“…, Andersen et al. , Harms & Nowak unpublished data). Future regular immigration and/or continuous wolf presence in central and western Europe is considered likely, and is expected to result in an extension of the currently implemented non‐invasive genetic monitoring programmes to understand dispersal routes in the coming years.…”

1.Following protection measures implemented since the 1970s, large carnivores are currently increasing in number and returning to areas from which they were absent for decades or even centuries. Monitoring programmes for these species rely extensively on non-invasive sampling and genotyping. However, attempts to connect results of such studies at larger spatial or temporal scales often suffer from the incompatibility of genetic markers implemented by researchers in different laboratories. This is particularly critical for long-distance dispersers, revealing the need for harmonized monitoring schemes that would enable the understanding of gene flow and dispersal dynamics. 2. Based on a review of genetic studies on grey wolves Canis lupus from Europe, we provide an overview of the genetic markers currently in use, and identify opportunities and hurdles for studies based on continent-scale datasets. 3. Our results highlight an urgent need for harmonization of methods to enable transnational research based on data that have already been collected, and to allow these data to be linked to material collected in the future. We suggest timely standardization of newly developed genotyping approaches, and propose that action is directed towards the establishment of shared single nucleotide polymorphism panels, next-generation sequencing of microsatellites, a common reference sample collection and an online database for data exchange. 4. Enhanced cooperation among genetic researchers dealing with large carnivores in consortia would facilitate streamlining of methods, their faster and wider adoption, and production of results at the large spatial scales that ultimately matter for the conservation of these charismatic species.

“…A female-wolf was hit by a car in 2012 at the very western edge of Beskydy area, probably after some time the animal had spent in large forested patches in Beskydy [72], suggesting a wolf was only passing through the area rather than settling. On the contrary, instead of long-distance dispersal through human-dominated landscape typical of wolves [73,74], lynx prefer to settle down in neighbouring vacant territories [75]. The lynx population in Besykydy has been stable since the 1980s [33,35] and the species is fully protected in Slovakia.…”

The conservation and management of wolves Canis lupus in the periphery of their distribution is challenging. Edges of wolf distribution are characterized by very few and intermittent occurrences of individuals, which are modulated by multiple factors affecting the overall population such as human-caused mortality, management targets and food availability. The knowledge of population dynamics in the edges becomes crucial when hunting takes place nearby the edges, which may preclude population expansion. Here, using as example the occurrence of wolves in the Beskydy Mountains (Czech-Slovak border), which are the edge distribution of the wolf and Eurasian lynx Lynx lynx populations in the West Carpathians, we explored how food availability and hunting in the Slovakian core area affected the dynamics of wolves in the edges of this population. During 2003–2012, we monitored large carnivore occurrence by snow-tracking surveys and tested potential differences in the occurrence of these species in Beskydy Mountains and potential mechanisms behind detected patterns. Despite the proximity to the core area, with several wolf reproductions being confirmed at least in recent years, the wolf was a very rare species in Beskydy and was recorded 14 times less often than the lynx. The expected abundance of wolves in the Beskydy Mountains was inversely related to prey availability in the Slovakian core area. Wolf hunting the year before influenced the expected abundance of wolves in Beskydy area. We discuss how different life histories and legal status of both species probably account for most of the observed difference of occurrence at range margins.

“…The surge of large carnivores, reaching countries in northern Europe from breeding areas in central Europe, is a recent development that appears to be caused by reduced hunting resulting from effective wildlife protection ( 1 , 7 ). This migration may facilitate the spread of vectors and zoonotic pathogens into new regions.…”

“…Second, the migrations must be rapid enough for the ticks to remain attached to the migrating carnivores during the entire migration. Individual gray wolves are indeed capable of migrating distances of 800–1,200 km within a short period; the first wolf known to arrive in northern Jutland has been genetically traced to the border area between Germany, the Czech Republic, and Poland, >800 km away from Denmark ( 1 ). …”
