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.

Comoro Blue-Pigeon

<em>Alectroenas sganzini</em>, the Comoro blue pigeon, is a medium-sized frugivorous pigeon in the family Columbidae, endemic to the Comoro Islands archipelago in the western Indian Ocean, with occasional records from Aldabra Atoll in the Seychelles. The species inhabits dense evergreen humid forest, forest edges, and heavily wooded areas, typically from sea level to higher elevations on the main islands. Like other members of the genus <em>Alectroenas</em>, it displays striking plumage featuring a bright blue-grey body, a bare red facial patch around the eye, and a short rounded tail. Biological traits such as precise average lifespan, body length, and weight remain poorly documented in consolidated scientific literature, though it is a medium-sized pigeon typical of its genus. The Comoro blue pigeon feeds primarily on fruits, figs, and other forest products, contributing to seed dispersal in native forests. Threats include ongoing habitat loss through forest clearance for agriculture and charcoal production, along with hunting pressure. <em>Alectroenas sganzini</em> is assessed as Near Threatened by the IUCN, reflecting population declines driven by deforestation and exploitation across its restricted island range in the Comoros.
