Dose relationships can exacerbate, mute, or reverse the impact of heterospecific host density on infection prevalence
The likelihood an individual becomes infected depends on the community in which it is embedded. For environmentally transmitted parasites, host community composition can alter host density, the density of parasites that hosts encounter in the environment, and the dose to which hosts are subsequently exposed. While some multi-host theory incorporates some of these factors (e.g., competition among hosts), it does not currently consider the nonlinear relationships between parasite exposure dose and per-propagule infectivity (dose-infectivity relationships), between exposure dose and infected host mortality (dose-mortality relationships), and between exposure dose and parasite propagule excretion (dose-excretion relationships). This makes it difficult to predict the impact of host species on one another's likelihood of infection. To understand the implications of these non-linear dose relationships for multi-host communities, we first performed a meta-analysis on published dose-infectivity experiments to quantify the proportion of accelerating, linear, or decelerating dose-infectivity relationships; we found that most experiments demonstrated decelerating dose-infectivity relationships. We then explored how dose-infectivity, dose-mortality, and dose-excretion relationships might alter the impact of heterospecific host density on infectious propagule density, infection prevalence, and density of a focal host using two host, one parasite models. We found that dose relationships either decreased the magnitude of the impact of heterospecific host density on propagule density and infection prevalence via negative feedback loops (decelerating dose-infectivity relationships, positive dose-mortality relationships, and negative dose-excretion relationships), or increased the magnitude of the impact of heterospecific host density on infection prevalence via positive feedback loops (accelerating dose-infectivity relationships and positive dose-excretion relationships). Further, positive dose-mortality relationships resulted in hosts that traditionally decrease disease (e.g. low-competence, strong competitors) increasing infection prevalence, and vice versa. Finally, we found that dose-relationships can create positive feedback loops that facilitate friendly competition (i.e., increased heterospecific density has a positive effect on focal host density because the reduction in disease outweighs the negative effects of interspecific competition). This suggests that without taking dose relationships into account, we may incorrectly predict the effect of heterospecific host interactions, and thus host community composition, on environmentally transmitted parasites.

Metabolic data: Inhibition of mitochondrial complex I reverses NOTCH1-driven metabolic reprogramming in T-cell acute lymphoblastic leukemia
<p>T-cell acute lymphoblastic leukemia (T-ALL) is commonly driven by activating mutations in <em>NOTCH1 </em>that facilitate glutamine oxidation. Here we identify oxidative phosphorylation (OxPhos) as a critical pathway for leukemia cell survival and demonstrate a direct relationship between <em>NOTCH1</em>, elevated OxPhos gene expression, and acquired chemoresistance in pre-leukemic and leukemic models. Disrupting OxPhos with IACS-010759, an inhibitor of mitochondrial complex I, causes potent growth inhibition through induction of metabolic shut-down and redox imbalance in <em>NOTCH1</em>-mutated and less so in <em>NOTCH1</em>-wt T-ALL cells. Mechanistically, inhibition of OxPhos induces metabolic reprogramming into glutaminolysis. We show that pharmacological blockade of OxPhos combined with inducible knock-down of glutaminase, the key glutamine enzyme, confers synthetic lethality in mice harboring <em>NOTCH1</em>-mutated T-ALL<em>. </em>We leverage this synthetic lethal interaction to demonstrate that IACS-010759 in combination with chemotherapy containing L-asparaginase, an enzyme that uncovers the glutamine dependency of leukemic cells, causes reduced glutaminolysis and profound tumor reduction in pre-clinical models of human T-ALL. In summary, this metabolic dependency of T-ALL on OxPhos provides a rational therapeutic target.</p>

