Data from: Subcortical heterotopic gray matter brain malformations: classification study of 107 individuals

Objective: To better evaluate the imaging spectrum of subcortical heterotopic grey matter brain malformations (SUBH), we systematically reviewed neuroimaging and clinical data of 107 affected individuals. Methods: SUBH is defined as heterotopic gray matter, located within the white matter between the cortex and lateral ventricles. Four large brain malformation databases were searched for individuals these malformations; data on imaging, clinical outcomes and results of molecular testing were systematically reviewed and integrated with all previously published subtypes to create a single classification system. Results: Review of the databases revealed 107 patients with SUBH, the large majority scanned during childhood (84%), including more than half before 4 years (59%). Although most individuals had cognitive and/or motor disability, 19% had normal development. Epilepsy was documented in 69%. Additional brain malformations were common and included abnormalities of the corpus callosum (65/102, 64%), and, often, brainstem or cerebellum (47/106, 44%). Extent of the HET (unilateral or bilateral) did not influence the presence or age of onset of seizures. Although genetic testing was not systematically performed in this group, the sporadic occurrence and frequent asymmetry suggests either postzygotic mutations or prenatal disruptive events. Several rare, bilateral forms are caused by mutations in genes associated with cell proliferation and polarity (EML1, TUBB, KATNB1, CENPJ, GPSM2). Conclusion: This study reveals a broad clinical and imaging spectrum of heterotopic malformations and provides a framework for their classification.

Individual genotypes of 1 416 brook trout genotyped at 14 779 high-quality SNPs for studying local adaptation and maladaptation in small populations

<p><span><span><span><span><span><span><span><span><span><span><span>Investigating the relative importance of neutral <i>versus</i> selective processes governing the accumulation of genetic variants is a key goal in both evolutionary and conservation biology. This is particularly true in the context of small populations, where genetic drift can counteract the effect of selection. Using Brook Charr (<i>Salvelinus fontinalis</i>) from Québec, Canada as a case study, we investigated the importance of demographic <i>versus</i> selective processes governing the accumulation of both adaptive and maladaptive mutations in closed <i>versus</i> open and connected populations to assess gene flow effect. This was achieved by using 14 779 high-quality filtered SNPs genotyped among 1 416 fish representing 50 populations from three life history types: lacustrine (closed populations), riverine and anadromous (connected populations). Using the Provean algorithm, we observed a considerable accumulation of putative deleterious mutations across populations. The absence of correlation between the occurrence of putatively beneficial or deleterious mutations and local recombination rate supports the hypothesis that genetic drift might be the main driver of the accumulation of such variants. However, despite a lower genetic diversity observed in lacustrine than in riverine or anadromous populations, lacustrine populations do not exhibit more deleterious mutations than the two other history types, suggesting that the negative effect of genetic drift in lacustrine populations may be mitigated by that of relaxed purifying selection. Moreover, we also identified genomic regions associated with anadromy, as well as an overrepresentation of transposable elements associated with variation in environmental variables, thus supporting the importance of transposable elements in adaptation. </span></span></span></span></span></span></span></span></span></span></span></p>

Data from: Individual and combined impacts of sulfoxaflor and Nosema bombi on bumblebee (Bombus terrestris) larval growth

<p>Sulfoxaflor is a globally important novel insecticide that can have negative impacts on the reproductive output of bumblebee (<i>Bombus terrestris</i>) colonies. However, it remains unclear as to which life-history stage is critically affected by exposure. One hypothesis is that sulfoxaflor exposure early in the colony's life cycle can impair larval development, reducing the number of workers produced, and ultimately lowering colony reproductive output. Here we assess the influence of sulfoxaflor exposure on bumblebee larval mortality and growth both when tested in insolation and when in combination with the common fungal parasite <i>Nosema bombi, </i>following a pre-registered design. We found no impact of sulfoxaflor (5ppb) or <i>N. bombi</i> exposure (50,000 spores) on larval mortality when tested in isolation but found an additive, negative effect when larvae received both stressors in combination. Furthermore, we found that sulfoxaflor and <i>N. bombi </i>exposure individually impaired larval growth but also found possible antagonistic effects when used in combination. Ultimately, our results suggest that colony-level consequences of sulfoxaflor exposure for bumblebees may be mediated through direct effects on larvae. As sulfoxaflor is licenced for use globally, our findings highlight the need to understand how novel insecticides impact non-target insects at various stages of their development. </p>

