Data for: Human activity coupled with climate change strengthens the role of lakes as an active pipe of dissolved organic matter

This dataset contains data from an investigation to resolve the relative importance of multiple environmental drivers on the quantity and quality of chromophoric DOM in lakes at the continental scales. The study is described in the paper: "Du Y., Chen F., Zhang Y., He H., Wen S., Huang X., Song C., Li. K., Wang J., Kellings D., and Lu Y. 2023. Human activity coupled with climate change strengthens the role of lakes as an active pipe of dissolved organic matter, Earth's Future, in press". The primary objectives of the study were to (i) quantity the magnitude of environmental drivers modulating lacustrine DOM quantity and quality at a continental scale, including climate, land cover, societal development, and water retention time, and (ii) unravel individual and interactive effects of the environmental drivers. Firstly, we constructed a structural equation model framework that incorporated both direct and indirect pathways. Secondly, we collected a continental-scale dataset of lake DOM quantity and quality, along with the corresponding environmental driver variables from a group of carefully selected lakes (n=182). Lastly, we established structure equation models to analyze DOM quantity and quality variations as a function of the four environmental drivers. The main results include: (1) land cover and societal development both exhibit positive direct effects on lake CDOM quantity, highlighting the significant role of well-vegetated soils and anthropogenic activities as sources of lake DOM on a continental scale. (2) Climate has two strong but opposite effects –a warming and wet climate facilitates soil OM production and export but also enhances CDOM in-lake transformation. (3) Three proxies are proposed as indicators of the magnitude of biogeochemical drivers influencing lake DOM across ecoclimatic zones, including fluorescent DOM/DOC indicating economic activity, percentages of a degraded fluorescent DOM component indicating solar irradiation, and percent tyrosine-like DOM reflecting DOM processing time within the watershed and lake.

Water loss, not overheating, limits the activity period of an endothermic Sonoran Desert bee

<ol> <li>Desert animals must manage the physiological stresses of heat and desiccation; evaporative heat loss mitigates overheating but exacerbates water stress. Small endothermic flying insects may be particularly vulnerable to overheating and water stress as a result of high surface area to volume ratios, but we lack quantitative understanding of the relative magnitude of these abiotic stressors in flying desert invertebrates, despite their ecological importance.</li> <li>During the hottest and driest weeks of the year, many thousands of males of the Sonoran Desert digger bee (Centris caesalpiniae) flew near-continuously at elevated thorax temperatures for hours at mating aggregation sites, while occasionally fighting other males and digging for females.</li> <li>To determine whether incapacitating high temperatures or water loss limited the activity period of male C. caesalpiniae, we assessed wet and dry body mass and water content through the activity period, crop volume and sugar content, microclimate selection, water loss rate and metabolic water production during flight, critical water content, and maximum critical temperature.</li> <li>Body masses and sizes of males declined through the morning and smaller bees had higher fractional water contents. Crop volume and sugar content did not vary through the day or with bee size.</li> <li>Maximum critical temperature during flight was 51°C, similar to those measured for other bees, and well above temperatures reached in the field, suggesting that avoidance of over-heating does not limit activity in this desert bee.</li> <li>The critical water content of Centris bees averaged 50%. Measures of net water loss rate indicated that males approached lethal water loss limits within four hours, suggesting that desiccation tolerance limits activity. Remarkably, male C. caesalpiniae were not observed to forage at floral or water sources during the activity period, and foraged over multiple days, suggesting selection to maintain reproductive success and that these males have a mechanism to rehydrate when not at the mating aggregation.</li> </ol>

Green Synthesis of Zinc Oxide (ZnO) Nanoparticles Using Aqueous Extract of Shilajit: Their Characterization and Anticancer Activity

UV analysis of aqueous extract of shilajit and zinc oxide nanoparticles (ZnO NPs) of shilajit extract showed the absorbance peaks at 422.40 nm and 357.90 nm. The abosrbance peaks confirms the presence of ZnO NPs in the reaction mixture. The FTIR spectrum of shilajit extract and ZnO NPs of shilajith extract showed the strong broad absorbance at 3428 cm−1 are due to the stretching vibration of hydroxyl (OH) functional groups. The absorption band at 1633 cm-1 corresponded the stretching vibration of N-H groups. The peak at 1414 cm-1 observed in the spectrum indicate the presence of mono-substituted alkynes. The peak at 1163 cm-1 showed the presence of C-O bonds. The XRD pattern of ZnO NPs of shilajith extract, characterized by their high intensity, were observed at specific 2θ peak values, namely 31.69°, 34.33°, 36.17°, 47.45°, 56.52°, 62.77°, 67.87° and 68.99°, and can be attributed to the lattice planes (100), (002), (101), (102), (110), (103), (112), and (201), respectively. The particle size of ZnO NPs of shilajit extract was measured to be 348 nm and the polydispersity index was found to be 0.322.

