title: Idiosyncratic shifts in life-history traits at species’ geographic range edges

description: Anthropogenic changes drive shifts in species’ geographic distributions
 and increase the occurrence of leading or trailing-edge marginal
 populations. Theoretical predictions and empirical observations indicate
 substantial changes in life-history traits in marginal populations, often
 involving dispersal and reproductive abilities. Using a common garden
 experiment, we studied the variation of life-history traits of populations
 sampled on spatial gradients extending from range-core to range-edge
 habitats for three expanding (miner’s lettuce Claytonia perfoliata, Danish
 scurvygrass Cochlearia danica, and rock samphire Crithmum maritimum) and
 one receding plant species (dune pansy Viola tricolor subs. curtisii). We
 monitored life-history traits related to dispersal, phenology, survival,
 reproductive output, and selfing ability. Significant shifts in
 life-history traits between central and marginal populations strongly
 differed among species. Marginal populations of the three expanding
 species displayed modified seed weight in natura, suggesting increased
 dispersal abilities in leading-edge populations. Discarding unassessed
 maternal effects, this trait modification can be due to phenotypic
 plasticity or to genetic differentiation. In miner’s lettuce, marginal
 expanding populations show advanced phenology and higher reproductive
 output, which may potentially influence their colonization ability. In
 rock samphire, life-history traits showed large intra- and
 inter-population variability that did not follow a core-to-edge geographic
 trend, except for seed size. Finally, the receding populations of the dune
 pansy displayed a shift towards a plant architecture maximizing survival
 but reducing individual reproductive success. Altogether, our results
 indicated a common trend for increased dispersal abilities in marginal
 populations of expanding species. However, shifts in species’
 distributions may drive idiosyncratic changes in other life-history
 traits, for which we observed no general evolutionary syndrome at range
 edges. These findings go along a stochastic view of trait evolution during
 range expansion and question how to draw predictive projections of
 species’ distribution shifts under current global change.
description: This in indicated in the article. Basically,
 seeds were collected for 4 plant species at various locations across their
 geographical range, sown and grown in a common garden, and many
 life-history traits were measured as indicated in the Methods part of the
 paper.

title: Data from: Distributional trends and species richness of Maryland, USA stoneflies (Insecta: Plecoptera), with an emphasis on the Appalachian region

description: Faunistic studies of regional biodiversity of aquatic insects are
 increasing in importance as declines are noted globally. Federal and state
 government conservation attempts for rare and threatened species are
 predicated upon the initial research of specialized taxonomists and
 trained field biologists. Reporting of aquatic insect occurrence data
 provides a baseline for conservation agencies to compare water quality
 monitoring studies. Updated fieldwork, literature reviews, and database
 queries for stoneflies from the mid-Atlantic USA state of Maryland
 necessitated an assessment of species diversity for the state. Seven new
 state records and one new literature record are presented, bringing the
 total number of species to 122. Chao1 estimates of species richness are
 presented for diversity hotspots and the state as a whole, indicating that
 increased sampling is still necessary to fully understand diversity
 patterns. Accompanying are assessments of elevation trends and adult
 presence patterns within nine families. Collections are predominantly
 restricted to the Appalachian region, herein we direct future efforts to
 focus on understudied regions. An outline of distribution knowledge for
 species is presented to inform upcoming State Wildlife Action Plans.
description: Larval and adult stoneflies were collected by the authors during
 the 1990's and from 2020–2022. Collected individuals were preserved
 in 95% ethanol and stored in either Western Kentucky University or Phillip
 N. Hogan Collection. For each collection, GPS coordinates were taken at
 the site location. Literature data were compiled to supplement
 distribution knowledge. Coordinate pair data were identified for
 literature records using locality descriptions. All data have been
 formatted to match Darwin Core Archive standards.

title: Data from: An island endemic born out of hybridization between introduced lineages

