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.

Colton's Milkvetch

Habitat

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

Ballena jorobada

Entre las ballenas grandes más acrobáticas, las ballenas jorobadas son célebres por sus complejos y estremecedores cantos entonados por los machos durante la temporada reproductiva, que pueden durar horas y evolucionar con el tiempo. Alcanzando 16 metros y 30 toneladas, realizan las migraciones más largas de cualquier mamífero. Se encuentran en todos los océanos y se alimentan de krill y peces pequeños mediante la técnica cooperativa de pesca con red de burbujas.

Colton's Milkvetch

<em>Astragalus coltonii</em>, Colton's milkvetch, is a perennial legume in the family Fabaceae assessed as Least Concern by the IUCN. The genus <em>Astragalus</em> is the largest genus of flowering plants globally, with over 3,000 species distributed primarily in temperate and arid regions of the Northern Hemisphere. <em>Astragalus coltonii</em> inhabits diverse terrestrial environments, typically including semi-arid shrublands, rocky soils, and open desert margins where competition from taller vegetation is limited. Like other milkvetches, this species likely forms root associations with nitrogen-fixing bacteria, enabling it to colonise nutrient-poor substrates and contribute to soil fertility improvement in its habitat. The pinnately compound leaves, pea-type flowers, and inflated seed pods characteristic of the genus are typical features of this species. Milkvetches provide forage for native pollinators and serve as larval host plants for several butterfly and moth species. Some <em>Astragalus</em> species accumulate selenium or alkaloids from the soil, making them toxic to livestock, though the toxicological properties of <em>A. coltonii</em> specifically have not been well characterised. Biological traits of this species remain poorly documented in the scientific literature.
