Declining survival rates of red foxes (Vulpes vulpes) during the first outbreak of sarcoptic mange in Sweden

<p>Rapid declines in red fox (Vulpes vulpes) populations have followed outbreaks of epizootic mange caused by the mite Sarcoptes scabiei. In Sweden, the first outbreak of sarcoptic mange started in 1977/78 and affected the whole country by 1984. Here we used data on number of harvested red foxes from Gävleborg county (18 199 km2) in Sweden between 1970 and 1994. We used data on the prevalence of sarcoptic mange in harvested red foxes from 1974 to 1982. A rapid decline in harvested foxes occurred two to three years after the prevalence of sarcoptic mange first became evident. In the same period, Mark-Recovery data were used to estimate changes in survival rates, and the best model included an effect of age (young or adult) and period (annual) on the survival and recapture probabilities. The analysis was based data from 701 young foxes of which 523 were recovered, and 133 adults of which 131 were recovered. Average annual survival was 0.55 (range=0.53-0.58) for adult and 0.36 (range=0.32-0.39) for young foxes in the three years preceding the outbreak. During the outbreak and the remaining six years of the study, the average survival was reduced to 0.41 (range=0.30-0.48) for adult and to 0.25 (range=0.17-0.30) for young foxes. A population model, based on our results on survival and literature data on fecundity, was developed to project the decline of the fox population. The rate and magnitude of the reduction in the projected population and harvested foxes were similar, with both reduced by almost ninety percent. Harvest statistics indicate the fox population recovered to pre-mange densities in less than 10 years after the first detection of mange indicating a rapid development of resistance in the host. This study shows the importance of long-term population monitoring in combination with large-scale field-experiments to device alternative management options.</p>

Data from: Consequences of repeated sarcoptic mange outbreaks in an endangered mammal population

<p>Diseases and parasites are important drivers of population dynamics in wild mammal populations. Small and endangered populations that overlap with larger, reservoir populations are particularly vulnerable to diseases and parasites, especially in ecosystems highly influenced by climate change. Sarcoptic mange, caused by a parasitic mite (Sarcoptes scabiei), constitutes a severe threat to many wildlife populations and is today considered a panzootic. The Scandinavian arctic fox (Vulpes lagopus) is endangered with a fragmented distribution and is threatened by e.g., red fox (Vulpes vulpes) expansion, prey scarcity and inbreeding depression. Moreover, one of the subpopulations in Scandinavia has suffered from repeated outbreaks of sarcoptic mange during the past decade, most likely spread by red foxes. This was first documented in 2013 and then again 2014, 2017, 2019, 2020 and 2021. We used field inventories and wildlife cameras to follow the development of sarcoptic mange outbreaks in this arctic fox subpopulation with specific focus on disease transmission and consequences for reproductive output. In 2013-14, we documented visual symptoms of sarcoptic mange in about 30% of the total population. Despite medical treatment, we demonstrate demographic consequences where the number of arctic fox litters plateaued and litter size was reduced after the introduction of S. scaibei. Furthermore, we found indications that mange likely was transmitted by a few arctic foxes travelling between several dens, i.e., "super-spreaders". This study highlights sarcoptic mange as a severe threat to small populations and can put the persistence of the entire Scandinavian arctic fox population at risk.</p>
