Habitat & Geographic Range
cloud-borne aloe
Typically found in grasslands, wetlands, forests, and cultivated landscapes.
Common Seal
Typically found in diverse ecosystems where prey species are available.
Found across Europe (7 countries) and North America (United States). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.
cloud-borne aloe
Cloud-borne aloe refers to an Aloe species native to high-elevation montane habitats in eastern or southern Africa, adapted to the misty, cloud-shrouded conditions of afromontane forest margins and rocky highland slopes. Aloe species at altitude typically experience different rainfall patterns, lower temperatures, and higher UV radiation than their lowland relatives, driving adaptations in leaf chemistry, water storage capacity, and root architecture. High-altitude aloes often produce rosettes with thick, succulent leaves containing gel-rich mesophyll tissue for water storage, adapted to both the seasonal dry periods and the fog drip typical of cloud forest margins. Many montane African aloes are important nectar sources for sunbirds and other highland bird species that serve as their primary pollinators. Several cloud forest aloe species face threats from habitat loss as montane forests and grasslands are converted to agriculture, combined with overcollection for the traditional medicine trade and for horticultural markets, contributing to conservation assessments of Vulnerable or Endangered for several highland Aloe taxa.
Common Seal
分布最广的鳍足类动物港海豹(Phoca vitulina)栖居于北大西洋和北太平洋温带及亚北极沿海水域。成体体重可达130千克,在海中捕食鱼类、鱿鱼和甲壳动物,并在沙滩或礁岩上休息,两者时间大致相当。大而富有表情的眼睛适应于弱光下的水下视觉。港海豹是虎鲸、鲨鱼和北极熊的重要食物来源。
