Plasmid- and strain-specific factors drive variation in ESBL-plasmid spread in vitro and in vivo

Fabienne Benz
Horizontal gene transfer, mediated by conjugative plasmids, is a major driver of the global rise of antibiotic resistance. However, the relative contributions of factors that underlie the spread of plasmids and their roles in conjugation in vivo are unclear. To address this, we investigated the spread of clinical Extended Spectrum Beta-Lactamase (ESBL)-producing plasmids in the absence of antibiotics in vitro and in the mouse intestine. We hypothesised that plasmid properties would be the primary determinants...

Climate change exposes ecosystems to strong and rapid changes in their environmental boundary conditions mainly due to the altered temperature and precipitation patterns. It is still poorly understood how fast interlinked ecosystem processes respond to altered environmental conditions, if these responses occur gradually or suddenly when thresholds are exceeded, and if the patterns of the responses will reach a stable state. We conducted an irrigation experiment in the Pfynwald, Switzerland from 2003-2018. A naturally dry...

Species interactions drive the spread of ampicillin resistance in human-associated gut microbiota

Siobhan O'Brien, Michael Baumgartner & Alex Hall
Background and objectives Slowing the spread of antimicrobial resistance is urgent if we are to continue treating infectious diseases successfully. There is increasing evidence microbial interactions between and within species are significant drivers of resistance. On one hand, cross-protection by resistant genotypes can shelter susceptible microbes from the adverse effects of antibiotics, reducing the advantage of resistance. On the other hand, antibiotic-mediated killing of susceptible genotypes can alleviate competition and allow resistant strains to thrive...

Conservation of Birds in Fragmented Landscapes Requires Protected Areas

Robert Timmers, Marijke Van Kuijk, Pita Verweij, Jaboury Ghazoul, Yann Hautier, William Laurance, Stefan Arriaga-Weiss, Robert Askins, Corrado Battisti, Åke Berg, Gretchen Daily, Cristián Estades, Beatrice Frank, Reiko Kurosawa, Rosamund Pojar, John Woinarski & Merel Soons
For successful conservation of biodiversity, it is vital to know whether protected areas in increasingly fragmented landscapes effectively conserve species. However, how large habitat fragments must be and what level of protection is required to sustain species, remains poorly known. We compiled a global dataset on almost 2000 bird species in 741 forest fragments varying in size and protection status, and show that protection is associated with higher bird occurrence, especially for threatened species. Protection...

Quantitative trait locus analysis of parasitoid counteradaptation to symbiont-conferred resistance

Gabriel F. Ulrich, Niklaus Zemp, Christoph Vorburger & Hélène Boulain
Insect hosts and parasitoids are engaged in an intense struggle of antagonistic coevolution. Infection with heritable bacterial endosymbionts can substantially increase the resistance of aphids to parasitoid wasps, which exerts selection on parasitoids to overcome this symbiont-conferred protection (counteradaptation). Experimental evolution in the laboratory has produced counteradapted populations of the parasitoid wasp Lysiphlebus fabarum. These populations can parasitize black bean aphids (Aphis fabae) protected by the bacterial endosymbiont Hamiltonella defensa, which confers high resistance against...

Hidden paths to endless forms most wonderful: Parasite-blind diversification of host quality

Lisa Freund, Marie Vasse & Gregory J. Velicer
Evolutionary diversification can occur in allopatry or sympatry, can be driven by selection or unselected, and can be phenotypically manifested immediately or remain latent until realised in a newly encountered environment. Diversification of host-parasite interactions is frequently studied in the context of intrinsically selective coevolution, but the potential for host-parasite interaction phenotypes to diversify latently during parasite-blind host evolution is rarely considered. Here we use a social bacterium experimentally adapted to several environments in the...

Competition and geography underlie speciation and morphological evolution in Indo-Australasian monitor lizards

Carlos J. Pavón-Vázquez, Ian G. Brennan, Alexander Skeels & J. Scott Keogh
How biotic and abiotic factors act together to shape biological diversity is a major question in evolutionary biology. The recent availability of large datasets and development of new methodological approaches provide new tools to evaluate the predicted effects of ecological interactions and geography on lineage diversification and phenotypic evolution. Here, we use a near complete phylogenomic-scale phylogeny and a comprehensive morphological dataset comprising more than a thousand specimens to assess the role of biotic and...

Data from: Facilitation and biodiversity jointly drive mutualistic networks

Gianalberto Losapio, Elizabeth Norton Hasday, Xavier Espadaler, Christoph Germann, Francisco Javier Ortiz-Sánchez, Adrian Pont, Daniele Sommaggio & Christian Schöb
1. Facilitation by nurse plants increases understorey diversity and supports ecological communities. In turn, biodiversity shapes ecological networks and enhances ecosystem functioning. However, whether and how facilitation and increased biodiversity jointly influence community structure and ecosystem functioning remains unclear. 2. We performed a field experiment disentangling the relative contribution of nurse plants and increasing understorey plant diversity in driving pollination interactions. Both the presence of nurse shrubs as well as increased understorey plant diversity increased...

Biodiversity facets, canopy structure and surface temperature of grassland communities

Claudia Regina Guimaraes-Steinicke, Alexandra Weigelt, Raphaël Prouxl, Thomas Lanners, Nico Eisenhauer, Joaquín Duque-Lazo, Björn Reu, Christiane Roscher, Cameron Wagg, Nina Buchmann & Christian Wirth
Canopy structure is an important driver of the energy budget of the grassland ecosystem and is, at the same time, altered by plant diversity. Diverse plant communities typically have taller and more densely packed canopies than less diverse communities. With this, they absorb more radiation, have a higher transpiring leaf surface, and are better coupled to the atmosphere which leads to cooler canopy surfaces. However, whether plant diversity generally translates into a cooling potential remains...

