Novel microsatellite markers for an endangered freshwater snail,Heleobia atacamensis(Caenogastropoda: Cochliopidae), from the Atacama Saltpan
Author
Abstract
The minute freshwater gastropod Heleobia atacamensis is only known from its type locality
Tilopozo, located at the southern end of the Atacama Saltpan, Antofagasta Region, Chile. It is
classified as Critically Endangered by the national agency, Ministerio del Medio Ambiente de
Chile, due to its restricted distribution. For the first time, we have isolated and evaluated 65
microsatellite markers in 42 specimens of H. atacamensis, successfully characterising 11 as
polymorphic. Cross-amplification testing was successful in three other species of the genus.
As a result, the development and characterisation of these markers could be useful in future
genetic studies of H. atacamensis and its congeners, regarding population structuring,
dispersal patterns and recent demographic history. Furthermore, this information will also be
significant to undertake conservation efforts in this endangered species, since its
environment is highly threatened by lithium mining activities and a global water crisis.
