MEASURES Project: ten countries unite for a common purpose

Managing and restoring aquatic ecological corridors for migratory fish species in the Danube River Basin:

Ten countries along the Danube (Germany, Austria, Slovakia, Slovenia, Hungary, Croatia, Serbia, Romania, Bulgaria and Ukraine) joined forces in an EU-funded project to conserve endangered migratory fish species in the Danube river basin by identifying and improving access to habitats and promoting the establishment of ecological corridors.

Danube is home to some of the most endangered sturgeon populations. Bulgaria and Romania hold the only – still – viable populations of wild sturgeons in the EU. Taking sturgeons and other migratory fish species (e.g. shads, barbel, nase etc.) as flagship species for all migrants of international relevance in the Danube River Basin, MEASURES project wants to identify, map and connect the migratory fish habitats in order to protect and enhance these aquatic ecological corridors.

Two years and counting


In Scriptorium‘s second year of existence, a foundation of its second research focus – the genetic mechanisms of brain regeneration, using the tunicate Ciona intestinalis as a model, was laid.

Check out the project website with regular updates:

and the press coverage in slovene:

The study is part of a broader regeneration-themed research led by William Jeffery from the University of Maryland.

The second anniversary of Scriptorium is therefore celebrated by the successful accomplishment of both primary goals set at its inception:

New project: endangered cave clam Congeria jalzici

The spring of the Krupa river in southeastern Slovenia is the site of one of the biggest ecological disasters in the Dinaric Karst. Between 1962 and 1984 dozens of tons of pure polychlorinated biphenyls (PCBs) were dumped at the waste disposal sites and neighboring dolines by a local condenser factory. They were leached underground, and their concentration in spring water in the 1980s exceeded the US Environmental Protection Agency regulations by up to one thousand (Polič et al., 2000). The undegradable carcinogenic chemicals are still gradually released from the sediments into the groundwater and were detected in the tissues of the population of the olm (Proteus anguinus) residing in the aquifer (Pezdirc et al., 2011). The Krupa spring is also a presumed site of the very rare cave clam Congeria jalzici, although shells and not living animals were found in it (Hudoklin and Ilenič, 2012). Environmental DNA assay for Congeria is being developed to establish if a living population is present behind the spring and to survey the area for additional sites inhabited by the mollusk.


Environmental DNA in subterranean biology

Environmental DNA can be especially useful for determining the presence of animals living in groundwater. Moreover, the eDNA approach can be applied not only in biogeography and conservation of rare and endangered species, but it is efficient also in addressing questions in evolution and taxonomy of the cryptic subterranean fauna.
