Coast Sedge

Coast sedge (Carex exilis) is a slender, tufted perennial sedge in the family Cyperaceae, native to boggy and peaty habitats in northeastern North America, from Newfoundland and Labrador south through New England and the Great Lakes region to the mid-Atlantic states. It grows in sphagnum bogs, fens, moist sandy peats, and the margins of coastal plain ponds—habitats characterised by low nutrient availability, high moisture, and acidic soils. The species produces narrow, grass-like leaves and small, inconspicuous flower spikes typical of the vast Carex genus, which is one of the largest and most ecologically diverse plant genera on Earth. Coast sedge is assessed as Least Concern by the IUCN, reflecting its distribution across a range of protected coastal plain and boreal wetland habitats in northeastern North America. The coastal plain ponds it inhabits are considered globally rare ecosystems of high botanical interest. Like many sedges, coast sedge provides important habitat structure for invertebrates, breeding birds such as sedge wrens, and small mammals in wetland communities.

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.
