Data from: Genotypic diversity and differentiation among populations of two benthic freshwater diatoms as revealed by microsatellites

Pieter Vanormelingen, Katharine M. Evans, David G. Mann, Stacey Lance, Ann-Eline Debeer, Sofie D'Hondt, Tine Verstraete, Luc De Meester & Wim Vyverman
Given their large population sizes and presumed high dispersal capacity, protists are expected to exhibit homogeneous population structure over large spatial scales. On the other hand, the fragmented and short-lived nature of the lentic freshwater habitats that many protists inhabit promotes strong population differentiation. We used microsatellites in two benthic freshwater diatoms, Eunotia bilunaris ‘robust’ and Sellaphora capitata, sampled from within a pond and connected ponds, through isolated ponds from the same region to western...

Data from: An integrative approach to understanding the evolution and diversity of Copiapoa (Cactaceae), a threatened endemic Chilean genus from the Atacama Desert

Isabel Larridon, Helmut E. Walter, Pablo C. Guerrero, Milén Duarte, Mauricio A. Cisternas, Carol Peña Hernández, Kenneth Bauters, Pieter Asselman, Paul Goetghebeur & Marie-Stéphanie Samain
PREMISE OF THE STUDY: Species of the endemic Chilean cactus genus Copiapoa have cylindrical or (sub)globose stems that are solitary or form (large) clusters and typically yellow flowers. Many species are threatened with extinction. Despite being icons of the Atacama Desert and well loved by cactus enthusiasts, the evolution and diversity of Copiapoa has not yet been studied using a molecular approach. METHODS: Sequence data of three plastid DNA markers (rpl32-trnL, trnH-psbA, ycf1) of 39...

Data from: Epigenetic alterations and decreasing insecticide sensitivity of the Asian tiger mosquito Aedes albopictus

A. Oppold, A. Kreß, J. Vanden Bussche, J. B. Diogo, U. Kuch, J. Oehlmann, M. B. Vandegehuchte, R. Müller, M.B. Vandegehuchte & J.B. Diogo
A range of environmental factors, including chemicals, can affect epigenetic processes in organisms leading to variations in phenotype. Thus, epigenetics displays an important environmentally responsive element. The transgenerational impact of environmental stressors on DNA methylation and phenotype was the focus of this study. The influence of two known DNA methylation-changing agents, the phytoestrogen genistein and the fungicide vinclozolin, on the overall DNA methylation level in the Asian tiger mosquito Aedes albopictus was investigated. The experiment...

Data from: Dispersal constraints for the conservation of the grassland herb Thymus pulegioides L. in a highly fragmented agricultural landscape

An Vanden Broeck, Tobias Ceulemans, Gunter Kathagen, Maurice Hoffmann, Olivier Honnay & Joachim Mergeay
Species-rich grassland communities are one of the most important habitats for biodiversity and of high conservation priority in Europe. Restoration actions are mainly focused on the improvement of abiotic conditions, such as nutrient depletion techniques, and are generally based on the assumption that the target community will re-establish at the restored site when the target species exist in the neighborhood. Information on the contemporary seed-dispersal range is therefore crucial to develop effective conservation measures. Here,...

Data from: Low genetic diversity despite multiple introductions of the invasive plant species Impatiens glandulifera in Europe

Jenny Hagenblad, Jennifer Hülskötter, Kamal Prasad Acharya, Jörg Brunet, Olivier Chabrerie, Sara A. O. Cousins, Pervaiz A. Dar, Martin Diekmann, Pieter De Frenne, Martin Hermy, Aurélien Jamoneau, Annette Kolb, Isgard Lemke, Jan Plue, Zafar A. Reshi & Bente Jessen Graae
Background: Invasive species can be a major threat to native biodiversity and the number of invasive plant species is increasing across the globe. Population genetic studies of invasive species can provide key insights into their invasion history and ensuing evolution, but also for their control. Here we genetically characterise populations of Impatiens glandulifera, an invasive plant in Europe that can have a major impact on native plant communities. We compared populations from the species’ native...

