Common Buckeye

The common buckeye (<em>Junonia coenia</em>) is a strikingly patterned butterfly found across North America, with documented occurrences in Canada and the United States. This species typically inhabits all terrestrial and freshwater environments across its range, favoring open, sunny habitats such as meadows, fields, roadsides, and coastal areas with low vegetation. It is classified as Least Concern on the IUCN Red List, reflecting stable and widespread populations. As a member of the family Nymphalidae, the common buckeye is instantly recognizable by the large, colorful eyespots on both the fore- and hindwings, which serve as a defense mechanism against predators. Larvae often feed on a variety of host plants in the families Plantaginaceae and Acanthaceae. The common buckeye typically undertakes seasonal migrations, moving southward in autumn and returning north in spring. Adults often nectar on a wide variety of wildflowers throughout their active season. Biological traits of this species remain poorly documented in the scientific literature.

koala

Icónico marsupial del este y sureste de Australia, los koalas pesan hasta 15 kg y pasan hasta 22 horas diarias durmiendo para conservar energía de su dieta de hojas de eucalipto, baja en calorías. Altamente especializados para procesar los compuestos tóxicos del eucalipto que matarían a la mayoría de los demás mamíferos, poseen microbiomas intestinales únicamente adaptados para la desintoxicación. Clasificado como En Peligro en 2022, con poblaciones diezmadas por la enfermedad de clamidia, la deforestación y el cambio climático.
