“…Occurrences of all Arctic Oeneis species (Region C, Table S1) within Beringia support a primary refugial importance of this area for species survival (Yannic et al, 2014). Beringia was ice-free during the whole Pleistocene and served as refugium for mammals (Hope et al, 2013), plants (Eidesen et al, 2013) and other insects (Elias et al, 2000).…”

The interactions of ecological preferences and geographical speciation processes in montane and Arctic regions are relatively well studied (Todisco et al, 2012;Eidesen et al, 2013;Yannic et al, 2014), but mainly using plants and birds as models (e.g. Drovetski, 2003;Kadereit and Baldwin, 2012;Fjeldsa, 2013).…”

Both geographical and ecological speciation interact during the evolution of a clade, but the relative contribution of these processes is rarely assessed for cold-dwelling biota. Here, we investigate the role of biogeography and the evolution of ecological traits on the diversification of the Holarctic arcto-alpine butterfly genus Oeneis (Lepidoptera: Satyrinae). We reconstructed the molecular phylogeny of the genus based on one mitochondrial (COI) and three nuclear (GAPDH, RpS5, wingless) genes. We inferred the biogeographical scenario and the ancestral state reconstructions of climatic and habitat requirements. Within the genus, we detected five main species groups corresponding to the taxonomic division and further paraphyletic position of Neominois (syn. n.). Next, we transferred O. aktashi from the hora to the polixenes species group on the bases of molecular relationships. We found that the genus originated in the dry grasslands of the mountains of Central Asia and dispersed over the Beringian Land Bridges to North America several times independently. Holarctic mountains, in particular the Asian Altai Mts. and Sayan Mts., host the oldest lineages and most of the species diversity. Arctic species are more recent, with Pliocene or Pleistocene origin. We detected a strong phylogenetic signal for the climatic niche, where one lineage diversified towards colder conditions. Altogether, our results indicate that both dispersal across geographical areas and occupation of distinct climatic niches promoted the diversification of the Oeneis genus..

“…The decline of the iconic non-migratory woodland caribou (Rangifer tarandus caribou) ( Figure 1) in North America can be attributed to habitat alteration and climate change, among other environmental stressors (e.g., Vors & Boyce, 2009;Yannic et al, 2014). Woodland caribou were historically found across much of North America's boreal forests, but their populations and ranges have declined drastically since European settlement (de Vos & Peterson, 1951;Bergerud, 1974).…”

“…Projected changes in air temperatures and precipitation can influence caribou population dynamics both directly and indirectly. For example, climate change may lead to shifts in the habitat suitability and distribution of caribou populations (Sharma et al, 2009;Yannic et al, 2014;Murray et al, climate change on future woodland caribou occurrence in Ontario that incorporates the uncertainty from all 126 GCMs.…”

Habitat alteration and climate change are two important environmental stressors posing increasing threats to woodland caribou, Rangifer tarandus caribou, in Ontario. Our first objective was to identify the importance of linear features, habitat, and climate on the occurrence of woodland caribou during the winter season using over 30 years of records . Our second objective was to forecast the impacts of climate change on the future occurrence and range of woodland caribou. Woodland caribou occurrence and environmental data collected during 1980 to 2012 were obtained from the Ontario Ministry of Natural Resources (OMNR). Logistic regression models were used to identify the importance of linear features, habitat, and climate on woodland caribou. We then forecast future caribou occurrences using 126 future climate projections. Woodland caribou preferred coniferous forests and mixed forests that tended to be associated with increased lichen coverage, and regions with colder winters. Woodland caribou also avoided anthropogenically disturbed regions, such as areas associated with high road density or developed areas. Caribou range extent was projected to contract by 57.2-100% by 2050 and 58.9-100% by 2070. Furthermore, all 126 climate change scenarios forecast a range loss of at least 55% for woodland caribou in Ontario by 2050. We project complete loss of woodland caribou in Ontario if winter temperatures increase by more than 5.6°C by 2070. We found that woodland caribou in Ontario are sensitive to changes in climate and forecasted that an average of 95% of Ontario's native woodland caribou could become extirpated by 2070. The greatest extirpations were projected to occur in the northernmost regions of Ontario as well as northeastern Ontario, while regions in western Ontario were projected to have the lowest rates of extirpation. This underscores the importance of mitigating greenhouse gases as a means to protect this iconic species.