description: Humans have profoundly impacted the distribution of plant and animal
 species over thousands of years. The most direct example of these effects
 is human-mediated movement of individuals, either through translocation of
 individuals within their range or the introduction of species to new
 habitats. While human involvement may be suspected in species with obvious
 range disjunctions, it can be difficult to detect natural versus
 human-mediated dispersal events for populations at the edge of a species’
 range, and this uncertainty muddles how we understand the evolutionary
 history of populations and broad biogeographic patterns. Studies combining
 genetic data with archeological, linguistic, and historical evidence have
 confirmed prehistoric examples of human-mediated dispersal; however, it is
 unclear whether these methods can disentangle recent dispersal events,
 such as species translocated by European colonizers during the past 500
 years. We use genomic DNA from historical specimens and historical records
 to evaluate three hypotheses regarding the timing and origin of Northern
 Bobwhites (Colinus virginianus) in Cuba, whose status as an endemic or
 introduced population has long been debated. We discovered that bobwhites
 from southern Mexico arrived in Cuba between the 12th and 16th centuries,
 followed by the subsequent introduction of bobwhites from the southeastern
 USA to Cuba between the 18th and 20th centuries. These dates suggest the
 introduction of bobwhites to Cuba was human-mediated and concomitant with
 Spanish colonial shipping routes between Veracruz, Mexico and Havana, Cuba
 during this period. Our results identify endemic Cuban bobwhites as a
 genetically distinct population born of hybridization between divergent
 introduced lineages.
description: We used a target capture approach appropriate for historical
 specimens (RADcap) to collect thousands of restriction-site associated
 (RAD) loci from 109 bobwhite specimens sampled during the 1850s to the
 1960s throughout mainland Cuba, Isla de la Juventud, and source
 populations in the USA and Mexico. Using phylogenetic, population genetic,
 and demographic analyses in concert with historical records, we evaluated
 the three hypotheses that have been proposed to explain the origin of
 Cuban bobwhites.

title: Black and orange coloration predict success during male-male competition in the guppy

description: Investigating how both intrasexual competition and intersexual mate choice
 act within a single system is crucial to understanding the maintenance and
 diversity of sexually-dimorphic traits. These two processes can act in
 concert by selecting for the same trait, or in opposition by selecting for
 different extremes of the same trait; they can also act on different
 traits, potentially increasing overall trait complexity. We asked whether
 male-male competition and female mate choice act on the same male traits
 using Trinidadian guppies, which exhibit complex male-limited color
 patterns and sexual size dimorphism. We used behavioral assays to assess
 the relationship between color and male competitive success and then
 compared our results to the plethora of data on female choice and male
 color in our study population. We found that males initiated more contests
 if they were larger than their competitor. Males won contests more often
 if they had more black coloration than their competitor, and the effect of
 black was stronger when the male had less orange than his competitor.
 Additionally, males won more often if they had either more structural
 color (iridescence) and more orange, or less structural color and less
 orange than their competitor, suggesting multiple combinations of color
 traits predict success. Females from our study population exhibit strong
 preferences for orange coloration. Thus, traits favored in male contests
 differ from those favored by intersexual selection in this population. Our
 results suggest that mate choice and male-male competition together
 promote increased color pattern complexity in this species.

title: Data for: Multi-campaign ship and aircraft observations of marine cloud condensation nuclei, and droplet concentrations

description: In-situ marine cloud droplet number concentrations (CDNCs), cloud
 condensation nuclei (CCN), and CCN proxies, based on particle sizes and
 optical properties, are accumulated from seven field campaigns, ACTIVATE,
 NAAMES, CAMP2EX, ORACLES, SOCRATES, MARCUS, and CAPRICORN2. Each campaign
 involves aircraft measurements, ship-based measurements, or both.
 Measurements are collected over the North and Central Atlantic,
 Indo-Pacific, and Southern Oceans, representing a range of clean to
 polluted conditions in various climate regimes. With the large range of
 environmental conditions sampled, this collection of data is ideal for
 testing satellite remote detection methods of CDNC and CCN in marine
 environment. Remote measurement methods are key to expanding the available
 data, in these difficult to reach regions of the Earth, and improving our
 understanding of aerosol-cloud interactions. Additional particle
 composition and continental tracers are included to identify potential
 contributing CCN source. Several of these campaigns, include both High
 Spectral Resolution Lidar and polarimetric imaging measurements that will
 be the basis for the next generation of space-based remote sensors and,
 thus, can be utilized as satellite surrogates.
description: This is an aggregated dataset,
 consisting of timeseries with in-situ aircraft or ship campaign
 measurements from ACTIVATE, NAAMES, CAMP2EX, ORACLES,
 SOCRATES, MARCUS, and CAPRICORN2. CCN, CCN proxies and measurements
 necessary to identify particle physical and chemical properties and
 non-marine contributions to particle concentrations are included. All missing or invalid data flags are converted
 to ‘Na’. Some datasets have already been filtered for inlet shattering
 in-cloud, and measurement contamination from ship exhausts; however,
 methods of filtering ship exhaust vary by campaign. For the NAAMES ship
 campaigns, the research ship exhaust was identified and filtered out based
 on the wind direction relative to the ship exhaust and total particle
 counts. For CAPRICORN2, wind direction, total particle counts, black
 carbon particle concentration, and CO and CO<sub>2</sub>
 measurements were also utilized in filtering ship
 exhaust. Finally, the
 MARCUS ship exhaust contamination periods are identified and filtered
 using total particle counts and CO measurements. The aggregated dataset is further filtered to
 eliminate measurements influenced by in-cloud inlet shattering and
 averaged at 10 second intervals for aircraft measurements and 5-minute
 intervals for ship measurements (except for CAPRICOR2 which is only
 publicly available at hourly averaged intervals).

