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.

coastal hook moss

Sanionia orthothecioides, the coastal hook moss, is a pleurocarpous moss in the family Scorpidiaceae distributed across Arctic and subarctic coastal regions of Norway, Sweden, and adjacent high-latitude environments. Mosses in the genus Sanionia are characteristic components of moist Arctic tundra, snowbed communities, and coastal habitats where they form extensive carpets in areas of persistent soil moisture near snowmelt or coastal spray. Sanionia orthothecioides grows in dense cushions or mats on wet rocks, coastal cliff ledges, soil banks, and peatlands in the low Arctic and subarctic zones, tolerating periodic inundation, salt spray exposure, and freeze-thaw cycles that characterize coastal high-latitude environments. Like other mosses, it lacks true vascular tissue and absorbs water and nutrients directly through leaf surfaces, making it sensitive to desiccation but resilient to temporary submersion. Arctic and subarctic mosses are ecologically critical components of tundra carbon cycling, accumulating organic matter in cold, wet conditions and contributing substantially to the global peat carbon pool. Sanionia orthothecioides is classified as Least Concern by the IUCN, being widely distributed across coastal Arctic regions and not currently threatened by any major population-level pressures.

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.