Data from: Meteorological Controls on Reversible Resonance Changes in Natural Rock Arches
<p>Meteorological data collected at rock arch sites concurrently with ambient seismic data (hosted separately by the IRIS Data Management Center, <a href="https://doi.org/10.7914/SN/5P_2013">https://doi.org/10.7914/SN/5P_2013</a>). All sites, except Aqueduct Arch, consist of temperature data (air and rock) recorded at 1- or 5-min intervals by portable HOBO U23 Pro v2 sensors, with measurements lasting from 10 hours to 96 hours and trimmed to match the time window of the seismic data.</p> <p>Air temperature was recorded by mounting the sensor in nearby vegetation to keep the sensor above the ground surface. Rock temperature was recorded on two separate sensors, which were placed against the bedrock surface and covered by a rock to provide shading and coupling. Analysis performed using rock temperature used the average of the two sensors. Several sites lack air temperature data.<br> <br> At Aqueduct Arch, a solar-powered HOBONet weather station recorded data from February 2017 - May 2018 at 15-minute intervals. The recorded quantities were: air temperature, rock temperature (recorded via a sensor embedded 2 cm into the bedrock), wind speed and direction, relative humidity, and precipitation.</p>

Data from: Electrodeposition of iron from 1-ethyl-3-methylimmidazolium trifluoromethanesulphonate and reverse microemulsions of Triton X-100
<p>Electrodeposition of iron (Fe) was investigated in three different media: namely, a hydrophilic ionic liquid (IL), 1-ethyl-3-methylimmidazolium trifluoromethanesulphonate, conventional reverse microemulsion (RME)/reverse micellar solution, and IL based reverse microemulsion of a non-ionic surfactant, Triton X-100 with a view to achieving control over size, shape, and morphology of the electrodeposited iron. Electrochemical behavior of Fe<sup>2+ </sup>was studied using cyclic voltammetric technique with a copper electrode as the working electrode. Electrochemical reduction of Fe<sup>2+</sup> in all the studied media was found to be an electrochemically irreversible, diffusion-controlled process. Successful potentiostatic electrodeposition of metallic iron was performed in all the studied media on copper substrate using bulk electrolysis method. The obtained iron electrodeposits were characterized using a scanning electron microscope (SEM) and an x-ray diffractometer (XRD). The controlled diffusion of Fe<sup>2+</sup> towards electrode surface<sup> </sup>in all the media resulted in the formation of nanoparticles of iron, but compact layers of granular nanoparticles could be achieved from both the conventional and IL based RME systems. The IL based microemulsions synergistically combined the advantageous features of both the IL and RME and showed the prospect of tuning the size, shape, and morphology of the electrodeposited iron.</p>

Reversing the decline of threatened koala (Phascolarctos cinereus) populations in New South Wales: Using genomics to enhance conservation outcomes
<p>Genetic management is a critical component of threatened species conservation. Understanding spatial patterns of genetic diversity is essential for evaluating the resilience of fragmented populations to accelerating anthropogenic threats. Nowhere is this more relevant than on the Australian continent, which is experiencing an ongoing loss of biodiversity that exceeds any other developed nation. Using a proprietary genome complexity reduction-based method (DArTSeq), we generated a data set of 3,239 high quality Single Nucleotide Polymorphisms (SNPs) to investigate spatial patterns and indices of genetic diversity in the koala (<em>Phascolarctos cinereus</em>), a highly specialised folivorous marsupial that is experiencing rapid and widespread population declines across much of its former range.<strong> </strong>Our findings demonstrate that current management divisions across the state of New South Wales (NSW) do not fully represent the distribution of genetic diversity among extant koala populations, and that care must be taken to ensure that translocation paradigms based on these frameworks do not inadvertently restrict gene flow between populations and regions that were historically interconnected. We also recommend that koala populations should be prioritised for conservation action based on the scale and severity of the threatening processes that they are currently faced with, rather than placing too much emphasis on their perceived value (e.g., as reservoirs of potentially adaptive alleles), as our data indicate that existing genetic variation in koalas is primarily partitioned amongst individual animals. As such, the extirpation of koalas from any part of their range represents a potentially critical reduction of genetic diversity for this iconic Australian species.</p>
