description

Apšuciema kaļķainais zāļu purvs ir Eiropas Biotopu direktīvas biotops ar nozīmīgām dižās aslapes un rūsganās melnceres audzēm, kuru apdzīvo Vertigo ģints pumpurgliemeži, pie tam V. angustior un V. geyeri ir iekļautas Eiropas Biotopu direktīvas II pielikumā. Gliemeži spēj asimilēt vidē esošo kalciju, tāpēc tie ir sastopami tādos biotopos kā kaļķaini purvi. Pētījuma rezultāti liecina, ka Apšuciema purvā ir izveidojušās trīs veģetācijas zonas, kurās mijiedarbība ar pumpurgliemežiem atšķiras. Vislabākie apstākļi bija sūnu dominētajos parauglaukumos, kamēr dižās aslapes dominētajā zonā apstākļi pumpurgliemežiem bija nelabvēlīgi. Elektrovadītspēja un pH liecināja par minerālelementu un to veidoto savienojumu daudzumu izmaiņām, bet augu sugu sastāva un dominances izmaiņas norādīja uz elementu izmaiņām biotopa ietvaros.
