Successful conservation depends on accurate taxonomy. Currently, the taxonomy of canids in Africa, Eurasia and Australasia is unstable as recent molecular and morphological studies have questioned earlier phenetic classifications. We review available information on several taxa of Old World and Australasian Canis with phylogenetic uncertainties (namely, African jackals, Asian wolves and Australasian dogs), in order to assess the validity of suggested scientific names and provide a scientific basis for reaching a taxonomic consensus primarily based on molecular data, but also including morphology, biogeography and behavioural ecology. We identify major knowledge gaps, provide recommendations for future research and discuss conservation implications of an updated taxonomic framework. Recent molecular studies indicate that the former Afro‐Eurasian ‘golden jackal’ represents two distinct lineages, the golden jackal (Canis aureus) from Eurasia and the African wolf (C. lupaster) from Africa. Phylogenetic research also indicates that the side‐striped and black‐backed jackals form a monophyletic group that branched earlier than Canis, Cuon and Lycaon, which should be reassigned to the genus Lupulella as L. adusta and L. mesomelas, respectively. The Himalayan/Tibetan and Indian wolf lineages appear to have diverged earlier and are distinct from all other grey wolves (C. lupus) based on mitochondrial and nuclear genome data. However, until genome‐wide data from multiple individuals across the range clarify relationships with other taxa, we suggest referring to the Himalayan/Tibetan wolf lineage as Canis lupus chanco. We support the currently accepted nomenclature for the Indian wolf Canis lupus pallipes for the wolf populations found on the Indian subcontinent and possibly also in south‐western Asia (exact geographical boundary pending). The information presented here provides a current and consistent taxonomic framework for use by conservationists and other practitioners, but it is also intended to stimulate further research to resolve current uncertainties affecting the taxonomy of Old World canids.

Conflicts have emerged due to range expansions of the golden jackal (Canis aureus) across Europe, characterized by their international conservation status and perceived impacts on livestock and native prey species. Most countries in Central Europe do not yet include the golden jackal in their national list of occurring, native species. Nevertheless, legal obligations arise as soon as golden jackals colonize a particular country. Legal implications of this range expansion were described in past studies from an international perspective. However, they left out specifics on the legal status within any particular country. Therefore, we examine the actual legal status within Central European countries, exemplifying the diverse federal and provincial laws. In particular, we assess the current conservation and hunting laws in Austria’s provinces and discuss them in the context of neighbouring countries to analyse implications for relevant authorities. We found substantial contrasts not only among provinces but also between direct neighbouring countries, impeding efforts for transboundary species conservation and leading to complications regarding the management of this species. Improved procedures for collecting records and hunting-bag data appear necessary for future species assessment on a European level and management on a local level. We recommend a more unified legal system but adjusted to actual golden jackal presence on the regional and cross-border level, combined assessment, or similar management strategies to minimize conflicts, reduce persecution, and clarify legal obligations.

Golden jackal (Canis aureus) monitoring in central Europe generates more interest and becomes increasingly important with the species’ appearance in areas where it was previously unestablished. For genetic monitoring of golden jackals via scat collection, the distinction of jackal scats from those of related species such as the red fox (Vulpes vulpes) is crucial: if done incorrectly, it can falsify diet studies or inflate costs of DNA analyses. In this study, we tested the potential benefits of using domestic dogs to specifically find jackal scats. We used trained scat detection dogs to locate and identify golden jackal scats in an area of dense shrubland, with the species’ presence previously confirmed via bioacoustic monitoring. On a total of 133 km of transects covering at least two golden jackal groups, two human-dog teams found 34 putative golden jackal scats. A total of 26 of these were successfully genetically analysed, of which 19 were attributed to 13 individual golden jackals, an accuracy rate of 73%. Our results show that detection dogs can successfully differentiate golden jackal scats from other species. This tool can be applied to detect golden jackal presence and establish more reliable estimates of group number and size than previously determined through bioacoustic stimulation. By combining both methods, questions about family structures and kinship, seasonal differences in habitat use and territory sizes can be answered. The regular use of detection dogs can present an efficient method to monitor golden jackals on a long-term basis and to learn more about their behaviour and population dynamics.

