Colombian Oldfield Mouse

<em>Thomasomys dispar</em>, commonly known as the Colombian Oldfield Mouse, is a small rodent species belonging to the genus <em>Thomasomys</em> within the family Cricetidae. This species is classified as Data Deficient, indicating that insufficient information is currently available to evaluate its conservation status with confidence. It has been documented in Colombia, where it inhabits diverse terrestrial and aquatic-adjacent environments. Members of the genus <em>Thomasomys</em> are typically associated with high-altitude Andean habitats, including páramo grasslands, shrublands, and montane forest edges, where they occupy ground-level microhabitats and burrow in soft soils. These mice are generally omnivorous, consuming seeds, plant material, and invertebrates, though specific dietary data for <em>Thomasomys dispar</em> have not been recorded. Biological traits of this species remain poorly documented in the scientific literature. The Data Deficient classification highlights the need for targeted surveys in Colombian Andean regions to determine population size, distribution, and the ecological requirements of this poorly known rodent.

Monarch

One of the world's most remarkable migratory insects, monarch butterflies undertake multigenerational round-trip migrations of up to 4,800 km between breeding grounds in northern North America and overwintering sites in Mexican mountain forests. Brilliant orange and black wings warn predators of toxicity derived from milkweed plants consumed as caterpillars. Endangered, with overwintering populations having declined by over 80% since the 1990s due to milkweed habitat loss, pesticides, and climate change.
