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 Chinese Treefrog

<em>Hyla chinensis</em>, commonly known as the common Chinese treefrog, is an amphibian species found in Taiwan. It typically inhabits freshwater environments, moist forests, and wetlands, often occurring near ponds, streams, rice paddies, and other water bodies where it breeds during the warm season. The species is classified as Least Concern on the IUCN Red List, reflecting a currently stable population within its limited geographic range. Common Chinese treefrog belongs to the genus <em>Hyla</em> within the family Hylidae. It is a small, arboreal frog that typically spends much of its life in vegetation above ground, descending to water primarily to breed. Like other tree frogs, it possesses adhesive toe pads that facilitate climbing on smooth surfaces such as leaves and stems. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature. As an amphibian species, it is potentially sensitive to habitat loss, water pollution, and climate-related changes affecting its freshwater breeding habitats in Taiwan.
