Red List assessment of amphibian species of Ecuador: A multidimensional approach for their conservation.
Ecuador is one of the most biodiverse countries in the world, but faces severe pressures and threats to its natural ecosystems. Numerous species have declined and require to be objectively evaluated and quantified, as a step towards the development of conservation strategies. Herein, we present an u...

(ii) Supporting the ex/in-situ conservation programs to protect species considered like Critically Endangered and Endangered.
