Fate of organic solvent-soluble extractives and arabinogalactan during brown rot degradation of Siberian larch heartwood
<p>This dataset contains measurement data from the following publication: Belt, T.; Harju, A.; Venäläinen, M.; Kilpeläinen, P. (2024) Fate of organic solvent-soluble extractives and arabinogalactan during brown rot degradation of Siberian larch heartwood. European Journal of Wood and Wood Products. DOI: 10.1007/s00107-024-02146-3. The data consist of mass loss and extractive content data for samples derived from two different decay tests. The decay tests and measurement procedures are described in brief below; further details can be found in the publication.</p> <p>Decay test 1 was a stacked-sample test. Sample blocks were prepared from fresh Siberian larch heartwood and Scots pine sapwood. The decay test was conducted in test tubes over nutrient agar inoculated with <em>Coniophora puteana</em> or <em>Rhodonia placenta</em>. Each tube (N =5) received 7 heartwood or sapwood blocks stacked on top of each other (sample positions 1-7 from top to bottom). After decay, the mass losses of all larch heartwood and pine sapwood samples were measured. The decayed larch heartwood samples were individually ground to powder and extracted with methanol to obtain organic solvent-soluble extractives and with cold water to obtain arabinogalactan.</p> <p>Decay test 2 was a time-series test. Increment cores were obtained from 5 Siberian larch trees, with 8 cores obtained from each tree. Core pieces were cut from outer heartwood and split lengthwise to produce two halves: one half for the decay test and the other to act as an undecayed extractive content control. The decay test was conducted on petri dishes containing nutrient agar inoculated with <em>C. puteana</em> or <em>R. placenta</em>. One core half from each tree exposed to <em>C. puteana</em> and one exposed to <em>R. placenta</em> were removed from the decay test after 10, 20, 27 and 36 days of incubation. After decay, the mass losses of all decay test core halves were measured. The decay test and control core halves were individually ground to powder and extracted with methanol to obtain organic solvent-soluble extractives and with cold water to obtain arabinogalactan.</p> <p>Organic solvent-soluble extractives in the methanol extracts were analysed by GC-MS after trimethyl silylation of the extracts. A total of 13 extractive compounds were identified and quantified in the extracts: 5 fatty acids (palmitic, linolenic, linoleic, oleic, and stearic acid), 6 resin acids (isopimaric, pimaric, palustric, dehydroabietic, abietic, and neoabietic acid), and 2 flavonoids (dihydrokaempferol and taxifolin). Arabinogalactan in the cold water extract was analysed by GC-FID after acid methanolysis. Arabinogalactan was determined as the sum of arabinose and galactose obtained by methanolysis.</p> <p>The “Decay test 1.csv”-file gives the sample identifiers (ID, sample type, test fungus, tube number, sample position), and mass losses of the larch heartwood and pine sapwood samples, and the extractive contents of the larch heartwood samples. Extractive content data are given for all fatty acids, resin acids, and flavonoids quantified in the methanol extracts, and for arabinose and galactose quantified in the cold water extracts. Extractive contents are given on a decayed wood basis (mg/g decayed wood).</p> <p>The “Decay test 2.csv”-file gives the sample identifiers (ID, sample type, test fungus, tree number, core number, decay test time), mass losses, and extractive contents of the decayed and control larch heartwood core halves. Extractive content data are given for all fatty acids, resin acids, and flavonoids quantified in the methanol extracts, and for arabinose and galactose quantified in the cold water extracts. Extractive contents are given on a decayed wood basis (mg/g decayed wood).</p>

Identification of the regulatory circuit governing corneal epithelial fate determination and disease trackhub and additional data
<p>The transparent corneal epithelium in the eye is maintained through the homeostasis regulated by limbal stem cells, while the non-transparent epidermis relies on epidermal keratinocytes for renewal. Despite their cellular similarities, the precise cell fates of these two types of epithelial stem cells, which give rise to functionally distinct epithelia, remain unknown. We performed a multi-omics analysis of human limbal stem cells from the cornea and keratinocytes from the epidermis, and characterized their molecular signatures, highlighting their similarities and differences. Through gene regulatory network analyses, we identified shared and cell type-specific transcription factors that define specific cell fates, and established their regulatory hierarchy. Single-cell RNA-seq analyses of the cornea and the epidermis confirmed these shared and cell type-specific transcription factors. Notably, the shared and limbal stem cell-specific transcription factors can cooperatively target genes associated with corneal opacity. Importantly, we discovered that <em>FOSL2</em>, a direct PAX6 target gene, is a novel candidate associated with corneal opacity, and it regulates genes implicated in corneal diseases. By characterizing molecular signatures, our study unveils the regulatory circuitry governing the limbal stem cell fate and its association with corneal opacity.</p> <p> </p> <p>Files present are within the UCSC trackhub format containing bigwig and bignarrowpeak files associated with the publication:</p> <p>Multi-omics analyses identify transcription factor interplay in corneal epithelial fate determination and disease</p> <p>doi: https://doi.org/10.1101/2022.07.13.499857</p> <p> </p>

