Golden jackal population genetic structure in Slovenia

Golden jackal in Slovenia

GOJAGE Journal Club

by Ovidiu Banea

A very interesting study describing the genetic structure of the golden jackal population in Slovenia was performed by Astrid Vik Stronen, Kristijan Tomljanović, Hubert Potočnik, and other researchers from Hungary, Austria, Croatia, and Serbia. It was published recently in Global Ecology and Conservation (Source: here). 

Tissue samples were collected from Slovenia (n =48), Croatia (n =53), Serbia (n =29), and Hungary (n =22) over the past 15 years. Thirteen samples from Slovenia were analysed from saliva.

It was found that a possible origin of recent jackal dispersion in Slovenia corresponds to sources from Serbia and Hungary and not to the Dalmatian cluster as it was hypothesized by the authors. Some results suggested a third cluster centered in northern Hungary.

The study is crucial to understand the golden jackal population movement pattern in Central Europe and new data from the Eastern countries would be of great interest to further explore the species biogeography in Europe. 

Authors: "However, investigation of samples collected south and east of our study area will be required to obtain a better picture of gene flow within the Balkans and beyond, including the Caucasus (Shakarashvili et al., 2020), and can help determine the main routes of jackal range expansion across Europe."
