Common Fat-tailed Mouse Opossum

The Common Fat-tailed Mouse Opossum (<em>Thylamys pusillus</em>) is a small marsupial belonging to the genus Thylamys within the family Didelphidae. Like other members of its genus, this species typically stores fat in its tail, which becomes swollen during periods of food abundance and is metabolised during leaner times, a physiological adaptation that provides energy reserves. <em>Thylamys pusillus</em> is generally found in diverse terrestrial and aquatic ecosystems, often in dry woodlands, scrublands, and grassland habitats of South America. The species is assessed as Least Concern on the IUCN Red List, indicating it is not currently considered at risk of extinction. Detailed geographic range data are not available in the current record, but members of this genus are typically distributed across parts of Argentina, Bolivia, Paraguay, and Uruguay. Biological traits including average lifespan, body dimensions, and specific dietary composition remain poorly documented in the scientific literature, though Thylamys species are generally considered omnivorous, often consuming insects, small vertebrates, and plant material.

Common Forest Grape

<em>Rhoicissus tridentata</em> is a woody climbing plant in the family Vitaceae, order Vitales, commonly known as the common forest grape or bushman's grape. The species is classified as Least Concern on the IUCN Red List. <em>Rhoicissus tridentata</em> is native to sub-Saharan Africa, where it typically grows in forest margins, thickets, rocky outcrops, and riverine woodlands. It climbs by means of tendrils, often scrambling over shrubs and into tree canopies. The plant produces small, dark purple to black berries that are edible and have been used as a food source by indigenous communities across its range. Leaves are trifoliate — composed of three leaflets — a feature reflected in the species epithet "tridentata." The roots of this species have been used in traditional medicine in southern Africa for a variety of ailments. Biological traits of this species remain poorly documented in the scientific literature.
