Common Starwort

<em>Stellaria graminea</em>, commonly known as the common starwort or lesser stitchwort, is a slender perennial herb in the family Caryophyllaceae, widely distributed across the temperate regions of Europe and Asia. This species typically inhabits grasslands, meadows, heathlands, woodland margins, roadsides, and hedgerow banks, favouring moderately acidic to neutral, nutrient-poor soils and tolerating a range of moisture conditions. Its geographic range extends from the British Isles and Scandinavia across continental Europe into Russia, Central Asia, and as far east as China and Japan, making it one of the more broadly distributed members of the genus. Classified as Least Concern on the IUCN Red List, <em>Stellaria graminea</em> remains common and stable across much of its extensive Eurasian range. The plant produces small white flowers with five deeply bifid petals, giving the appearance of ten petals, characteristic of the family Caryophyllaceae. Stems are typically weak and straggling, supported by surrounding vegetation, and reach lengths of approximately 15–60 cm. As a plant, dietary traits in the zoological sense are not applicable. Biological traits such as average individual lifespan, body weight, and precise dimensional measurements remain poorly documented, though the species is perennial and may persist at established sites for many years.

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.
