FIG. 1 in Towards Navigating the Minotaur's Labyrinth: Cryptic Diversity and Taxonomic Revision within the Speciose Genus Hipposideros (Hipposideridae)

FIG. 1. Phylogenetic tree inferred from Bayesian analysis in MrBayes from the ca. 3 kb nuclear intron dataset under a fully partitioned model. At each node nodal support is shown as bootstrap support from the RAxML analysis and posterior probabilities from the Bayesian analysis converted to percentages. Black squares denote highly supported nodes with bootstrap values of 100 for the ML analysis and a posterior probability of 1. Filled circles denote African species and open circles denote Asian taxa. '-' indicates that the relationship was not recovered in the ML analysis. See Systematic Summary for full description of the newly elevated genera Macronycteris and Doryrhina. See Table 1 for definitions of acronyms

Fig. 9 in Uncovering cryptic diversity in the enigmatic ant genus Overbeckia and insights into the phylogeny of Camponotini (Hymenoptera:Formicidae:Formicinae)

Fig. 9. Time-calibrated phylogeny of Camponotini including all eight extant genera. The chronogram has been inferred using the fossilised birth–death model with 21 vetted fossil records and the constrained approach (Table 1), where we used a secondary calibration point (normal distribution, M = 51 and S = 5) for the most recent common ancestor of extant Camponotini lineages. The numbers at nodes reflect the posterior probabilities (support values). The generic images placed along the tree were taken for the specimens of the representative species collected in Klimes et al. (2015) or retrieved from AntWeb (Dinomyrmex, Opisthopsis).

Fig. 7. Distribution map of Overbeckia species records. In total, 17 records of the genus are mapped and revised to the species level of which 12 are reported here for the first time (see Results and Supplementary Table S2). Distribution by countries is coloured in pink, with the Singapore record of the types of O. subclavata scaled up to Malaysia. In Indonesia and Queensland, respectively nine and three sites are relatively nearby and hence appear clumped.

Fig. 8. Variation in Overbeckia species occurrence across four vegetation types and two seasons in the EFForTS project (dry season, bars in red; wet season, bars in blue). Values on the y-axis show the number of cases in which the species occurred at least once in a subplot. In total, 19 individuals and 14 occurrences were found across 192 subplots sampled during dry and wet seasons (0.07% occupancy). At the level of different sites (forest plots), only 9 of 32 sampled here by canopy fogging were occupied by the genus.

Fig. 3. Proventriculus of the ant genera Overbeckia (a), Calomyrmex (b), Echinopla (c) and Colobopsis (d). The darker flanges are sepals that are attached anteriorly to the tissues of the ant gut, whereas the convex light structure represents proventricular bulb that connects posteriorly to the stomodeal valve of the worker midgut. Note the posterior connection is broken here due to the removal of the structure from the gut of ant worker. The patterns reflect natural colouring of the structures.

Phylogeography of a widely distributed plant species reveals cryptic genetic lineages with parallel phenotypic responses to warming and drought conditions

To predict how widely distributed species will perform under future climate change it is crucial to understand and reveal their underlying phylogenetics. However, detailed information about plant adaptation and its genetic basis and history remains scarce and especially widely distributed species receive little attention despite their putatively high adaptability. To examine the adaptation potential of a widely distributed species, we sampled the model plant Silene vulgaris across Europe. In a greenhouse experiment, we exposed the offspring of these populations to a climate-change scenario for central Europe and revealed the population structure through whole genome sequencing. Plants were grown under two temperature (18°C, 21°C) and three precipitation regimes (65 mm, 75 mm, 90 mm) to measure their response in biomass and fecundity related traits. To reveal the population genetic structure, ddRAD sequencing was employed for a whole genome approach. We found three major genetic clusters in S. vulgaris from Europe: one cluster comprising Southern European populations, one cluster of Western European populations and another cluster containing Central European populations. Population genetic diversity decreased with increasing latitude and a Mantel test revealed significant correlations between FST and geographic distances as well as between genetic and environmental distances. Our trait analysis showed that the genetic clusters significantly differed in biomass-related traits and in the days to flowering. However, half of the traits showed parallel response patterns to the experimental climate change scenario. Due to the differentiated but parallel response patterns, we assume that phenotypic plasticity plays an important role for the adaptation of the widely distributed species S. vulgaris and its intraspecific genetic lineages.

Data from: Dietary stress unmasks cryptic genetic variation regulating lifespan in outbred Drosophila

Evolutionary theory suggests that lifespan-associated alleles should be purged from the gene pool, and yet decades of GWAS and model organism studies have shown they persist. Here, we address one potential explanation, the idea that the alleles that regulate lifespan do so only in certain contexts. We exposed thousands of outbred Drosophila to a standard and a high sugar diet. We then sequenced over 10,000 individuals and track genome-wide allele frequency changes over time, as these populations aged. We mapped thousands of lifespan-altering alleles, some associated with early- vs late-life tradeoffs, late-onset effects, and genotype-by-environment interactions. We find that lifespan-reducing alleles are most likely to be recently derived and have stronger effects on a high-sugar diet, consistent with the hypothesis that historically neutral or beneficial alleles can become detrimental in novel conditions. We also show that the gene midway, a regulator of lipid storage and ortholog of the lifespan-associated gene DGAT1 in mice, also regulates lifespan in Drosophila. Our results provide insight into the highly polygenic and context-dependent genetic architecture of lifespan, as well as the evolutionary processes that shape this key trait.
