cluster fig

Ficus racemosa, commonly called the cluster fig or red river fig, is a large deciduous to semi-evergreen tree in the family Moraceae with a native range spanning tropical Asia, including the Indian subcontinent, Southeast Asia, and extending to northern Australia. Despite records suggesting Brazil and Taiwan, the species is most reliably native to South and Southeast Asia. The cluster fig is famous for its remarkable reproductive strategy: fruits grow directly from the trunk and major branches in dense clusters, a habit known as cauliflory. These figs are critical food resources for a wide array of frugivores including bats, birds, monkeys, and civets, making F. racemosa a keystone species in riparian and moist deciduous forests. Trees can reach 15–30 meters in height and develop buttressed bases when growing along riverbanks and in seasonally flooded areas. Like all figs, Ficus racemosa shares an obligate mutualism with its specific fig wasp pollinator, without which reproduction is impossible. Fruits have long been used in traditional medicine across South Asia to treat various ailments. The tree is classified as Least Concern by the IUCN, reflecting its wide distribution and adaptability, though local populations may face pressure from deforestation and river channelization in its native range.

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.