Individual species provide multifaceted contributions to the stability of ecosystems_Dataset

<p>Abstract</p> <p>Exploration of the relationship between species diversity and ecological stability has occupied a prominent place in ecological research for decades. Yet, a key component of this puzzle&mdash;the contributions of individual species to the overall stability of ecosystems&mdash;remains largely unknown. Here, we show that individual species simultaneously stabilize and destabilize ecosystems along different dimensions of stability, and also that their contributions to functional (biomass) and compositional stability are largely independent. By simulating experimentally the extinction of consumer species from a coastal rocky shore, we found that the capacity to predict the combined contribution of species to stability from the sum of their individual contributions varied among stability dimensions. This implies that the nature of the diversity-stability relationship depends upon the dimension of stability under consideration, and may be additive, synergistic or antagonistic. We conclude that, though the profoundly multifaceted and context-dependent consequences of species loss pose a significant challenge, the predictability of cumulative species contributions to some dimensions of stability provide a way forward for ecologists trying to conserve ecosystems and manage their stability under global change.</p> <p>Methods</p> <p>This dataset contains species abundance matrices for monthly suveys of experimental plots at Glashagh bay, Fanad, Co. Donegal, Ireland (55&deg;26&rsquo;5&rsquo;&rsquo;N, 7&deg;67&rsquo;5&rsquo;&rsquo;W) over 15 months from May 2016. We measured the percent cover of macroalgae monthly using a 25 x 25 cm quadrat with 64 intersections, positioned centrally within cages to avoid sampling edge effects. Species present within the quadrat but not occurring underneath any of the intersections were assigned a cover value of 1%. We used the data set to&nbsp;quantify six components of ecological stability, separately for both total algal cover (as a proxy for total algal biomass) and assemblage structure as measures of, respectively, functional and&nbsp;compositional stability. Please see&nbsp;Table 1 and methods section&nbsp;in the associated&nbsp;manuscript for details on calculating stability measures.&nbsp;</p> <p>Usage Notes</p> <p>Please see readme in the datafile&nbsp;for explanations of experimental treatments, survey methods and species abreviations.&nbsp;</p>

Data from: Negative effects of individual heterozygosity on reproductive success in a wild bird population

<p>The evolutionary consequences of individual genetic diversity are frequently studied by assessing heterozygosity-fitness correlations (HFCs). The prevalence of positive and negative HFCs and the predominance of general versus local effects in wild populations are far from understood, partly because comprehensive studies testing for both inbreeding and outbreeding depression are lacking. We studied a genetically diverse population of blue tits in southern Germany using a genome-wide set of 87 microsatellites to investigate the relationship between proxies of reproductive success and measures of multi-locus and single-locus individual heterozygosity (MLH and SLH). We used complimentary measures of MLH and partitioned markers into functional categories according to their position in the blue tit genome. HFCs based on MLH were consistently negative for functional loci, whereas correlations were rather inconsistent for loci found in non-functional areas of the genome. Clutch size was the only reproductive variable showing a general effect. We found evidence for local effects for three measures of reproductive success: arrival date at the breeding site, the probability of breeding at the study site, and male reproductive success. For these, we observed consistent, and relatively strong, negative effects at one functional locus. Remarkably, this marker had a similar effect in another blue tit population from Austria (~400 km to the east). We suggest that a genetic local effect on timing of arrival might be responsible for most negative HFCs detected, with carry-over effects on other reproductive traits. This effect could reflect individual differences in the distance between overwintering areas and breeding sites.</p>

Genetic architecture of individual variation in recombination rate on the X-chromosome in cattle

