Colchian Hazel

<em>Corylus colchica</em>, the Colchian Hazel, is a woody plant in the family Betulaceae. This species is classified as Vulnerable on the IUCN Red List, indicating a high risk of extinction under current conditions. The epithet "colchica" refers to Colchis, an ancient region corresponding roughly to present-day western Georgia in the Caucasus, suggesting a geographic origin in that region. The species is associated with diverse terrestrial habitats ranging from tropical to temperate zones, reflecting the ecological breadth often seen in the genus <em>Corylus</em>. Hazels in this genus typically produce edible nuts and catkins, and often form thickets or understory growth in mixed forests. No specific countries are listed in the available records for <em>Corylus colchica</em>, limiting precise range documentation. Diet information, population estimates, and biological measurements including length, weight, and lifespan are not documented in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its Vulnerable status highlights the need for targeted conservation assessments and habitat protection within its native range.

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.
