Circumpolar sedge

The Circumpolar sedge (Carex adelostoma) is a species in the genus Carex. It is currently classified as Vulnerable on the IUCN Red List. Inhabits boreal forests and taiga within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Common Big-eared Bat

The common big-eared bat (<em>Micronycteris microtis</em>) is a small insectivorous bat belonging to the family Phyllostomidae, native to tropical and subtropical regions of South America. Its range includes Colombia and Venezuela, where it typically inhabits diverse terrestrial and aquatic environments including forests and riparian zones. It is classified as Least Concern on the IUCN Red List, indicating a relatively stable population. As its common name suggests, <em>Micronycteris microtis</em> is distinguished by notably large ears relative to its body size, which enhance its echolocation capabilities for detecting prey and navigating complex forest environments. The species is often associated with lowland and foothill forests, roosting in caves, hollow trees, and dense vegetation. It typically feeds on insects and may also consume small vertebrates or fruit on occasion. Biological traits of this species remain poorly documented in the scientific literature.
