Personality driven life-history trade-offs differ in two sub-populations of free ranging predators
<p>1) Consistent individual differences in behaviour (i.e. personality) can be explained in an evolutionary context if they are favoured by life-history trade-offs as conceptualized in the pace-of-life syndrome (POLS) hypothesis. Theory predicts that faster growing individuals suffer higher mortality and that this trade-off is mediated through exploration/risk-taking personality, but empirical support for this remains limited and ambiguous. Equivocal support to the POLS hypothesis suggests that the link between life-history and personality may only emerge under certain circumstances. Understanding personality driven trade-offs would be facilitated by long-term studies in wild populations experiencing different ecological conditions.</p> <p>2) Here, we tested whether personality measured in semi-captivity was associated with a growth-mortality trade-off via risk-taking in the wild in two sub-populations of juvenile lemon sharks (Negaprion brevirostris) known to differ in their predator abundance. We expected stronger personality driven trade-offs in the predator-rich environment as compared to the predator-poor environment.</p> <p>3) Sharks were captured yearly from 1995 onwards allowing us to obtain long-term data on growth and apparent survival in each sub-population. We then used a novel open-field assay to test sharks for exploration personality yearly from 2012 to 2017. A subset of the tested sharks was monitored in the field using telemetry to document risk-taking behaviours. We tested (i) if fast explorers in captivity took more risks and grew faster in the wild and (ii) if natural selection acted against more explorative, faster growing sharks.</p> <p>4) In the sub-population with fewer predators, more explorative sharks in captivity took more risks in the wild and grew faster. In turn, larger, fast-growing sharks had lower apparent survival. In the predator-rich sub-population, despite finding selection on fast growth, we found no link between exploration personality and the growth-mortality trade-off.</p> <p>5) Our study demonstrates that the association between personality and life-history is favoured in some ecological contexts but not in others. We identify predator and resource abundance as two main potential drivers of the personality mediated trade-off and emphasize that future work on the POLS hypothesis would benefit from an approach integrating behaviour and life-history across ecological conditions.</p>

Data from: Plastic and evolutionary gene expression responses are correlated in European grayling (Thymallus thymallus) sub-populations adapted to different thermal environments
Understanding how populations adapt to changing environmental conditions is a long-standing theme in evolutionary biology. Gene expression changes have been recognized as an important driver of local adaptation, but relatively little is known regarding the direction of change and in particular, about the interplay between plastic and evolutionary gene expression. We have previously shown that the gene expression profiles of European grayling (Thymallus thymallus) populations inhabiting different thermal environments include both plastic and evolutionary components. However, whether the plastic and evolutionary responses were in the same direction was not investigated in detail, nor was the identity of the specific genes involved. In this study, we show that the plastic changes in protein expression in response to different temperatures are highly correlated with the evolutionary response in grayling subpopulations adapted to different thermal environments. This finding provides preliminary evidence that the plastic response most likely facilitates adaptation during the early phases of colonization of thermal environments. The proteins that showed significant changes in expression level between warm and cold temperature treatments were mostly related to muscle development, which is consistent with earlier findings demonstrating muscle mass differentiation between cold and warm grayling populations.
Profiling of mature stage human breastmilk cells identifies host-defense lactocyte sub-populations
<p>Breastmilk is chock-full of nutrients, immunological factors, and cells that aid infant development. Maternal cells are the least studied breastmilk component, and their unique properties are difficult to identify using traditional techniques. Here, we characterized the cells in mature stage breastmilk from healthy donors at the protein, gene, and transcriptome levels. Holistic analysis of flow cytometry, qPCR, and single cell RNA sequencing data identified the predominant cell population as epithelial with smaller populations of macrophages and T cells. Two percent of epithelial cells expressed four stem cell markers: SOX2, TRA-1-60, NANOG, and SSEA4. Furthermore, milk contained six distinct epithelial lactocyte sub-populations, including three previously unidentified sub-populations programmed towards host-defense and intestinal development. Pseudotime analysis delineated the differentiation pathways of epithelial progenitors. Together, these data define healthy human maternal breastmilk cells and provide a basis for their application in maternal and infant medicine.</p>

Data from: High virulence sub-populations in Pseudomonas aeruginosa long-term cystic fibrosis airway infections
Background: Pseudomonas aeruginosa typically displays loss of virulence-associated secretions over the course of chronic cystic fibrosis infections. This has led to the suggestion that virulence is a costly attribute in chronic infections. However, previous reports suggest that overproducing (OP) virulent pathotypes can coexist with non-producing mutants in the CF lung for many years. The consequences of such within-patient phenotypic diversity for the success of this pathogen are not fully understood. Here, we provide in-depth quantification of within-host variation in the production of three virulence associated secretions in the Liverpool cystic fibrosis epidemic strain of P. aeruginosa, and investgate the effect of this phenotypic variation on virulence in acute infections of an insect host model. Results: Within-patient variation was present for all three secretions (pyoverdine, pyocyanin and LasA protease). In two out of three patients sampled, OP isolates coexisted with under-producing mutants. In the third patient, all 39 isolates were under-producers of all three secretions relative to the transmissible ancestor LESB58. Finally, this phenotypic variation translated into variation in virulence in an insect host model. Conclusions: Within population variation in the production of P. aeruginosa virulence-associated secretions can lead to high virulence sub-populations persisting in patients with chronic CF infections.
