Independent, external validation of clinical prediction rules for the identification of extended-spectrum β-lactamase-producing Enterobacterales, University Hospital Basel, Switzerland, January 2010 to December 2016
Background Algorithms for predicting infection with extended-spectrum β-lactamase-producing Enterobacterales (ESBL-PE) on hospital admission or in patients with bacteraemia have been proposed, aiming to optimise empiric treatment decisions. Aim We sought to confirm external validity and transferability of two published prediction models as well as their integral components. Methods We performed a retrospective case–control study at University Hospital Basel, Switzerland....

High throughput microCT scanning of small specimens: preparation, packing, parameters and post-processing [NEW RESULTS]
High-resolution X-ray microcomputed tomography, or microCT (CT), enables the digital imaging of whole objects in three dimensions. The power of CT to visualise internal features without disarticulation makes it particularly valuable for the study of museum collections, which house millions of physical specimens documenting the spatio-temporal patterns of life. Despite its potential for comparative analyses, most CT studies include limited numbers of museum specimens, due to the challenges of digitising...

Lack of support for Deuterostomia prompts reinterpretation of the first Bilateria. [NEW RESULTS]
The bilaterally symmetric animals (Bilateria) are considered to comprise two monophyletic groups, Protostomia and Deuterostomia. Protostomia contains the Ecdysozoa and the Lophotrochozoa; Deuterostomia contains the Chordata and the Xenambulacraria (Hemichordata, Echinodermata and Xenacoelomorpha). Their names refer to a supposed distinct origin of the mouth (stoma) in the two clades, but these groups have been differentiated by other embryological characters including embryonic cleavage patterns...

Detailed phylogenetic analysis of SARS-CoV-2 reveals latent capacity to bind human ACE2 receptor [NEW RESULTS]
SARS-CoV-2 is a once-in-a-century pandemic, having emerged suddenly as a highly infectious viral pathogen. Previous phylogenetic analyses show its closest known evolutionary relative to be a virus isolated from bats (RaTG13), with a common assumption that SARS-CoV-2 evolved from a zoonotic ancestor via recent genetic changes (likely in the Spike protein receptor binding domain, or RBD) that enabled it to infect humans. We used detailed phylogenetic analysis, ancestral sequence reconstruction, and...

Additive and non-additive epigenetic signatures of hybridisation between fish species with different mating systems [NEW RESULTS]
Hybridisation is a major source of evolutionary innovation. However, several prezygotic and postzygotic factors influence its likelihood and evolutionary outcomes. Differences in mating systems can have a major effect on the extent and direction of hybridisation and introgression. In plants, epigenetic mechanisms help to stabilize hybrid genomes and contribute to reproductive isolation, but the relationship between genetic and epigenetic changes in animal hybrids is unclear. We analysed the extent...

How will cold water fish respond to climate change: rapid and high magnitude phenotypic responses in Arctic charr. [NEW RESULTS]
Phenotypic plasticity is the ability of an organism to express multiple phenotypes in response to the prevailing environmental conditions without genetic change. This response may thus occur to anthropogenic modifications of that environment and may be asymmetric. Arguably, the most significant future anthropogenic modification of the environment is contemporary climate change. We tested the effect of a temperature differential of 4 C on the Arctic charr phenotypic response within a generation, mimicking...

Ecological effects of stress drive bacterial evolvability under sub-inhibitory antibiotic treatments [NEW RESULTS]
Stress is thought to increase mutation rate and thus to accelerate evolution. In the context of antibiotic resistance, sub-inhibitory treatments could then lead to enhanced evolvability, thereby fueling the adaptation of pathogens. Conducting a meta-analysis of published experimental data as well as our own experiments, we found that the increase in mutation rates triggered by antibiotic treatments is often canceled out by reduced population size, resulting in no overall increase in genetic diversity....

Convergence in light transmission properties of transparent wing areas in clearwing mimetic butterflies [NEW RESULTS]
Mullerian mimicry is a positive interspecific interaction, whereby co-occurring defended prey species share a common aposematic signal that advertises their defences to predators. In Lepidoptera, aposematic species typically harbour conspicuous opaque wing colour pattern, which have convergent optical properties, as perceived by predators. Surprisingly, some aposematic mimetic species have partially or totally transparent wings, which raises the question of whether optical properties of such transparent...

