Clinton's bulrush

Clinton's Bulrush, Schoenoplectus clintoni, is a perennial wetland sedge in the family Cyperaceae with a restricted distribution in parts of the northeastern United States, named in honor of DeWitt Clinton, an early American naturalist and statesman. Like other bulrushes in the genus Schoenoplectus, it grows in shallow water and wet soils at the margins of lakes, ponds, marshes, and slow-moving streams. The stems are triangular or round in cross-section, bearing clusters of small, brownish spikelets characteristic of the genus. Bulrushes provide critical ecosystem services in wetland habitats, stabilizing shorelines, filtering water, providing nesting cover for marsh birds, and furnishing food through their seeds and starchy rhizomes for waterfowl and mammals. Clinton's Bulrush is considered rare within its limited northeastern range and faces threats from wetland drainage, development, and invasive species including common reed (Phragmites australis) that displace native emergent vegetation. Wetland loss across the northeastern United States has significantly reduced the area of suitable habitat for specialist wetland plants. The species is protected or of concern in several states where it occurs.

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.
