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.

Monarch

Um dos insetos migratorios mais notaveis do mundo, as borboletas-monarca realizam migracoes de ida e volta de varias geracoes de ate 4.800 km entre as areas de reproducao no norte da America do Norte e os sitios de hibernacao nas florestas de montanha do Mexico. Suas brilhantes asas laranja e pretas alertam os predadores sobre sua toxicidade, derivada das plantas leiteiras consumidas como lagartas. Ameacada, com populacoes invernantes tendo diminuido mais de 80% desde a decada de 1990 devido a perda do habitat das plantas leiteiras, pesticidas e mudancas climaticas.
