Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Oak Pigmy

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Cheetah

猎豹是地球上奔跑最快的陆地动物，在非洲和伊朗草原上短距离冲刺速度可达112千米/小时。体型纤细，胸深腿长，具有标志性的黑色泪纹。与其他大型猫科动物不同，猎豹以吱鸣声和咕噜声交流。由于栖息地碎片化和与更大型捕食者的竞争，猎豹被列为易危，野外仅剩约7,000只。

Common Oak Pigmy

<em>Stigmella roborella</em>, the common oak pigmy, is a minute leaf-mining moth in the family Nepticulidae, one of the smallest families of moths. The larvae of <em>Stigmella roborella</em> 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. <em>Stigmella roborella</em> 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.
