Data for the project: Climatic impacts on the availability and transfer of chemical elements through Arctic terrestrial food-chains: a pilot study

Uploaded data contain trace element concentrations measured in various biological samples collected at Zackenberg Research station (northeast Greenland) in August 2021 Fifty (50) sample plots were visited to collect invertebrates (using pitfalls) and sample soil, vegetation, muskox feces and wool. The sheet PlotInfo provides information on the sample plots, which were placed using a stratified random placement procedure across 5 vegetation types and the elevational gradient The sheet Soil contains trace element concentrations (ppm) as well as N and C (%) measured in the soil samples across all 50 sample plots The sheet Vegetation contains trace element concentrations (ppm) as well as N and C (%) measured in the vegetation samples across all 50 sample plots The sheet Insects contains trace element concentrations (ppm) measured in the various insect groups captured in pitfall traps in 9 sample plots The sheet Muskox feces contains trace element concentrations (ppm) measured in the feces samples collected at all 50 sample plots The sheet Muskox Wool contains trace element concentrations (ppm) measured in 25 wool samples collected throughout the sampling area (not at specific sample plots).   Trace element concentrations were measured at the ICP-MS platform at the Observatoirie Midi-Pyrenees, Toulouse, France N and C analyses were done at Department of Biology, University of Copenhagen, Denmark   For further information on the project, samples, methods used contact flbe@ecos.au.dk

Dataset from "How does a warm and low-snow winter impact the snow cover dynamics in a humid and discontinuous boreal forest? Insights from observations and modeling in eastern Canada"

The dataset presented below is described in the publication “How does a warm and low-snow winter impact the snow cover dynamics in a humid and discontinuous boreal forest? An observational study in eastern Canada.” from Bouchard et al. (submitted) in the journal Hydrology and Earth System Science. The original dataset includes monitoring data collected at Montmorency Forest (47.29°N, 71.17°W) from 15 October 2020 to 15 June 2021 (W20-21) and from 15 October 2021 to 15 June 2021 (W21-22) in a medium-size gap, the small-size gap and under the canopy. The study site is a balsam fir – whit birch stand on a 12° slope of north-east aspect. In the monitoring dataset you can find at the hourly timestep: <ul> <li>Snow depth (cm)</li> <li>Soil temperature at 20 cm, 10 cm and 5 cm below ground surface (°C)</li> <li>Soil-snow interface temperature (°C)</li> <li>Snow temperature every 15 cm from the ground surface (°C)</li> <li>Snow surface temperature (°C)</li> <li>Air temperature (°C)</li> <li>Relative humidity (%)</li> <li>Soil volumetric water content at 15 cm below the ground surface (0 – 1)</li> </ul> The dataset also includes snow pit observations taken at Montmorency Forest during W20-21 and during W21-22. Each winter, four (4) snow pits were dug inside medium-size gaps, small-size gaps and at subcanopy locations. Snow pit measurement dates are presented in Bouchard et al. (submitted). Each snow pit includes the vertical profile of: <ul> <li>Snow stratigraphy</li> <li>Snow temperature</li> <li>Snow density</li> <li>Snow specific surface area (SSA)</li> </ul>   The snow pit height corresponds to the upper boundary of the topmost snow layer in the stratigraphy profile. For density measurements, the height value corresponds to the center of the 3-cm thick box cutter. For the SSA, the value is measured optically at the top of the sample. This value is representative of the top 1 cm of the snow sample, as this is the typical e-folding depth of 1310 nm radiation in snow. Grain type codes for the snowpack stratigraphy correspond to the International Classification for Seasonal Snow (Fierz et al., 2009): <ul> <li>PP: precipitation particles </li> <li>DF: decomposed and fragmented precipitation particles</li> <li>RG: rounded grains</li> <li>FC: faceted crystals</li> <li>FCxr: rounding faceted particles</li> <li>DH: depth hoar</li> <li>MFpc: melt forms – rounded polycrystals</li> <li>MF: melt forms – clustered rounded grains</li> <li>MFcr: melt forms – melt-freeze crusts</li> <li>IF: ice formations</li> </ul>

Impact of a Single Nucleotide Change or Non-Nucleoside Modifications in G-Rich Region on the Quadruplex–Duplex Hybrid Formation

&bdquo;Impact of a Single Nucleotide Change or Non-Nucleoside Modifications in G-Rich Region on the Quadruplex–Duplex Hybrid Formation”. In article, a method to discriminate between two target RNA sequences that differ by one nucleotide only is presented. The method relies on the formation of alternative structures, i.e., quadruplex–duplex hybrid (QDH) and duplex with dangling ends (Dss), after hybridization of RNA G-rich oligonucleotides with target sequences containing 5′–GGGCUGG–3′ (UT) or 5′–GGGCGGG–3′ (GT) fragments. Using biophysical methods, the effect of covalently attached G4 ligand on the ability of G-rich oligonucleotides to assemble a G-quadruplex motif was studied. The sequence-guided o-BMVC G4-ligand acted as a quadruplex stabilizer but not duplex. The use of such conjugates (o-BMVC-RNA) creates the possibility of inducing and stabilizing the bimolecular quadruplexes on the G-rich mRNA template in a sequence-specific manner. The formation of QDH or Dss structures is dependent on a single nucleotide change in the target sequence, and the possibility to selectively stabilize the G-quadruplex domain by attaching the G4 ligand may become an attractive alternative therapy for patients with an EGFR-L858R mutation. <a href="https://www.mdpi.com/2218-273X/11/8/1236">https://www.mdpi.com/2218-273X/11/8/1236</a>, <a href="https://doi.org/10.3390/biom11081236">https://doi.org/10.3390/biom11081236</a> Files are available in original formats: .xlsx, .opi, bruker, MultiGauge raw-image file (.img), JPG file (.jpg), text document (.txt)

Fig. 4 in The complexity of sound quantification of specialized metabolite biosynthesis: The stress related impact on the alkaloid content of Catharanthus roseus

Fig. 4. The stress-related increase of the concentration of natural products. In principle, two major effects are responsible for the stress-related increase, i. e., the decrease of the reference value (e.g. dry weight), and an enhancement of biosynthetic activity. The latter one is due either to stress-related up-regulation ("active increase" of enzymatic activity) or a "passive shift" cause by the stress-related overreduction due to stomatal closure. Decreases of factors are displayed in red, the related enhancements in blue. (For interpretation of the references to colour in this figure legend, the reader is referred to the Web version of this article.)

Differentiation between young and old leaves is mentioned in the Materials and methods section. Different lower-case letters on top of the columns for each period of time (10 and 20 days) indicate significant differences (P ≤ 0.05) as calculated using the least significant difference (LSD) test; n = 8. Every period has 5 bars, and these bars from left to right are control, 100 mM, 200 mM, 300 mM, 400 mM NaCl solution, respectively. The bars display the standard deviation.
