Data from: Reproduction as a bottleneck to treeline advance across the circumarctic forest tundra ecotoneCarissa D. Brown, Geneviève Dufour-Tremblay, Ryan G. Jameson, Steven D. Mamet, Andrew J. Trant, Xanthe J. Walker, Stéphane Boudraeu, Karen A. Harper, Greg H.R. Henry, Luise Hermanutz, Annika Hofgaard, Ludmila Isaeva, G. Peter Kershaw, Jill F. Johnstone & Gregory H. R. Henry
The fundamental niche of many species is shifting with climate change, especially in sub-arctic ecosystems with pronounced recent warming. Ongoing warming in sub-arctic regions should lessen environmental constraints on tree growth and reproduction, leading to increased success of trees colonising tundra. Nevertheless, variable responses of treeline ecotones have been documented in association with warming temperatures. One explanation for time lags between increasingly favourable environmental conditions and treeline ecotone movement is reproductive limitations caused by low...
Data from: Dispersal of Amur tiger from spatial distribution and genetics within the eastern Changbai mountains of ChinaYao Ning, Aleksey V. Kostyria, Jianzhang Ma, Marina I. Chayka, Valentin Yu Guskov, Jinzhe Qi, Irina N. Sheremetyeva, Wang Meng & Guangshun Jiang
Population dispersal and migration often indicate an expanded habitat and reduced inbreeding probability, and to some extend reflects improvement in the condition of the population. The Amur tiger population in the northern region of the Changbai mountains in China mostly distributes along the Sino-Russian border, next to the population in southwest Primorye in Russia. The successful dispersal westward and trans-boundary movement are crucial for the persistence of the Amur tiger in this area. This study...
The Eneolithic Botai culture of the Central Asian steppes provides the earliest archaeological evidence for horse husbandry, ~5500 years ago, but the exact nature of early horse domestication remains controversial. We generated 42 ancient-horse genomes, including 20 from Botai. Compared to 46 published ancient- and modern-horse genomes, our data indicate that Przewalski’s horses are the feral descendants of horses herded at Botai and not truly wild horses. All domestic horses dated from ~4000 years ago...
Data from: Winter coat color polymorphisms identify global hotspots for evolutionary rescue from climate changeL. Scott Mills, Eugenia V. Bragina, Alexander V. Kumar, Marketa Zimova, Diana J.R. Lafferty, Jennifer Feltner, Brandon M. Davis, Klaus Hacklander, Paulo C. Alves, Jeffrey M. Good, Jose Melo-Ferreira, Andreas Dietz, Alexei V. Abramov, Natalia Lopatina & Kairsten Fay
Maintenance of biodiversity in a rapidly changing climate will depend on the efficacy of evolutionary rescue, whereby population declines due to abrupt environmental change are reversed by shifts in genetically-driven adaptive traits. However, a lack of traits known to be under direct selection by anthropogenic climate change has limited the incorporation of evolutionary processes into global conservation efforts. In 22 vertebrate species, some individuals undergo a seasonal color molt from summer brown to winter white...
Near Eastern Neolithic farmers introduced several species of domestic plants and animals as they dispersed into Europe. Dogs were the only domestic species present in both Europe and the Near East prior to the Neolithic. Here, we assessed whether early Near Eastern dogs possessed a unique mitochondrial lineage that differentiated them from Mesolithic European populations. We then analysed mitochondrial DNA sequences from 99 ancient European and Near-Eastern dogs spanning the Upper Palaeolithic to the Bronze...
Data from: Cytoskeleton structure and total methylation of mouse cardiac and lung tissue during space flightIrina V. Ogneva, Sergey S. Loktev & Vladimir N. Sychev
The purpose of this work was to evaluate the protein and mRNA expression levels of multiple cytoskeletal proteins in the cardiac and lung tissue of mice that were euthanized onboard the United States Orbital Segment of the International Space Station 37 days after the start of the SpaceX-4 mission (September 2014, USA). The results showed no changes in the cytoskeletal protein content in the cardiac and lung tissue of the mice, but there were significant...
Data from: Effect of Hf-doping on electrochemical performance of anatase TiO2 as an anode material for lithium storageSergey V. Gnedenkov, Sergey L. Sinebryukhov, Veniamin V. Zheleznov, Denis P. Opra, Elena I. Voit, Evgeny B. Modin, Alexander A. Sokolov, Alexander Yu Ustinov, Valentin I. Sergienko & Alexander Yu. Ustinov
Hafnium-doped titania (Hf/Ti = 0.01; 0.03; 0.05) had been facilely synthesized via a template sol-gel method on carbon fiber. Physicochemical properties of the as-synthesized materials were characterized by X-ray diffraction, Raman spectroscopy, scanning electron microscopy, energy-dispersive X-ray analysis, scanning transmission electron microscopy, X-ray photoelectron spectroscopy, thermogravimetry analysis, and Brunauer−Emmett−Teller measurements. It was confirmed that Hf4+ substitute in the Ti4+ sites, forming Ti1–xHfxO2 (x = 0.01; 0.03; 0.05) solid solutions with an anatase crystal structure. The...
Data from: Effects of carbon-based nanomaterials on seed germination, biomass accumulation and salt stress response of bioenergy cropsKamal Pandey, Mohamed H. Lahiani, Victoria K. Hicks, Keith Hudson, Micah J. Green, Mariya Khodakovskaya & M. Keith Hudson
Bioenergy crops are an attractive option for use in energy production. A good plant candidate for bioenergy applications should produce a high amount of biomass and resist harsh environmental conditions. Carbon-based nanomaterials (CBNs) have been described as promising seed germination and plant growth regulators. In this paper, we tested the impact of two CBNs: graphene and multi-walled carbon nanotubes (CNTs) on germination and biomass production of two major bioenergy crops (sorghum and switchgrass). The application...
Dogs were present in the Americas prior to the arrival of European colonists, but the origin and fate of these pre-contact dogs are largely unknown. We sequenced 71 mitochondrial and seven nuclear genomes from ancient North American and Siberian dogs spanning ~9,000 years. Our analysis indicates that American dogs were not domesticated from North American wolves. Instead, American dogs form a monophyletic lineage that likely originated in Siberia and dispersed into the Americas alongside people....
