Colombian Plump Frog

<em>Elachistocleis pearsei</em>, commonly known as the Colombian Plump Frog, is an amphibian species belonging to the genus <em>Elachistocleis</em> within the family Microhylidae, a globally distributed group of small to medium-sized frogs. This species is assessed as Least Concern by major conservation bodies, indicating that its populations are currently stable and not at elevated extinction risk. It has been documented in Colombia and Venezuela, where it inhabits freshwater-associated environments, moist forests, and wetland habitats. Microhylid frogs of this genus are typically burrowing or semi-fossorial, often emerging to breed in temporary pools following heavy rainfall. They are characterized by their rounded, inflated body form, which provides the basis for the common name. Dietary information specific to this species has not been documented, though microhylids frequently specialize in consuming ants and termites. Biological traits of this species remain poorly documented in the scientific literature. The persistence of <em>Elachistocleis pearsei</em> is dependent on the maintenance of humid lowland habitats in northern South America.

Oso Polar

El mayor carnivoro terrestre de la Tierra, el oso polar puede superar los 700 kg y se encuentra en el hielo marino del Artico, desde Canada hasta Rusia. Es un mamifero marino altamente especializado que depende del hielo marino para cazar focas anilladas y barbadas. Excelente nadador capaz de cubrir grandes distancias en agua abierta. Clasificado como Vulnerable, sus poblaciones soportan una presion severa por la rapida perdida de hielo marino artico debida al cambio climatico.
