Choco Yellow-shouldered Bat

The Choco Yellow-shouldered Bat (Sturnira koopmanhilli) is a medium-sized frugivorous bat in the family Phyllostomidae, endemic to the Chocó biogeographic region of northwestern South America, where it occurs in the humid forests of the Pacific slope of Colombia and adjacent Ecuador. It belongs to the genus Sturnira — the yellow-shouldered bats — characterised by males bearing distinctive yellowish, orange, or reddish shoulder glands (from which the group's name derives), robust bodies, and rounded ears. Like all Sturnira, this species is primarily frugivorous, consuming a wide range of small, soft fruits from pioneer and forest trees, and plays an important role as a seed disperser in disturbed forest patches and forest edges. The diet of Solanaceae (nightshade family) fruits is particularly typical of the genus, and Sturnira bats are considered the primary dispersers of many pioneer Solanum species in Neotropical secondary succession, contributing directly to forest regeneration. The IUCN classifies the Choco Yellow-shouldered Bat as Data Deficient, reflecting significant uncertainty about the species' distribution limits, population size, and ecological requirements. The Chocó region continues to experience rapid deforestation, which threatens frugivorous bat diversity even where individual species lack adequate data for formal threat assessment.

common fringe-rush

<em>Fimbristylis dichotoma</em>, commonly known as the common fringe-rush, is a sedge-like plant in the family Cyperaceae. It has a cosmopolitan distribution, occurring across Africa, Asia, Europe, North America, Oceania, and South America, making it one of the more broadly distributed species in its genus. The species typically inhabits a variety of open, disturbed, and wetland environments, including rice paddies, roadsides, stream margins, and grasslands. <em>Fimbristylis dichotoma</em> is an annual or perennial herb that typically forms tufted clumps and produces characteristic umbel-like inflorescences. It is assessed as Least Concern, consistent with its wide global distribution and adaptability to a range of habitat types. The species plays a role in colonizing disturbed soils and contributing to ground cover in open habitats. Biological traits of this species remain poorly documented in the scientific literature. Its tolerance of varied environmental conditions, including seasonal flooding and drought, contributes to its success across multiple continents and diverse ecological settings.
