Chungan Sucker Frog

The Chungan Sucker Frog (Amolops chunganensis) is a Least Concern torrent frog in the family Ranidae, endemic to central China, particularly associated with the mountains of Chongqing (formerly Chungan County, from which the species name derives) and surrounding areas. The genus Amolops, commonly known as torrent frogs or cascade frogs, is adapted for life in and around fast-flowing mountain streams, with expanded toe pads and sucker-like discs that allow clinging to wet, smooth rock surfaces in high-velocity water. Breeding occurs in stream environments, where males call from boulders at the stream edge and larvae develop in oxygenated torrent pools with specialized mouthparts for adhering to rock substrates. A. chunganensis inhabits subtropical and montane forests at elevations ranging from low to mid altitudes in Sichuan and Chongqing. The IUCN assesses this species as Least Concern, reflecting a relatively wide distribution within suitable stream habitats across central China. However, it faces ongoing pressure from water quality degradation, dam construction and stream modification, deforestation, and pollution from agricultural and urban runoff. Amolops frogs are sensitive to siltation and chemical contamination of breeding streams.

Common Starwort

<em>Stellaria graminea</em>, commonly known as the common starwort or lesser stitchwort, is a slender perennial herb in the family Caryophyllaceae, widely distributed across the temperate regions of Europe and Asia. This species typically inhabits grasslands, meadows, heathlands, woodland margins, roadsides, and hedgerow banks, favouring moderately acidic to neutral, nutrient-poor soils and tolerating a range of moisture conditions. Its geographic range extends from the British Isles and Scandinavia across continental Europe into Russia, Central Asia, and as far east as China and Japan, making it one of the more broadly distributed members of the genus. Classified as Least Concern on the IUCN Red List, <em>Stellaria graminea</em> remains common and stable across much of its extensive Eurasian range. The plant produces small white flowers with five deeply bifid petals, giving the appearance of ten petals, characteristic of the family Caryophyllaceae. Stems are typically weak and straggling, supported by surrounding vegetation, and reach lengths of approximately 15–60 cm. As a plant, dietary traits in the zoological sense are not applicable. Biological traits such as average individual lifespan, body weight, and precise dimensional measurements remain poorly documented, though the species is perennial and may persist at established sites for many years.