<p class="Standard"><span>Meiotic recombination is an essential biological process that ensures proper chromosome segregation and creates genetic diversity. Individual variation in global recombination rates has been shown to be heritable in several species and variants significantly associated with this trait have been identified. Recombination on the sex chromosome has often been ignored in these studies although this trait may be particularly interesting as it may correspond to a biological process distinct from that on autosomes. For instance, recombination in males is restricted to the pseudo-autosomal region (PAR). We herein used a large cattle pedigree with more than 100,000 genotyped animals to improve the genetic map of the X-chromosome and to study the genetic architecture of individual variation in recombination rate on the sex-chromosome (XRR). The length of the genetic map was 46.4 and 121.2 cM in males and females, respectively, but the recombination rate in the PAR was 6 times higher in males. The heritability of CO counts on the X-chromosome was comparable to that of autosomes in males (0.011) but larger than that of autosomes in females (0.024). XRR was highly correlated (0.76) with global recombination rate (GRR) in females, suggesting that both traits might be governed by shared variants. In agreement, a set of eleven previously identified variants associated with GRR had correlated effects on female XRR (0.86). In males, XRR and GRR appeared to be distinct traits, although more accurate CO counts on the PAR would be valuable to confirm these results. </span></p>

Code for Individual Based Model to assess impact of KHV release on carp population

<p><b>1: </b>Common carp (<i>Cyprinus carpio</i>) is one of the top global invasive vertebrates and can cause significant ecological damage. The Australian Government's National Carp Control Program (NCCP) proposes to release Koi Herpesvirus (KHV) to eradicate feral carp in one of the largest ecological interventions ever attempted. Ecological and human health risks have been highlighted regarding the release of a highly pathogenic viral biocontrol for an aquatic species. The efficacy of KHV has also been questioned, and it has not been demonstrated to produce lasting population reductions.</p> <p> </p> <p>2. We developed an individual-based model (IBM) to examine the ecological and evolutionary response of a carp population after KHV release. This simulated the interaction between fish life history, viral epidemiology, host genetic resistance and population demography to critically evaluate the impact of KHV release under optimal conditions and a "best case scenario" for disease transmission.</p> <p> </p> <p>3. KHV will rarely result in prolonged reductions or population extinctions. Crucially, realistic scenarios result in a rapidly rebounding population of resistant individuals. Additional measures aimed to reduce carp population recovery rate (e.g. with genetic engineering) require rapid efficacy to significantly reduce carp numbers alongside KHV.<br>  </p> <p>4. Fish fecundity has an overwhelming influence on viral efficacy as a biocontrol agent when combined with genetic resistance within a population. A high probability of population extinction is only met when carp fecundity is reduced to 1% of biological observations.<br>  </p> <p><span>5.<i> Synthesis and applications. </i></span>We use an individual-based model to  evaluate the efficacy of Koi Herpesvirus biocontrol in Common <a>Ca</a>rp, and find that high host fecundity combined with genetic resistance results in rapid population rebound after initial large fish-kills. Biocontrol approaches relying on natural selection lose efficacy over successive generations as resistance genes increases in frequency. Given the intense logistical effort and risks to ecosystems and human health associated with large fish kills after viral release, we suggest that sustained manual removal, alongside ecological restoration to favour recovery of native species, provides a risk-free approach to reducing populations.<br>  </p>

Becoming creatures of habit: among- and within-individual variation in nesting behavior shifts with age

<p>The quantification of repeatability has enabled behavioral and evolutionary ecologists to assess the heritable potential of traits. For behavioral traits that vary across life, age-related variation should be accounted for to prevent biasing the microevolutionary estimate of interest. Moreover, to gain a mechanistic understanding of ontogenetic variation in behavior, among- and within-individual variance should be quantified across life. We leveraged a 30-year study of painted turtles (<i>Chrysemys picta</i>) to assess how age contributes to variation in the repeatability of nesting behaviors. We found that four components of nesting behavior were repeatable, and that accounting for age increased the repeatability estimate for maternal choice of canopy cover over nests. We detected canalization (diminished within-individual variance with age) of canopy cover choice in a reduced dataset despite no shift in repeatability. Additionally, random regression analysis revealed that females became more divergent from each other in their choice of canopy cover with age. Thus, properly modeling age-related variance should more precisely estimate heritable potential, and assessing among- and within-individual variance components in addition to repeatability will offer a more mechanistic understanding of behavioral variation across age.</p>

