Distributed across Cameroon, Congo (Republic), Equatorial Guinea, and Gabon. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Oak Pigmy

Stigmella roborella, the common oak pigmy, is a minute leaf-mining moth in the family Nepticulidae, one of the smallest families of moths. The larvae of Stigmella roborella mine the leaves of oak trees (Quercus species), creating sinuous, narrow galleries within the leaf parenchyma that are characteristic of the genus. This species typically inhabits deciduous woodland, forest margins, parks, and hedgerows throughout temperate Europe wherever suitable oak host trees occur. Its geographic range includes Belgium, Denmark, Norway, and Sweden, reflecting a broad temperate European distribution. The species is currently assessed as Least Concern by the IUCN. Biological traits such as lifespan, body size, and diet remain poorly documented at a formal population level for this species, though larval leaf-mining on Quercus is well established in entomological literature. Adults are extremely small with narrow, metallic-patterned wings. Stigmella roborella contributes to the rich invertebrate biodiversity associated with European oak ecosystems and serves as an indicator of the ecological complexity supported by oak-dominated woodland habitats.

gorilla

世界最大の霊長類であるニシゴリラは体重が最大180kgに達し、赤道アフリカの熱帯・亜熱帯の森林に生息する。主に草食性で、群れを守り社会的な対立を仲裁するシルバーバック雄が率いる家族集団を形成する。森林破壊、食肉目的の密猟、エボラウイルス感染症の流行により脅威にさらされており、近絶滅種（CR）に指定されている。
