IODP Expedition 369 Interstitial water composite report
<p>This composite report includes data from numerous interstitial water (IW) analyses (e.g., ICP-LIQUIDS and IONCHROM) in a variable set of columns. Each row combines the data from several tests (groups of measurements made on the same sample at the same time) for a particular IW sample. If data do not exist for a particular expedition, the column does not appear. To identify individual samples and tests, see each separate analysis (ALKALINITY, ICP-LIQUIDS, IONCHROM, SALINITY, SPEC, TITRATOR, and potentially others). Major and minor elements were determined by inductively coupled plasma-atomic emission spectrocsopy (ICP-LIQUIDS). Cations and anions were measured by ion chromatography (IONCHROM). Complex ions were measured by colorimetric measurements using a UV-VIS spectrometer (SPEC). Alkalinity and chloride was measured by titration (ALKALINITY and TITRATOR). Dissolved carbon (DC), dissolved inorganic carbon (DIC), and dissolved organic carbon (DOC) were measured by combustion in a total organic carbon (TOC) analyzer. Salinity was measured by refractometer (SALINITY). pH was measured by ion-selective electrode as part of the alkalinity procedure and is reported in the ALKALINITY analysis.</p>

Sustained mangrove reproduction despite major turnover in pollinator community composition at expanding range edge
<p><strong>Background and Aims</strong></p> <p>How well plants reproduce near their geographic range edge can determine whether distributions will shift in response to changing climate. Reproduction at the range edge can be limiting if pollinator scarcity leads to pollen limitation, or if abiotic stressors affect allocation to reproduction. For many animal-pollinated plants with expanding ranges, the mechanisms by which they have overcome these barriers are poorly understood.</p> <p><strong>Methods </strong></p> <p>In this study, we examined plant-pollinator interactions hypothesized to impact reproduction of the black mangrove, <em>Avicennia germinans</em>, which is expanding northward in coastal Florida, USA. We monitored insects visiting <em>A. germinans</em> populations varying in proximity to the geographic range edge, measured the pollen loads of the most common insect taxa and pollen receipt by <em>A. germinans</em> stigmas, and quantified flower and propagule production. <strong> </strong></p> <p><strong>Key Results</strong></p> <p>We found that despite an 84% decline in median floral visits by insects at northernmost vs. southernmost sites, range-edge pollen receipt remained high. Notably, local floral visitor assemblages exhibited substantial turnover along the study's latitudinal gradient, with large-bodied bees and hover flies increasingly common at northern sites. We also observed elevated flower production in northern populations and higher per capita reproductive output at the range edge. Furthermore, mean propagule mass in northern populations was 18% larger than propagules from the southernmost populations. <strong> </strong></p> <p><strong>Conclusions</strong></p> <p>These findings reveal no erosion of fecundity in <em>A. germinans</em> populations at range limits, allowing rapid expansion of mangrove cover in the region. These results also illustrate that substantial turnover in the assemblage of flower-visiting insects can occur at an expanding range edge without altering pollen receipt.</p>

Microbial community composition of earthworm-invaded and earthworm-free soils of the Canadian boreal forest
<p>Earthworm invasion in North American forests has the potential to greatly impact soil microbiomes by altering soil physicochemical properties. We characterized and compared microbial communities of earthworm-invaded and non-invaded soils in previously described sites across three major soil types found in the Canadian boreal forest using phospholipid fatty acid (PLFA) analysis and metabarcoding of the 16S rRNA gene (bacteria and archaea) and ITS2 region (fungi).</p>
Data from: Genotype-by-environment interactions influence the composition of the Drosophila seminal proteome
<p>Ejaculate proteins are key mediators of post-mating sexual selection and sexual conflict, as they can influence both male fertilization success and female reproductive physiology. However, the extent and sources of genetic variation and condition dependence of the ejaculate proteome are largely unknown. Such knowledge could reveal the targets and mechanisms of post-mating selection and inform about the relative costs and allocation of different ejaculate components, each with its own potential fitness consequences. Here, we used liquid chromatography coupled with tandem mass spectrometry to characterize the whole-ejaculate protein composition across twelve isogenic lines of Drosophila melanogaster that were reared on a high- or low-quality diet. We discovered new proteins in the transferred ejaculate and inferred their origin in the male reproductive system. We further found that the ejaculate composition was mainly determined by genotype identity and genotype-specific responses to larval diet, with no clear overall diet effect. Nutrient restriction increased proteolytic protein activity and shifted the balance between reproductive function and RNA metabolism. Our results open new avenues for exploring the intricate role of genotypes and their environment in shaping ejaculate composition, or for studying the functional dynamics and evolutionary potential of the ejaculate in its multivariate complexity.</p>

Data from: Seasonal restructuring facilitates compositional convergence of gut microbiota in free-ranging rodents
<p>Gut microbes provide essential services to their host and shifts in their composition can impact host fitness. However, despite advances in our understanding of how microbes are assembled in the gut, we understand little about the stability of these communities within individuals, nor what factors influence its composition over the life of an animal. For this reason, we conducted a longitudinal survey of the gut microbial communities of individual free-ranging woodrats (<em>Neotoma</em> spp.) across a hybrid zone in the Mojave Desert, USA, using amplicon sequencing approaches to characterize gut microbial profiles and diet. We found that gut microbial communities were individualized and experienced compositional restructuring as a result of seasonal transitions and changes in diet. Turnover of gut microbiota was highest amongst bacterial subspecies and was much lower at the rank of Family, suggesting there may be selection for conservation of core microbial functions in the woodrat gut. Lastly, we identified an abundant core gut bacterial community that may aid woodrats in metabolizing a diet of plants and their specialized metabolites. These results demonstrate that the gut microbial communities of woodrats are highly dynamic and experience seasonal restructuring which may facilitate adaptive plasticity in response to changes in diet. </p>

Suppression of Bend Instability in Microtubule-fd Virus Composite Active Nematics by External Magnetic Field
<p>The shear flow-aligned active nematic within a cuboidal channel is subjected to an external magnetic field (1.8T) in the aligned nematic direction. In the absence of the magnetic field, bend deformations proliferate, generating flows perpendicular to the initial alignment, as seen in the control case where no external field is applied (PIV vectors overlaid on the image for visual representation). Under the influence of the magnetic field, the bend instabilities are quelled, as there are no flows perpendicular to the applied field. Tracer beads are utilized for brightfield imaging in the magnetic field apparatus to distinguish between the conditions, while fluorescently labeled microtubules are observed in the control scenario.</p>
