Database of initial survival of three pine species after antitranspirant application
<p>Raw data from the Revista Mexicana de Ciencias Forestales paper: "Initial survival of three pine species after antitranspirant application" Revista Mexicana de Ciencias Forestales <strong>2022</strong> 13(69): 176-199. doi:<a href="http://dx.doi.org/10.3390/f9020071">10.29298/rmcf.v13i69.1145.</a></p> <p>The database corresponds to seedlings of three Mexican pines: <em>P. cooperi, P. durangensis</em> and <em>P. engelmannii</em>, that were treated with three antitranspirant products (Vapor Gard, Fitoglass, and Ecofilm) and two application methods (spraying and immersion). Survival data and root neck diameter were measured.</p>
Population-level variation in parasite resistance due to differences in immune initiation and rate of response
<p>Closely related populations often differ in resistance to a given parasite, as measured by infection success or failure. Yet, the immunological mechanisms of these evolved differences are rarely specified. Does resistance evolve via changes to the host's ability to recognize that an infection exists, actuate an effective immune response, or attenuate that response? We tested whether each of these phases of the host response contributed to threespine sticklebacks' recently evolved resistance to their tapeworm <i>Schistocephalus solidus. </i>While marine stickleback and some susceptible lake fish permit fast-growing tapeworms, other lake populations are resistant and suppress tapeworm growth via a fibrosis response. We subjected lab-raised fish from three populations (susceptible marine 'ancestors', a susceptible lake population, a resistant lake population), to a novel immune challenge using an injection of: 1) a saline control, 2) alum, a generalized pro-inflammatory adjuvant that causes fibrosis, 3) a tapeworm protein extract, or 4) a combination of alum and tapeworm protein). With enough time, all three populations generated a robust fibrosis response to the alum treatments. Yet, only the resistant population exhibited a fibrosis response to the tapeworm protein alone. Thus, these populations differed in their ability to respond to the tapeworm protein but shared an intact fibrosis pathway. The resistant population also initiated fibrosis faster in response to alum, and was able to attenuate fibrosis, unlike the susceptible populations' slow but longer-lasting response to alum. As fibrosis has pathological side-effects that reduce fecundity, the faster recovery by the resistant population may reflect an adaptation to mitigate the costs of immunity. Broadly, our results confirm that parasite detection and immune initiation, activation speed, and immune attenuation simultaneously contribute to the evolution of parasite resistance and adaptations to infection in natural populations.</p>

NREM sleep EEG and wake ERP summary: The first wave of the Global Research Initiative on the neurophysiology of schizophrenia (GRINS)
<p>Motivated by the potential of objective neurophysiological markers to index thalamocortical function in patients with severe psychiatric illnesses, we comprehensively characterized key NREM sleep parameters across multiple domains, their interdependencies, and their relationship to waking event-related potentials and symptom severity. In 72 schizophrenia (SCZ) patients and 58 controls, we confirmed a marked reduction in sleep spindle density in SCZ and extended these findings to show that fast and slow spindle properties were largely uncorrelated. We also describe a novel measure of slow oscillation and spindle interaction that was attenuated in SCZ. The main sleep findings were replicated in a demographically distinct sample, and a joint model, based on multiple NREM components, statistically predicted disease status in the replication cohort. Although also altered in patients, auditory event-related potentials elicited during wake were unrelated to NREM metrics. Consistent with a growing literature implicating thalamocortical dysfunction in SCZ, our characterization identifies independent NREM and wake EEG biomarkers that may index distinct aspects of SCZ pathophysiology and point to multiple neural mechanisms underlying disease heterogeneity. This study lays the groundwork for evaluating these neurophysiological markers, individually or in combination, to guide efforts at treatment and prevention as well as identifying individuals most likely to benefit from specific interventions.</p>

The initiation and growth of transpressional shear zones through continental arc lithosphere, southwest New Zealand
