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 bee-brush

Common bee brush (<em>Aloysia gratissima</em>) is a flowering shrub native to a diverse range of terrestrial tropical and temperate habitats. Its documented range includes Brazil and South Africa, reflecting a disjunct distribution across the Southern Hemisphere. The plant is a member of the family Verbenaceae and is known for its small, fragrant white flowers that attract bees and other pollinators, lending it the common name bee brush. <em>Aloysia gratissima</em> typically grows in open scrublands, forest margins, and disturbed areas, often tolerating poor soils and variable moisture conditions. Its aromatic foliage has been used in traditional medicine and as a flavoring agent in certain regions. The species is generally drought-tolerant and may form dense thickets in suitable environments. Biological traits of this species remain poorly documented in the scientific literature.
