Management

Conservation Actions

Conservation Actions
In Switzerland, this species is listed as Endangered, as some sites have been lost in the Rhone valley, but there are still known from around 40 localities. In Bayern (Germany), it is considered as Critically Endangered. Due to the confusion with Pupilla pratensis, more research is needed on the population and distribution of this species.

Pupilla alpicola

Pupilla alpicola is a species of minute air-breathing land snail, a terrestrial pulmonate gastropod mollusk or micromollusk in the family Pupillidae.

Description[edit]

The shell of this species slightly larger than that of Pupilla muscorum, with slightly more prominent growth lines, around 6 not very convex whorls. The shell apex is flat (in contrast to Pupilla muscorum and Pupilla pratensis). The apertural lip is weak; the cervical callus is weak; there are usually no teeth in the aperture, occasionally a weak parietal tooth. Note the presence of a characteristic gutter-like depression in the external surface of the last whorl, at about 1/4 of the distance from its base. (In oblique light this is also visible in the aperture as a narrow, delicate ridge).[3]

The height of the shell is 2.8–3.3 mm. The width of the shell is 1.75–1.8 mm.[3]

Distribution[edit]

The distribution of Pupilla alpicola includes the Alps and Carpathians.[3] Pupilla alpicola has a scattered distribution; it is rare.[3] Most of its habitats are close to alpine cattle pastures, and this means these habitats are now at risk, because traditional land management is decreasing.[3]

Pupilla alpicola was listed as part of fauna of the Czech Republic for a long time, (as "probably extinct" in Bohemia and critically endangered (CR) in Moravia).[8] After a very similar taxon Pupilla pratensis was elevated to its species level in 2009,[4] the revision showed that Pupilla alpicola does not live in the Czech Republic and all of the supposed records from that country are actually Pupilla pratensis.[9]

Ecology[edit]

Pupilla alpicola occurs in moss, within wet meadows in high alpine regions, mostly in calcareous fens.[3] In Switzerland it lives between 900 and 2500 m altitude.[3]
