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 Violet

<em>Viola odorata</em>, commonly known as the common violet or sweet violet, is a low-growing perennial herb in the family Violaceae native to Europe, western Asia, and North Africa, and now widely naturalized across temperate regions globally. This species typically inhabits woodland margins, hedgerows, shaded banks, meadows, and gardens, thriving in moist, humus-rich soils under partial to full shade. <em>Viola odorata</em> is one of the earliest spring-flowering plants in its native range, producing distinctive deep violet, occasionally white or pink, fragrant flowers from late winter through early spring. The characteristic sweet fragrance is produced by ionone compounds and has made this species extensively cultivated for use in perfumery, confectionery, and herbal medicine for centuries. The plant spreads vegetatively via stolons in addition to seed dispersal, enabling it to form dense ground-covering colonies in favorable habitats. The flowers and leaves are edible and have been used in culinary traditions across Europe as garnishes and salad ingredients. <em>Viola odorata</em> is an important early nectar source for bumblebees and other early-season pollinators. The species is currently assessed as Least Concern by the IUCN, with widespread and stable populations. Biological traits including average lifespan, plant height, and individual weight remain variable and are poorly documented in the scientific literature.
