Common brighteyes

Common brighteyes (<em>Reichardia picroides</em>) is a perennial herb species found in Portugal, Sweden, and the United States, typically inhabiting diverse terrestrial environments across its range. As a member of the family Asteraceae, this species often produces yellow dandelion-like flowerheads and is commonly found in open, dry, and disturbed habitats such as roadsides, waste ground, and coastal areas. The common brighteyes has not been formally evaluated on the IUCN Red List. Originally native to the Mediterranean basin and parts of the Middle East, the species has spread to numerous other regions where it is considered naturalized. It typically grows in well-drained soils in full sunlight, showing a preference for rocky or sandy substrates in coastal and inland locations. The species is often associated with ruderal habitats and represents an adaptable pioneer in disturbed ecosystems. Biological traits of this species remain poorly documented in the scientific literature.

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.
