    Parasitic strongyle nemabiome communities in wild ruminants in Sweden

    Wildlife hosts may serve as reservoirs for strongyles, which can be transmitted to domestic livestock. Therefore, studies evaluating nemabiome compositions in wildlife ruminants are of great use in assessing t...

    Measurement of catestatin and vasostatin in wild boar Sus scrofa captured in a corral trap

    Our aim was to analyse the chromogranin A-derived peptides vasostatin and catestatin in serum from wild boar (Sus scrofa) captured in a corral trap. Acute capture-related stress quickly leads to a release of adre...

    Nutritional niche separation between native roe deer and the nonnative fallow deer—a test of interspecific competition

    On an evolutionary time scale, competition for food drives species formation by genetic adaptations to the environment and subsequent niche separation. On a short-term scale, animals use different strategies t...

    Validating a common tick survey method: cloth-dragging and line transects

    Cloth-dragging is the most widely-used method for collecting and counting ticks, but there are few studies of its reliability. By using cloth-dragging, we applied a replicated line transects survey method, in ...

    Wild boar behaviour during live-trap capture in a corral-style trap: implications for animal welfare

    Wildlife traps are used in many countries without evaluation of their effect on animal welfare. Trap-capture of wild animals should minimise negative effects on animal welfare, irrespective of whether the anim...

    Spatial patterns of pathogen prevalence in questing Ixodes ricinus nymphs in southern Scandinavia, 2016

    Tick-borne pathogens cause diseases in animals and humans, and tick-borne disease incidence is increasing in many parts of the world. There is a need to assess the distribution of tick-borne pathogens and iden...
