title: Data on Selective adsorption of terrestrial dissolved organic matter to inorganic surfaces along a boreal inland water continuum
title: Data on Selective adsorption of terrestrial dissolved organic matter to inorganic surfaces along a boreal inland water continuum

description: Different processes contribute to the loss or transformation of dissolved organic matter (DOM) and change DOM concentration and composition systematically along the inland water continuum. Substantial efforts have been made to estimate the importance of microbial and photochemical degradation for DOM concentration and composition and, to some extent, also DOM losses by flocculation, whereas the significance of DOM adsorption to inorganic surfaces has received less attention. Hence, knowledge on the possible extent of adsorption, its effect on DOM loads and composition and on where along the aquatic continuum it might be important is currently limited or lacking altogether. Here, we experimentally determine DOM adsorption onto mineral particles in freshwater ecosystems covering a water residence time gradient in boreal landscape Sweden. We hypothesized that adsorption would gradually decrease with increasing water residence time, but actually found that DOM is highly susceptible to adsorption throughout the aquatic continuum. Mass spectrometry and fluorescence analysis on DOM suggest that freshly produced aquatic DOM is less susceptible to adsorption than more terrestrial material. Moreover, the percentage DOM adsorbed in the experiments greatly exceeds the actual adsorption taking place in boreal inland waters across all studied systems. These results illustrate the potential impact of mineral erosion, for example as a result of agriculture, mining or forestry practices, on the availability, transport and composition of organic carbon in inland waters.

We collected water samples from 30 sites distributed throughout Sweden and studied the effect of adsorption to mineral particles on dissolved organic matter composition. The data set belongs to a manuscript accepted by the Journal of Geophysical Research - Biogeosciences.

The data set contains fluorescence and mass spectrometry data from all 30 sites before and after adsorption:
- corrected EEMs of 180 samples (30 samples, triplicates, before and after adsorption treatment)
- PARAFAC model of the 180 EEMs
- compiled mass spectrometry data (30 samples, before and after adsorption treatment)

title: Code and Data for “Classification of Medieval Documents: Determining the Issuer, Place of Issue, and Decade for Old Swedish Charters”
title: Code and Data for “Classification of Medieval Documents: Determining the Issuer, Place of Issue, and Decade for Old Swedish Charters”

description: Code and data for the article Classification of Medieval Documents: Determining the Issuer, Place of Issue, and Decade for Old Swedish Charters (to appear in DHN2020 Digital Humanities in the Nordic Countries}, Riga, 17--20 March 2020).
The zip-file contains Python code, an XML data file, and a pdf document.

The study based on this code and dataset is a comparative exploration of different classification tasks for Swedish medieval charters (transcriptions from the SDHK collection) and different classifier setups. In particular, we explore the identification of the issuer, place of issue, and decade of production. The experiments used features based on lowercased words and character 3- and 4-grams. We evaluated the performance of two learning algorithms: linear discriminant analysis and decision trees. For evaluation, five-fold cross-validation was performed. We report accuracy and macro-averaged F1 score. The validation made use of six labeled subsets of SDHK combining the three tasks with Old Swedish and Latin. Issuer identification for the Latin dataset (595 charters from 12 issuers) reached the highest scores, above 0.9, for the decision tree classifier using word features. The best corresponding accuracy for Old Swedish was 0.81. Place and decade identification produced lower performance scores for both languages. Which classifier design is the best one seems to depend on peculiarities of the dataset and the classification task. The present study does however support the idea that text classification is useful also for medieval documents characterized by extreme spelling variation.

title: Supplementary data for "CRISPR-Cas9 induces large structural variants at on-target and off-target sites in vivo"

description: CRISPR-Cas9 genome editing has potential to cure diseases without current treatments, but therapies must be safe. Here we show that CRISPR-Cas9 editing can introduce unintended mutations in vivo, which are passed on to the next generation. By editing fertilized zebrafish eggs using four guide RNAs selected for off-target activity in vitro, followed by long-read sequencing of DNA from &gt;1100 larvae, juvenile and adult fish across two generations, we find that structural variants (SVs), i.e., insertions and deletions ≥50 bp, represent 6% of editing outcomes in founder larvae. These SVs occur both at on-target and off-target sites. Our results also illustrate that adult founder zebrafish are mosaic in their germ cells, and that 26% of their offspring carries an off-target mutation and 9% an SV. Hence, pre-testing for off-target activity and SVs using patient material is advisable in clinical applications, to reduce the risk of unanticipated effects with potentially large implications.