Environmental fate of combustion-derived organic compounds in arid, urban soils in central Arizona-Phoenix
In this research we wanted to ask, what is the magnitude, distribution, and fate of non-point carbon pollution in a low-density, urban area? To answer this question, the goal of the project is to: 1) characterize and quantify combustion-derived carbon compounds in soils near roadways across the Phoenix valley, 2) explore the dynamic fate of Polycyclic Aromatic Hydrocarbons (PAHs) in soils, and 3) assess the importance of microbial community structure in PAH storage and dynamics. We collected 63 soil samples near highways across the Phoenix valley to characterize and quantify PAH compounds using extraction methods with Ultrasound Sonication and analyses by Gas Chromatography-Mass Spectrometry (GC-MS). Additionally, we measured a suite of soil properties and processes to explore the role of abiotic and biotic factors on the retention of PAHs in urban soil. PAH concentrations in arid Phoenix soils ranged from 52 ug/kg dry soil to 8,296 ug/kg (mean 926 ug/kg), nearly an order of magnitude lower on average than expected based on data from other cities (Figure 1, Table 1). The project findings show the extent of these pollutants, an EPA-priority group of hazardous compounds, in urban soils. Although the most likely sources for PAH content in roadway soils are vehicle emissions, they were not correlated with traffic density (r2 = 0.024; p = 0.26) or highway age (r2 = 0.044; p = 0.13) across all sites. However, PAH concentrations were significantly correlated to soil organic matter (r2 = 0.36; p less than 0.001). These results suggest that PAH concentrations in roadway soils of desert cities may be controlled by factors associated with carbon retention, such as soil organic matter, rather than source or rate of deposition

Supplementary material from "Possible fates of the dispersion of SARS-COV-2 in the Mexican context"
<p>The determination of the adequate time for house confinement and when social distancing restrictions should end are now two of the main challenges that any country has to face in an effective battle against. The possibility of a new outbreak of the pandemic and how to avoid it is, nowadays, one of the primary objectives of epidemiological research. In this work, we go deep in this subject by presenting an innovative compartmental model, that explicitly introduces the number of active cases, and employing it as a conceptual tool to explore the possible fates of the dispersion of SARS-COV-2 in the Mexican context. We incorporated the impact of starting, inattention, and end of restrictive social policies on the time evolution of the pandemics via time-in-run corrections to the infection rates. The magnitude and impact on the epidemic due to post-social restrictive policies are also studied. The scenarios generated by the model can help authorities to determine an adequate time and population load that may be allowed to reassume normal activities.</p>
Data from: Victims of ancient hyperthermal events herald the fates of marine clades and traits under global warming
<p>Organismic groups vary non-randomly in their vulnerability to extinction. However, it is unclear whether the same groups are consistently vulnerable, regardless of the dominant extinction drivers, or whether certain drivers have their own distinctive and predictable victims. Given the challenges presented by anthropogenic global warming, we focus on changes in extinction selectivity trends during ancient hyperthermal events: geologically rapid episodes of global warming. Focusing on the fossil record of the last 300 million years, we identify clades and traits of marine ectotherms that were more prone to extinction under the onset of six hyperthermal events than during other times. Hyperthermals enhanced the vulnerability of marine fauna that host photosymbionts, particularly zooxanthellate corals, the reef environments they provide, and genera with actively burrowing or swimming adult life-stages. The extinction risk of larger-sized fauna also increased relative to non-hyperthermal times, while genera with a poorly buffered internal physiology did not become more vulnerable on average during hyperthermals. Hyperthermal-vulnerable clades include rhynchonelliform brachiopods and bony fish, whereas resistant clades include cartilaginous fishes, and ostreid and venerid bivalves. These extinction responses in the geological past mirror modern responses of these groups to warming, including range shift magnitudes, population losses, and experimental performance under climate-related stressors. Accordingly, extinction mechanisms distinctive to rapid global warming may be indicated, including sensitivity to warming-induced seawater deoxygenation. In anticipation of modern warming-driven marine extinctions, the trends illustrated in the fossil record offer an expedient preview.</p>
Inferring individual fate from aquatic acoustic telemetry data
<ol> <li>Acoustic telemetry has become a popular means of obtaining individual behavioural data from a wide array of species in marine and freshwater systems. Fate information is crucial to understand important aspects of population dynamics such as mortality, predation or dispersal rates.</li> <li>Here we present a method to infer individual fate from acoustic telemetry arrays of receivers with overlapping detection ranges. Our method depends exclusively on information on animal movements and the characteristics and configuration of the telemetry equipment. By answering a limited number of simple questions, our method identifies six different fates: tagging mortality, natural mortality, fishing mortality, predation, dispersal and survival.</li> <li>Applying the method to a cod telemetry dataset, we were able to determine fate for 97% of the individuals. We validate the results using several external sources of information, such as recaptures from fishers and control fish with known fate.</li> <li>The method is readily applicable to a wide array of species with minimal adjustments, expanding the range of hypotheses that can be tested using telemetry data.</li> </ol>
Data from: Entangled fates of holobiont genomes during invasion: nested bacterial and host diversities in Caulerpa taxifolia
Successful prevention and mitigation of biological invasions requires retracing the initial steps of introduction, as well as understanding key elements enhancing the adaptability of invasive species. We studied the genetic diversity of the green alga Caulerpa taxifolia and its associated bacterial communities in several areas around the world. The striking congruence of α and ß diversity of the algal genome and endophytic communities reveals a tight association, supporting the holobiont concept as best describing the unit of spreading and invasion. Both genomic compartments support the hypotheses of a unique accidental introduction in the Mediterranean and of multiple invasion events in Southern Australia. In addition to helping with tracing the origin of invasion, bacterial communities exhibit metabolic functions that can potentially enhance adaptability and competitiveness of the consortium they form with their host. We thus hypothesize that low genetic diversities of both host and symbiont communities may contribute to the recent regression in the Mediterranean, in contrast with the persistence of highly diverse assemblages in southern Australia. This study supports the importance of scaling up from the host to the holobiont for a comprehensive understanding of invasions.
