Biogeographic differences in plant-soil biota relationships contribute to the invasion exotic range expansion of Verbascum thapsus

Julia Dieskau, Helge Bruelheide, Alexandra Erfmeier & Jessica Gutknecht
Exotic plant species can evolve adaptations to environmental conditions in the exotic range. Furthermore, soil biota can foster exotic spread in the absence of negative soil pathogen-plant interactions or because of increased positive soil biota-plant feedbacks in the exotic range. Little is known, however, about the evolutionary dimension of plant-soil biota interactions when comparing native and introduced ranges. To assess the role of soil microbes for rapid evolution in plant invasion, we subjected Verbascum thapsus,...

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Drought sensitivity of Empetrum nigrum shrub growth at the species’ southern lowland distribution range margin

Stef Weijers, Nils Hein, Julia Merkelbach & Katharina Zech
The ongoing warming of the Earth’s atmosphere is projected to cause a northward shift of species’ distributions, as they track their climatic optimum. In the rapidly warming Arctic, this has already led to an increase of shrubs in tundra ecosystems. While this northern expansion of woody biomass has been studied relatively extensively over the last decade, little research has been devoted to shrub growth responses at the southern margins of Northern Hemisphere shrubs. Here, we...

Delayed color maturation of a sexual ornament in males of a damselfly: crypsis, female mimicry or both?

Rodrigo Cezário, Eralci Therezio, Alexandre Marletta, Stanislav Gorb & Rhainer Guillermo-Ferreira
Dynamic signals are a widespread phenomenon in several taxa, usually associated with intraspecific communication. On the other hand, dynamic iridescent signals are only detectable at specific angles of illumination; hence, the animal can hide the signal to avoid detection when necessary. This structural coloration is mostly dependent on illumination, contrast against the background and the vision of the receiver. Complex behavioural displays may be coupled with structural coloration to create dynamic visual signals that enhance...

Data from: Stiffness gradients facilitate ovipositor bending and spatial probing control in a parasitic wasp

Uroš Cerkvenik, Johan L. Van Leeuwen, Alexander Kovalev, Stanislav N. Gorb, Yoko Matsumura & Sander W. S. Gussekloo
Many parasitic wasps use slender and steerable ovipositors to lay eggs in hosts hidden in substrates, but it is currently unknown how steering is achieved. The ovipositors generally consist of three longitudinally connected elements, one dorsal and two ventral valves that can slide along each other. For the parasitic wasp Diachasmimorpha longicaudata, it has been shown that protraction of the ventral valves causes incurving of the ventral valves towards the dorsal one, which results in...

Data from: The evolution of microendemism in a reef fish (Hypoplectrus maya)

Benjamin M. Moran, Kosmas Hench, Robin S. Waples, Marc P. Höppner, Carole C. Baldwin, W. Owen McMillan & Oscar Puebla
Marine species tend to have extensive distributions, which are commonly attributed to the dispersal potential provided by planktonic larvae and the rarity of absolute barriers to dispersal in the ocean. Under this paradigm, the occurrence of marine microendemism without geographic isolation in species with planktonic larvae poses a dilemma. The recently described Maya hamlet (Hypoplectrus maya, Serranidae) is exactly such a case, being endemic to a 50-km segment of the Mesoamerican Barrier Reef System (MBRS)....

Data from: Data-driven bioregionalization: A seascape-scale study of macrobenthic communities in the Eurasian Arctic

Dmitrii Pantiukhin, Dieter Piepenburg, Miriam L. S. Hansen & Casper Kraan
Aim: We conduct the first model-based assessment of the biogeographical subdivision of Eurasian Arctic seas to (1) delineate spatial distribution and boundaries of macrobenthic communities on a seascape level; (2) assess the significance of environmental drivers of macrobenthic community structures; (3) compare our modelling results to historical biogeographical classifications; and (4) couple the model to climate-change scenarios of environmental changes to project potential shifts in the distribution and composition of macrobenthic communities by 2100. Location:...

Phylogenomic testing of root hypotheses - demonstrative datasets - Opisthokonta and Proteobacteria

Fernando Tria, Tal Dagan & Giddy Landan
The determination of the last common ancestor (LCA) of a group of species plays a vital role in evolutionary theory. Traditionally, an LCA is inferred by the rooting of a fully resolved species tree. From a theoretical perspective, however, inference of the LCA amounts to the reconstruction of just one branch - the root branch - of the true species tree, and should therefore be a much easier task than the full resolution of the...

Dataset: Sanctions and international interaction improve cooperation to avert climate change

Gianluca Grimalda, Alexis Belianin, Heike Hennig-Schmidt, Till Requate & Marina Ryzhkova
Imposing sanctions on non-compliant parties to international agreements is advocated as a remedy for international cooperation failure. Nevertheless, sanctions are costly, and rational choice theory predicts their ineffectiveness in improving cooperation. We test sanctions effectiveness experimentally in international collective-risk social dilemmas simulating efforts to avoid catastrophic climate change. We involve individuals from countries where sanctions were shown to be effective (Germany) or ineffective (Russia) in increasing cooperation. Here we show that, while this result still...