Evolutionary tradeoffs between male secondary sexual traits revealed by a phylogeny of the hyperdiverse tribe Eumaeini (Lepidoptera: Lycaenidae)

Wendy A. Valencia-Montoya, Tiago B. Quental, João Filipe R. Tonini, Gerard Talavera, James D. Crall, Gerardo Lamas, Robert C. Busby, Ana Paula S. Carvalho, Ana B. Morais, Nicolás Oliveira Mega, Helena Piccoli Romanowski, Marjorie A. Liénard, Shayla Salzman, Melissa R. L. Whitaker, Akito Y. Kawahara, David J. Lohman, Robert K. Robbins & Naomi E. Pierce
Male butterflies in the hyperdiverse tribe Eumaeini possess an unusually complex and diverse repertoire of secondary sexual characteristics involved in pheromone production and dissemination. Maintaining multiple sexually selected traits is likely to be metabolically costly, potentially resulting in trade-offs in the evolution of male signals. However, a phylogenetic framework to test hypotheses regarding the evolution and maintenance of male sexual traits in Eumaeini has been lacking. Here, we infer a comprehensive, time-calibrated phylogeny from 379...

Novel integrative modeling of molecules and morphology across evolutionary timescales

Huw A. Ogilvie, Fábio K. Mendes, Timothy G. Vaughan, Nicholas J. Matzke, Tanja Stadler, David Welch & Alexei J. Drummond
Evolutionary models account for either population or species-level processes, but usually not both. We introduce a new model, the FBD-MSC, which makes it possible for the first time to integrate both the genealogical and fossilization phenomena, by means of the multispecies coalescent (MSC) and the fossilized birth-death (FBD) processes. Using this model, we reconstruct the phylogeny representing all extant and many fossil Caninae, recovering both the relative and absolute time of speciation events. We quantify...

Data from: Identifying extracellular vesicles from single cells

Petra Dittrich, Jonas Nikoloff, André Kling & Mario Saucedo-Espinosa
Extracellular vesicles (EVs) are constantly secreted from both eukaryotic and prokaryotic cells. EVs, including those referred to as exosomes, may have an impact on cell signaling and an incidence in diseased cells. In this manuscript, a platform to capture, quantify, and phenotypically classify the EVs secreted from single cells is introduced. Microfluidic chambers of about 300 pL are employed to trap and isolate individual cells. The EVs secreted within these chambers are then captured by...

DATASET: Forecast made on January 11, 2021 for the second Covid-19 wave based on the improved SIR model with a constant ratio of recovery to infection rate

Martin Kröger & Reinhard Schlickeiser
The temporal evolution of second and subsequent waves of the Covid-19 pandemic is investigated. Analytic expressions for the peak time and asymptotic behaviors, early doubling time, late half decay time, and a half-early peak law, characterizing the dynamical evolution of number of cases and fatalities are derived, where the pandemic evolution exhibiting multiple waves is described by the semi-time SIR model. The asymmetry of the epidemic wave and its exponential tail are affected by the...

Data from: Traits mediate niches and co-occurrences of forest beetles in ways that differ among bioclimatic regions

Aim To investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e., their niches), (2) whether these same traits could predict co-occurrence patterns, and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Methods We complied capture records...

Data from: Horizontal Transmission of the Heritable Protective Endosymbiont Hamiltonella defensa Depends on Titre and Haplotype

Heidi Kaech & Christoph Vorburger
Secondary endosymbionts of aphids have an important ecological and evolutionary impact on their host, as they provide resistance to natural enemies but also reduce the host’s lifespan and reproduction. While secondary symbionts of aphids are faithfully transmitted from mother to offspring, they also have some capacity to be transmitted horizontally between aphids. Here we explore whether 11 isolates from 3 haplotypes of the secondary endosymbiont Hamiltonella defensa differ in their capacity for horizontal transmission. These...

Microsatellite data of Vincetoxicum hirundinaria offspring and their inferred mother plants from 13 populations in the South-Western Finnish Archipelago

Anne Muola, J. F. Scheepens, Liisa Laukkanen, Aino Kalske, Pia Mutikainen & Roosa Leimu
Fragmented landscapes may have implications for the genetic structure of populations and for the microevolution of plant species. In particular, landscape fragmentation and/or population isolation might affect the evolution of plant mating systems. Here, we study the consequences of landscape fragmentation on the genetic structure of populations of a perennial herb, Vincetoxicum hirundinaria with a mixed mating system. Our study area, the south-western Finnish archipelago, was formed after the glacial ice sheet started to retreat...

Species ecology explains the various spatial components of genetic diversity in tropical reef fishes

Giulia Francesca Azzurra Donati, Niklaus Zemp, Stéphanie Manel, Maude Poirier, Thomas Claverie, Franck Ferraton, Théo Gaboriau, Rodney Govinden, Oskar Hagen, Shameel Ibrahim, David Mouillot, Julien Leblond, Pagu Julius, Laure Velez, Irthisham Zareer, Adam Ziyad, Fabien Leprieur, Camille Albouy & Loïc Pellissier
Generating genomic data for 19 tropical reef fish species of the Western Indian Ocean, we investigate how species ecology influences genetic diver- sity patterns from local to regional scales. We distinguish between the α, β and γ components of genetic diversity, which we subsequently link to six ecological traits. We find that the α and γ components of genetic diversity are strongly correlated so that species with a high total regional genetic diversity display systematically...