Data from: Persistent inter- and intraspecific gene exchange within a parallel radiation of caterpillar hunter beetles (Calosoma sp.) from the Galápagos

Frederik Hendrickx, Viki Vandomme, Carl Vangestel, Thierry Backeljau, Wouter Dekoninck & Steven M. Van Belleghem
When environmental gradients are repeated on different islands within an archipelago, similar selection pressures may act within each island, resulting in the repeated occurrence of ecologically similar species on each island. The evolution of ecotypes within such radiations may either result from dispersal, that is each ecotype evolved once and dispersed to different islands where it colonized its habitat, or through repeated and parallel speciation within each island. However, it remains poorly understood how gene...

Data from: Experimental evolution reveals high insecticide tolerance in Daphnia inhabiting farmland ponds

Mieke Jansen, Anja Coors, Joost Vanoverbeke, Melissa Schepens, Pim De Voogt, Karel A. C. De Schamphelaere & Luc De Meester
Exposure of non-target populations to agricultural chemicals is an important aspect of global change. We quantified the capacity of natural Daphnia magna populations to locally adapt to insecticide exposure through a selection experiment involving carbaryl exposure and a control. Carbaryl tolerance after selection under carbaryl exposure did not increase significantly compared to the tolerance of the original field populations. However, there was evolution of a decreased tolerance in the control experimental populations compared to the...

Data from: Novel insights into relationships between egg corticosterone and timing of breeding revealed by LC-MS/MS

Tom Rosendahl Larsen, Graham D. Fairhurst, Siegrid De Baere, Siska Croubels, Wendt Müller, Liesbeth De Neve & Luc Lens
Inter- and intra-clutch variation in egg corticosterone (CORT), the major glucocorticoid in birds, may provide insights into how maternal stress levels vary with the timing of breeding and with laying order. Common analytical methods (e.g. immunoassays), however, suffer from cross-reaction with other steroids, leading to potential overestimation of CORT concentrations which can obscure true hormone–environment relationships and complicate among-study comparisons. We here apply a new LC-MS/MS technique, which has recently been shown to avoid the...

Data from: Pre-adapting parasitic phages to a pathogen leads to increased pathogen clearance and lowered resistance evolution with Pseudomonas aeruginosa cystic fibrosis bacterial isolates

Ville-Petri Friman, V-P. Friman, D. Soanes-Brown, P. Sierocinski, A. Buckling, H. K. Johansen, S. Molin & M. Merabishvili
Recent years have seen renewed interest in phage therapy - the use of viruses to specifically kill disease-causing bacteria – because of the alarming rise in antibiotic resistance. However, a major limitation of phage therapy is the ease at with bacteria can evolve resistance to phages. Here we determined if in vitro experimental coevolution can increase the efficiency of phage therapy by limiting the resistance evolution of intermittent and chronic cystic fibrosis Pseudomonas aeruginosa lung...

Data from: Post-fragmentation population structure in a cooperative breeding Afrotropical cloud forest bird: emergence of a source-sink population network

Martin Husemann, Laurence Cousseau, Tom Callens, Erik Matthysen, Carl Vangestel, Caspar Hallmann & Luc Lens
The impact of demographic parameters on the genetic population structure and viability of organisms is a long-standing issue in the study of fragmented populations. Demographic and genetic tools are now readily available to estimate census and effective population sizes and migration and gene flow rates with increasing precision. Here we analysed the demography and genetic population structure over a recent 15-year time span in five remnant populations of Cabanis's greenbul (Phyllastrephus cabanisi), a cooperative breeding...

Data from: Host and parasite life history interplay to yield divergent population genetic structures in two ectoparasites living on the same bat species

Jaap Van Schaik, Daan Dekeukeleire & Gerald Kerth
Host–parasite interactions are ubiquitous in nature. However, how parasite population genetic structure is shaped by the interaction between host and parasite life history remains understudied. Studies comparing multiple parasites infecting a single host can be used to investigate how different parasite life history traits interplay with host behaviour and life history. In this study, we used 10 newly developed microsatellite loci to investigate the genetic structure of a parasitic bat fly (Basilia nana). Its host,...

