Range

Widely distributed across Africa (South Africa), Asia (Japan, Taiwan), Europe (11 countries), North America (Canada, United States), Oceania and the Pacific (Australia), and South America (Brazil, Chile).

Polar bear

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.

arabidópsis

<em>Arabidopsis thaliana</em>, commonly known as common wall cress or thale cress, is a small annual flowering plant in the family Brassicaceae native to Eurasia and Africa, and now naturalized in North America, Australia, and other temperate regions worldwide. The species has become one of the most important model organisms in plant biology and genetics, owing to its small genome size, short generation time of approximately six weeks, prolific seed production, and ease of laboratory cultivation. <em>Arabidopsis thaliana</em> was the first plant to have its complete genome sequenced, in 2000, revolutionizing our understanding of plant molecular biology, development, and physiology. In nature, it typically grows in rocky outcrops, disturbed sandy soils, walls, roadsides, and waste ground, tolerating poor nutrient conditions and a wide range of climates. The plant produces a basal rosette of small ovate leaves, followed by an erect flowering stem bearing tiny white four-petaled flowers and slender silique seed pods. Despite its modest appearance, <em>Arabidopsis thaliana</em> has facilitated thousands of scientific discoveries in plant genetics, epigenetics, and stress responses. The species is currently assessed as Least Concern by the IUCN. Biological traits such as average lifespan, plant height up to 30 centimeters, and seed output are well-characterized in laboratory settings.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
