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.

Common dogmustard

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Asia (Japan), Europe (24 countries), and North America (Canada, Mexico, 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.

Common dogmustard

<em>Erucastrum gallicum</em>, the common dogmustard, is an annual or biennial herb in the family Brassicaceae. This species has a broad distribution across Asia, Europe, and North America, with records from Japan, twenty-four European countries, Canada, Mexico, and the United States. It typically inhabits disturbed terrestrial environments such as roadsides, waste ground, agricultural margins, and rocky or sandy soils. Common dogmustard is characterized by its deeply lobed leaves, slender branching stems, and small pale yellow four-petaled flowers arranged in elongated racemes. The plant generally grows to 20–60 centimeters in height and produces narrow silique seed pods that split open at maturity to release small brown seeds. <em>Erucastrum gallicum</em> often thrives in nutrient-poor, well-drained soils and is considered a weed in some agricultural regions. Biological traits of this species remain relatively poorly documented in detail beyond basic morphological and distributional data available in the scientific literature.