Recently confirmed expansion of golden jackals (Canis aureus) into countries without any previous records poses questions, one of them focusing on the species potential and possibly varying habitat use. In this study, we investigated the presence and distribution of golden jackals in northern Bosnia and Herzegovina, where knowledge about golden jackal distribution and habitat use is still scarce. We used bioacoustic stimulation as a non-invasive tool to gather data on golden jackal presence. Habitat structures potentially selected by the species were assessed at 92 calling stations and used as input for binary logistic regression models. Our study area covered approximately 1150 km², and bioacoustic stimulation within this area resulted in an estimated minimum relative group density of 3.5 territorial groups per 100 km². We found territorial groups at distances between 15 and 38 km southwards from the river Sava but always within a maximum range of 3 km to perennial watercourses. Habitat analysis identified shrub vegetation and pastures as structures with a significant effect on the presence of resident golden jackals. Probability that golden jackals answered at calling stations increased with increasing surface area covered with pastures and shrubs. Distances between golden jackal territories and the nearest human settlement were relatively small. Our results indicate that structures like transitional woodland-shrubs and pastures, together with other potential influencing factors like local agricultural practices, low hunting pressure, diverse natural and anthropogenic food sources, could have benefited the settlement of golden jackals in the northern lowlands of Bosnia and Herzegovina.

Sexual dimorphism is a widespread phenomenon among mammals, including carnivorans. While sexual dimorphism in golden jackals (Canis aureus) has been analysed in the past, in the related and apparently convergent canid, the African wolf (Canis lupaster), it is poorly studied and showed to be relatively small. Previously, sexual size dimorphism (SSD) research in these species was mostly based on skull and body measurements. In our study, we also included dental measurements, namely the diameter of the canine. We used 11 measured sections of 104 adult specimens, comprising 61 golden jackal and 43 African wolf skulls. Data analyses were carried out through logistic regression and conditional inference trees (CIT). To compare the results of SSD to other species, sexual dimorphism indices (SDI) were calculated. Golden jackals and African wolves show significant sexual size dimorphism, both in cranial and dental size. The logistic regression revealed that the mesiodistal diameter of the upper canine is most effective in discerning the sexes. The difference in the calculated SDI of the canine diameter between the sexes amounted to 8.71 in golden jackals and 14.11 in African wolves, respectively—with regional diversity. Thus, the canine diameter is an important measure to investigate SSD as well as an easy tool to apply in the field.

The golden jackal (Canis aureus) is remarkably flexible in terms of behaviour. This is advantageous to the range expansion of the species to northern and western Europe. Despite the widespread distribution of the golden jackal, many aspects of its behaviour are still poorly known. In this study, we have aimed to improve our general understanding of golden jackal social behaviour by monitoring one family group of a unique insular population living on Samos (Greece) using camera trap data over a study period of 9 months. Successful identification of individual golden jackals based on visual characteristics, determination of the dominance hierarchy and social network analyses has allowed us to gain insights into the group's social organisation, mating system and social structure determined by social relationships. We revealed the studied family group to be relatively stable, consisting of a dominant adult pair and one or two generations of their offspring. Some major changes occurred during the breeding season in terms of social behaviour, group composition and structure. A total of six pups were born, which were cared for by both dominant adults as well as one male and one female yearling who stayed as helpers at the nest. Both the dominant female and the female yearling showed signs of lactation, suggesting either a case of pseudopregnancy or allonursing. Using non‐invasive methods combined with individual identification based on coat colouration patterns, this research contributes to our understanding of the social behaviour of the golden jackal population on Samos in Europe and, by extension, of the species as a whole.
