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 oat

<em>Avena sativa</em> is a domesticated annual grass in the family Poaceae, cultivated worldwide as a cereal crop and fodder plant. Originally derived from wild oat ancestors in the Fertile Crescent, it is now grown across all major agricultural regions, including Africa, Asia, Europe, North America, Oceania, and South America. The species typically thrives in cool, temperate climates with moderate rainfall and is planted in grasslands, croplands, and disturbed habitats. It has been a staple food grain for millennia, valued for its nutritional content, including beta-glucan fiber, proteins, and minerals. Common oat typically grows to 60–120 cm in height and produces distinctive drooping panicle inflorescences bearing multiple spikelets. The species is cultivated both for human consumption and as livestock forage. Its conservation status has not been formally evaluated by the IUCN, reflecting its widespread cultivation and absence of extinction risk. Biological traits such as lifespan, length, and weight are not standardized in wildlife databases given its status as a crop species, and dietary characteristics remain poorly documented in ecological terms. It is one of the most economically important cereal grains globally and supports diverse agroecosystems.
