Common Star-apple

<em>Diospyros dichrophylla</em>, commonly known as the common star apple or bladder nut, is a small deciduous tree or shrub in the family Ebenaceae, native to southeastern Africa. This species typically inhabits riverine forests, bushveld margins, rocky hillsides, and scrubby thickets in subtropical and tropical woodland regions. It is distributed across southern and eastern Africa, with populations recorded in South Africa (particularly KwaZulu-Natal and Limpopo), Eswatini, Mozambique, and Zimbabwe. Classified as Least Concern on the IUCN Red List, <em>Diospyros dichrophylla</em> remains relatively widespread within suitable habitats across its range. The species produces small edible fruits that ripen to yellow or orange and are eaten by wildlife including birds and small mammals. The flowers are white and fragrant, and the plant is sometimes cultivated as an ornamental or for its edible fruit. Biological traits such as average lifespan, body dimensions, and dietary specifics remain poorly documented in the scientific literature for this plant species. The common name "star apple" in this context refers to the star-like pattern visible when the fruit is cut in cross-section. The species is ecologically important as a food and shelter resource for local fauna in its southeastern African range.

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.
