Tlaconete regordete

The Chunky False Brook Salamander (Aquiloeurycea cephalica) is a Least Concern plethodontid salamander endemic to Mexico, found in cloud forest and humid montane habitats in the Sierra Madre Oriental and related mountain ranges. The genus Aquiloeurycea is a recently erected Mexican endemic genus segregated from the broader genus Pseudoeurycea, comprising several small, robustly built (hence 'chunky') salamanders associated with high-elevation forests. Like all plethodontids, A. cephalica is a lungless salamander that breathes entirely through its moist, vascularized skin and the lining of its mouth. It is a direct developer, skipping the aquatic larval stage entirely and laying eggs in terrestrial microhabitats such as rotting logs, leaf litter, and soil. A. cephalica inhabits cool, humid forests of pine-oak and cloud forest zones in northern Mexico, where it forages for small invertebrates in the leaf litter and soil. The IUCN assesses it as Least Concern due to its reasonably wide distribution within its montane range. Deforestation, cattle grazing, and the conversion of cloud forest to agriculture represent ongoing threats to populations throughout its range.

Comadreja Colombiana

<em>Mustela felipei</em>, the Colombian weasel, is one of the rarest and least-known mustelids in the world, endemic to the Andes of Colombia. This species is assessed as Vulnerable by the IUCN, reflecting genuine conservation concern arising from its extremely restricted range and the continued degradation of Andean cloud forest and montane stream habitats upon which it depends. <em>Mustela felipei</em> is associated with rocky stream margins and humid upland forests, where it is believed to hunt fish, invertebrates, and small vertebrates in a manner consistent with other semi-aquatic weasels. The species was described scientifically only in 1978, and very few individuals have been observed in the wild, meaning that fundamental aspects of its ecology, behaviour, and reproductive biology remain unknown. Its small body size and cryptic habits make field observation exceptionally challenging. The primary threats to this species include deforestation, water pollution, and stream alteration within its narrow elevational range in the Colombian Andes. Biological traits of this species remain poorly documented in the scientific literature.
