Habitat & Geographic Range

Common Panicgrass

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Africa (Morocco), Asia (6 countries), Europe (33 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile).

Oso Polar

Habitat

Found across multiple habitat types including temperate broadleaf and mixed forests, temperate coniferous forests, and boreal forests and taiga, among 4 distinct biome types within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Panicgrass

<em>Panicum capillare</em> is an annual grass in the family Poaceae, native to North America and now broadly naturalized across Europe, Asia, Africa, Oceania, and South America. It is recorded in Morocco, six Asian countries, thirty-three European nations, Canada, the United States, Australia, Brazil, and Chile. The species typically colonizes disturbed habitats including roadsides, agricultural fields, riverbanks, waste ground, and sandy or rocky substrates with sparse vegetation. It produces an open, highly branched panicle inflorescence that detaches at maturity and disperses as a tumbleweed, facilitating long-distance seed dispersal. This adaptation contributes to its success as a colonizer of novel environments. Conservation status has not been formally evaluated by the IUCN, consistent with its status as a widespread, common, and often weedy annual species. Biological traits including average lifespan, body measurements, and detailed dietary ecology remain poorly documented in standardized ecological databases for this annual grass species. <em>Panicum capillare</em> plays a role in ruderal plant communities, providing food for granivorous birds and insects, though it is also considered an agricultural weed in crop systems across parts of its introduced 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.