Individual differences in risk‐taking affect foraging across different landscapes of fear

<p>One of the strongest determinants of behavioural variation is the tradeoff between resource gain and safety. Although classical theory predicts optimal foraging under risk, empirical studies report large unexplained variation in behaviour. Intrinsic individual differences in risk-taking behaviour might contribute to this variation. By repeatedly exposing individuals of a small mesopredator to different experimental landscapes of risks and resources, we tested 1) whether individuals adjust their foraging behaviour according to predictions of the general tradeoff between energy gain and predation avoidance and 2) whether individuals differ consistently and predictably from each other in how they solve this tradeoff. Wild-caught individuals (n = 42) of the jumping spider <em>Marpissa muscosa</em>, were subjected to repeated release and open-field tests to quantify among-individual variation in boldness and activity. Subsequently, individuals were tested in four foraging tests that differed in risk level (white/dark background colour) and risk variation (constant risk/variable risk simulated by bird dummy overflights) and contained inaccessible but visually perceivable food patches. When exposed to a white background, individuals reduced some aspects of movement and foraging intensity, suggesting that the degree of camouflage serves as a proxy of perceived risk in these predators. Short pulses of acute predation risk, simulated by bird overflights, had only small effects on aspects of foraging behaviour. Notably, a significant part of variation in foraging was due to among-individual differences across risk landscapes that are linked to consistent individual variation in activity, forming a behavioural syndrome. Our results demonstrate the importance of among-individual differences in behaviour of animals that forage under different levels of perceived risk. Since these differences likely affect food-web dynamics and have fitness consequences, future studies should explore the mechanisms that maintain the observed variation in natural populations.</p>

Three-dimensional surface models of hand bones (individual 15-06)

<p><b>Objectives</b>: Cuncaicha, a rockshelter site in the southern Peruvian Andes, has yielded archaeological evidence for human occupation at high elevation (4480 masl) during the Terminal Pleistocene (12,500 to 11,200 cal BP), Early Holocene (9500-9000 cal BP), and later periods. One of the excavated human burials (Feature 15-06), corresponding to a middle-aged female dated to ~8500 cal BP, exhibits skeletal osteoarthritic lesions previously proposed to reflect habitual loading and specialized crafting labor. Three small tools found in association with this burial are hypothesized to be associated with precise manual dexterity.</p> <p><b>Materials and Methods:</b> Here, we tested this functional hypothesis through the application of a novel multivariate methodology for the three-dimensional analysis of muscle attachment surfaces (entheses). This original approach has been recently validated on both lifelong-documented anthropological samples as well as experimental studies in non-human laboratory samples. Additionally, we analyzed the three-dimensional entheseal shape and resulting moment arms for muscle <i>opponens pollicis.</i></p> <p><b>Results: </b>Results show that Cuncaicha individual 15-06 shows a distinctive entheseal pattern associated with habitual precision grasping via thumb-index finger coordination, which is shared exclusively with documented long-term precision workers from recent historical collections. The separate geometric morphometric analysis revealed that the individual's <i>opponens pollicis</i> enthesis presents a highly projecting morphology, which was found to strongly correlate with long joint moment arms (a fundamental component of force-producing capacity), closely resembling the form of Paleolithic hunter-gatherers from diverse geo-chronological contexts of Eurasia and North Africa.</p> <p><b>Discussion:</b> Overall, our findings provide the first bio-cultural evidence to confirm that the lifestyle of some of the earliest Andean inhabitants relied on habitual and forceful precision grasping tasks.</p>
