Canadian beaver

O maior roedor da América do Norte, o castor-canadense pode pesar até 32 kg e é um mestre engenheiro do ecossistema, habitando rios, lagos e áreas úmidas do Canadá e norte dos Estados Unidos. Ao derrubar árvores e construir barragens de até centenas de metros de comprimento, os castores criam lagoas que proporcionam habitat para centenas de espécies. Suas tocas e canais transformam bacias hidrográficas inteiras. Quase caçados até a extinção por sua pelagem, as populações de castor se recuperaram fortemente.

Colonial Pine

<em>Araucaria cunninghamii</em>, the colonial pine or hoop pine, is a large coniferous tree in the ancient family Araucariaceae, native to Australia and also cultivated or naturalised in India, Libya, and South Africa. This species inhabits temperate and boreal forests at higher elevations, where it often forms a prominent emergent layer in subtropical and tropical rainforest communities in Queensland and New Guinea. Hoop pine is one of Australia's most commercially important softwood timber species, valued for its straight grain, durability, and workability. Trees can grow to considerable heights, with tall trunks characterised by horizontally spreading branch whorls that give the species a distinctive silhouette. <em>Araucaria cunninghamii</em> is assessed as Least Concern by the IUCN. The genus <em>Araucaria</em> has ancient origins, with fossil records extending to the Jurassic period, making it a living relic of Gondwanan flora. Seeds of hoop pine are consumed by birds and other fauna in its native range, contributing to limited seed dispersal. Biological traits of this species remain poorly documented in the scientific literature.
