Habitat

Inhabits temperate broadleaf and mixed forests and Mediterranean forests and woodlands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found across Europe (6 countries) and North America (United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

ハクトウワシ

アメリカの国鳥であり保全の成功を象徴するハクトウワシは翼開長が最大2.4 mに達し、北米全域の水辺近くの森林や湿地に生息する。強力な空中捕食者兼腐肉食者で魚を主食とするが、水鳥や腐肉も捕食する。DDT汚染と狩猟によって1960年代にほぼ絶滅に瀕したが、農薬の使用禁止と絶滅危惧種法の施行により劇的に回復した。

clear glass snail

The Clear Glass Snail is a common name applied to small, translucent land snails, typically in the family Vitrinidae or Zonitidae, characterized by their thin, glassy shells through which the soft body of the animal is often visible. These snails inhabit moist, shaded environments including deciduous woodland, grassland with thick vegetation, and hedgerows across Europe and North America. The thin, transparent shell is often not large enough to completely retract into, leaving the mantle partially exposed, an adaptation that reduces shell weight while maximizing the internal surface area available for gas exchange. Clear glass snails are detritivores and microphages, consuming fungi, algae, decaying plant matter, and occasionally living plant tissue. They are sensitive to desiccation and are most active during wet, cool conditions, retreating under bark, stones, or into leaf litter during dry weather. Several European glass snail species are considered indicators of old, undisturbed woodland habitats with stable microclimatic conditions. Some species in the family Zonitidae have declined due to loss of old woodland, intensive agriculture, and fragmentation of semi-natural habitats. Exact conservation status depends on the specific species intended by the common name.
