Soil microbial activity and abundance data in the rhizosphere and bulk soils of O horizon in the MELNHE study, 2014
The Multiple Element Limitation in Northern Hardwood Ecosystems (MELNHE) project studies N and P acquisition and limitation through a series of nutrient manipulations in northern hardwood forests. This data set includes rhizosphere processes and microbial abundance at the Bartlett Experimental Forest. Samples were collected once, in summer 2014, in the forth year of fertilization with N and P. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
Soil property, microbial abundance, and plant and invertebrate biomass data across a natural soil temperature gradient in Iceland from August 2018
<p><span>This is a dataset of soil physiochemical properties, bacterial and fungal abundance, and above and belowground plant and invertebrate biomass, sampled at 40 plots in the Hengill geothermal valley, Iceland, from 15<sup>th</sup> to 22<sup>nd</sup> August 2018. The plots span a temperature gradient of 10</span><span>-35 °C over the sampling period, and this temperature gradient is consistent over time. The dataset also includes data on the decomposition rate of soil organic matter, which was sampled at 60 plots in the Hengill valley from May to July 2015.</span></p>
Atlantic salmon (Salmo salar) transfer to seawater by gradual salinity changes exhibited an increase in the intestinal microbial abundance and richness data
<p>The host's physiological history and environment determine the microbiome structure. In that sense, the strategy used for the salmon transfer to seawater after parr-smolt transformation may influence the Atlantic salmon’s intestinal microbiota. Therefore, this study aimed to explore the diversity and abundance of the Atlantic salmon intestinal microbiota and metagenome functional prediction during seawater transfer under three treatments. One group was exposed to gradual salinity change (GSC), the other to salinity shock (SS), and the third was fed with a functional diet (FD) before the seawater (SW) transfer. The microbial profile was assessed through full-16S rRNA gene sequencing using the Nanopore platform. In addition, metagenome functional prediction was performed using PICRUSt2. The results showed an influence of salinity changes on Atlantic salmon gut microbiota richness, diversity, and taxonomic composition. The findings reveal that GSC and the FD increased the Atlantic salmon smolt microbiota diversity, suggesting a positive association between the intestinal microbial community and fish health during seawater transfer. The reported knowledge can be applied to surveil the microbiome in smolt fish production, improving the performance of Atlantic salmon to seawater transfer.</p>

Data from: Genetic identity and herbivory drive the invasion of a common aquatic microbial invader - phytoplankton and zooplankton abundance
<p>Despite the increasing number of species invasions, the factors driving invasiveness are still under debate. This is particularly the case for 'invisible' invasions by aquatic microbial species. Since in many cases only a few individuals or propagules enter a new habitat, their genetic variation is low and might limit their invasion success, known as the genetic bottleneck. Thus, a key question is, how genetic identity and diversity of invading species influences their invasion success and, subsequently, affect the resident community.</p> <p>We conducted invader-addition experiments using genetically different strains of the globally invasive, aquatic cyanobacterium <i>Raphidiopsis raciborskii</i> (formerly: <i>Cylindrospermopsis raciborskii</i>) to determine the role of invader identity and genetic diversity (strain richness) at four levels of herbivory. We tested the invasion success of solitary single strain invasions against the invader genetic diversity, which was experimentally increased up to ten strains (multi-strain populations). By using amplicon sequencing we determined the strain-specific invasion success in the multi-strain treatments and compared those with the success of these strains in the single-strain treatments. Furthermore, we tested for the invasion success under different herbivore pressures.</p> <p>We showed that high grazing pressure by a generalist herbivore prevented invasion, whereas a specialist herbivore enabled coexistence of consumer and invader. We found a weak effect of diversity on invasion success only under highly competitive conditions. When invasions were successful, the magnitude of this success was strain-specific and consistent among invasions performed with single-strain or multi-strain populations. A strain-specific effect was also observed on the resident phytoplankton community composition, highlighting the strong role of invader genetic identity.</p> <p>Our results point to a strong effect of the genetic identity on the invasion success under low predation pressure. The genetic diversity of the invader population, however, had little effect on invasion success in our study, in contrast to most previous findings. Instead, it is the interaction between the consumer abundance and type together with the strain identity of the invader that defined invasion success. This study underlines the importance of strain choice in invasion research and in ecological studies in general.</p>

Relative abundance tables for bacterial species, pathways, ARGs, and VFGs in "Gut Microbial Community Structure, Metabolic Signature, and Resistome in Dyslipidemia: Insights from Metagenomic Sequencing"
<p>Dyslipidemia, characterized by abnormal blood lipid levels, is a significant risk factor for cardiovascular disease. Emerging evidence suggests that the gut microbiota plays a role in lipid metabolism, although findings across studies have varied. In this study, we analyzed the gut microbiota, metabolic pathways, predicted gut metabolites, and resistome in 1384 participants (895 with dyslipidemia cases and 489 controls) using shotgun metagenomic sequencing. Our results revealed that Bacteroides caccae was enriched in dyslipidemia cases, potentially contributing to inflammation and altered lipid metabolism, while Coprococcus eutactus and Coprococcus catus, known producers of short-chain fatty acids (SCFAs) in lipid regulation, and Blautia obeum, known to be positively impacted by SCFAs, were more abundant in controls. We also identified an enrichment of the dTDP-beta-D-fucofuranose biosynthesis pathway gene family, which is linked to bacterial pathogenicity, in dyslipidemia cases, with Bacteroides stercoris contributing strongly. Dyslipidemia cases exhibited depleted glycogen and peptidoglycan biosynthesis pathways, potentially impairing energy storage and immune function, alongside distinct metabolic profiles, including decreased pseudouridine, which may affect RNA metabolism. Furthermore, we observed a higher abundance of antibiotic-resistance genes, particularly tetQ, in dyslipidemia cases, suggesting a link between gut resistome and metabolic disorders. These findings provide new insights into how dysbiosis of the gut microbiota may contribute to the pathophysiology of dyslipidemia, offering potential avenues for microbiome-based interventions in personalized medicine.</p>
