Concealed Conebush

<em>Leucadendron cryptocephalum</em>, commonly known as the Concealed Conebush, is a flowering shrub in the family Proteaceae, endemic to the Cape Floristic Region of South Africa—one of the world's most botanically diverse and threatened biodiversity hotspots. The genus Leucadendron comprises dioecious woody plants in which male and female flowers are borne on separate individuals, with females typically developing cone-like seed heads adapted for serotiny or animal-aided dispersal. <em>Leucadendron cryptocephalum</em> typically grows in fynbos shrubland, a fire-adapted Mediterranean-climate biome restricted to the Western Cape and Eastern Cape provinces of South Africa, where it occupies specific edaphic niches on well-drained, nutrient-poor soils. The species is currently classified as Endangered by the IUCN, reflecting severe habitat loss driven by agricultural expansion, urban development, invasive alien plant encroachment, and altered fire regimes that disrupt the natural regeneration cycle of fynbos vegetation. As a Proteaceae member, it plays a role in fynbos food webs by providing nectar for specialist sunbirds and insects. Population size and trend data remain limited, but ongoing habitat transformation in the Cape Floristic Region continues to threaten its long-term survival.

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.
