Common Orange Daylily

<em>Hemerocallis fulva</em> is a robust, clump-forming perennial herb in the family Asphodelaceae, native to Asia and widely naturalized across Europe, North America, Australia, and parts of Africa and South America. It is recorded in Eswatini, six Asian countries, twenty-eight European nations, Canada, the United States, and Brazil. The species typically thrives in grasslands, wetlands, roadsides, forest edges, and cultivated landscapes. Its striking orange, trumpet-shaped flowers bloom in summer and are the source of its common name. Unlike most lilies, daylily blooms last only a single day, though multiple buds on each stem extend the flowering period. The species spreads primarily through rhizomes, forming dense colonies that can outcompete native vegetation in introduced regions. Its conservation status has not been formally evaluated by the IUCN. Flower buds, flowers, and young shoots of <em>Hemerocallis fulva</em> are used in East Asian cuisine and herbal medicine, though some concern exists about its mildly nephrotoxic properties in cats. Biological traits including average lifespan, body measurements, and dietary ecology remain poorly documented in standardized databases for this horticultural species.

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.
