Cistícola de Chubb

Chubb's Cisticola (Cisticola chubbi) is a small, streaked warbler-like bird in the large African genus Cisticola (family Cisticolidae), named for the British naturalist Charles Chubb. It inhabits montane grasslands and forest margins in the highlands of sub-Saharan Africa, with populations recorded from the mountains of eastern and central Africa including the Albertine Rift region, Ethiopia, and Uganda. Like most cisticolas, C. chubbi is a non-migratory resident of open grassy habitats, where males produce characteristic repeated calls from elevated perches during the breeding season. The species is assessed as Least Concern by the IUCN, reflecting its wide distribution across African highland grasslands and the absence of evidence for major population declines. Its diet consists primarily of insects and small invertebrates gleaned from grass stems and the ground surface. Cisticola taxonomy has been subject to extensive revision, and the chubbi species group includes several geographically distinct forms that may represent separate species. Habitat degradation from overgrazing, agricultural encroachment, and scrub invasion into montane grassland represents a long-term threat to the species and its associated grassland community across its African range.

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.