<p class="Abstract">Structural analyses combined with new U-Pb zircon and titanite geochronology show how two Early Cretaceous transpressional shear zones initiated and grew through a nearly complete section of continental arc crust during oblique convergence. Both shear zones reactivated Carboniferous faults that penetrated the upper mantle below Zealandia's Median Batholith but show opposite growth patterns and dissimilar relationships with respect to arc magmatism. The Grebe-Indecision Creek shear zone was magma-starved and first reactivated at ~136 Ma as an oblique-reverse fault, along which an outboard batholith partially subducted beneath Gondwana. This system nucleated at or above ~20 km depth and propagated downward at 2-3 mm yr<sup>-1</sup>, accumulating at least 35-45 km of horizontal (arc-normal) shortening by ~124 Ma. In contrast, the magma-rich George Sound shear zone first reactivated in the lower crust (~55 km depth) at ~124 Ma and grew upward at ~3 mm yr<sup>-1</sup>, reaching the upper crust by ~110 Ma. In this latter system, magmatism influenced shear zone architecture and drove its growth while subduction and oblique convergence ended. As magma entered the roots of the system and began to solidify, deformation was driven out of the lower crust and into the middle crust where the system widened by a factor of three when fold-thrust belts formed on either side of a steep, central transpressional shear zone. This study illustrates how the reactivation of inherited structural weaknesses localizes deformation at all depths in the lithosphere and shows how magma-deformation feedbacks influence shear zone connectivity and built a batholith from the bottom up.</p>

EXTREMA: Ballistic capture sets at Mars with initial epoch December 9, 2023
<p>EXTREMA (short for Engineering Extremely Rare Events in Astrodynamics for Deep-Space Missions in Autonomy) enables self-driving spacecraft, challenging the current paradigm under which spacecraft are piloted in the interplanetary space. Deep-space guidance, navigation, and control applied in a complex scenario is the subject of EXTREMA, which wants to engineer ballistic capture in a totally autonomous fashion. EXTREMA is erected on three pillars. Pillar 1 is on autonomous navigation. Pillar 2 involves autonomous guidance and control. Pillar 3 deals with autonomous ballistic capture, the focus of this work. The project has been awarded a European Research Council (ERC) Consolidator Grant in 2019.</p> <p>In Pillar 3 it is investigated how a spacecraft can attain ballistic capture in autonomy. Ballistic capture is an event that occurs in extremely-rare occasions, and requires acquiring a proper state (position, velocity) far away from the target planet [1]. Massive numerical simulations are required to find the specific conditions that support capture [2]. On average, 1 out of 10,000 conditions explored by the algorithm grants capture [3]. The union of these points defines the capture set, which in turn is used to find the capture corridors: these are streams of orbits that can be targeted far away from the planet and that guarantee ballistic capture.</p> <p>The data set is made of two items containing initial conditions of weakly-stable, unstable, crash, moon-crash, and capture sets at Mars. The first is a text file containing initial conditions used to compute time regressions. The second item is a text file containing 100,000 initial conditions generated randomly in the search space and used to compute the quality criterion of the differential algebra mapping. All initial conditions have initial epoch 09 DEC 2023 00:45:18.363 (UTC). The grid of initial conditions is built to maximize the capture ratio for Mars (see Figure 10 in [3]). Initial conditions are propagated in high-fidelity. The equations of motion of the restricted n-body problem including solar radiation pressure are considered.</p> <p>For additional information about the EXTREMA project visit the page <a href="http://extrema.polimi.it">extrema.polimi.it</a>.</p> <p>The data set is associated to the following journal article:</p> <ul> <li> Article: Stable sets mapping with Taylor differential algebra with application to ballistic capture orbits around Mars</li> <li> Journal: Celestial Mechanics and Dynamical Astronomy</li> <li> Authors: Thomas Caleb (corresponding author: thomas.caleb@student.isae-supaero.fr), Gianmario Merisio, Pierluigi di Lizia, and Francesco Topputo</li> <li> DOI: <a href="https://www.doi.org/10.1007/s10569-022-10090-8">10.1007/s10569-022-10090-8</a></li> </ul> <p><strong>References</strong><br> [1] F.

