fougère mâle

<em>Dryopteris filix-mas</em>, the common male fern, is a robust, semi-evergreen fern in the family Dryopteridaceae, widely distributed across Europe, North America, Oceania, and South America. It is classified as Least Concern on the IUCN Red List. This species typically grows in moist, shaded forest floors, hedgebanks, rocky slopes, and stream margins, preferring acidic to neutral soils in temperate environments. The common male fern produces large, pinnate fronds that can reach over one metre in length, arising from a central crown of scaly rhizomes. It is one of the most familiar ferns of the Northern Hemisphere and has been used medicinally for centuries, with extracts historically employed as an anthelmintic to treat tapeworm infections. The species reproduces via spores produced in kidney-shaped sori arranged in rows on the undersides of fertile fronds. Common male fern plays an important role in forest ecosystems, providing shelter and habitat structure for invertebrates and small vertebrates across its broad temperate range.

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.
