Habitat & Geographic Range

Ballena azul

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.

carrizo común

Habitat

Found across multiple habitat types including flooded grasslands and savannas, deserts and xeric shrublands, and temperate broadleaf and mixed forests, among 6 distinct biome types spanning the Afrotropic and Palearctic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (4 countries), Asia (Iran, Pakistan, Taiwan), Europe (7 countries), North America (Canada, United States), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).

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.

carrizo común

<em>Phragmites australis</em>, the common reed, is one of the most widely distributed vascular plants on Earth, placed in the family Poaceae, order Poales. Its range encompasses all inhabited continents, including Africa, Asia, Europe, North America, Oceania, and South America, typically colonizing freshwater margins, brackish marshes, lake shores, riverbanks, and coastal wetlands. The species is assessed as Least Concern by the IUCN, with globally abundant populations, though some regional variants are subject to conservation concern. Common reed typically forms dense monoculture stands reaching heights of two to six meters, providing critical habitat structure for a wide range of wetland birds, invertebrates, and small mammals. It is a rhizomatous perennial grass, spreading vegetatively through extensive underground root systems as well as by wind-dispersed seeds. As an autotroph, <em>Phragmites australis</em> obtains energy through photosynthesis and plays a major role in nutrient cycling and carbon sequestration within wetland ecosystems. The species has significant economic value in thatching, basketry, and constructed wetland wastewater treatment systems. In North America, an introduced European genotype has become invasive, displacing native plant communities. Biological traits vary considerably across its global range.