Implementing blended learning for clinician teachers: Identifying their needs and its impact on faculty development initiatives
<p>Learning Technologies has been a fast-growing field in Health Professions Education (HPE). Approaches to teaching, learning and assessment has been increasingly influenced by learning technologies which requires HPE teachers to adapt their teaching practices and with that identify areas for professional development. The implementation of blended learning in HPE, has shown improvements in student performance. However, it seems as if there are challenges with the implementation of a blended learning approach and that there might be some needs that clinical teachers have that are not being addressed in order to implement blended learning successfully. We used a qualitative exploratory design to identify clinician teachers' needs. Semi-structured, individual interviews were conducted with a total of eight (n=8) module coordinators in the third year of the MBChB programme, Stellenbosch University, Faculty of Medicine and Health Sciences. Results indicated the need for continuous technical and pedagogical support which refers to a longitudinal faculty development approach. Additionally, faculty development should include the support in structuring and rethinking the blended curriculum, as well as assisting in the clinicians' development in their role and identity as a clinical teacher. These results reveal the importance of faculty development as a targeted longitudinal approach</p>

Weight stability in adults with obesity initiating medical marijuana treatment
<p>Few studies have evaluated weight change in patients who initiate medical marijuana treatment to address diagnosed health concerns. The objective of this study was to examine whether patients initiating medical marijuana use for a qualifying health condition experienced changes in health and biopsychosocial functioning over time, including weight gain or loss. Specifically, this observational, longitudinal study evaluated changes in the Body Mass Index (BMI) of adults with co-morbid obesity (Body Mass Index [BMI] ≥ 30 kg/m2) and severe obesity (BMI ≥ 40 kg/m2) who were starting medical marijuana treatment for any of the 23 qualifying medical conditions at one of three dispensaries in Pennsylvania. Height and weight measurements were collected at baseline (prior to medical marijuana use) and then 90 days (± 14 days) later. Participants included in analyses (n = 52, M = 55.0 ± 13.6 years, 59.6% female) had a mean baseline BMI of 36.2 ± 5.4 kg/m2 and the majority sought medical marijuana for chronic pain (73.1%). No significant change in BMI was observed from baseline to month three (p > 0.05) in the sample. Additionally, no significant change in BMI was observed in the subset of patients with severe obesity (n = 12, p > 0.05). Our findings are limited by low follow-up rates and convenience sampling methodology but may help to mitigate weight gain concerns in the context of medical marijuana use.</p>

Oxidation of L-leucine amino acid initiated by HO● radical - Are transition metal ions an enhancement factor?
<p class="MsoNormal"><span><span>Hydroxyl radical (HO<sup>●</sup>) formation initiated by the Fenton-type reactions of Fe and Cu complexes of L-leucine (Leu) amino acid, as well as its oxidation reaction by HO<sup>●</sup> were computationally investigated by using the density functional theory (DFT) method at the M05-2X/6-311++G(3df,2pd)//M05-2X/6-311++G(d,p) level of theory in the aqueous phase. The results showed that dipole-salt is the main form of Leu in the physiological condition. Leu exhibits high chelating potential towards both Fe(III)/Fe(II) and Cu(II)/Cu(I) ions with the most favorable coordinating positions at two oxygen atoms of the –COO functional groups. Furthermore, the Leu-ions complexes show a high risk of HO<sup>●</sup> formation <em><span>via</span></em> Fenton-like reactions, especially when ascorbate anion exists in the environment as a reducing agent. Finally, the oxidation reaction of L-leucine by HO<sup>●</sup> demonstrated a relatively high overall apparent reaction rate – </span><em><span>k<sub>overall</sub></span></em><span><span> being 1.18 × 10<sup>9</sup> M<sup>-1</sup>s<sup>-1</sup>,</span><span> </span><span>in which</span><span> </span><span>formal hydrogen transfer (FHT) reactions of the dipole-salt form occur as the primary mechanism. Consequently, the Leu oxidation by HO<sup>●</sup> radical can be promoted by the Fenton-reaction enhancement of its transition metal complexes.</span></span></span></p>
Early nest initiation and vegetation density enhance nest survival in Wild Turkeys
