title: Differences in Persistent Inward Current Contribution to Spinal Motor Neuron Behaviour Between Early Morning and Late Afternoon

description: This repository contains all the raw electromyographic (EMG) data and the edited motor unit spike trains. These data are associated with the following article (link). The repository has been updated following the publication of the associated article.<b>Abstract</b>: Despite the critical role of persistent inward currents (PICs) in modulating motor neuron output, and thus neuromuscular performance, it remains unknown whether their contribution to motor neuron discharge behaviour varies throughout the day. This study aimed to determine whether PIC-related effects on motor neuron activity during submaximal dorsiflexion tasks differ between the early morning and late afternoon. Eighteen healthy adults (4 females; 27.4±5.6 years) performed triangular isometric contractions at two randomized time-points on separate days: early morning (7:00–8:30a.m.) and late afternoon (5:00–7:30p.m.). Two conditions were tested: (1) a <i>relative</i> condition, where the target force corresponded to 40% of the maximal voluntary force (MVF) measured during that session, and (2) an <i>absolute</i> condition, where the target force was 40%MVF recorded during the first session. High-density surface electromyography signals were recorded from the <i>tibialis anterior</i> and decomposed into motor unit spike trains. The prolongation effect of PICs, estimated <i>via</i> ΔF, was significantly greater in the late afternoon in both the relative-absolute force conditions. The amplification effect of PICs, estimated by the acceleration phase of the discharge trajectory, was higher in the late afternoon, but only in the relative force condition. Brace height did not differ between morning and afternoon, but attenuation was lower in the late afternoon during the relative force condition. Collectively, these findings suggest a time-of-day modulation of PIC contribution to motor neuron discharge behaviour, likely mediated by a change in inhibitory–excitatory balance between early morning and late afternoon rather than by changes in neuromodulatory drive.<b>Contact</b>: Bastien Bontemps (<b>Bastien.Bontemps@univ-cotedazur.fr</b>)The original preprint version of this work: https://www.biorxiv.org/content/10.1101/2025.07.30.667593v1

title: Resprouting ability differs among plant functional groups along a soil acidification gradient in a meadow: A rhizosphere perspective

description: Soil acidification as a global change factor can devastatingly affect
 plant growth and productivity. In frequently disturbed ecosystems, plant
 resprouting ability strongly determines biomass reconstruction and
 resilience after aboveground damage. However, how plant regrowth responds
 to soil acidification remains largely unknown, especially regarding the
 role of the rhizosphere in mediating this response. We manipulated a
 soil-acidification gradient via adding purified elemental sulfur powder at
 various rates (0-50 g S m−2 year−1) in a frequently mown meadow. Shoot
 regrowth of functional groups were measured after clipping and supporting
 roles of rhizosphere versus bulk soils were disentangled using isotope
 labelling along the acidification gradient.  Regrowth of grasses
 and sedges increased while forbs decreased along the acidification
 gradient. The results suggest that grasses were competitors capable of
 taking up nutrients from both rhizosphere and bulk soils, while sedges
 were acid-tolerators with lower sensitivity to decreased
 nitrogen-mineralization rates. Forbs, as typical ruderals, were vulnerable
 to N competition with microbes, particularly in the rhizosphere soil.
 Therefore, biomass regrowth of forbs was explained more by physicochemical
 and biological parameters from the rhizosphere than bulk soil Synthesis.
 Divergent interplay between plant functional groups and rhizosphere soils
 was the prominent driver for biomass regrowth responding to soil
 acidification.

title: Phenotypic plasticity and genetic diversity in a polyploid Arabidopsis complex

description: Polyploid species possess more than two sets of chromosomes and may show
 high gene redundancy, hybrid vigor and masking of deleterious alleles
 compared to their parent species. Following this, it is hypothesized that
 this makes them better at adapting to novel environments than their parent
 species, possibly due to phenotypic plasticity. The allopolyploid
 Arabidopsis suecica and its parent species A. arenosa and A. thaliana were
 chosen as a model system to investigate relationships between phenotypic
 plasticity, fitness and genetic variation. Particularly, we test if A.
 suecica is more plastic, show higher genetic diversity and/or have higher
 fitness than its parent species. Wild Norwegian populations of each
 species were analyzed for phenotypic responses to differences in
 availability of nutrient, water and light, while genetic diversity was
 assessed through analysis of AFLP markers. Arabidopsis arenosa showed a
 higher level of phenotypic plasticity and higher levels of genetic
 diversity than the two other species, probably related to its outbreeding
 reproduction strategy. Furthermore, a general positive relationship
 between genetic diversity and phenotypic plasticity was found. Low genetic
 diversity were found in the inbreeding A. thaliana. Geographic spacing of
 populations might explain the clear genetic structure in A. arenosa, while
 the lack of structure in A. suecica could be due to coherent populations.
 Fitness measured as allocation of resources to reproduction, pointed
 towards A. arenosa having lower fitness under poor environmental
 conditions. Arabidopsis suecica, on the other hand, showed tendencies
 towards keeping up fitness under different environmental conditions.
description: These data were generated to investigate phenotypic and genetic
 differences in the allopolyploid species Arabidopsis arenosa Arabidopsis
 suecica (Fr.) Norrl. ex O.E.Schulz and its two parent species, A. thaliana
 (L.) Heynh. and A. arenosa (L.) Lawalrée. Wild Norwegian populations of
 each species were analyzed for phenotypic responses to differences in
 availability of nutrient, water and light, while genetic diversity was
 assessed through analysis of AFLP markers.

