Climbing Euonymus

Climbing Euonymus, Euonymus fortunei, is a woody, evergreen vine or groundcover in the family Celastraceae native to China, Japan, Korea, and other parts of eastern Asia. It climbs walls, trees, and rocky surfaces using small adventitious roots along its stems, similar to ivy (Hedera helix). The leaves are small, oval to elliptic, and glossy dark green, often variegated in cultivated forms that are popular in horticulture. Climbing Euonymus produces inconspicuous greenish-white flowers in summer, followed by pinkish-orange capsular fruits that split to reveal bright orange-red seeds attractive to birds. The species is widely cultivated as an ornamental groundcover and climbing plant in temperate gardens worldwide and has become an invasive species in many parts of North America, Australia, and parts of Europe, where it escapes cultivation and spreads aggressively through forests and natural habitats. In eastern North America, Climbing Euonymus invades mature deciduous forests, climbing trees and smothering native vegetation. In its native Asian range, the species grows in mixed forests, forest margins, and rocky slopes and is not considered threatened. Control of invasive populations typically requires physical removal and herbicide treatment.

Comoro Flying Fox

<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.