Data from: Microsatellite analysis of museum specimens reveals historical differences in genetic diversity between declining and more stable Bombus species

Kevin Maebe, Ivan Meeus, Maarten Ganne, Thibaut De Meulemeester, Koos Biesmeijer & Guy Smagghe
Worldwide most pollinators, e.g. bumblebees, are undergoing global declines. Loss of genetic diversity can play an essential role in these observed declines. In this paper, we investigated the level of genetic diversity of seven declining Bombus species and four more stable species with the use of microsatellite loci. Hereto we genotyped a unique collection of museum specimens. Specimens were collected between 1918 and 1926, in 6 provinces of the Netherlands which allowed us to make...

Data from: Selection for costly sexual traits results in a vacant mating niche and male dimorphism

Frederik Hendrickx, Bram Vanthournout & Michael Taborsky
The expected strong directional selection for traits that increase a male's mating ability conflicts with the frequent observation that within species, males may show extreme variation in sexual traits. These male reproductive polymorphisms are usually attributed to direct male-male competition. It is currently unclear, however, how directional selection for sexually selected traits may convert into disruptive selection, and if female preference for elaborate traits may be an alternative mechanism driving the evolution of male polymorphism....

Data from: Light accelerates plant responses to warming

Pieter De Frenne, Francisco Rodríguez-Sánchez, An De Schrijver, David A. Coomes, Martin Hermy, Pieter Vangansbeke & Kris Verheyen
Competition for light has profound effects on plant performance in virtually all terrestrial ecosystems. Nowhere is this more evident than in forests, where trees create environmental heterogeneity that shapes the dynamics of forest-floor communities1,​2,​3. Observational evidence suggests that biotic responses to both anthropogenic global warming and nitrogen pollution may be attenuated by the shading effects of trees and shrubs4,​5,​6,​7,​8,​9. Here we show experimentally that tree shade is slowing down changes in below-canopy communities due to...

Data from: Spatial and spatiotemporal variation in metapopulation structure affects population dynamics in a passively dispersing arthropod

Annelies De Roissart, Shaopeng Wang & Dries Bonte
1. The spatial and temporal variation in the availability of suitable habitat within metapopulations determines colonization–extinction events, regulates local population sizes and eventually affects local population and metapopulation stability. Insights into the impact of such a spatiotemporal variation on the local population and metapopulation dynamics are principally derived from classical metapopulation theory and have not been experimentally validated. 2. By manipulating spatial structure in artificial metapopulations of the spider mite Tetranychus urticae, we test to...

Data from: Serendipitous meta-transcriptomics: the fungal community of Norway spruce (Picea abies)

Nicolas Delhomme, Görel Sundström, Neda Zamani, Henrik Lantz, Yao-Cheng Lin, Torgeir R. Hvidsten, Marc P. Höppner, Patric Jern, Yves Van De Peer, Joakim Lundeberg, Manfred G. Grabherr & Nathaniel R. Street
After performing de novo transcript assembly of >1 billion RNA-Sequencing reads obtained from 22 samples of different Norway spruce (Picea abies) tissues that were not surface sterilized, we found that assembled sequences captured a mix of plant, lichen, and fungal transcripts. The latter were likely expressed by endophytic and epiphytic symbionts, indicating that these organisms were present, alive, and metabolically active. Here, we show that these serendipitously sequenced transcripts need not be considered merely as...

Data from: Molecular variability and genetic structure of Chrysodeixis includens (Lepidoptera: Noctuidae), an important soybean defoliator in Brazil

Janine Palma, Kevin Maebe, Jerson Vanderlei Carús Guedes & Guy Smagghe
This study provides the first genetic characterization of the soybean looper, Chrysodeixis includens (Walker, 1857), an important defoliating pest species of soybean crops in Brazil. Population genetic variability and the genetic structure of C. includens populations were evaluated by using ISSR markers with samples from the major soybean producing regions in Brazil in the growing seasons 2011/2012. Seven different primers were applied for population characterization of the molecular variability and genetic structure of 8 soybean...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Into and out of the tropics: global diversification patterns in a hyper-diverse clade of ectomycorrhizal fungi

Brian P. Looney, Martin Ryberg, Felix Hampe, Marisol Sánchez-García & P. Brandon Matheny
Ectomycorrhizal (ECM) fungi, symbiotic mutualists of many dominant tree and shrub species, exhibit a biogeographic pattern counter to the established latitudinal diversity gradient of most macroflora and fauna. However, an evolutionary basis for this pattern has not been explicitly tested in a diverse lineage. In this study, we reconstructed a mega-phylogeny of a cosmopolitan and hyper-diverse genus of ECM fungi, Russula, sampling from annotated collections and utilizing publically available sequences deposited in GenBank. Metadata from...

