Tlaconete diente espolón

The Claw-Toothed Salamander, Pseudoeurycea cephalica, is a lungless salamander in the family Plethodontidae endemic to the mountains of central Mexico, particularly the Trans-Mexican Volcanic Belt and adjacent highland ranges. As a member of the diverse plethodontid family, it breathes entirely through its moist skin and the lining of its mouth, requiring cool, humid microhabitats beneath rocks, logs, and moist leaf litter on forest floors. The species is relatively slender-bodied, with a long tail and well-developed limbs adapted for life in rocky montane terrain at elevations typically above 2,000 meters. Diet consists of small invertebrates including insects, worms, and arthropods found in the forest floor microhabitat. Reproduction in Pseudoeurycea species typically involves direct development, with eggs laid in moist terrestrial sites hatching as miniature adults rather than aquatic larvae, eliminating the species' dependence on standing water. The highland forests of central Mexico support exceptional salamander diversity, with many species narrowly endemic to individual mountain ranges or even single volcanoes. Deforestation, agricultural expansion, and climate change-driven upslope habitat contraction pose significant threats to highland salamander communities in Mexico. The conservation status of Pseudoeurycea cephalica is assessed as Endangered by IUCN due to ongoing habitat loss.

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.
