Common Spindle

<em>Euonymus europaeus</em>, commonly known as the common spindle, is a deciduous shrub or small tree in the family Celastraceae, native to Europe and western Asia. This species typically inhabits woodland edges, hedgerows, scrubland, calcareous grassland margins, and riverbanks, preferring well-drained soils on chalk and limestone but tolerating a variety of substrates. Its geographic range extends across most of Europe from the British Isles and Scandinavia south to the Mediterranean, and eastward through the Caucasus into western Asia. Classified as Least Concern on the IUCN Red List, <em>Euonymus europaeus</em> maintains stable populations throughout its native range. The species is particularly notable for its striking autumn display of bright pink to crimson four-lobed capsular fruits that split to reveal orange-coated seeds, providing an important food source for robins, blackcaps, and other birds. The seeds are toxic to humans and many mammals. The plant typically grows to 2–6 metres in height and produces small inconspicuous greenish-white flowers in spring. Biological traits such as average individual lifespan, precise body dimensions, and specific weight measurements remain poorly documented at the population level for this shrub. The hard, fine-grained wood has historically been used for making spindles and skewers, giving rise to the common name.

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.
