Habitat & Geographic Range

blue whale

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 (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

common rock-rose

Habitat

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

Range

Found across Europe (6 countries). Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

지구에서 살았던 것으로 알려진 가장 큰 동물로, 대왕고래(Balaenoptera musculus)는 33미터, 200톤에 달할 수 있으며, 심장만도 소형 자동차 무게와 비슷합니다. 모든 대양에 서식하며, 극지방 먹이 지역과 열대 번식 지역 사이를 이동합니다. 하루 최대 4톤의 크릴새우를 섭취하는 여과 섭식자입니다. 20세기 포경으로 인한 거의 멸종 이후 전 세계 개체수가 10,000~25,000마리로 추정되는 멸종위기 종입니다.

common rock-rose

<em>Helianthemum nummularium</em>, the common rock rose, is a low-growing subshrub in the family Cistaceae, order Malvales. It is assessed as Near Threatened on the IUCN Red List and is distributed across Europe, with populations documented in Belgium, Czech Republic, Germany, Norway, Sweden, and the United Kingdom. Common rock rose typically grows in calcareous grasslands, rocky outcrops, chalk and limestone downlands, and dry heathland habitats with well-drained, nutrient-poor soils. It is a characteristic species of traditionally managed grasslands and is considered a key plant in European chalk grassland communities. The plant produces small but vivid yellow five-petaled flowers from late spring to midsummer, attracting a range of pollinating insects. <em>Helianthemum nummularium</em> is a host plant for the caterpillars of several specialist butterfly species, including the brown argus. Its Near Threatened status reflects the significant loss of calcareous grassland habitat across Europe due to agricultural intensification, scrub encroachment, and land use change. As a plant, biological traits such as lifespan and diet are measured differently than in animals; the species is a perennial subshrub with vegetative spread and seed reproduction. Conservation grazing management is critical for maintaining suitable habitat for this species.