title: Data from: Impact of human foraging on tree diversity, composition and abundance in a tropical rainforest

description: These are summarised plot data from fifteen 40 m by 40 m sample plots
 established in Oban Division of Cross River National Park, Nigeria,
 between 23rd August 2019 and 9th September 2019. We have also included
 data summaries and RStudio codes used for analysis and generating results
 for the manuscript entitled: "Impact of human foraging on tree
 diversity, composition and abundance in a tropical rainforest",
 submitted for publication as an original research article in Biotropica.
 All data and R code required to generate the results as shown in the
 manuscript have been included. Complete tree species and plot data can be
 accessed at https://forestplots.net/.
description: Fifteen permanent sample plots of 40 by 40 m dimension were
 established along an elevational gradient rising from about 100 m to 500m
 above sea level between 23rd August 2019 and 9th September 2019. Five plot
 clusters with three plots each were established in three areas of the
 forest: one cluster in Erukut, two in Aking and two in Osomba, making a
 total of 15 sample plots with a total area of 2.4 hectares. Due to the
 steep topography of Aking and Osomba locations, plots were established at
 closer horizontal intervals based on elevational differences of about 20
 m. All trees with a minimum of 10 cm dbh in all 15
 plots were measured and tagged with a unique number. The collected data
 included plot information (plot number and GPS coordinate of the four
 corners of plots using Garmin eTrex 10 Outdoor Handheld GPS Unit), tree
 dbh (diameter of a tree at 1.30 m from the base) using a diameter tape and
 LaserAce 1000 rangefinder for points of measurement too high for a
 diameter tape, species name, assigned tag number, and species group
 (edible and inedible species). Measurement of buttress trees, folk trees,
 leaning trees or trees on a slope was completed using the African Tropical
 Rainforest Observation Network (AfriTRON) protocol. Trees were identified
 to species level by a field taxonomist and in cases where there was
 uncertainty in the identification of species, tree locations were noted,
 and specimens were collected and stored in herbarium presses for further
 taxonomic work.

title: Data for: Corticosteroid-binding globulin (SERPINA6) establishes postpubertal sex differences in rat adrenal development

description: Encoded by SerpinA6, plasma corticosteroid-binding globulin (CBG)
 transports glucocorticoids and regulates their access to cells. We
 determined how CBG influences plasma corticosterone and adrenal
 development in rats during the pubertal to adult transition using
 CRISPR/cas9 to disrupt SerpinA6 gene expression. In the absence of CBG,
 total plasma corticosterone levels were ∼80% lower in adult rats of both
 sexes, with a greater absolute reduction in females than in males.
 Notably, free corticosterone and adrenocorticotropic hormone were
 comparable between all groups. Between 30 and 90 days of age, wild-type
 female rats showed increases in adrenal weight and the size of the
 corticosterone-producing region, the zona fasciculata (zf), in tandem with
 increases in plasma CBG and corticosterone concentrations, whereas no such
 changes were observed in males. This sex difference was lost in rats
 without CBG, such that adrenal growth and zf expansion were similar
 between sexes. The sex-specific effects of CBG on adrenal morphology were
 accompanied by remarkable changes in gene expression: ∼40% of the adrenal
 transcriptome was altered in females lacking CBG, whereas almost no effect
 was seen in males. Over half of the adrenal genes that normally exhibit
 sexually dimorphic expression after puberty were similarly expressed in
 males and females without CBG, including those responsible for cholesterol
 biosynthesis and mobilization, steroidogenesis, and growth. Rat adrenal
 SerpinA6 transcript levels were very low or undetectable. Thus, sex
 differences in adrenal growth, morphology and gene expression profiles
 that emerge during puberty in rats are dependent on concomitant increases
 in plasma CBG produced by the liver.

