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.

ours blanc

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
