The Arctic fox (Vulpes lagopus L.) is listed as extinct in Finland, endangered Sweden and critically Norway. Around 2000 there were only 40–60 adult individuals left, prompting the implementation of conservation actions, including a captive breeding programme founded from wild-caught pups. initial trials failed, probably because stress among animals, was radically changed 2005. Eight large enclosures within species’ historical natural habitat established, which had positive effect all pairs...
Abstract Habitat fragmentation may affect species distributions through, for example, altered resource availability and shifts in interactions. Fragmentation by roads has had negative impacts on Fennoscandian alpine ecosystems, with reduction of habitats connectivity species. Concurrently, infrastructure development causes influx subsidies through roadkills litter, which facilitate expansion boreal scavenging species, such as the red fox Vulpes vulpes , intensify interactions Hence,...
Abstract Thiamine deficiency can result in life‐threatening physiological and neurological complications. While a thiamine‐deficient diet may the onset of such symptoms, presence thiaminase – an enzyme that breaks down thiamine is very often cause. In instances, counteracts bioavailability uptake thiamine, even when food‐thiamine levels are adequate. Here, we report on case failed reproduction seven Arctic fox ( Vulpes lagopus ) breeding pairs kept at captive facility, including presentation...
Large carnivores influence ecosystem dynamics in multiple ways, for example, by suppressing meso-carnivores and providing carrions smaller scavengers. Loss of large is suggested to cause meso-carnivore increase expansion. Moreover, competition between may be modified the presence larger carnivores. In tundra ecosystems, smallest meso-carnivore, Arctic fox, has experienced regional declines, whereas its competitively superior congener, red increased, potentially due changes abundance apex...
Spatial capture-recapture modelling (SCR) is a powerful tool for estimating density, population size, and space use of elusive animals. Here, we applied SCR to non-invasive genetic sampling (NGS) data estimate red fox (Vulpes vulpes) densities in two areas boreal forest central (2016-2018) southern Norway (2017-2018). Estimated were overall lower the study area (mean = 0.04 foxes per km
Abstract Scavengers can have strong impacts on food webs, and awareness of their role in ecosystems has increased during the last decades. In our study, we used baited camera traps to quantify structure winter scavenger community central Scandinavia across a forest–alpine continuum assess how climatic conditions affected spatial patterns species occurrences at baits. Canonical correspondence analysis revealed that main habitat type (forest or alpine tundra) snow depth was determinants...
Selection for crypsis has been recognized as an important ecological driver of animal colouration, whereas the relative importance thermoregulation is more contentious with mixed empirical support. A potential thermal advantage darker individuals observed in a wide range species. Arctic animals that exhibit colour polymorphisms and undergo seasonal moults are interesting study subjects testing two alternative hypotheses: demographic performance different morphs might be differentially...
Translocation of captive-bred animals has become a widespread conservation practice to counteract species extinctions. We analyse and discuss the apparent success shortcomings Arctic fox (Vulpes lagopus) reintroductions in alpine tundra areas Norway. followed fate 915 foxes between 2007 2020 estimated survival reproductive released foxes, compared wild-born descendants. Relationship abundance small rodents, population size, age were explored. Overall, probability breeding similar positively...
Abstract Concern has been raised regarding red fox ( Vulpes ) population increase and range expansion into alpine tundra, directly indirectly enhanced by human activities, including carrion supply, its negative impact on native fauna. In this study, we used cameras bait stations hunting remains to investigate how spatiotemporal patterns of scavenging were influenced abundance accessibility live prey, i.e., small rodent cycles, snow depth, primary productivity. We found contrasting between...
Abstract Emerging wildlife diseases often comes with negative cultural and economic impact. Limiting disease spread is a recurrent goal challenge, but the efficacy of various mitigation measures rarely assessed. Chronic wasting (CWD) lethal among cervids that was discovered alpine reindeer ( Rangifer tarandus ) in Nordfjella mountain range Norway 2016. After de‐population, entire fallowed to avoid re‐emergence from environmental pathogen reservoirs. This involved installing perimeter fences...
Abstract For many species, the ability to rapidly adapt changes in seasonality is essential for long‐term survival. In Arctic, seasonal moulting a key life‐history event that provides year‐round camouflage and thermal protection. However, increased climatic variability of events can lead phenological mismatch. this study, we investigated whether winter‐white (white morph) winter‐brown (blue Arctic foxes ( Vulpes lagopus ) could adjust their winter‐to‐summer moult match local environmental...
Abstract Dedicated conservation efforts spanning the past two decades have saved Fennoscandian Arctic fox ( Vulpes lagopus ) population from local extinction, and extensive resources continue to be invested in species' management. Although increasing, populations remain isolated, small are not yet viable longer term. An understanding of causes mortality consequently important optimize ongoing actions.
