Wild Reindeer

Three major herds of wild reindeer (Rangifer tarandus tarandus L.), totaling over 200,000 animals, occur in the tundra and taiga of northern Yakutia. These herds have been expanding since the late 1950s and now occupy most of their historic range. In addition, several thousand wild reindeer occupy the New Siberian Islands and adjacent coastal mainland tundra, and there are about 60,000 largely sedentary forest reindeer in mountainous areas of the southern two-thirds of the province. Wild reindeer are commercially hunted throughout the mainland, and the production of wild meat is an important part of the economy of the province and of individual reindeer enterprises which produce both wild and domestic meat.

Conventional Picture

AbstractThe caribou/wild reindeer (Rangifer tarandus) has been a major resource for many human populations in northern North America and Eurasia for tens of thousands of years. The species is generally represented by prehistorians as providing an ample, easily exploited, and highly reliable resource base for humans. In this paper a number of specific assumptions leading to this view are examined in the light of new data on North American caribou and caribou-hunting Eskimo groups. The conventional picture is found to be largely untenable.

Wild Reindeer

We tested whether sunlight and insect harassment were important proximate factors (Zeitgebers) controlling feeding and lying patterns of wild reindeer (Rangifer tarandus tarandus) in summer. With no insect harassment, feeding and lying each exhibited a polycyclic rhythm with, on average, 4 bouts at equal intervals during each 24-h period (unit-sum constraints in a polycyclic rhythm). When insects were absent, the activity percentages were 50 ± 4% feeding (mean ± SE) and 33 ± 4% lying for daytime and 44 ± 3% feeding and 47 ± 4% lying for nighttime, i.e., the percentage of time spent feeding was equal for daytime and nighttime (nychthemeral), while for lying it was not. With insects present, percentages of time spent feeding and lying were 18 ± 3 and 13 ± 3% for daytime and 45 ± 8 and 41 ± 8% for nighttime, respectively, i.e., neither feeding nor lying exhibited a nychthemeral pattern. During periods of insect harassment, 24-h feeding patterns had no cyclic rhythm, whereas lying remained cyclic, but the percentages of time spent lying during peak bouts (amplitude) and at peak duration (period) were unequal between night and day. Reindeer did not attune their activity to the set points of sunrise and sunset (not crepuscular), demonstrating that daylight is most likely not a powerful Zeitgeber for reindeer during summer.

Abstract Reindeer herding is traditional in Tuva, Russia. This region is located in the southern part of the country, on the border with Mongolia and isolated from the other reindeer herding areas of Russia. During the last three decades, the census population size of Tuva reindeer has decreased drastically, from 15,000 to 1,500 heads. The aim of our study was to assess genetic characteristics of Tuva population of reindeer. Samples of Tuva reindeer (n = 12) were genotyped using Illumina BovineHD BeadChip. To perform the comparison with other ecotypes of domestic reindeer we added samples of all the breeds, which are officially recognized in Russia: the Chukotka (n = 12), the Nenets (n = 31), the Even (n = 12) and the Evenk from Yakutia (n = 12) and Krasnoyarsk region (n = 19). Reindeer from Mongolia (n = 11) as well as the wild reindeer from Yakutian and Taimyr tundra (n = 20), and Baikal and Amur taiga (n = 9) were added to our dataset. After quality control, 7,202 SNPs were selected for subsequent analyses. On PCA plot Tuva reindeer were clustered together with Mongolian reindeer. The FST genetic distance was lowest between these two groups – 0.039 comparing to FST values between Tuva and other groups of domestic reindeer, which ranged from 0.092 (the Evenk from Yakutia) to 0.137 (the Chukotka) and were highest between Tuva and wild reindeer populations (0.146). Allelic richness was lowest in Mongolia (1.288±0.004) and Tuva reindeer (1.301±0.004). In other breeds this parameter ranged from 1.323±0.004 (the Chukotka) to 1.356±0.004 (the Evenk from Yakutia). In our study, it was shown that reindeer from Tuva do not belong to any official breed of Russia and genetically are very close to Mongolian ecotype. Our results should be considered at developing programs for restoration of Tuva reindeer. This work was supported by Russian Science Foundation grant 16-16-10068-P

Wild Reindeer

More than others, arctic ecosystems are affected by consequences of global climate changes. The herbivorous plays numerous roles both in Scandinavian natural and cultural landscapes (Forbes et al., 2007). Wild reindeer (<i>Rangifer tarandus</i> L.) herds in Hardangervidda plateau (Norway) constitute one of the isolated populations along Fennoscandia mountain range. The study aims to understand temporal and spatial variability of intra- and inter-annual home ranges extent and geophysical properties. We then characterize phenological variability with Corine Land Cover ecological habitat assessment and bi-monthly NDVI index (MODIS 13Q1, 250&amp;thinsp;m). Thirdly, we test relationships between reindeer’s estimated densities and geophysical factors. All along the study, a Python toolbox (“GRiD”) has been mounted and refined to fit with biogeographical expectancies. The toolbox let user’s choice of inputs and facilitate then the gathering of raster datasets with given spatial extent of clipping and resolution. The grid generation and cells extraction gives one tabular output, allowing then to easily compute complex geostatistical analysis with regular spreadsheets. Results are based on reindeer’s home ranges, associated extent (MODIS tile) and spatial resolution (250&amp;thinsp;m). Spatial mismatch of 0.6&amp;thinsp;% has been found between ecological habitat when comparing raw (100&amp;thinsp;m<sup>2</sup>) and new dataset (250&amp;thinsp;m<sup>2</sup>). Inter-annual home ranges analysis describes differences between inter-seasonal migrations (early spring, end of the summer) and calving or capitalizing times. For intra-annual home ranges, significant correlations have been found between reindeer’s estimated densities and both altitudes and phenology. GRiD performance and biogeographical results suggests 1) to enhance geometric accuracy 2) better examine links between estimated densities and NDVI.

Separate Population

The Sundrun wild reindeer (Rangifer tarandus) herd was recognized as a separate population during the 1950s. Since then, the herd has ranged over an area of approximately 180 000 km2 between the Indigirka and Kolyma Rivers in northeastern Yakutia. Population dynamics and movements were investigated between 1987 and 1997. During this period, the population estimates ranged from 25 000 to 45 000 reindeer, the sex ratio averaged 55 bulls:100 cows, and the percentage of calves in the herd ranged between 17% and 25%. The main routes of seasonal migrations, wintering areas, and the location of calving areas are discussed.
