asimina

<em>Asimina triloba</em> is a small deciduous tree in the family Annonaceae, native to eastern North America, with records from Canada and the United States, and naturalized or cultivated occurrences in Japan and São Tomé and Príncipe. It is the northernmost member of the predominantly tropical custard apple family and produces the largest edible fruit native to North America. The species typically inhabits rich, moist bottomland forests, stream banks, and shaded woodland understories, forming clonal thickets through root suckering. Its flowers are pollinated by carrion flies attracted to their fetid odor, and fruits are consumed and dispersed by large mammals. The large, elongated fruits have a creamy, banana-like flesh with a complex tropical flavor. The IUCN classifies this species as Least Concern across its native North American range. <em>Asimina triloba</em> serves as the sole larval host plant for the Zebra Swallowtail butterfly. Biological traits such as average lifespan, body measurements, and detailed dietary ecology remain poorly documented in standardized databases. It has gained increasing commercial interest as a cultivated fruit tree in organic agriculture and sustainable food systems.

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.
