Christmas Cactus

The Christmas cactus (Schlumbergera kautskyi) is a species of epiphytic cactus in the family Cactaceae, endemic to a restricted area of the Atlantic Forest in the state of Espírito Santo, Brazil. It is one of the lesser-known species in the genus Schlumbergera, which contains six to nine species depending on the taxonomic treatment applied. Like its congeners, Schlumbergera kautskyi is an epiphyte of humid montane forests, growing on tree branches and rocky outcrops at intermediate elevations where moisture is consistently available. The flattened, jointed stems are adapted for photosynthesis and water storage. The species produces tubular flowers with reflexed petals, characteristic of the genus, which are pollinated by hummingbirds. Its highly restricted natural range makes it particularly vulnerable to habitat loss. The Atlantic Forest of Brazil has been reduced to less than twelve percent of its original extent, and the remaining fragments face ongoing pressure from agricultural expansion, urban development, and logging. Schlumbergera kautskyi is poorly known in horticulture compared to the more widely cultivated Schlumbergera truncata and Schlumbergera bridgesii, but has been of interest to breeders and collectors. Its conservation status requires regular monitoring given the ongoing decline of its native habitat.

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.
