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.

least weasel

A Doninha-comum (Mustela nivalis) está classificada como Quase Ameaçada (NT) na Lista Vermelha da IUCN. Está próxima de se qualificar como ameaçada, com populações que podem tornar-se vulneráveis sem ação de conservação.
