Habitat & Geographic Range
Clay Crest
Typically found in virtually all terrestrial and freshwater habitats.
Distributed across Belgium, Denmark, Norway, and Sweden.
Polar bear
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.
Found in Norway. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.
Clay Crest
Clay-crest, Malacothrix saxatilis, is a perennial herb in the family Asteraceae native to coastal bluffs, chaparral, and rocky slopes of California and Baja California in the western United States and Mexico. The species forms sprawling to semi-erect stems with deeply lobed, grayish-green leaves and bears numerous pale white to cream-colored, dandelion-like flower heads with finely fringed ray florets. The common name refers to the chalky or clay-colored appearance of the foliage, which has a grayish, mealy texture due to fine pubescence. Clay-crest is characteristic of dry, rocky habitats, particularly coastal sage scrub and chaparral communities on calcium-rich soils of the California Floristic Province, one of the world's recognized biodiversity hotspots. The species is drought-tolerant, producing much of its growth and flowering during the cooler, wetter months of the California winter and spring before entering summer dormancy. Pollinators including bees and butterflies visit the flowers. Malacothrix saxatilis has several recognized varieties adapted to slightly different microhabitats along the Pacific coast. The species is not currently listed as threatened at the global level, though coastal development and habitat fragmentation threaten some local populations within the California Floristic Province.
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.
