Épervière vulgaire

The common hawkweed, <em>Hieracium lachenalii</em>, is a flowering plant belonging to the family Asteraceae, the daisy family. Its known range includes the United States, where it may be found as a non-native introduction, as many hawkweeds have naturalized broadly beyond their native European ranges. As a member of the genus Hieracium, <em>Hieracium lachenalii</em> is a perennial herb typically recognized by its dandelion-like yellow flower heads and rosette of basal leaves. Hawkweeds are known for their complex taxonomy and tendency toward apomixis, the production of seeds without fertilization, which has led to the description of numerous microspecies within the genus. No dietary information has been provided for this species. Biological traits of this species remain poorly documented in the scientific literature.

petite roussette des Comores

<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.
