Ascending Grapefern

Ascending grapefern (Botrychium ascendens) is a species in the genus Botrychium. Typically found in moist, shaded forest floors and tropical canopies.

<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.
