Figure 2 in Waclawiková and others (2025): "Serotonin metabolism protects P. fluorescens from oxidative stress possibly via upregulation of phenylalanine and tyrosine catabolic pathways. A RNA-seq experimental design. B Heat map of the genes that are significantly regulated (at 10 and 12 h) in the presence of serotonin as compared to the untreated control. Data represent log2(fold change). FDR ≤ 0.05, fold change ≥ 2. GSEA analysis of upregulated genes from stimulation with serotonin (FDR ≤ 0.05, fold change ≥ 2) after 10 h and 12 h. Data show -log2(p value) for specific GO biological pathways (bar graphs on the left); number of genes involved in the regulated pathways (bar graphs in the middle); and, expression patterns of individual genes involved in the regulated pathways (graphs on the right). C Volcano plots of differentially abundant proteins after 12 h (left panel) and 24 h (right panel) of stimulation with serotonin in P. fluorescens. D Overview of phenylalanine, tyrosine and arginine catabolic pathway and its regulation by serotonin on the RNA and protein level"

Figure 1 in Dong et al. (2025): "Fecundity schedules (mean number of spiderlings per female produced in each consecutive egg sac) of female Steatoda grossa spiders fed constantly with late instar cricket nymphs (red boxes) or intermittently with mid instar cricket nymphs (blue boxes).

The whiskers extend from the box to the minimum and maximum values within a certain range, and data points beyond whiskers are considered outliers"

Figure 3 in Huang et al. (2025): "Co-occurrence network graphs of microbial taxa (at the genus level) at sampling sites with different vegetation types along an elevation gradient. Each node signifies a genus, colors of the nodes indicate different phyla, while phyla with relative abundance < 1 % are merged as “others” and are shown in grey. The size of each node is proportional to the number of edges (degree). A red edge indicates a positive interaction between two individual nodes, while a blue edge indicates a negative interaction."

Figure 1 in Peso et al. (2025): "Illustration showing different non-mutually exclusive trajectories of community assembly in new habitats: (1) coexistence of early and later arriving species (nestedness), (2) replacement of early by later arriving species (turnover), (3) early species dominance leading to priority effects, and (4) community changes due to environmental change and colonisation by other organism groups. Real-life scenarios may involve a mix of these trajectories."

Figure 3 in Shi et al. (2025): "The survival probability of Gelis agilis females was studied in microcosmos arenas that differed in complexity, and in which provisioning of food and cocoons was (a) temporally or (b) spatially separated. In single dish arenas with 1, 2, 4, 8 or 16 compartments, respectively (a), provisioning of food and cocoons was alternated every 48 h. In two-dish arenas with 1, 4 or 9 compartments, respectively, connected by a tube (b), food was offered in one dish and cocoons in the other. In the two-dish arenas, food and cocoons were replaced every 48 h, but were both provided simultaneously. The dotted lines depict median survival, and the coloured shaded areas represent the 95% confidence interval for the survival curves. The number of replicates is 10 per arena type in (a) and 30 in (b). In (b), the arrows on the x-axis represent the median longevity of females provided only with food and no hosts (experiment 2.2)."

Figure 1 in Van Galen et al. (2025): "The PLFA and enzyme activity database contains 12,258 samples from 3,743 locations. The purple colour gradient shows the degree to which climatic space is represented by the samples (scale of 0 to 1, see Technical Validation section). Grey regions do not have sufficient climate data available to evaluate climatic representation. The histogram and donut plots show number of samples (in parentheses) from the PLFA (blue) and enzyme (red) datasets collected in different years, from different continents, from different biomes43, and within different categories of maximum sample depth. Only large segments of donut plots are labelled. Temp. = temperate."

New publication: Metagenome-based identification of functional traits of the black soldier fly gut microbiome associated with larval performance, by @raaijmakersjm.bsky.social and others. #biodiversity #foodwaste #insectgut
doi.org/10.1186/s128...
Figure 7 in IJdema et al. (2025): "Overview of the biosynthetic gene clusters and Gene Cluster Families. The ovals in the figure represent the contigs extracted from the metagenomics dataset that were identified as secondary metabolite gene clusters (or biosynthetic gene clusters, BGCs) by antiSMASH. The taxonomic identification of each BGC based on a similarity search in GenBank is provided. Next, BGCs from the metagenomics dataset and BGCs from the MIBiG reference database (shown as grey arrowheads) with similar functionalities were clustered together in a network of gene cluster families (GCFs). A total of 16 GCFs were identified and classified per category (non-ribosomal peptide synthetase (NRPS). Ribosomally Synthesised and Post-translationally Modified Peptides (RiPPs). polyketide synthases (PKS) or hybrids between these groups) or placed in the “Other” category. BGCs that belonged to the same GCF are outlined in green. Six GCFs that were of interest in this study were numbered in the figure. The colour of the oval indicates whether the BGCs that were part of the GCF were significantly more present in the black soldier fly metagenome of larvae reared on chicken feed- (CF-LM. blue) or supermarket food waste- (SFW-LM) diet (red)"
