Conservation genetics study of huchen in Slovenia recommends river system‐based management and indicates self‐sustainability of the middle Sava population

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 32, Issue 7, Page 1171-1183, July 2022., 2022
Abstract The middle part of the Sava River in Slovenia provides one of the longest free‐flowing habitats for huchen, a threatened species that is also protected by the European Habitats Directive. However, there are plans for the construction of a chain of hydropower plants along this stretch of river.

Cytology, function and dynamics of stem and progenitor cells in decapod crustaceans

Biological Reviews, Volume 97, Issue 2, Page 817-850, April 2022., 2022
ABSTRACT Stem cells play key roles in development, tissue homeostasis, regeneration, ageing and diseases. Comprehensive reviews on stem cells are available for the determinately growing mammals and insects and some lower invertebrates like hydra but are rare for larger, indeterminately growing invertebrates that can live for many decades.

The amount of environmental DNA increases with freshwater crayfish density and over time

Environmental DNA, Volume 4, Issue 2, Page 417-424, March 2022., 2022
Although several assays for the detection of freshwater crayfish have been published, comparably little is known on the relationship between eDNA concentration and crayfish population densities, a pre‐requisite for estimating population size from eDNA measurements.
