Partner fidelity and environmental filtering preserve stage-specific turtle ant gut symbioses for over 40 million years

Sustaining beneficial gut symbioses presents a major challenge for animals, Including holometabolous insects. Social insects may meet such challenges through behavioral symbiont transfer and transgenerational inheritance through colony founders. We address such potential through colony-wide explorations across 13 eusocial, holometabolous ant species in the genus Cephalotes. Through amplicon sequencing and qPCR, we show that previously characterized worker microbiomes are largely conserved across adult castes, that adult microbiomes exhibit strong trends of phylosymbiosis, and that Cephalotes cospeciate with their most abundant adult symbionts. We find, also, that winged queens harbor worker-like microbiomes prior to colony founding, suggesting that vertical inheritance promotes ancient partner fidelity. While some adult-abundant symbionts colonize guts of larvae, microbiomes from this stage are by environmental bacteria from the Enterobacteriales, Lactobacillales, and Actinobacteria. Re-acquisition of such bacteria, each generation, for >40 million years suggests conserved environmental filtering and, hence, a second mechanism behind distinct symbioses divided by metamorphosis.

Early stages of speciation with gene flow in the Amazilia Hummingbird (Amazilis amazilia) subspecies complex of Western South America

Disentangling the factors underlying the diversification of geographically variable species with a wide geographical range is essential to understanding the initial stages and drivers of the speciation process. The Amazilia Hummingbird, Amazilis amazilia, is found along the Pacific coast from northern Ecuador down to the Nazca Valley of Peru, and is currently classified as six phenotypically differentiated subspecies. Our aims were to resolve the evolutionary relationships of the six subspecies, to assess the geographical pattern and extent of evolutionary divergence, and to test for introgression using both a mtDNA marker and a genome-by-sequencing dataset from 86 individuals from across the species range. The consensus phylogenetic tree separated the six subspecies into three distinct clades, corresponding with the Ecuador lowlands (A. amazilia dumerilii), the Ecuador highlands (A. amazilia alticola and A. amazilia azuay), and the Peruvian coast (A. amazilia leucophoea, A. amazilia amazilia, and A. amazilia caeruleigularis). However, an unresolved mtDNA network suggests that the diversification of the subspecies was recent and rapid. We found evidence of gene flow among the subspecies A. amazilia dumerilii, A. amazilia alticola, and A. amazilia leucophoea, with strong genetic isolation of the subspecies A. amazilia azuay in the isolated Yunguilla Valley of Ecuador. Finally, environmental data from each subspecies' capture locations were concordant with the three distinct clades. Overall, our results suggest that both expansion into new habitats and geographic isolation shaped the present-day phylogeny and range of the A. amazilia subspecies, and that A. amazilia azuay may be genetically divergent enough to be considered a separate species.

Optimization and evaluation of a two-stage chromogenic tenase assay for measurement of emicizumab plasma levels

A two-stage chromogenic tenase assay allows specific measurement of emicizumab plasma levels over a broad concentration range (10 µg/ml to 100 µg/ml). The assay showed a reasonable agreement with one-stage clotting assy used for emicizumab quantificaition and can be applied on an automated coagulation analyzer, demonstrating its applicability within a routine laboratory setting.

Safety of ChAdOx1 nCoV-19 vaccination in patients with end-stage renal disease on hemodialysis

This dataset was the minimal dataset of the research article entitle 'Safety of ChAdOx1 nCoV-19 vaccination in patients with end-stage renal disease on hemodialysis'. The study aims to investigate the localized and systemic adverse effects (AEs) within 30-days after the first dose of ChAdOx1 nCoV19 (Oxford-AstraZeneca) vaccination in end-stage renal disease (ESRD) patients receiving hemodialysis (HD). The first dataset is the raw data for logistic regression analyses examining the risk factors in association with AEs, another dataset contains the second- and the seventh- day incidences of various AEs depicted in bar graphs. It comprises variables recording the status of patient-reported local and systemic AEs in questionnaire on the second and seventh days after vaccination as well as patients' baseline demographic and clinical characteristics.

Data from: Petrogenetic studies of Permian pegmatites in the Chinese Altay: implications for a two-stage post-collisional magmatism model

Understanding the petrogenesis of rare-metal pegmatites is important for understanding ore-forming processes and their tectonic settings. In this study, we performed zircon U-Pb geochronological and Hf-O isotopic analyses of the Xiaokalasu (XKLS), Dakalasu (DKLS) and Yelaman (YLM) pegmatites in the Chinese Altay orogen. These pegmatites have low εHf(t) values (-0.6 ~ +4.3), two-stage model ages of 989 ~ 1293 Ma, and high δ18O values (+6.52 ~ +11.31), indicating that they may have been derived from the anatexis of mature sedimentary rocks in the deep crust, with a small amount of mantle-derived or juvenile material. Geochronological and Hf-O isotopic data for granitic intrusions in the Chinese Altay Mountains indicate that the εHf(t) values decreased from the Permian to the Triassic, which implies that two-stage post-collisional magmatism occurred in this region. During the Permian, the thin lower crust was cold; thus, magmatism likely originated in the deep crust close to the Moho surface and involved intense mantle-crust interactions. During the Triassic, asthenospheric upwelling provided heat to the lower crust, which increased the geothermal gradient and led to the anatexis of shallow crustal material.

Data from: Proteomic fingerprinting enables quantitative biodiversity assessments of species and ontogenetic stages in Calanus congeners (Copepoda, Crustacea) from the Arctic Ocean

Species identification is pivotal in biodiversity assessments, and proteomic fingerprinting by MALDI-TOF mass spectrometry has already been shown to reliably identify calanoid copepods to species level. However, MALDI-TOF data may contain more information beyond mere species identification. In this study, we investigated different ontogenetic stages (copepodids C1-C6 females) of three co-occurring Calanus species from the Arctic Fram Strait, which cannot be identified to species level based on morphological characters alone. Differentiation of the three species based on mass spectrometry data was without any error. In addition, a clear stage-specific signal was detected in all species, supported by clustering approaches as well as machine learning using Random Forest. More complex mass spectra in later ontogenetic stages as well as relative intensities of certain mass peaks were found as the main drivers of stage distinction in these species. Through a dilution series, we were able to show that this did not result from the higher amount of biomass that was used in tissue processing of the larger stages. Finally, the data were tested in a simulation for application in a real biodiversity assessment by using Random Forest for stage classification of specimens absent from the training data. This resulted in a successful stage-identification rate of almost 90%, making proteomic fingerprinting a promising tool to investigate polewards shifts of Atlantic Calanus species and, in general, to assess stage compositions in biodiversity assessments of Calanoida, which can be notoriously difficult using conventional identification methods.