title: Bridging macroecology and macroevolution in the radiation of sigmodontine rodents

description: Investigations of phenotypic disparity across geography often ignore
 macroevolutionary processes. As a corollary, the random null expectations
 to which disparity is compared and interpreted may be unrealistic. We
 tackle this issue by representing, in geographical space, distinct
 processes of phenotypic evolution underlying ecological disparity. Under
 divergent natural selection, assemblages in a given region should have
 empirical disparity higher than expected under an evolutionarily-oriented
 null model, while the opposite may indicate constraints on phenotypic
 evolution. We gathered phylogenies, biogeographic distributions, and data
 on the skull morphology of sigmodontine rodents to discover which regions
 of the Neotropics were more influenced by divergent, neutral, or
 constrained phenotypic evolution. We found that regions with higher
 disparity than expected by the evolutionary-oriented null model, in
 terms of both size and shape, were concentrated in the
 Atlantic Forest, suggesting a larger role for divergent natural selection
 there. Phenotypic disparity in the rest of South America, mainly the
 Amazon basin, northeastern Brazil and Southern Andes, was constrained —
 lower than predicted by the evolutionary model. We also demonstrated
 equivalence between the disparity produced by randomization-based null
 models and constrained-evolution null models. Therefore, including
 evolutionary simulations into the null modeling framework used in
 ecophylogenetics can strengthen inferences on the processes
 underlying phenotypic evolution.

title: Icelandic Volcanic Rocks Isotopic Database (IVID)

description: We compile a new geochemical database (Icelandic Volcanic rocks Isotopic
 Database, IVID) which includes previously reported 87Sr/86Sr, 143Nd/144Nd,
 176Hf/177Hf, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 187Os/188Os and
 3He/4He data and major and trace element concentrations measured in
 Icelandic volcanic rocks. Isotopic compositions were evaluated, and
 filtered to identify the highest quality data and data most likely to
 represent mantle-derived compositions. The carefully filtered,
 comprehensive geochemical database is an important contribution to the
 geochemical community and can be used to put further constraints on the
 generation of geochemical heterogeneity in Iceland. We use the compiled
 database to examine the spatial distribution of geochemical components in
 the Icelandic mantle, and test whether melting processes control how
 source heterogeneity from the deep mantle is extracted on the surface. The
 PRIMELT software (which combines an inverse model for crystallization in
 the crust with a forward model of mantle melting to estimate the primary
 mantle-derived magma composition) is used to estimate mantle potential
 temperatures and melt fractions in Iceland. The results of these
 calculations and forward melting models demonstrate that mantle potential
 temperatures have a largely insignificant role and that lithospheric
 thickness plays a key role in generating geochemical heterogeneity in
 Icelandic volcanic rocks. Volcanic rocks from the off-rift volcanic zones
 are generally produced by lower melt fractions, consistent with
 preferential sampling of geochemically enriched and fertile “blobs” at
 lower degrees of melting, where the lithosphere is thicker; more
 geochemically depleted volcanic rocks from the axial rift zones, where the
 lithosphere is thinner, show higher degrees of melting, consistent with
 dilution of enriched blob melts by melts of more depleted and refractory
 mantle.

