This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Across the circumpolar north, many herds of Rangifer have decreased in abundance. In the Canadian central Arctic, the Bathurst herd of barren-ground caribou (Rangifer tarandus groenlandicus) declined from 472,000 ± 72,900 (± 95% confidence interval) caribou in 1986 to 31,900 ± 10,900 caribou in 2009 ...A reduction in winter forage due to forest fires has been suggested as a factor contributing to the decline. I employed a multi-scale study design to identify the influence of vegetation, fire history, snow cover, and predation risk on the occupancy of winter habitats by Bathurst caribou. Between 2008 and 2009, I collected forest stand and understory data at habitats used by caribou, as well as paired control sites. At a larger spatial scale, I used animal location data recorded from 1996 - 2009 to characterize the spatial and temporal distribution of Bathurst caribou on the winter range. At the scale of the feeding patch, caribou foraged in habitats with a high-percentage ground cover, high biomass of lichen, and few or small trees. Similarly, the consensus among the models of habitat selection was that collared caribou avoided areas of the winter range with a high density of burns and favoured older patches of forest characterized by a high percentage of ground cover of lichen and herbaceous forage and a close proximity to lakes and rivers. However, there was considerable use of habitats adjacent to the burn boundary, and some caribou occupied early-seral habitats significantly more than expected. Although the abundance of fruticose (having branched, shrubby thalli) lichens was relatively high (2464 kg/ha) in areas burned within the last 43 - 264 years, my results suggest that an increased incidence and severity of forest fires due to climatic warming could cause a temporary decrease in the habitat available to the Bathurst caribou herd during winter. In the event that reduced lichen availability becomes a limiting or regulating factor for caribou, fire suppression may be necessary to mitigate.

This book was released on 2014 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arctic caribou and reindeer (Rangifer tarandus) are an economically and ecologically important species. Rangifer populations are often affected by nutritional factors. Our ability to monitor nutrient supply to arctic ungulates is presently limited by a lack of techniques to consistently and easily measure availability of specific nutrients and which may disproportionately affect different segments of Rangifer populations. I refined and validated a method to measure availability of specific nutrients including nitrogen (N) and energy to caribou using purified fibrolytic enzymes and acid/pepsin to simulate digestion. I then used this method to measure how availability of nitrogen and energy was altered by anti-nutrients such as indigestible fiber and toxins. Digestible N contents in forages declined to almost zero by the end of the growing season, whereas digestible energy concentrations were still sufficient to meet basic maintenance requirements for caribou by the end of the growing season in shrub and forb forages. Shrubs contained the highest amounts of total N and energy, however this was reduced by fiber and toxins so that shrubs contained the lowest digestible N contents, especially for Betula nana. Graminoids were extremely low in digestible energy content, which may necessitate a high degree of selection among plant parts by herbivores. Dietary choice over long- and short-term periods may be assessed using non-invasive stable isotope techniques, nevertheless, the understanding of how isotopic signatures vary over spatial, temporal, and species-specific scales and how isotopic signatures are changed by digestive processes is limited. Monocot (graminoid) and dicot (browse and forb) forages both differed in values of 13C and 15N, however regional and seasonal shifts in 13C were larger than the differences among forage groups themselves. Forage isotopic signatures also changed after simulated digestive processes, yet this was only significant for species with very low ( 52.6 % N) or very high ( 36.6 % C) digestibilities. These studies suggest that nitrogen may be a limiting nutrient for caribou populations. Persistence of arctic caribou populations in a changing climate may depend, in part, upon continued access to calving grounds, the change in abundance of individual shrub species, and/or the ability of caribou to behaviorally and physiologically cope with increasing amounts of toxins in shrubs.
