Common Metad

The Common Metad (<em>Millardia meltada</em>) is a rodent belonging to the genus <em>Millardia</em> within the family Muridae. As a member of the Old World rats and mice, this species is typically found in diverse terrestrial and aquatic ecosystems across its range. The Common Metad is classified as Least Concern on the IUCN Red List, indicating that its populations are currently stable and not facing immediate extinction risk. Detailed biological traits such as body length, weight, and lifespan have not been widely documented for this species in available records. Its taxonomy places it within the order Rodentia, which encompasses a broad array of gnawing mammals adapted to a wide variety of ecological niches. While specific dietary habits are not well characterized in the available data, members of the genus <em>Millardia</em> are generally understood to be omnivorous, feeding on plant material and invertebrates typical of their habitat. Ongoing monitoring is important for ensuring this species maintains its current conservation standing.

Mariposa Monarca

Uno de los insectos migratorios mas notables del mundo, las mariposas monarca realizan migraciones de ida y vuelta de varias generaciones de hasta 4.800 km entre las areas de cria en el norte de America del Norte y los sitios de hibernacion en los bosques de montana de Mexico. Sus brillantes alas naranja y negro advierten a los depredadores de su toxicidad, derivada de las plantas de algodonillo que consumen como orugas. Amenazada, las poblaciones invernantes han disminuido mas del 80% desde la decada de 1990 debido a la perdida del habitat del algodonillo, los pesticidas y el cambio climatico.
