Common Sensitive-Plant

<em>Mimosa pudica</em>, the common sensitive plant, is a pantropical annual or perennial herb in the family Fabaceae, order Fabales, native to South and Central America but now naturalized across tropical Africa, Asia, Europe, North America, Oceania, and South America. This species is best known for its rapid thigmonastic leaf movements — leaflets and petioles fold inward and droop within seconds of being touched or disturbed, a response thought to deter herbivores and reduce water loss. <em>Mimosa pudica</em> typically grows as a sprawling, prickly herb in disturbed habitats including roadsides, pastures, and degraded lands, and produces small pink to purple spherical flower heads. The seeds are dispersed via various vectors and germinate readily, contributing to its success as an invasive species in many regions outside its native range. The species is listed as Least Concern by the IUCN, reflecting its wide distribution and high adaptability. Biological traits for this species remain poorly documented in the scientific literature in terms of standardized averages for lifespan, plant height, and weight, though its growth habit and ecological behavior as a pioneer and potential invasive are well characterized.

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.