title: Scalesia atractyloides genome assembly

description: Oceanic archipelagos comprise multiple disparate environments over small
 geographic areas and are isolated from other biotas. These conditions have
 led to some of the most rapid and spectacular phenotypic changes, which
 are often repeated, thus offering a unique chance to characterise its
 genomic basis. These repeated patterns of evolutionary change in plants on
 oceanic archipelagos, or the ‘plant island syndrome’, include changes in
 leaf phenotypes, acquisition of perennial life-style, flowering period and
 self-compatibility, and ancestral ploidy. Here, we describe the genome of
 the critically endangered and Scalesia atractyloides Arnot., type species
 for this Galápagos-endemic genus, obtaining a chromosome-resolved 3.2-Gbp
 assembly with 43,093 candidate gene models. Using a combination of fossil
 transposable elements, k-mer spectra analyses and orthologue assignment,
 we identify the two ancestral subgenomes and date their divergence, and
 the polyploidization event, concluding that the ancestor of all Scalesia
 species on the Galápagos was an allotetraploid. There are a comparable
 number of genes and transposable elements across the two subgenomes, and
 while their synteny has been mostly conserved, we find multiple inversions
 that may have facilitated adaptation. We identify clear signatures of
 selection across genes associated with vascular development, life-growth,
 adaptation to salinity and changes in flowering time, thus finding
 compelling evidence for a genomic basis of island syndrome in one of
 Darwin’s giant daisies. This work advances understanding of factors
 influencing subgenome divergence in polyploid genomes, and characterises
 the quick and pronounced genomic changes in an iconic group of island
 plants.

title: Extreme natural size variation in both sexes of a sexually cannibalistic mantidfly

description: In sexually cannibalistic animals, the relative sizes of potential mates
 often predict the outcome of aggressive encounters. Mantidflies are spider
 egg predators as larvae and generalist predators as adults. Unlike most
 cannibalistic species, individual mantidflies can be substantially larger
 than other individuals, regardless of sex. Using preserved collections of
 Dicromantispa sayi, we focused on three body size metrics that we found to
 be positively correlated and accurately measured across researchers. We
 found extreme size variation in both sexes: the largest 10% of females
 were 1.72x larger than the smallest 10%, and the largest 10% of males were
 1.65x larger than the smallest 10%. On average, females were 7.94% larger
 than males. In exploring possible causes of this variation, we uncovered
 differences among populations. To explore the effect of spider egg sac
 size on adult mantidfly size, we reared mantidfly larvae on egg sacs from
 two jumping spider species with small or large egg sacs. Mantidfly larvae
 reared on small egg sacs were smaller than those reared on large egg sacs.
 This study provides the groundwork to design ecologically relevant
 experiments exploring the causes and consequences of extreme size
 variation in an understudied system with intriguing natural
 history.

title: Phototransduction in a marine sponge provides insights into the origin of animal vision: CEL-Seq2 analyses

description: Most cellular organisms respond to light. In animals, the
 phototransduction system has evolved from localised light-detecting
 photoreceptors to ultimately complex eyes and vision. Here, we investigate
 the origin of metazoan photodetection and transduction by comparing
 well-characterised opsin-based photosystems in neural animals with those
 in the sponge Amphimedon queenslandica. Although sponges lack neurons and
 opsin genes, they can respond rapidly to light. In Amphimedon larva, this
 is guided by the light-sensing posterior pigment ring. We first use cell
 type-specific transcriptomes to reveal that genes that characterise
 eumetazoan Gt- and Go-mediated photosystems are enriched in the Amphimedon
 pigment ring. We then apply a suite of cell signalling pathway agonists
 and antagonists to swimming larvae exposed to directional light. These
 experiments implicate metabotropic glutamate receptors, phospholipase-C,
 protein kinase C and voltage-gated calcium channel in larval phototaxis.
 We find that U-73122-inhibition of phospholipase-C, a key transducer of
 the Gq-mediated pathway, completely reverses phototactic behaviour.
 Together, these results are consistent with aneural sponges sharing with
 neural metazoans an ancestral set of signal transduction pathways that
 have been maintained in these disparate photosensory systems since the
 last common animal ancestor.

title: Gender equality and hiring process in oil mining companies: A case of Lokichar in Turkana, Kenya

description: This paper centers on the findings of a study done by the authors of this
 paper in 2019 titled Change in Gender Roles as a Factor in Gender
 Participation and Empowerment in the Oil Mining Industry: A Case of
 Lokichar, Kenya. One of the objectives; determining whether the oil mining
 companies promotes gender equity in Lokichar is explored. The null
 hypothesis testing on whether there is no relationship between equal
 hiring and equal opportunity for men and women to work in mining
 activities is discussed. The data was collected from a sample of three
 hundred (300) respondents selected through systematic random and purposive
 sampling methods. The studies target group was the active labour force
 aged between 15 to 64 years. Those who retired from work were also
 targeted. Two levels of analysis were adopted: Univariate and Bivariate.
 Chi-square was used to test the hypotheses. Major finding indicates that
 there is a relationship between equal hiring and equal opportunity for men
 and women to work in mining activities. The paper recommends that issues
 like compensation, decision making, royalty sharing, power relations are
 well spelt in policies like the Mining Bill (2014) to ensure gender
 mainstreaming and no ambiguity in interpretation.
description: Two levels of analysis were
 adopted: Univariate and Bivariate. Tabulation and charts were presented to
 show a comparison between
 the various categories. At univariate level one variable at a time was
 analysed to give out characteristic of the variable under study. At
 Bivariate level, two variables are analysed (denoted as X, Y) to assess
 the empirical relationship between them (Singleton et al, 1988:397). Cross
 tabulation was done and Chi Square test of independence test conducted.
 Chi Square test is common for non- parametric
 populations.

