Golden Jackal (Canis aureus) species in Ukraine

An update situation of golden jackal expansion in Ukraine was sent to GOJAGE by our colleague Dr Igor Zagorodniuk from National Museum of Natural History of Ukraine (HERE).

New golden jackal bachelor thesis (Geography)

On 6 of April 2016, Mrs Gianna Jann sustained her thesis regarding the chorology of the golden jackal in Europe. Advisor: Dr. Klaus Schützenmeister at University Köblenz-Landau, Mainz Germany

This is an updated review of the golden jackal biogeography in Europe including the movements and last specimens sightings in Denmark, Netherlands, Poland and Germany.

Injured golden jackal on a bike piste was released after 2 months treatment in NE Italy

by Luca Lapini & Ovidiu Banea

GOJAGE, 3rd of July 2016

On 10th of April 2016 a male golden jackal was injured and quickly translated to ENPA (L'Ente Nazionale per la Protezione degli Animali). After two month and 10 days the jackal was released back to the natural environment, on 21st of June 2016. The specimen was already reported by Lapini, Caldana and Amori in annual report of species trends and evolution (here)

While in countries from Central and Eastern Europe jackals are intensively hunted (Hungary, Serbia, Bulgaria, Romania, Croatia) despite of jackal legal framework that stressed that jackal is communitary interest species and needs that before any population management, an acurate populations monitoring must be done as in case of chamoix, martens or polecats (as they all are listed in the same Vth Annex of EU Habitats Directive). Italy gave us a strong example of how humans are looking for nature equilibrium and species conservation. Evolution and trends of Italian population here (by Lapini, Caldana, Amori, 2016)

The explicit movie (here) of released specimen had more than 30.000 views in 24h. 
GOJAGE expresses the most sincere congratulations to all the members of ENPA and to scientific community involved on this amazing, emotionant and recontiliation with nature event.

Jackal population increases in Italy

by Luca Lapini

A complete analysis of the data at 10-years intervals reveal that its current range is increasing, particularly in the last decade (2005-2015). The overall data indicates that the expansion waves of jackals in Italy are influenced by the already known expansion phases of the species in Europe, but in the last years the populations of north-eastern Italy turned out to be an autonomous source of expansion, thanks both (first) to some long-lasting populations of the Karst of Gorizia and (second) to the formation of new groups dwelling in the centre of Friuli Venezia Giulia Region (Pordenone Province). A poster including new data was presented in Viterbo Italy during the

Lack of jackal competitors in Keoladeo National Park, Rajasthan, India

Aakriti Singh et al published new research regarding food availability and lack of competition in jackal specific ecological systems from Keoladeo National Park, Rajasthan. The work was published on-line on 21st of March 2016 in Mammal Research ISSN: 2199-2401 (Print) 2199-241X (Online).
Using distance sampling method the authors found a density of 14.84 individuals/km2 (5 territorial groups). The authors concluded that the lack of any major competitor and high food resource availability has led to a several fold increase in the population size of golden jackal in a span of 3 decades.
The human activity is high in surroundings of the park (more than 15 villages), inside the park are a lot of ferral cattle which seems to have some effect on the density of jackals. 
In the close future Keoladeo National Park will represent one of the prefered study areas for Crispus NGO Sibiu Romania and GOJAGE when holistic approach of jackal specific ecological systems will be assessed. As we mentioned in previous post (here) bioacoustic monitoring (BAM) is preferable to be performed in this protected natural area in order to compare data with the actual jackal density estimations obtained by distance sampling method.

Jackal in Netherlands?

Golden Jackal C3 Category, first report in Netherlands

Few days ago GOJAGE received the news of a possible jackal in Netherlands. This report was analyzed by Crispus NGO Sibiu Romania with the key-analysis using the new GOJAGE Guidlines. The full report and story here.

New GOJAGE Expert Criteria for new jackal reports assessment

Assessment of golden jackal species (Canis aureus, L.1758) records in natural areas out of their known historic range
Technical Report: GOJAGE  Criteria and Guidelines

Golden jackals show an increasing long-distance dispersal from their known historic geographic range into new areas (Rutkowski et al. 2015). Only in the last years, single golden jackal individuals were reported in Latvia, Lithuania, Poland, Germany or Denmark and a survival cluster of 5 territorial groups (Männil 2016, pers. comm.) is monitored in West Estonia. 

The known historic range of the golden jackal species including large parts of Eurasia and Africa was recently reconsidered since the results of new genetic studies suggest that African golden jackals merit recognition as a full species, as they meet the primary defining criterion of a separate and independently evolving metapopulation lineage (Rueness et al. 2011; Gaubert et al. 2012; Koepfli et al. 2015). Accordingly, it was proposed that the common names ‘‘African golden wolf’’ (Canis anthus) and ‘‘Eurasian golden jackal’’ (Canis aureus) be applied to distinguish these taxa, and to distinguish the former from the Ethiopian wolf (Canis simensis). The African golden wolf is distributed across Africa and includes individuals that have been referred to as Canis lupus lupaster or Canis aureus, sensu lato. Morphologic parallelism of African golden wolves and Eurasian golden jackals may have resulted in their mistaken attribution to a single species (Koepfli et al. 2015)

Over the past two decades evidences northward and westward of the known historic range, mostly the Balkan area, were recorded (Kryštufek et al. 1997; Arnold et al. 2011). The native and naturally colonized range of golden jackals in Europe include now Greece, Albania, Montenegro, Republic of Macedonia, Bosnia-Herzegovina, Serbia, Bulgaria, Romania, Hungary, Croatia, Slovenia, Switzerland, Italy, Austria, Slovakia, Czech Republic, Moldova, Ukraine, Turkey, Caucasus countries, Belarus, Estonia, Latvia, Lithuania, Poland, Germany and Denmark. Central and South-East Europe have now a very important role in the golden jackal species conservation since the European or Caucasian golden jackal (Canis aureus moreoticus, I. Geoffroy Saint-Hilaire, 1835) is known as having its main populations in Bulgaria, Greece, Serbia, Croatia, Hungary and Romania.

The main problem in assessing golden jackal proof in new areas is inexperience due to the novelty and rareness of these situations to this point. This report aims to establish common criteria within European countries and abroad for golden jackal species new records that are reported in areas within naturally colonized range.