Data from: The impact of conservation management on the community composition of multiple organism groups in eutrophic interconnected man-made ponds

Pieter Lemmens, Joachim Mergeay, Jeroen Van Wichelen, Luc De Meester & Steven A. J. Declerck
Ponds throughout the world are subjected to a variety of management measures for purposes of biodiversity conservation. Current conservation efforts typically comprise a combination of multiple measures that directly and indirectly impact a wide range of organism groups. Knowledge of the relative impact of individual measures on different taxonomic groups is important for the development of effective conservation programs. We conducted a field study of 28 man-made ponds, representing four management types differing in the...

Data from: Life-history evolution in response to changes in metapopulation structure in an arthropod herbivore

Annelies De Roissart, Nicky Wybouw, David Renault, Thomas Van Leeuwen & Dries Bonte
The persistence and dynamics of populations largely depends on the way they are configured and integrated into space and the ensuing eco-evolutionary dynamics. We manipulated spatial and temporal variation in patch size in replicated experimental metapopulations of the herbivore mite Tetranychus urticae and followed evolutionary dynamics over approximately 30 generations. A significant divergence in life history traits, physiological endpoints and gene expression was recorded in the spatially and spatiotemporally variable metapopulation, but also a remarkable...

Data from: Nitrous oxide emission by the non-denitrifying, nitrite ammonifier Bacillus licheniformis

Yihua Sun, Paul De Vos & Kim Heylen
Background: Firmicutes have the capacity to remove excess nitrate from the environment via either denitrification, dissimilatory nitrate reduction to ammonium or both. The recent renewed interest in their nitrogen metabolism has revealed many interesting features, the most striking being their wide variety of dissimilatory nitrate reduction pathways. In the present study, nitrous oxide production from Bacillus licheniformis, a ubiquitous Gram-positive, spore-forming species with many industrial applications, is investigated. Results: B. licheniformis has long been considered...

Data from: Patient characteristics associated with tuberculosis treatment default: a cohort study in a high-incidence area of Lima, Peru

Brian Lackey, Carlos Seas, Patrick Van Der Stuyft & Larissa Otero
Background: Although tuberculosis (TB) is usually curable with antibiotics, poor adherence to medication can lead to increased transmission, drug resistance, and death. Prior research has shown several factors to be associated with poor adherence, but this problem remains a substantial barrier to global TB control. We studied patients in a high-incidence district of Lima, Peru to identify factors associated with premature termination of treatment (treatment default). Methods: We conducted a prospective cohort study of adult...

Data from: Hydrodynamic drag constrains head enlargement for mouthbrooding in cichlids

Sam Van Wassenbergh, Nuno Z. Potes & Dominique Adriaens
Presumably as an adaptation for mouthbrooding, many cichlid fish species have evolved a prominent sexual dimorphism in the adult head. Since the head of fishes serves as a bow during locomotion, an evolutionary increase in head volume to brood more eggs can trade-off with the hydrodynamic efficiency of swimming. Here, the differences between males and females in three-dimensional shape and size of the external head surfaces and the effect thereof on drag force during locomotion...

Data from: The first multi-gene phylogeny of the Macrostomorpha sheds light on the evolution of sexual and asexual reproduction in basal Platyhelminthes

Toon Janssen, Dita B. Vizoso, Gregor Schulte, D. Timothy J. Littlewood, Andrea Waeschenbach & Lukas Schärer
The Macrostomorpha—an early branching and species-rich clade of free-living flatworms—is attracting interest because it contains Macrostomum lignano, a versatile model organism increasingly used in evolutionary, developmental, and molecular biology. We elucidate the macrostomorphan molecular phylogeny inferred from both nuclear (18S and 28S rDNA) and mitochondrial (16S rDNA and COI) marker genes from 40 representatives. Although our phylogeny does not recover the Macrostomorpha as a statistically supported monophyletic grouping, it (i) confirms many taxa previously proposed...
