gray wolf

O lobo-cinzento (Canis lupus), o canídeo selvagem mais amplamente distribuído, ocorre da América do Norte à Eurásia em habitats diversos, incluindo tundra, florestas e pradarias. São animais altamente sociais que vivem em matilhas familiares lideradas por um casal reprodutor dominante. Como predadores-chave, os lobos regulam as populações de presas e moldam profundamente a estrutura do ecossistema, como demonstrou sua reintrodução em Yellowstone. Antes muito perseguidos, as populações estão se recuperando em muitas regiões.
