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.

Cluster Fescue

Habitat

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

Range

Found in United States.

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.

Cluster Fescue

Cluster fescue, known scientifically as Festuca paradoxa, is a perennial bunchgrass in the family Poaceae that holds the tragic distinction of being Extinct. Endemic to the central and eastern United States, this grass once inhabited moist, shaded woodland edges, floodplain forests, and riverbank communities where it formed discrete clumps characteristic of caespitose fescues. Festuca paradoxa was a slender, cool-season grass reaching approximately 60–120 centimeters in height, with flat or loosely rolled leaf blades and an open panicle inflorescence. It was associated with rich bottomland soils where periodic flooding maintained the open canopy conditions it required. The species declined catastrophically due to the widespread destruction of floodplain woodlands across its range through agricultural conversion, wetland drainage, and urban development over the nineteenth and twentieth centuries. Invasive species competition and altered hydrological regimes further compressed suitable habitat. The genus Festuca contains hundreds of species distributed globally in temperate and montane regions, but F. paradoxa occupied a narrow ecological niche that proved impossible to sustain amid large-scale landscape transformation. Its extinction represents a permanent loss from North American grassland diversity, and no living populations are known to persist anywhere in its former range.
