Habitat & Geographic Range

Baleia jubarte

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

Common Spike-Rush

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Widely distributed across Europe (6 countries), North America (Canada, United States), and South America (Chile).

Baleia jubarte

Entre as baleias grandes mais acrobáticas, as baleias-jubarte são famosas por seus cantos complexos e evocativos entoados pelos machos durante a temporada reprodutiva, podendo durar horas e evoluir ao longo do tempo. Atingindo 16 metros e 30 toneladas, realizam as migrações mais longas de qualquer mamífero. Encontradas em todos os oceanos, alimentam-se de krill e peixes pequenos usando a técnica cooperativa de rede de bolhas.

Common Spike-Rush

<em>Eleocharis palustris</em>, commonly known as the common spike-rush, is a perennial wetland sedge in the family Cyperaceae, broadly distributed across the temperate and boreal regions of the Northern Hemisphere. This species typically inhabits shallow freshwater marshes, pond margins, riverbanks, wet meadows, ditches, and other seasonally or permanently flooded habitats, tolerating a range of water depths and soil conditions. Its geographic range spans Europe, Asia, and North America, extending from subarctic regions southward into subtropical zones. Classified as Least Concern on the IUCN Red List, <em>Eleocharis palustris</em> is among the most ecologically widespread wetland plant species globally. It forms dense stands via rhizomatous growth, providing important cover, nesting sites, and food resources for waterfowl and invertebrates. The plant produces leafless green culms up to approximately 60 cm tall, bearing a single terminal spikelet. As a plant, dietary traits in the animal sense are not applicable. Biological traits such as average individual lifespan, body dimensions in the zoological sense, and body weight remain poorly documented, as these metrics are not typically applied to non-vascular measurements in this genus. The species plays a critical ecological role in stabilising wetland sediments and maintaining water quality.
