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.

Clover weevil

Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (8 countries), Europe (12 countries), and North America (Canada, 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.

Clover weevil

The clover weevil (Sitona hispidulus) is a small herbivorous beetle in the family Curculionidae, subfamily Entiminae. Native to the Palearctic region across Europe and Asia, this species has been introduced to North America, where it is now widespread across agricultural regions. Adults and larvae feed on clovers and other legumes in the genus Trifolium and related plants. Adults feed on the leaves, creating characteristic semicircular notches along leaf margins, a feeding pattern typical of Sitona weevils. Larvae feed underground on nitrogen-fixing root nodules, which can reduce the agronomic value of legume crops by damaging the symbiotic Rhizobium bacteria. The clover weevil is consequently regarded as an agricultural pest in clover-growing regions. Adults are grey-brown and densely covered in scales, measuring about 3–5 mm in length. The species overwinters as adults in soil or leaf litter, emerging in spring to feed and reproduce. It inhabits cultivated fields, pastures, meadows, roadsides, and any habitat supporting clover and related legumes. Listed as Least Concern by the IUCN given its wide distribution and abundance.
