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.

cloaked bulrush

Habitat

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

Range

Found in Canada.

blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

cloaked bulrush

Cloaked bulrush refers to a wetland sedge species in the genus Scirpus or closely related genera in the family Cyperaceae, characterized by flowering spikelets partially enclosed or concealed by subtending bracts giving the inflorescence a 'cloaked' appearance. Bulrushes of this type are emergent aquatic plants found in freshwater marshes, fens, lake margins, and wet meadows across temperate regions of Europe, Asia, and North America. They produce robust, cylindrical or triangular stems rising from creeping rhizomes, with clusters of small, scale-covered spikelets that release wind-dispersed achenes. Scirpus and related genera play important ecological roles in wetland ecosystems, providing habitat and food for waterfowl, wading birds, and invertebrates, while stabilizing shorelines and filtering nutrients from agricultural runoff. The dense root systems of bulrushes trap sediments and contribute organic matter to wetland soils. Many wetland sedge species face pressure from drainage, water level manipulation, eutrophication, and invasive species competition, making conservation of naturally functioning wetland habitats critical for their persistence.
