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.

compact rustwort

<em>Marsupella condensata</em>, the compact rustwort, is a small leafy liverwort in the family Gymnomitriaceae found in Arctic and alpine habitats in Europe, with documented occurrences in Norway and Sweden. Liverworts in the genus Marsupella are characterised by their simple thalloid or leafy structure and specialisation for cold, wet, and exposed environments including snowflush communities, fellfields, and soliflucted soils at high elevation or high latitude. Compact rustwort typically grows in moist, acidic substrates near late-lying snow patches and on wet rock surfaces in montane tundra and alpine heath. These habitats are highly sensitive to climate change, with warming temperatures and reduced snowpack directly threatening snowflush plant communities across Scandinavia. The IUCN classifies <em>Marsupella condensata</em> as Least Concern, although its dependence on cold, moist microhabitats makes it potentially sensitive to long-term climate warming. The species contributes to biological soil crusts and serves as a substrate for invertebrates and microorganisms in fragile alpine ecosystems. Bryophytes like compact rustwort are often slow-growing and slow to recolonise following disturbance. Biological traits including growth rates, reproductive biology, and precise morphological measurements remain poorly documented, as is typical for many liverwort species outside specialist botanical surveys. Its conservation depends on the preservation of intact alpine and Arctic habitats across Scandinavia.