Curie depth points and Geothermal heat flow estimates from spectral analysis of magnetic data in the Transantarctic Mountains and Wilkes Subglacial Basin region.

Maximilian Lowe, Ben Mather, Chris Green, Tom Jordan, Joerg Ebbing & Robert Larter
We present Curie depth point (CDP) and geothermal heat flow (GHF) estimations based on spectral analysis of magnetic airborne data for the Transantarctic Mountains (TAM) and Wilkes Subglacial Basin area. The Curie depth point is defined as the depth at which the Curie Temperature of 580 degC is reached. The Curie Temperature describes the temperature at which magnetic minerals lose their ability to generate a strong magnetic field. We use exclusively high resolution magnetic airborne...

Activity of forest specialist bats decreases towards wind turbines at forest sites

Julia S. Ellerbrok, Anna Delius, Franziska Peter, Nina Farwig & Christian C. Voigt
Worldwide, wind turbines are increasingly being built at forest sites to meet the goals of national climate strategies. Yet, the impact on forest ecosystems and biodiversity is barely understood. Bats may be heavily affected by wind turbines in forests, because many species depend on forest ecosystems for roosting and hunting and can experience high fatality rates at wind turbines. We performed acoustic surveys in 24 temperate forests in the low mountain ranges of Central Germany...

Little is known about the impact of the pandemic on patient care from the perspective of GPs. To gain insight into GPs’ experiences of the COVID-19 pandemic and its impact on patient care in Germany. From August to December 2020, qualitative, semi-structured telephone interviews were conducted with 22 GPs from four randomly selected federal states...

Data from: Temporal variation in antibiotic environments slows down resistance evolution in pathogenic Pseudomonas aeruginosa

Roderich Roemhild, Camilo Barbosa, Robert E. Beardmore, Gunther Jansen & Hinrich Schulenburg
Antibiotic resistance is a growing concern to public health. New treatment strategies may alleviate the situation by slowing down the evolution of resistance. Here, we evaluated sequential treatment protocols using two fully independent laboratory-controlled evolution experiments with the human pathogen Pseudomonas aeruginosa PA14 and two pairs of clinically relevant antibiotics (doripenem/ciprofloxacin and cefsulodin/gentamicin). Our results consistently show that the sequential application of two antibiotics decelerates resistance evolution relative to monotherapy. Sequential treatment enhanced population extinction...

Data from: Association mapping of morphological traits in wild and captive zebra finches: reliable within but not between populations

Ulrich Knief, Holger Schielzeth, Niclas Backstrom, Georg Hemmrich-Stanisak, Michael Wittig, Andre Franke, Simon C. Griffith, Hans Ellegren, Bart Kempenaers & Wolfgang Forstmeier
Identifying causal genetic variants underlying heritable phenotypic variation is a longstanding goal in evolutionary genetics. We previously identified several quantitative trait loci (QTL) for five morphological traits in a captive population of zebra finches (Taeniopygia guttata) by whole-genome linkage mapping. We here follow up on these studies with the aim to narrow down on the quantitative trait variants (QTN) in one wild and three captive populations. First, we performed an association study using 672 single...

Cellular bicarbonate accumulation and vesicular proton transport promote calcification in the sea urchin larva

Marian Hu, Marian Hu, Inga Petersen, William Chang, Christine Blurton & Meike Stumpp
The sea urchin embryo develops a calcitic endoskeleton through intracellular formation of amorphous calcium carbonate (ACC). Intracellular precipitation of ACC, requires HCO3-/CO32- concentrating as well as proton export mechanisms to promote calcification. These processes are of fundamental importance in biological mineralization, but remain largely unexplored. Here we demonstrate that the calcifying primary mesenchyme cells (PMCs) utilize Na+/H+- exchange (NHE) mechanisms to control cellular pH homeostasis during maintenance of the skeleton. During skeleton re-calcification, pHi of...

Data from: Multiple sequence alignment averaging improves phylogeny reconstruction

Haim Ashkenazy, Itamar Sela, Eli Levy Karin, Giddy Landan & Tal Pupko
The classic methodology of inferring a phylogenetic tree from sequence data is composed of two steps. First, a multiple sequence alignment (MSA) is computed. Then, a tree is reconstructed assuming the MSA is correct. Yet, inferred MSAs were shown to be inaccurate and alignment errors reduce tree inference accuracy. It was previously proposed that filtering unreliable alignment regions can increase the accuracy of tree inference. However, it was also demonstrated that the benefit of this...
