Typically found in diverse terrestrial and aquatic ecosystems.

Castor Americano

El roedor más grande de América del Norte, el castor canadiense puede pesar hasta 32 kg y es un maestro ingeniero del ecosistema que habita ríos, lagos y humedales de Canadá y el norte de Estados Unidos. Al talar árboles y construir presas de hasta cientos de metros de longitud, los castores crean estanques que proporcionan hábitat para cientos de especies. Sus madrigueras y canales transforman cuencas hidrográficas enteras. Una vez casi cazados hasta la extinción por su piel, las poblaciones de castor se han recuperado notablemente.

Gato Pajero

<em>Leopardus colocolo</em>, commonly known as the Colocolo, is a small wild cat species belonging to the genus <em>Leopardus</em> within the family Felidae. This species is assessed as Near Threatened by major conservation bodies, indicating that while it is not currently classified as threatened, its populations face pressures that could lead to a more serious conservation status if conditions worsen. The Colocolo inhabits diverse terrestrial and aquatic-adjacent environments across South America, where it is associated with grasslands, shrublands, and wetland margins. It is one of the smallest wild cats native to the continent. Specific country-level distributional records are not detailed in current documentation. Dietary information specific to this species has not been recorded in current records, though wild cats of similar size and habitat affiliation typically prey on small mammals, birds, and other small vertebrates. Biological traits of this species remain poorly documented in the scientific literature. Conservation concerns for the Colocolo include habitat loss, persecution by farmers, and the illegal wildlife trade. Continued monitoring and habitat protection are considered essential for maintaining viable populations.
