pin de hoop

<em>Araucaria cunninghamii</em>, the colonial pine or hoop pine, is a large coniferous tree in the ancient family Araucariaceae, native to Australia and also cultivated or naturalised in India, Libya, and South Africa. This species inhabits temperate and boreal forests at higher elevations, where it often forms a prominent emergent layer in subtropical and tropical rainforest communities in Queensland and New Guinea. Hoop pine is one of Australia's most commercially important softwood timber species, valued for its straight grain, durability, and workability. Trees can grow to considerable heights, with tall trunks characterised by horizontally spreading branch whorls that give the species a distinctive silhouette. <em>Araucaria cunninghamii</em> is assessed as Least Concern by the IUCN. The genus <em>Araucaria</em> has ancient origins, with fossil records extending to the Jurassic period, making it a living relic of Gondwanan flora. Seeds of hoop pine are consumed by birds and other fauna in its native range, contributing to limited seed dispersal. Biological traits of this species remain poorly documented in the scientific literature.

Roussette de Livingstone

<em>Pteropus livingstonii</em>, the Comoro flying fox or Livingstone's fruit bat, is a large fruit bat in the family Pteropodidae, endemic to the Comoro Islands in the western Indian Ocean, where it is restricted to Anjouan and Mohéli. It is one of the largest bats in the world, with a wingspan that can exceed one meter and a body weight reportedly ranging between 400–700 g. The species roosts colonially in tall native forest trees, particularly in humid upland forest fragments, and feeds on a variety of native fruits, nectar, and pollen, playing a critical role as a seed disperser and pollinator in Comoran forest ecosystems. Precise average lifespan data in the wild remain poorly documented, though captive individuals have lived over 20 years. <em>Pteropus livingstonii</em> is assessed as Critically Endangered by the IUCN, making it one of the most threatened bat species in the world. Primary threats include extensive deforestation driven by agricultural expansion and charcoal production, which has severely reduced suitable roosting and foraging habitat, along with historic hunting. Conservation efforts include habitat protection, community education programs, and captive breeding initiatives at several European zoos coordinated through an international species survival program.
