Habitat & Geographic Range

Elefante de Sabana

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 5 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Kenya. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Boulder Lichen

Habitat

Native to Europe and North America and South America, inhabiting ecosystems characteristic of the region.

Range

Widely distributed across Europe (4 countries), North America (United States), and South America (Colombia). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Elefante de Sabana

El elefante africano, el animal terrestre más grande de la Tierra, puede alcanzar 7.000 kg y habita sabanas, bosques y humedales del África subsahariana. Con estructuras sociales complejas lideradas por matriarcas, se comunica mediante infrasonidos, rugidos y contacto físico. Como ingeniero del ecosistema, modela su hábitat arrancando árboles, excavando aguadas y dispersando semillas. Está catalogado como Vulnerable, con poblaciones en declive por la caza furtiva de marfil y la pérdida de hábitat.

Common Boulder Lichen

The common boulder lichen (<em>Porpidia macrocarpa</em>) is a crustose lichen species with a wide distribution across Europe and the Americas, recorded in Colombia, Denmark, Norway, Portugal, Sweden, and the United States. This species typically inhabits siliceous rock surfaces in a variety of exposed terrestrial environments across both North and South America and Europe. The common boulder lichen is classified as Near Threatened on the IUCN Red List, suggesting that its populations face potential pressures and require monitoring. As a slow-growing crustose lichen, it often colonizes hard rock substrates including granite and quartzite, forming a close symbiotic relationship between its fungal and algal components. It plays an important role in the early stages of soil formation through the gradual weathering of rock surfaces. Biological traits of this species remain poorly documented in the scientific literature.
