Intercourse and ages of the new necropsied personal ways its migrant standing

Into 13th , a masculine canid are found deceased next to the path no. 122, involving the towns off Krajnik Dolny and you will Ognica into the north-west Poland (N 8, Age 6) (Figs. dos and you will 3). The latest necropsy demonstrated comprehensive hematomas and a smashed head, an indication out of a path casualty.

System specifications was in fact in the variety on species and you may was in fact because go after: human anatomy size-10.six kilogram, head and body duration-85.0 cm, end length-twenty-four.5 cm, neck top-48.0 cm, hind foot length-sixteen.0 cm, ear canal length-8.0 cm. Age the animal is calculated because the 1 year old. Finish color, human body proportions (specifically period of the fresh new end) (Fig. 3) additionally the exposure out-of connate shields to your medial digits off the latest forelimbs (Fig. 1) signify the pet try a golden jackal Canis aureus.

For genetic identity, i analysed a great 640 b.p. fragment of your mtDNA D-circle. A sequence taken from the newest inactive private found in north-western Poland are similar having a series away from a guide sample of your wonderful jackal collected inside the south Ukraine. The newest sequence was also weighed against those found in GenBank and you can definitely acquiesced by Great time due to the fact a great fragment of one’s mtDNA D-cycle of fantastic jackal. Genetic investigation has therefore affirmed the dead men included in north-western Poland is a golden jackal.

One or two most other observations out-of jackal, affirmed by the photographic documentation, result from eastern Poland (550 and you will 620 km regarding the location out of dry jackal). The original images observance was developed to the first near Gugny payment (N 52, Age 19) from the Biebrza lake valley of the Podlasie area inside the north-eastern Poland (Figs. dos and you may 4). Another photos observation, of tenth , arises from Chmielne near Piszczac community (N 80, Age 09) into the east Poland (Figs. dos and you may 5). Each other snap anyone had dimensions and you will coat color typical on fantastic jackal.


The fresh dry jackal used in northern-western Poland together with a few other better-reported observations away from east Poland inform you new sheer expansion of your fantastic jackal towards Poland, probably out-of various other advice. These records, plus a good amount of unconfirmed observations from fantastic jackal from in other places in the Poland, not merely near the nation borderline, indicate growing colonization out of Poland of the variety. Having less people findings out of south Poland, where jackals had been registered nearby the Polish border inside neighbouring regions, and you can seen extension in the western and you can east, recommend that the newest mainly forested Carpathian Hills may function a shield on the give of species.

A whole homology among them 640 b.p. fragments of your own mtDNA D-cycle of jackal out-of north-west Poland and another with similar haplotype regarding Ukrainian populace most likely indicates an eastern source associated with the private; yet not, it will take further data.

Practical question are: gets the wonderful jackal already be created in Poland?

Race having indigenous purple foxes (Vulpes vulpes) and invasive raccoon pet (Nyctereutes procyonoides), which inhabit similar habitats (unlock section, wetlands, lake valleys) and you may overlap within their food designs (rats or rodents, carrion), also consequences into the rats, brownish hare and you will roe deer can probably be expected (Jedrzejewska and Jedrzejewski 1998; Lanszki and you will Heltai 2002; Kidawa and Kowalczyk 2011; ).

All of our conclusions have demostrated the newest urgent need influence new reputation from the golden jackal within the Poland. As there is no proof to your person advent of jackal in order to Poland or elsewhere, it can’t be addressed just like the an enthusiastic alien varieties (Trouwborst mais aussi al. 2015). The fresh new wonderful jackal try listed in Habitats Directive Annex V, that covers types of neighborhood appeal, whoever consuming this new wild and exploitation is subject to government procedures. Although not, with regards to the Directive terms, they need to also be handled within beneficial maintenance position. It indicates necessity of species defense at the present condition.
