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.

Common Mint

Common Mint (<em>Mentha arvensis</em>), also known as corn mint or field mint, is a perennial herbaceous plant in the genus <em>Mentha</em>, family Lamiaceae. It is widely distributed across Africa, Asia, Europe, North America, and South America, with confirmed presence in countries including Belarus, Belgium, Brazil, Canada, and Czech Republic. Its range encompasses the Seychelles in Africa, four Asian countries, and ten European nations. The species is found across multiple habitat types, including tropical and subtropical moist broadleaf forests, dry broadleaf forests, and coniferous forests, occurring within at least four distinct biome types in the Indomalayan realm. Common Mint is classified as Least Concern on the IUCN Red List. As a member of the mint family, it typically produces aromatic foliage rich in menthol, and has historically been used in culinary and medicinal applications across many cultures. It typically spreads vegetatively through stolons and rhizomes in addition to producing seed. Detailed measurements of lifespan, length, and weight are not documented in available records.
