Monarch

Um dos insetos migratorios mais notaveis do mundo, as borboletas-monarca realizam migracoes de ida e volta de varias geracoes de ate 4.800 km entre as areas de reproducao no norte da America do Norte e os sitios de hibernacao nas florestas de montanha do Mexico. Suas brilhantes asas laranja e pretas alertam os predadores sobre sua toxicidade, derivada das plantas leiteiras consumidas como lagartas. Ameacada, com populacoes invernantes tendo diminuido mais de 80% desde a decada de 1990 devido a perda do habitat das plantas leiteiras, pesticidas e mudancas climaticas.

Polar bear

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.
