Common Male Fern

<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.

pinguim-imperador

O maior pinguim do mundo, os pinguins-imperadores medem até 1,2 metro de altura e pesam 45 kg, habitando o continente antártico em algumas das condições mais extremas da Terra. Reproduzem-se no meio do inverno, na escuridão, a temperaturas abaixo de -60°C, com os machos incubando ovos únicos sobre os pés sob uma bolsa de criação por 65 dias enquanto as fêmeas estão no mar. Seu comportamento de aglomeração — onde os indivíduos revezam-se pelo centro quente de grupos de milhares — é uma obra-prima de sobrevivência cooperativa.
