Habitat & Geographic Range

African elephant

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.

Coalman

Habitat

Typically found in forest floors, decomposing wood, and soil ecosystems.

Range

Found across Europe (5 countries) and North America (United States).

African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Coalman

Tricholoma portentosum, commonly called the coalman or soapy knight, is a large, prized edible mushroom in the family Tricholomataceae forming ectomycorrhizal associations with conifers, especially pines and spruces, across temperate forests of Europe and North America. The fruiting body features a grey to blackish fibrous cap 6–12 centimeters in diameter with a wavy, often undulating margin, white to pale yellow gills with a slightly soapy odour, and a white stem with grey streaks. It typically fruits in autumn in pine forests and mixed coniferous-deciduous woodland, where its underground mycorrhizal network supports tree health and nutrient uptake. Tricholoma portentosum is considered a fine edible species in several European countries, particularly in Spain, Poland, and Italy, where it is collected commercially and sold in markets. The genus Tricholoma contains numerous similar grey or silvery species, making field identification challenging and requiring careful attention to habitat, odour, and microscopic features. The species is classified as Data Deficient by the IUCN, reflecting insufficient baseline population data to determine whether it is declining. Broader declines in fruiting body abundance of ectomycorrhizal fungi across Europe have been documented through long-term monitoring, attributed primarily to atmospheric nitrogen deposition altering forest nitrogen dynamics.
