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 Oak Sedge

Habitat

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

Range

Distributed across Canada, Norway, and United States.

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 Oak Sedge

<em>Carex pensylvanica</em> is a low-growing perennial sedge in the family Cyperaceae, native to eastern North America, including Canada and the United States, with isolated records from Norway. It typically inhabits dry to mesic woodlands, grasslands, and forest edges, forming dense clonal colonies through rhizomatous spread. The species is well adapted to shaded environments and is often found beneath oak canopies, which gives it its common name. Its habitat associations span grasslands, wetlands, open forests, and disturbed or cultivated areas. The plant produces slender, grass-like leaves and small inconspicuous flower spikes characteristic of the genus Carex. It tolerates a range of soil conditions, from sandy to moderately fertile substrates. Conservation status has not been formally evaluated by the IUCN, and the species is considered broadly secure across its native range. Biological traits such as average lifespan, body measurements, and dietary preferences remain poorly documented in standardized databases for this plant species. It plays an ecological role as ground cover and erosion stabilizer in woodland understories, and is increasingly used in native plant landscaping and ecological restoration projects.
