The Ribbed Newts is a group of three newt species:
The Iberian Ribbed Newt is the most common of the species, and the most frequently used as a model organism
by scientists. However, in the wild its numbers are declining, and in 2006 it became a near threatened
species. The other two species are in fact threatened, with P. nebulosus considered vulnerable to extinction
and P. poireti classified as an endangered species
. The numbers of all three species are declining in the wild. Livestock agriculture is an ongoing major cause of habitat loss and degradation, and of water pollution, for all three species.
