Chong'an Moustache Toad

The Chongan Moustache Toad (Leptobrachium liui) is a robust, terrestrial frog in the family Megophryidae, native to the subtropical mountainous forests of south-central China, particularly the western Fujian, Jiangxi, and Sichuan provinces. Megophryid frogs are a diverse Asian family adapted to cool, humid forest streams, and many species display remarkable breeding biology. The moustache toad is best known for the extraordinary breeding biology of its congener Leptobrachium boringii — males of that species grow sharp, keratinous spines on the upper lip during the breeding season, used in aggressive fights over calling sites — and similar adaptations may occur in L. liui. Adults are cryptically coloured in browns and greys, resembling leaf litter. They breed in fast-flowing mountain streams, where females deposit large eggs in sheltered sites and the resulting robust, bottom-grazing tadpoles are well adapted to current environments. The IUCN classifies Leptobrachium liui as Least Concern with a broad enough range in montane forest habitats of central China to sustain viable populations. Threats include forest degradation, water pollution from agricultural runoff, and collection for the food and traditional medicine trades, which affect many frog species in China and Southeast Asia.

Cliff Mining Bee

The Cliff Mining Bee, Andrena species in the family Andrenidae, is a solitary ground-nesting bee that excavates tunnels in cliff faces, earthen banks, and compacted sandy or loamy soils, where the loose or friable substrates exposed in cliff profiles provide ideal nesting conditions. Mining bees in the genus Andrena are among the most species-rich solitary bee genera in the world, with hundreds of species across the Holarctic region, many narrowly specialized in their choice of pollen host plants. Female cliff mining bees construct vertical or angled burrows in cliff faces, with lateral cells off the main shaft, each containing a pollen ball and a single egg. Males are typically smaller and emerge before females to establish territories near nesting sites. Many Andrena species are oligolectic, collecting pollen from only a small number of plant species, making their populations sensitive to the availability of specific flowering plants in the landscape surrounding nesting areas. Cliff and bank nesting habitats provide well-drained, sun-warmed substrates essential for brood development. The loss of natural cliff faces and earthen banks to development, vegetation succession, and quarrying reduces available nesting habitat for cliff mining bees.
