Habitat & Geographic Range

Newtonia Común

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found in Norway.

Lobo gris

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, deserts and xeric shrublands, and tropical and subtropical dry broadleaf forests, among 13 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (Japan), Europe (5 countries), North America (7 countries), Oceania and the Pacific (Marshall Islands, Vanuatu), and South America (5 countries). Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Newtonia Común

<em>Newtonia brunneicauda</em>, the common newtonia, is a small passerine bird in the family Vangidae, endemic to the island of Madagascar. This insectivorous bird typically inhabits humid and subhumid forests, forest edges, and secondary vegetation in the eastern and northern parts of Madagascar. <em>Newtonia brunneicauda</em> forages actively in the mid-storey and understorey, gleaning insects and other small invertebrates from foliage and branches. Its geographic range is largely restricted to Madagascar, though occurrence data in the source records lists Norway, which may reflect a sampling artifact rather than the species' actual distribution. The species is currently assessed as Least Concern by the IUCN, with populations considered relatively stable despite ongoing forest loss in Madagascar. Biological traits such as lifespan, body size, and diet remain poorly documented at a population level for this species. The common newtonia is a characteristic component of Madagascar's endemic forest bird community and is considered an indicator of relatively intact forest habitat. Its conservation is linked to the preservation of Madagascar's remaining tropical forests, which face significant pressure from slash-and-burn agriculture and timber extraction.

Lobo gris

El lobo gris (Canis lupus), el cánido silvestre más ampliamente distribuido, se extiende desde América del Norte a través de Eurasia en hábitats diversos que incluyen la tundra, bosques y praderas. Son animales altamente sociales que viven en manadas familiares lideradas por una pareja reproductora dominante. Como depredadores clave, los lobos regulan las poblaciones de presas y moldean profundamente la estructura del ecosistema, como demostró su reintroducción en Yellowstone. Antes muy perseguidos, las poblaciones se están recuperando en muchas regiones.