Data from: Microbial activity contributes to spatial heterogeneity of wetland methane fluxes

The emission of methane from wetlands is spatially heterogeneous, as concurrently measured surface fluxes can vary by orders of magnitude within the span of a few meters. Despite extensive study and the climatic significance of these greenhouse gas emissions, it remains unclear what drives these large within-site variations, creating a knowledge-gap that impedes a mechanistic understanding of wetland fluxes. While geophysical variables including water table depth (WTD) and soil temperature are known to correlate with CH4 flux, measurable variance in these parameters declines as spatial and temporal scales become finer. Here, we leveraged depth-stratified gene abundance and gene expression measurements of methanogenesis and methanotrophy to investigate CH4 flux variance at an ombrotrophic peat bog. Our results show that the flux variance was strongly correlated to methanogen abundance and that peat depth also exerted significant control over CH4 flux, methanogen abundance, and the relationship between the two. Correlations between CH4 flux and either WTD or soil temperature were absent or minimal. These findings suggest that microbial factors likely underlie localized variance in wetland CH4 flux, and that a greater reliance on biological predictors could improve our ability to understand wetland methane fluxes at finer scales than is currently possible.

This dataset was a part of the  IJCAI 2023 competition : CC6: IntEr-HRI: Intrinsic Error Evaluation during Human-Robot Interaction (<a href="https://ijcai-23.org/competitions/">IJCAI'23 Official Website</a>). This dataset repository is divided into 3 versions: <ul> <li>Version 1: Training data + Metadata</li> <li>Version 2: Test data</li> <li>Version 3: Complete dataset (EEG + EMG) </li> </ul> For more detailed information about the competition, please visit our <a href="http://ijcai-23.dfki-bremen.de/competitions/inter-hri/">competition webpage</a>. This dataset contains recordings of the electroencephalogram (EEG) data from eight subjects who were assisted in moving their right arm by an active orthosis.  The orthosis-supported movements were elbow joint movements, i.e., flexion and extension of the right arm. While the orthosis was actively moving the subject's arm, some errors were deliberately introduced for a short duration of time. During this time, the orthosis moved in the opposite direction. The errors are very simple and easy to detect. EEG and EMG data are provided. The recorded EEG data follows the BrainVision Core Data Format 1.0, consisting of a binary data file (.eeg), a header file (.vhdr), and a marker file (.vmrk) (<a href="https://www.brainproducts.com/support-resources/brainvision-core-data-format-1-0/%7D%7D.">https://www.brainproducts.com/support-resources/brainvision-core-data-format-1-0/).</a> For ease of use, the data can be exported into the widely adopted BIDS format. Furthermore, for data analysis, processing, and classification, two popular options are available - MNE (Python) and EEGLAB (MATLAB).  If you use our dataset, cite our paper.

Bacterial mediated green synthesis of silver nanoparticles and their antibacterial and antifungal activities against drug-resistant pathogens

In the healthcare sector, the production of bioactive silver nanoparticles (AgNPs) with antimicrobial properties is of great importance. In this study, a novel bacterial strain, Paenibacillus sp. MAHUQ-63, was identified as a potential candidate for facile and rapid biosynthesis of AgNPs. The synthesized AgNPs were used to control the growth of human pathogens, Salmonella Enteritidis and Candida albicans. The bacterial culture supernatant was utilized to synthesize the nanoparticles. FE-TEM examination showed spherical-shaped nanoparticles with 15 to 55 nm in size. FTIR analysis identified various functional groups. The synthesized AgNPs demonstrated remarkable activity against S. Enteritidis and C. albicans. The zone of inhibition (ZOI) for 100 µL (0.5 mg/mL) of AgNPs against S. Enteritidis and Candida albicans were 18.0 ± 1.0 and 19.5 ± 1.3 mm, respectively. The minimum inhibitory concentrations (MICs) were 25.0 and 12.5 μg/mL against S. Enteritidis and Candida albicans, respectively. Additionally, the minimum bactericidal concentrations (MBC) were 25.0 μg/mL against both pathogenic microbes. The FE-SEM analysis showed that the treatment of AgNPs caused morphological and structural damage to both S. Enteritidis and Candida albicans. Therefore, these AgNPs can be used as a new and effective antimicrobial agent.
