marreco

A marreca-garganey (Spatula querquedula) está classificada como Em Perigo (EN) na Lista Vermelha da UICN. Com alto risco de extinção em estado selvagem, com significativo declínio populacional e ameaças contínuas à sua sobrevivência.

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.
