Summary: The introduction of exotic lodgepole pine has negative effects on reindeer husbandry in northern Sweden, leading to a reduction in forage availability and winter grazing grounds. The presence of lodgepole pine stands significantly decreases lichen cover, which is an important food source for reindeer.

Summary: This study investigates the feasibility of reclaiming abandoned peatlands in Finland as reindeer summer pastures. The results suggest that both mechanical transplanting and sowing seed mixtures can promote the establishment of forage plants, but there are also challenges such as high costs and technical requirements.

Summary: Adenoviruses are responsible for major diseases in various animal species, with deer species known to be affected by adenoviruses 1 and 2. While the former causes high fatality adenovirus hemorrhagic disease in certain deer species, the latter has been linked to fever, cough, and bleeding. Additionally, a novel deer mastadenovirus associated with necrotizing bronchiolitis in captive reindeer was identified for the first time.

Summary: This study reports the development of a SNP-array for the endangered Rangifer tarandus using a multi-platform sequencing approach. A total of 63,336 SNPs were selected from a comprehensive catalog of SNPs detected in diverse populations. This SNP-array design allows for the assessment of genetic metrics related to population structure, inbreeding, and sex determination, and is of great importance for conservation planning.

Summary: The aim of this study was to evaluate the management and feeding practices, as well as the prevalence of endoparasite infections in captive Swiss reindeer. A total of 67 reindeer from eight different farms and zoos were evaluated. The study found that gastrointestinal strongyles were prevalent in 68.6% of the reindeer, with a lower prevalence in reindeer from zoos compared to private farms. This study provides important data for breeders and veterinarians dealing with captive reindeer in Switzerland.

Summary: This study builds a model based on Indigenous and scientific knowledge to investigate the social-ecological system of caribou in the circumpolar North. The findings demonstrate that environmental conditions, caribou demography, and cultural practices affect hunters' ability to meet their needs. This research enhances our understanding of the complex relationships between ecosystems and human well-being.

Summary: The growth of tall woody vegetation in the Arctic, driven by warming, can accelerate climate change through positive feedbacks. Despite local evidence suggesting that large herbivores limit this vegetation shift, it remains uncertain whether herbivory pressure is a significant control on ecosystem structure and functioning at larger, regional scales. Our study on the Yamal Peninsula in West Siberia, using satellite remote sensing and data on reindeer migrations, reveals that higher reindeer herbivory pressure is consistently associated with lower coverage of tall woody vegetation. This suggests that, at current population densities, large herbivores counteract Arctic vegetation responses to climate change over large spatial scales.

Summary: The study found that habitat use decreased within 0.25 km with increasing cumulative disturbance for snow-free and winter seasons, and up to 1 km for spring. Reductions in habitat use in areas with the highest cumulative disturbance within these zones ranged from 92% to 98%. The approach provides novel results and estimates where cumulative effects actually occur, suggesting clustering future human developments within areas of high disturbance where functional habitat use is already lost or highly reduced.

Summary: Improvements of grazing conditions are necessary for reindeer husbandry in northern Sweden due to critically low levels of ground and tree lichen. Adapted forest management can increase ground lichen habitat by 22% within 15 years and retain or increase tree lichen habitat. However, this would result in a decrease in net revenues from wood production by 11-22% compared to current practices.

Summary: This study examines the economic effects of variation in winter conditions on reindeer husbandry by combining a state-of-the-art economic-ecological model with annual reindeer management reports from Finland. The study finds that difficult winters decrease the net revenues of reindeer husbandry but also protect lichen pastures, thereby increasing future net revenues. However, the overall variability of winter conditions decreases the net income of herders, particularly when lichen biomass is low. The study suggests that climate change-induced variability of winter conditions will decrease net revenues in reindeer husbandry, even without the most extreme effects of climate change.

Summary: This study presents data on PRNP variability in reindeer from the Asian part of Russia. The results show the presence of several variations associated with chronic wasting disease (CWD), with resistance-associated variants more common in domesticated reindeer and susceptibility-associated variants primarily found in wild deer populations.

Summary: The study found that Norwegian semi-domesticated reindeer are exposed to hepatitis E virus or a similar virus, with adults showing a slightly higher seroprevalence than calves. There was no influence of gender or latitude on seroprevalence, and a positive association was found between the presence of anti-HEV antibodies and antibodies against other viruses. Further investigations are needed to determine the impact on reindeer health and the potential threat to human health.

Summary: The study found that the population dynamics and reproductive output of wild forest reindeer were influenced by the abundances of wolves and moose, supporting the alternative prey hypothesis. However, the study also acknowledged that the alternative prey hypothesis and apparent competition hypothesis are not mutually exclusive, and the management of the entire ecosystem is crucial for the recovery of wild forest reindeer.

Summary: The study investigates the relationship between bone properties and loading patterns in reindeer, finding that differences in activity may lead to changes in bone quantity and external dimensions. Working and zoo reindeer show differences in bone properties compared to free-ranging/wild reindeer, indicating potential impacts of human interaction on reindeer domestication.

Summary: The aim of this study was to monitor the genetic diversity and population structure of the Tuva-Tofalar reindeer, as well as investigate its genetic relationship with other reindeer breeds. The results revealed a low level of genetic variability in the Tuva population and a shared genetic background with the reindeer in Mongolia. The research showed independent genetic structures in the Tuva population, the Mongolian population, domestic reindeer breeds, and wild reindeer populations, indicating the possibility of independent origins. These findings are important for the conservation and sustainable growth of the Tuva-Tofalar reindeer population, as well as the lives and culture of indigenous peoples.

Summary: This study validated a method of scoring clot density in quarter milk samples and observed elevated clot-density scores clustering within certain cows and cow periods. High clot-density scores appeared in new quarters of the cows over time, indicating that a QMS of 3 could be a reasonable threshold for detecting quarters with abnormal milk that require further attention.