title: Long-term effect of forest harvesting on boreal species assemblages under climate change

description: Logging is the main human disturbance impacting biodiversity in forest
 ecosystems. However, the impact of forest harvesting on biodiversity is
 modulated by abiotic conditions through complex relationships that remain
 poorly documented. Therefore, the interplay between forest management and
 climate change can no longer be ignored. Our aim was to study the expected
 long-term variations in the assemblage of bird and beetle communities
 following modifications in forest management under different climate
 change scenarios. We developed species distribution models to predict the
 occurrence of 88 species of birds and beetles in eastern Canadian boreal
 forests over the next century. We simulated three climate scenarios
 (baseline, RCP4.5 and RCP8.5) under which we varied the level of
 harvesting.   We also analyzed the regional assemblage
 dissimilarity by decomposing it into balanced variations in species
 occupancy and occupancy gradient. We predict that forest harvesting will
 alter the diversity by increasing assemblage dissimilarity under all the
 studied climate scenarios, mainly due to species turnover. Species
 turnover intensity was greater for ground-dwelling beetles, probably
 because they have lower dispersal capacity than flying beetles or birds. A
 good dispersal capacity allows species to travel more easily between
 ecosystems across the landscape when they search for suitable habitats
 after a disturbance. Regionally, an overall increase in the probability of
 occupancy is projected for bird species, whereas a decrease is predicted
 for beetles, a variation that could reflect differences in ecological
 traits between taxa. Our results further predict a decrease in the number
 of species that increase their occupancy after harvest under the most
 severe climatic scenario for both taxa.  We anticipate that under
 severe climate change, increasing forest disturbance will be detrimental
 to beetles associated with old forests but also with young forests after
 disturbances.

title: Analysis of the extent of limbic system changes in multiple sclerosis using FreeSurfer and voxel-based morphometry approaches

description: Background and Purpose: The limbic brain is involved in diverse cognitive,
 emotional, and autonomic functions.  Injury of the various parts
 of the limbic system have been correlated with clinical deficits in
 MS.  The purpose of this study was to comprehensively examine
 different regions of the subcortical limbic system to assess the extent of
 damage within this entire system as it may be pertinent in correlating
 with specific aspects of cognitive and behavioral dysfunction in MS by
 using a fully automated, unbiased segmentation approach. 
 Results: The mean [95% confidence interval] of the total limbic system
 volume was lower (0.22% [0.21-0.23]) in MS compared to healthy controls
 (0.27%, [0.25-0.29], p &lt; .001).  Pairwise comparisons of
 individual limbic regions between MS and controls was significant in the
 nucleus accumbens (0.046%, [0.043-0.050]  vs. 0.059%,
 [0.051-0.066],  p = .005), hypothalamus  (0.062%,
 [0.059-0.065] vs. 0.074%, [0.068-0.081], p = .001), basal forebrain
 (0.038%, [0.036-0.040] vs. 0.047%, [0.042-0.051], p = .001), hippocampus
 (0.47%, [0.45-0.49] vs. 0.53%, [0.49-0.57], p = .004), and anterior
 thalamus (0.077%, [0.072-0.082] vs. 0.093%, [0.084-0.10], p = .001) after
 Bonferroni correction.  Volume of several limbic regions was
 significantly correlated with T2 lesion burden and brain parenchymal
 fraction (BPF).  Multiple regression model showed minimal
 influence of BPF on limbic brain volume and no influence of other
 demographic and disease state variables.  VBM analysis showed
 cluster differences in the fornix and anterior thalamic nuclei at
 threshold p &lt; 0.05 after adjusting for covariates but the results
 were insignificant after family-wise error corrections. 
   Conclusions: The results show evidence that brain volume loss
 is fairly extensive in the limbic brain.   
 Given the significance of the limbic system in many disease states
 including MS, such volumetric analyses can be expanded to studying
 cognitive and emotional disturbances in larger clinical trials. 
 FreeSurfer ScLimbic pipeline provided an efficient and reliable
 methodology for examining many of the subcortical structures related to
 the limbic brain.   
description: Sixty-seven subjects were included in this study, including 52
 with multiple sclerosis (MS) and 15 healthy controls. Only patients with
 stable MS disease, without any relapses, MRI activity, or disability
 progression were included. Subcortical limbic system segmentation was
 performed using the FreeSurfer pipeline ScLimbic, which provides volumes
 for fornix, mammillary bodies, hypothalamus, septal nuclei, nucleus
 accumbens, and basal forebrain. Hippocampus and anterior thalamic nuclei
 were added as additional components of the limbic circuitry, also
 segmented through FreeSurfer. Whole limbic region mask was generated by
 combining these structures and used for Voxel-based morphometry (VBM)
 analysis.
