Habitat & Geographic Range

백상아리

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate broadleaf and mixed forests, and temperate grasslands and steppes, among 9 distinct biome types spanning the Indomalayan and Neotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Chile, Norway, Portugal, and Taiwan. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Knotweed

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Asia (Taiwan), Europe (10 countries), and North America (Mexico, United States).

백상아리

지구상에서 가장 큰 포식성 어류인 백상아리는 전 세계 주요 대양의 시원한 연안 및 원해에 서식하며, 체장 6미터, 체중 2,000킬로그램까지 성장할 수 있습니다. 해양 포유류, 대형 어류, 바닷새를 주요 먹이로 하여 아래에서 기습 공격하는 최상위 포식자입니다. 무서운 명성에도 불구하고 인간에 대한 비도발적 공격은 극히 드뭅니다. 지느러미 채취, 혼획, 목적성 포획으로 개체수가 감소하고 있어 IUCN에서 취약(VU)으로 분류되며, 많은 지역에서 법적 보호를 받고 있습니다.

Common Knotweed

Common Knotweed (<em>Polygonum arenastrum</em>) is a prostrate annual herb in the family Polygonaceae, distributed across Asia, Europe, and North America. Its native range encompasses Taiwan in Asia, ten European countries, and Mexico and the United States in North America. The species typically colonizes highly disturbed, compacted substrates such as footpaths, roadsides, cultivated ground, and waste places, exhibiting a strong association with anthropogenic disturbance. Its wiry, branching stems and small, pale pink flowers form dense mats close to the ground, making it well adapted to trampled environments. The conservation status of this species has not been formally evaluated by the IUCN. As a cosmopolitan ruderal plant, it is broadly tolerant of environmental stress and contributes to ground cover in highly modified habitats throughout the temperate zone. Biological traits of this species remain poorly documented in the scientific literature.
