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 Spindle

Habitat

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

Range

Widely distributed across Europe (7 countries), North America (Canada, United States), and Oceania and the Pacific (Australia, New Zealand).

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Common Spindle

<em>Euonymus europaeus</em>, commonly known as the common spindle, is a deciduous shrub or small tree in the family Celastraceae, native to Europe and western Asia. This species typically inhabits woodland edges, hedgerows, scrubland, calcareous grassland margins, and riverbanks, preferring well-drained soils on chalk and limestone but tolerating a variety of substrates. Its geographic range extends across most of Europe from the British Isles and Scandinavia south to the Mediterranean, and eastward through the Caucasus into western Asia. Classified as Least Concern on the IUCN Red List, <em>Euonymus europaeus</em> maintains stable populations throughout its native range. The species is particularly notable for its striking autumn display of bright pink to crimson four-lobed capsular fruits that split to reveal orange-coated seeds, providing an important food source for robins, blackcaps, and other birds. The seeds are toxic to humans and many mammals. The plant typically grows to 2–6 metres in height and produces small inconspicuous greenish-white flowers in spring. Biological traits such as average individual lifespan, precise body dimensions, and specific weight measurements remain poorly documented at the population level for this shrub. The hard, fine-grained wood has historically been used for making spindles and skewers, giving rise to the common name.
