Predators are the single most important factor for these losses, whereas restrictions on food availability some years also may cause high mortality. In the past, reindeer herding was challenged by severe infectious diseases, killing hundreds and thousands of animals, and having huge economic and social impact on reindeer herding in Fennoscandia. The general zoo-sanitary situation in Fennoscandia is very favourable for the time being, but reindeer herding is sometimes challenged by disease outbreaks, and diseases play an important role for survival and fitness of reindeer. Reindeer herding is also facing changes and challenges, which also may impact reindeer health and the disease status. Introduction of infectious agents not commonly present in the reindeer population may take place through import of animals, as well as by contact between reindeer, livestock and wildlife. Further, changes in the herding, such as increased feeding, transport, size of herds, animal density and stress load on the animals, may affect the animals ability to cope with infectious diseases. Also changes in weather conditions and climate, such as increased precipitation and mean temperature, may over time lead to restricted availability of pastures, changes in vegetation and changed conditions for parasites and insect vectors. These changes might be especially important for the reproductive success, including fitness of the calves during their first winter. To be able to cope with these changes and their potential impact on reindeer health, increased efforts should be made to gather reference data on health and disease parameters from the different reindeer herding districts, along with epidemiological risk factor analysis. This would increase the ability for the reindeer herding to cope with changes and to continue to produce quality meat products for the market.","PeriodicalId":30034,"journal":{"name":"Rangifer","volume":"32 1","pages":"35-47"},"PeriodicalIF":0.0,"publicationDate":"2013-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71330237","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the second half of the last century, the domesticated reindeer population in Russia shifted dramatically from a maximum of 2.5 million head to a minimum of 1.2. The most important trends were connected to changes in social and economic conditions linked to government directives. Post-Soviet reforms in the 1990s resulted in a nearly 50% reduction in the total number of domesticated reindeer. However in some regions, these political events had the opposite effect. The contrast was due to the abilities of herders to adapt to the new conditions. A detailed analysis of these adaptations reveals an important difference between reindeer-holding enterprises with common ownership (i.e. kolkhozes, sovkhozes, municipal enterprises, etc.) and households with family owned reindeer. The paper concludes that the effect the political context is so large as to conceal the impact of other natural factors on reindeer populations such as climate change. However, a gradual increase of reindeer populations in the north-eastern part of Russia in the 1960s can be associated with changes in atmospheric circulation patterns.","PeriodicalId":30034,"journal":{"name":"Rangifer","volume":"32 1","pages":"19-33"},"PeriodicalIF":0.0,"publicationDate":"2013-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71330226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventeen Sami reindeer herders in four reindeer herding communities in Sweden (“samebyar” in Swedish) were interviewed about plants species considered to be important reindeer food plants in scientific literature. Among 40 plant species, which the informants were asked to identify and indicate whether and when they were grazed by reindeer, they identified a total of 21 plant taxa and five plant groups. They especially recognised species that were used as human food by the Sami themselves, but certain specific forage plants were also identified. Detailed knowledge of vascular plants at the species level was surprisingly general, which may indicate that knowledge of pasture resources in a detailed species level is not of vital importance. This fact is in sharp contradiction to the detailed knowledge that Sami people express for example about reindeer (as an animal) or snow (as physical element). The plausible explanation is that observations of individual plant species are unnecessarily detailed information in large-scale reindeer pastoralism, because the animals graze freely under loose herding and border surveillance.","PeriodicalId":30034,"journal":{"name":"Rangifer","volume":"32 1","pages":"1-17"},"PeriodicalIF":0.0,"publicationDate":"2013-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71330186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