Cis-regulatory evolution spotlights species differences in the adaptive potential of gene expression plasticity [NEW RESULTS]
Phenotypic plasticity is the variation in phenotype that a single genotype can produce in different environments and, as such, is an important component of individual fitness. However, whether the effect of new mutations, and hence evolution, depends on the direction of plasticity remains controversial. Here, we identify the cis-acting modifications that have reshaped gene expression in response to dehydration stress in three Arabidopsis species. Our study shows that the direction of effects of most...

More than meets the eye: syntopic and morphologically similar mangrove killifish species show different mating systems and patterns of genetic structure along the Brazilian coast [NEW RESULTS]
Different mating systems can strongly affect the extent of genetic diversity and population structure among species. Given the increased effects of genetic drift on reduced population size, theory predicts that species undergoing self-fertilization should have greater population structure than outcrossed species, however demographic dynamics may affect this scenario. The mangrove killifish clade is composed of the two only known examples of self-fertilising species among vertebrates (Kryptolebias...

Drastic shift in flowering phenology, an instant reproductive isolation mechanism, explains the population structure of Imperata cylindrica in Japan [NEW RESULTS]
Reproductive isolation plays an important role in population differentiation and speciation, thus enhancing biodiversity in wild plants. Hybridisation sometimes involves rapid reproductive isolation between parents and their hybrids through the novel traits of hybrids derived from a new combination of genomes. Here, we report how a hybrids' new phenotype contributes to rapid reproductive isolation between two ecotypes of Imperata cylindrica. The two ecotypes differ in their flowering phenology and...

Neural divergence and hybrid disruption between ecologically isolated Heliconius butterflies [NEW RESULTS]
The importance of behavioural evolution during speciation is well established, but we know little about how this is manifest in sensory and neural systems. Although a handful of studies have linked specific neural changes to divergence in host or mate preferences associated with speciation, how brains respond to broad environmental transitions, and whether this contributes to reproductive isolation, remains unknown. Here, we examine divergence in brain morphology and neural gene expression between...

Molecular Evolution of SARS-CoV-2 Structural Genes: Evidence of Positive Selection in Spike Glycoprotein [NEW RESULTS]
SARS-CoV-2 caused a global pandemic in early 2020 and has resulted in more than 8,000,000 infections as well as 430,000 deaths in the world so far. Four structural proteins, envelope (E), membrane (M), nucleocapsid (N) and spike (S) glycoprotein, play a key role in controlling the entry into human cells and virion assembly of SARS-CoV-2. However, how these genes evolve during its human to human transmission is largely unknown. In this study, we screened and analyzed roughly 3090 SARS-CoV-2 isolates...

Here, we present an alternative representation of genetic variation that reveals the relative abundance of different allele frequency patterns across populations. Applied to human data, this approach allows viewers to easily see several key features of human genetic variation: (1) most variants are rare and geographically localized, (2) variants that are common in any single region are likely to be shared...

Organogenesis and Vasculature of Anaxagorea and its Implications in the Integrated Axial-Foliar Origin of the Angiosperm Carpel [NEW RESULTS]
The carpel is the definitive structure of angiosperms and the origin of the carpel is of great significance to the phylogenetic origin of angiosperms. The traditional view has been that angiosperm carpels emerged from structures similar to macrosporophylls of pteridosperms or Bennettitales, which bear ovules on the surface of foliar organs. Conversely, according to other perspectives, carpels originated from foliar appendages enclosing the ovule-bearing axis. One of the key distinctions between the...

Developmental models reveal the role of phenotypic plasticity in explaining genetic evolvability [NEW RESULTS]
Biological evolution exhibits an extraordinary capability to adapt organisms to their environments. The explanation for this often takes for granted that random genetic variation produces at least some beneficial phenotypic variation for natural selection to act on. Such genetic evolvability could itself be a product of evolution, but it is widely acknowledged that the immediate selective gains of evolvability are small on short timescales. So how do biological systems come to exhibit such extraordinary...
