Habitat & Geographic Range

大翅鯨

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Freckle Pelt Lichen

Habitat

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

Range

Distributed across Denmark, Norway, Sweden, and United States.

大翅鯨

座头鲸是大型鲸类中最具杂技表演性的物种之一，以繁殖季节雄性演唱的复杂而神秘的歌声著称，歌声有时持续数小时并随时间演变。体长可达16米，体重30吨，进行着哺乳动物中最长距离的洄游。分布于所有大洋，通过协作泡泡网捕食磷虾和小鱼。种群数量已从历史捕鲸后大体恢复。

Common Freckle Pelt Lichen

<em>Peltigera aphthosa</em> is a foliose lichen in the family Peltigeraceae, order Peltigerales, commonly known as common freckle pelt or speckled felt lichen. This species holds the conservation status of Extinct on the IUCN Red List, representing a serious loss of biodiversity. <em>Peltigera aphthosa</em> has been recorded in Denmark, Norway, Sweden, and the United States. Historically, this lichen grew in cool, humid environments including boreal and montane forests, typically on mossy ground, rocks, and tree bases in old-growth habitats. Like other members of the genus Peltigera, <em>Peltigera aphthosa</em> is a tripartite lichen containing a cyanobacterial photobiont (providing nitrogen fixation) in addition to the primary green algal photobiont and fungal mycobiont, making it an ecologically significant contributor to nutrient cycling. Its large, lobed thallus was characterized by distinctive dark cephalodia — wart-like structures housing the nitrogen-fixing cyanobacteria. The extinction of this species underscores the vulnerability of lichens to habitat degradation, air pollution, and climate change. Biological traits of this species remain poorly documented in the scientific literature.