<p>The theory of adaptive habitat selection suggests resource selection by animals should reflect underlying quality, such that individual selection confers an adaptive advantage via increased fitness. Using resource selection functions and nest survival models, we demonstrated that visual obstruction at the nest site was adaptively significant but timing of nest initiation had the greatest effect on nest survival for eastern wild turkeys (Meleagris gallopavo silvestris). Predation risk is a selective pressure, and if individuals can perceive predation risk, they may respond by altering selection of nest site characteristics based on prior experience. We evaluated patterns in nest site selection of 387 wild turkeys and consequences of selection on reproductive success across the southeastern United States from 2014-2019. We monitored 549 nest sites and found that nest initiation date had the strongest effect on daily nest survival rates, wherein adult females at our earliest nest initiation date were ~ 4 times more likely to successfully nest than females at our latest nest initiation dates. Selection of nest sites with greater visual obstruction also increased daily nest survival rates as females were 1.17 (1.100 – 1.234; 95% CI) and 1.37 (1.258 – 1.486; 95% CI) times more likely to select sites for every 10 cm increase in visual obstruction and maximum vegetation height, respectively. Collectively, our results indicate that nest initiation date is likely the critical parameter driving wild turkey nest success, whereas vegetative conditions play a lesser role influencing nest success. Females nesting earlier may be in better body condition and show increased nest attentiveness, which may mediate nest success more than vegetation conditions around nest sites. Our work indicates that increasing the reproductive success of wild turkeys may hinge on females being able to nest as early as possible within the reproductive season.</p>
Conifer seedling demography reveals mechanisms of initial forest resilience to wildfires in the northern Rocky Mountains
<p>Climate warming and an increased frequency and severity of wildfires are expected to transform forest ecosystems, in part through altered post-fire vegetation trajectories. Such a loss of forest resilience to wildfires arises due to a failure to pass through one or more critical demographic stages, or "filters," including seed availability, germination, establishment, and survival. Here we quantify the relative influence of microclimate and microsite conditions on key stages of post-fire seedling demography in two large, lightning-ignited wildfires from the regionally extensive fire season of 2017 in the northern Rocky Mountains, U.S.A. We tracked conifer seedling density, survival, and growth in the first three years post-fire in 69 plots spanning gradients in fire severity, topography, and climate; all plots were limited to within 100 m of a seed source to assure seed availability. Microclimate conditions were inferred based on measurements in a subset of 46 plots. We found abundant post-fire conifer regeneration, with a median of 2,633 seedlings per hectare after three years, highlighting early resilience to wildfire. This robust regeneration was due in part to moderate post-fire climate conditions, supporting high survivorship (>50% on average) of all seedlings tracked over the study period (n = 763). A statistical model based on variables describing potential seed availability, microclimate, fire severity, understory vegetation, and soil nitrogen availability explained 75% of the variability in seedling density among plots. This analysis highlights the overarching importance of fine-scale heterogeneity in fire effects, which determine microclimate conditions and create diverse microsites for seedlings, ultimately facilitating post-fire tree regeneration. Our study elucidates mechanisms of forest resilience to wildfires and demonstrates the utility of a demographic perspective for anticipating forest responses to future wildfires under changing environmental conditions.</p>
Citizen Science Initiatives in Belgium
<p>This dataset contains original mapping data developed in the process of the Belgiuam Citizen Science landscape review. In total, 31 German Citizen Science projects were analysed according to a common framework. During the mapping process, we weren’t always able to find information on things that interested us e.g. project impact, stakeholder engagement, the size of the volunteering force. But just because we couldn’t find something does not mean the results or activities did not happen. It goes without saying that absence of evidence is not evidence of absence. Failure to find some information on our part can be explained by the fact that we worked primarily with internet sources, so we had to make do with whatever publicly available information we could find within reasonable time.</p>
