South poles as a result of climate change. Under the highest emission scenario RCP8.5, 2 new species would enter (invade) per 0.5° of latitude in the Arctic Ocean and 1.5 in the Southern Ocean. It woul also result in an average of 6.5 local extinctions per ...
The world's smallest known vertebrate, Paedophryne amauensis, sitting on a U.S. dime.The dime is 17.9 mm in diameter, for scale. The word amphibian is derived from the Ancient Greek term ἀμφίβιος (amphíbios), which means 'both kinds of life', ἀμφί meaning 'of both kinds' and βίος meaning 'life'.
Another factor that threatens the native axolotl population is the introduction of invasive species such as the Nile tilapia and common carp. These invasive fish species threaten axolotl populations by eating their eggs or young and by out-competing them for natural resources.
"Yellowstone" and the Duttons are almost back. Paramount Network announced in June that the second part of Season 5 will premiere on Sunday, Nov. 10 at 8 p.m. ET/PT. Internationally, the show will ...
As the discovery of new species is expected to continue (currently at about 20,000 per year), the encyclopedia will continue to grow. As taxonomy finds new ways to include species discovered by molecular techniques, the rate of new additions will increase, particularly in respect to the microbial work of (eu)bacteria , archaebacteria and viruses .