title: Supplementary data for the article "funMotifs: Tissue-specific transcription factor motifs"

description: We built a framework to identify tissue-specific functional motifs (funMotifs) across the genome based on thousands of annotation tracks obtained from large-scale genomics projects including ENCODE, RoadMap Epigenomics and FANTOM. The annotations were weighted using a logistic regression model trained on regulatory elements obtained from massively parallel reporter assays. Overall, genome-wide predicted motifs of 519 TFs were characterized across fifteen tissue types. funMotifs summarizes the weighted annotations into a functional activity score for each of the predicted motifs.

title: Data on the impact of volcanism on Scandinavian climate and human societies during the Holocene: Insights into the Fimbulwinter eruptions (536/540 AD)

description: Recent paleoclimatic research has revealed that volcanic events around 536–540 AD caused severe, short-term global cooling. For this same period, archeological research from various regions evidences significant cultural transformation. 

This study focused on the effects of the 536/540 AD volcanic event in four Scandinavian regions by exploring the shift in demographic and land use intensity before, during, and after this abrupt climate cooling. To achieve this, we performed climate simulations with and without volcanic eruptions using a dynamically downscaled climate model (iLOVECLIM) at a high resolution (0.25° or ~25 km). We integrated the findings with a comprehensive collection of radiocarbon dates from excavated archeological sites across various Scandinavian regions. Our Earth System Model simulates pronounced cooling (maximum ensemble mean −1.1°C), an abrupt reduction in precipitation, and a particularly acute drop in growing degree days (GDD0) after the volcanic event, which can be used to infer likely impacts on agricultural productivity. When compared to the archeological record, we see considerable regional diversity in the societal response to this sudden environmental event. As a result, this study provides a more comprehensive insight into the demographic chronology of Scandinavia and a deeper understanding of the land-use practices its societies depended on during the 536/540 AD event.

title: Data on how repeated disturbances affect microbial ecosystem resistance in natural lake bacterioplankton communities
title: Data on how repeated disturbances affect microbial ecosystem resistance in natural lake bacterioplankton communities

description: Data associated with the manuscript "Disturbance history can increase functional stability in the face of both repeated disturbances of the same type and new disturbances" by Renes et al. 2020.

Climate change is expected to increase the incidences of extremes in environmental conditions. To investigate how repeated disturbances affect microbial ecosystem resistance, natural lake bacterioplankton communities were subjected to repeated temperature disturbances of two intensities (25 °C and 35 °C), and subsequently to an acidification event. We measured functional parameters (bacterial production, abundance, extracellular enzyme activities) and community composition parameters (richness, evenness, niche width) and found that, compared to undisturbed control communities, the 35 °C treatment was strongly affected in all parameters, while the 25 °C treatment did not significantly differ from the control. Interestingly, exposure to multiple temperature disturbances caused gradually increasing stability in the 35 °C treatment in some parameters, while others parameters showed the opposite, indicating that the choice of parameters can strongly affect the outcome of a study. The acidification event did not lead to stronger changes in community structure, but functional resistance of bacterial production towards acidification in the 35 °C treatments increased. This indicates that functional resistance in response to a novel disturbance can be increased by previous exposure to another disturbance, suggesting similarity in stress tolerance mechanisms for both disturbances. These results highlight the need for understanding function- and disturbance-specific responses, since general responses are likely to be unpredictable.

title: Halo-fenomen observerade i Uppsalatrakten från 1974 till 1976

description: The described halo phenomena or halo components were observed during an unbroken period of 8 years. Only a small number of the observations were made in other parts of the country.

These observations are not only of interest for meteorologists but even for persons interested in optical events in the atmosphere. Worth to mention here are photographers and people interested in nature. The experience of a brilliant and comprehensive halo phenomena is something one will never forget! Most prominent are special optical events such as multiple halo or mirage. I here refer to August 21, 1974, a halo display with seven components.

I strongly recommend the following scientific article describing the types of well formed ice crystals necessary to create the observed halo components. The author of the article was one of my teachers at Uppsala University:

Upplevelsen av ett briljant och omfattande halofenomen är någonting man aldrig kommer att glömma! Mest framträdande är speciella optiska företeelser som multipla halon eller hägringar. Jag hänvisar här till 21 augusti 1974, ett halo-skådespel med sju halo-komponenter.
