Germany – Deutschland

Wolves (Canis lupus) are recolonising large swathes of their former European territories after a lengthy absence. This expanding distribution brings wolves to areas of naïve human communities, inflating risks to human-wildlife coexistence. As such, understanding public attitudes and perspectives to wolf return is central to supporting human-wildlife coexistence. Wolves returned to Germany in 2000 and sporadically to Czech Republic in the 1990s, but only few studies have assessed public attitudes. No research from a protected area visitor perspective has been conducted in Europe, despite their importance for outdoor recreation and nature conservation. We conducted face-to-face surveys of visitors, administered by enumerators during 2018–2019 (n = 869) in the Bavarian Forest and Šumava National Parks, which form a transboundary protected area along the German-Czech border, where the first wolves re-established in 2015. Primarily, we applied aspects of attitude theory, focusing on the components of attitudes (ABC Model of Attitudes) to examine support for wolves from national park visitors (locally and nationally) and if the visitors’ attitudes towards wolves differ. We found substantial support for wolves recolonising Germany and Czech Republic (84.5 %), and agreement that wolves belong in these national parks (89.6 %). Attitudes varied most by country of residence, with Czech visitors more supportive than Germans. Transboundary management which recognises the human dimensions of large carnivore conservation is crucial to supporting coexistence. We highlight the importance of understanding the diverse sociocultural backgrounds across Europe which may influence attitudes towards wolves, and nature conservation areas to support long-term transboundary management policies, coexistence goals, and education.

Since 2010, outbreaks of haemorrhagic septicaemia (HS) caused by Pasteurella (P.) multocida capsular type B (PmB) emerged in Germany. In 2017, we noticed a close spatiotemporal relationship between HS outbreak sites and wolf (Canis lupus) territories. Thus, the main objectives of our study were to investigate the molecular epidemiology of German PmB-HS-isolates and to assess the role of wolves as putative vectors of this pathogen. We collected 83 PmB isolates from HS outbreaks that occurred between 2010 and 2019 and sampled 150 wolves, which were found dead in the years 2017 to 2019, revealing another three PmB isolates. A maximum-likelihood-based phylogeny of the core genomes of 65 PmB-HS-isolates and the three PmB-wolf-isolates showed high relatedness. Furthermore, all belonged to capsular:LPS:MLST genotype B:L2:ST122RIRDC and showed highly similar virulence gene profiles, but clustered separately from 35 global ST122RIRDC strains. Our data revealed that German HS outbreaks were caused by a distinct genomic lineage of PmB-ST122 strains, hinting towards an independent, ongoing epidemiologic event. We demonstrated for the first time, that carnivores, i.e., wolves, might harbour PmB as a part of their oropharyngeal microbiota. Furthermore, the results of our study imply that wolves can carry the pathogen over long distances, indicating a major role of that animal species in the ongoing epidemiological event of HS in Germany.

Following massive persecution and eradication, strict legal protection facilitated a successful reestablishment of wolf packs in Germany, which has been ongoing since 2000. Here, we describe this recolonization process by mitochondrial DNA control-region sequencing, microsatellite genotyping and sex identification based on 1341 mostly non-invasively collected samples. We reconstructed the genealogy of German wolf packs between 2005 and 2015 to provide information on trends in genetic diversity, dispersal patterns and pack dynamics during the early expansion process. Our results indicate signs of a founder effect at the start of the recolonization. Genetic diversity in German wolves is moderate compared to other European wolf populations. Although dispersal among packs is male-biased in the sense that females are more philopatric, dispersal distances are similar between males and females once only dispersers are accounted for. Breeding with close relatives is regular and none of the six male wolves originating from the Italian/Alpine population reproduced. However, moderate genetic diversity and inbreeding levels of the recolonizing population are preserved by high sociality, dispersal among packs and several immigration events. Our results demonstrate an ongoing, rapid and natural wolf population expansion in an intensively used cultural landscape in Central Europe.
