Climbing Cactus

Climbing Cactus is a common name applied to several species in the cactus family Cactaceae that have adopted a climbing or scrambling growth habit, clinging to trees, rock faces, and other supports using aerial roots or woody stems, rather than the upright or columnar forms typical of desert-dwelling cacti. Notable climbing cacti include species of Selenicereus, Hylocereus, and Epiphyllum, found in tropical and subtropical forests of Central and South America and the Caribbean. These species are often epiphytic or hemi-epiphytic, growing from forest floor to canopy by scrambling up tree trunks or clambering over rocks in humid forest environments. Many climbing cacti produce large, spectacular nocturnal flowers pollinated by bats and hawk moths, which are attracted to fragrant, white blooms opening for a single night. The dragon fruit (Hylocereus undatus) is the commercially most important climbing cactus, cultivated globally for its brightly colored, edible pitayas. Some climbing cactus species have very restricted natural ranges in tropical dry forests and coastal scrub and are threatened by habitat loss. Others have become invasive in parts of Africa, Asia, and the Pacific where they were introduced as ornamentals or for their fruit.

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.
