Ciliolate Aster

Ciliolate aster (Symphyotrichum ciliolatum) is a perennial wildflower in the family Asteraceae, native to central and northern North America, from the Great Plains east through the Great Lakes region and into the northeastern United States and southern Canada. It grows in open woodland, prairie margins, roadsides, and disturbed ground, preferring well-drained to moderately moist soils with full sun. The plant produces upright stems 40–100 centimeters tall bearing alternate, clasping leaves with slightly fringed (ciliolate) margins, and branched clusters of lavender to blue-violet daisy-like flower heads with yellow disc florets. Blooming occurs in late summer and autumn, providing important nectar for migrating monarch butterflies and native bees. Symphyotrichum ciliolatum is classified as Not Evaluated by the IUCN and is common across its native range. The genus Symphyotrichum was split from the broadly defined Aster following molecular phylogenetic work that demonstrated the non-monophyly of the traditional genus. Ciliolate aster is one of many native North American aster species with a wide distribution, though it is absent from Europe despite some database records listing Norway as its country—an artifact of data entry errors in global species databases. Conservation of native prairie and open woodland habitats benefits this species alongside its many pollinators.

Comoro Rousette

<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
