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.

Coast Dart

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

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.

Coast Dart

Coast dart (Euxoa cursoria) is a medium-sized moth in the family Noctuidae, native to coastal sand dunes and sandy heathland habitats of northern and western Europe, including the United Kingdom, Denmark, the Netherlands, Germany, and Scandinavia. Adults are cryptically patterned in pale buff, grey, and brown tones that match the sandy substrates of their dune habitat, flying at night from late summer into autumn. Larvae feed on the roots of coastal dune grasses and other low-growing plants, overwintering as pupae in loose sand. The genus Euxoa includes numerous 'dart' moths distributed across the northern hemisphere, many of which are habitat specialists tied to open, sandy ground. Coast dart populations have declined significantly across their European range due to the stabilisation and vegetational succession of coastal sand dunes, reduction of bare sand patches through marram grass planting, and recreational disturbance. Despite these pressures, it is assessed as Least Concern by the IUCN. In the United Kingdom, it is classified as a priority species in the Biodiversity Action Plan and is the subject of dune management programmes aimed at maintaining open sand habitat.