title: Bringing Back the Manchester Argus Coenonympha tullia ssp. davus (Fabricius 1777): Quantifying the habitat resource requirements to inform the successful reintroduction of a specialist peatland butterfly

description: 2021-30 has been designated the UN decade of ecosystem restoration.
  A landscape scale peatland restoration project is being
 undertaken on Chat Moss, Greater Manchester, UK, with conservation
 translocations an important component of this work.  The
 Manchester Argus Coenonympha tullia ssp. davus, a specialist butterfly of
 lowland raised bogs in the northwest of England, UK is under threat due to
 severe habitat loss and degradation.  A species reintroduction
 was planned for spring 2020.   This study aimed to quantify the
 resource thresholds for C. tullia, in order to assess potential risks for
 the project.  Thirteen peatland habitat patches with either
 recent historic or current C. tullia populations were surveyed for biotic
 and abiotic factors based on previous qualitative research on the species’
 requirements.   Percentage cover of two habitat resources were
 found to be the strongest predictors in models of C. tullia presence:
 cross-leaved heath Erica tetralix and hair’s-tail cotton-sedge Eriophorum
 vaginatum.   Critical inflection points on logistic regression
 curves were used to make quantitative estimates of the minimum requirement
 of each resource for population survival and the near-optimum abundance of
 each resource.   The results of this study improve our
 understanding of C. tullia’s ecology and the restoration of peatlands for
 its reintroduction.  Additionally, the method has wider utility
 for the quantitative assessment of habitat readiness before attempting
 species reintroductions.

title: Comparative data sets with measurements of tonality and frequency range in passerines and hummingbirds

description: Upper vocal tract articulatory movements are a key component of vocal
 communication across birds and mammals. In many birds, tonal song arises
 from dynamically adjusted filtering of harmonic content. Many aspects of
 these upper vocal tract movements, such as the dynamics, motor control and
 relation to vocal learning, are poorly understood. Here we compare use of
 dynamically adjusted filter properties between vocal learners and
 non-learners to assess whether articulation in the upper vocal tract is
 linked to the increased neural substrate that evolved with vocal learning.
 We hypothesize that vocal learning ability is associated with enhanced
 ability for articulatory movements in the upper vocal tract. To test this
 hypothesis, we compared vocal learners and non-learners from two groups
 (186 passerines and 42 hummingbirds) by assessing tonality of song
 syllables. The data suggest that vocal learners in both clades employ more
 consistent broadband dynamic filter tracking than the non-learners, which
 contributes to the higher tonality in songs. In addition, oscine songs
 display higher tonality than those of hummingbirds. A complex interplay of
 vocal tract biomechanics, histological differences of the sound source as
 well as increased motor control through vocal learning facilitates more
 consistent generation of tonal song.

title: Liquid-liquid phase reaction between crystal violet and sodium hydroxide: kinetic study and precipitate analysis

description: To investigate reaction order and kinetic parameters of the reaction
 between crystal violet (CV) and sodium hydroxide (NaOH), various
 concentrations of the reactants were applied. The present work also
 verifies the unknown solid product produced under highly concentrated
 conditions. The reaction orders of CV and NaOH were determined to be 1 and
 1.17 by pseudo-rate method, respectively, with a rate constant, k, of
 0.084 [(M-1.17) s-1]. In addition to pseudo-rate method, the half-life
 approach is use to calculated the overall reaction order to verify the
 accuracy of pseudo-rate method. The overall reaction order is determined
 to be 1.9 by half-life method. Compare reaction order gained from both
 methods, the overall reaction order is determined as ~2. The precipitate
 formation was observed when high concentrations of CV (0.01~0.1 M) and
 NaOH (1.0 M) were applied. Fourier transform infrared (FTIR) spectroscopy
 was used to compare the spectra of the precipitate generated and a
 commercial solvent violet 9 (SV9). Based on the FTIR spectra, it was
 confirmed that the molecular structure of the precipitate matched that of
 solvent violet 9.
