Cliff Chirping Frog

The Cliff Chirping Frog, Syrrhophus marnockii (also known as Eleutherodactylus marnockii), is a small terrestrial frog in the family Eleutherodactylidae native to the Edwards Plateau and adjacent areas of central Texas in the United States and northern Mexico. This tiny frog, typically only 2–3 cm in length, is adapted to rocky limestone terrain, hiding in crevices, under rocks, and in the thin soil pockets on cliff faces, rocky outcrops, and canyon walls. The species is named for its high-pitched, insect-like chirping calls produced by males, particularly on humid nights following rainfall. Unlike many frogs, the Cliff Chirping Frog undergoes direct development: eggs are laid in moist rock crevices and develop directly into miniature froglets without a free-living aquatic larval stage, eliminating dependence on standing water for reproduction. Diet consists of small arthropods, insects, and other invertebrates encountered in rocky microhabitats. The species is cryptic and rarely seen but can be abundant in suitable habitat on the Edwards Plateau, an area of karst limestone geography. It is currently assessed as Least Concern by IUCN, with populations considered stable across its rocky limestone range.

Colombian Soft-furred Spiny-rat

<em>Diplomys caniceps</em>, the Colombian soft-furred spiny rat, is a rodent in the family Echimyidae found in Colombia. The genus <em>Diplomys</em> is characterised by a pelage that, despite the common name, is relatively soft compared to other spiny rats, with spine-like guard hairs interspersed among the fur. This species is assessed as Data Deficient by the IUCN, indicating that available information is insufficient to determine its conservation status reliably. Data Deficient assessments typically arise when a species occupies remote or poorly surveyed habitats, or when taxonomic uncertainties complicate population estimates. <em>Diplomys caniceps</em> is believed to inhabit tropical lowland and montane forests of Colombia, where it likely feeds on plant material including seeds, fruits, and fibrous vegetation. As a medium-sized terrestrial rodent, it probably serves as prey for a range of forest predators. The lack of ecological and distributional data underscores the need for targeted field surveys. Biological traits of this species remain poorly documented in the scientific literature.
