erva-de-são-joão

<em>Hypericum perforatum</em>, commonly known as common St. John's wort, is a flowering plant in the family Hypericaceae, order Malpighiales. It enjoys a cosmopolitan distribution, naturally occurring across Europe, western Asia, and North Africa, and has become widely naturalized in North and South America, Australia, and parts of Asia. The species typically inhabits roadsides, meadows, disturbed ground, and open woodland edges, preferring well-drained soils and full sun to partial shade. Its bright yellow flowers, distinguished by black glandular dots along the margins, bloom from late spring through summer. <em>Hypericum perforatum</em> has long been used in herbal medicine, particularly for its antidepressant properties attributed to the compound hypericin. The plant is also known to cause photosensitivity in livestock when ingested in large quantities. Biological traits including precise lifespan, reproductive output rates, and specific dietary associations remain poorly documented at the species level. Its conservation status is Least Concern, and it is considered a common weed in many regions, indicating a stable and widespread global population.

Leao

O maior felino selvagem da África, o leão pode atingir até 250 kg e é o único felídeo social, vivendo em grupos nas savanas e pastagens da África Subsaariana. Os machos se distinguem por suas icônicas juba. Como predadores de topo, regulam as populações de herbívoros e mantêm o equilíbrio do ecossistema. Classificado como Vulnerável devido à perda de habitat e ao conflito entre humanos e vida selvagem.
