Species specific plant-mediated effects between herbivores converge at high damage intensity

Jinlong Wan, Jiahui Yi, Zhibin Tao, Zhikun Ren, Evans Otieno, Baoliang Tian, Jianqing Ding, Evan Siemann, Matthias Erb & Wei Huang
Plants are often exposed to multiple herbivores and densities of these attackers (or corresponding damage intensities) generally fluctuate greatly in the field. Plant-mediated interactions vary among herbivore species and with changing feeding intensity, but little is known about how herbivore identity and density interact to determine plant responses and herbivore fitness. Here, we investigated this question using Triadica sebifera (tallow) and its two major specialist insect herbivores, Bikasha collaris (flea beetle) and Heterapoderopsis bicallosicollis (weevil)....

Identification of a novel sex determining chromosome in cichlid fishes that acts as XY or ZW in different lineages

Anna Fiona Feller, Vera Ogi, Ole Seehausen & Joana Isabel Meier
Sex determination systems are highly conserved among most vertebrates with genetic sex determination, but can be variable and evolve rapidly in some. Here, we study sex determination in a clade with exceptionally high sex chromosome turnover rates. We identify the sex determining chromosomes in three interspecific crosses of haplochromine cichlid fishes from Lakes Victoria and Malawi. We find evidence for different sex determiners in each cross. In the Malawi cross and one Victoria cross the...

Acute Radiation Syndrome-related gene expression in irradiated peripheral blood cell populations

Patrick Ostheim, Alan Don Mallawaratchy, Thomas Müller, Simone Schüle, Cornelius Hermann, Tanja Popp, Stefan Eder, Stephanie E. Combs, Matthias Port & Michael Abend
In a nuclear or radiological event, an early diagnostic or prognostic tool is needed to distinguish the worried well from low-exposed and those individuals who may later develop life-threatening hematologic acute radiation syndrome (H-ARS). In previous studies, we identified and validated genes in peripheral blood for this purpose. To gain a deeper understanding and to make methodological improvements, we examined the contribution of the peripheral blood´s cell populations on radiation-induced gene expression changes. EDTA whole...

SimBit: A high performance, flexible and easy-to-use population genetic simulator

Remi Matthey-Doret
SimBit is a general purpose, high performance forward-in-time population genetics simulator. SimBit can simulate a wide variety of selection scenarios (any selection and dominance coefficients variation, any epistatic interaction, any spatial and temporal changes of selection scenario, etc.), demographic scenarios (any changes in patch sizes, migration rates, realistic demography dependent on fecundity, hard vs. soft selection, exponential vs logistic growth, gametic or zygotic dispersion, etc.) and mating systems (cloning and selfing rates, hermaphrodites or males...

Soil chemistry determines whether defensive plant secondary metabolites promote or suppress herbivore growth

Lingfei Hu, Zhenwei Wu, Christelle A.M. Robert, Matthias Erb, Jianming Xu, Xiao Ouyang, Tobias Züst & Adrien Mestrot
Plant secondary (or specialized) metabolites mediate important interactions in both the rhizosphere and the phyllosphere. If and how such compartmentalized functions interact to determine plant-environment interactions is not well understood. Here, we investigated how the dual role of maize benzoxazinoids as leaf defenses and root siderophores shapes the interaction between maize and a major global insect pest, the fall armyworm. We find that benzoxazinoids suppress fall armyworm growth when plants are grown in soils with...

Deletion of the sodium/hydrogen exchanger 6 causes low bone volume in adult mice

Fuster Daniel, Daniela Schnyder, Giuseppe Albano, Patrycja Kucharczyk, Silvia Dolder, Mark Siegrist, Manuel Anderegg, Ganesh Pathare, Willy Hofstetter, Roland Baron & Daniel G. Fuster
The sodium/hydrogen exchanger 6 (NHE6) localizes to recycling endosomes, where it mediates endosomal alkalinization through K+/H+ exchange. Mutations in the SLC9A6 gene encoding NHE6 cause severe X-linked mental retardation, epilepsy, autism and corticobasal degeneration in humans. Patients with SLC9A6 mutations exhibit skeletal malformations, and a previous study suggested a key role of NHE6 in osteoblast-mediated mineralization. The goal of this study was to explore the role of NHE6 in bone homeostasis. To this end, we...

Seasonal and daily movement patterns of an alpine passerine suggest high flexibility in relation to environmental conditions

Arnaud Barras, Felix Liechti & Raphaël Arlettaz
Mountains naturally offer variable habitat conditions, but their biodiversity is currently facing the extra challenge of adapting to rapid environmental shifts that are much more pronounced than in the lowlands. Among adaptive responses, intra- and inter-seasonal movements represent potentially important coping strategies for wildlife that remain largely unexplored. We investigated the seasonal and daily movements of the ring ouzel Turdus torquatus, a European mountain bird species that is declining in many parts of its distribution....

Age- and sex-dependent variation in relatedness corresponds to reproductive skew, territory inheritance and workload in cooperatively breeding cichlids

Dario Josi, Dik Heg, Tomohiro Takeyama, Danielle Bonfils, Dmitry A. Konovalov, Joachim G. Frommen, Masanori Kohda & Michael Taborsky
Kin selection plays a major role in the evolution of cooperative systems. However, many social species exhibit complex within-group relatedness structures, where kin selection alone cannot explain the occurrence of cooperative behaviour. Understanding such social structures is crucial to elucidate the evolution and maintenance of multi-layered cooperative societies. In lamprologine cichlids, intragroup relatedness seems to correlate positively with reproductive skew, suggesting that in this clade dominants tend to provide reproductive concessions to unrelated subordinates to...

Data from: Complex evolution of novel red floral color in Petunia

Andrea Berardi, Korinna Esfeld, Lea Jäggi, Therese Mandel, Gina Cannarozzi & Cris Kuhlemeier
Transitions to a new floral color tend to be genetically simple, almost always involving a few loss-of-function mutations of major phenotypic effect. Here we report on the complex evolution of a novel red floral color in the hummingbird-pollinated Petunia exserta (Solanaceae) from a colorless ancestor. The presence of a red color is remarkable because P. exserta retains a nonfunctional copy of the floral anthocyanin activating MYB transcription factor AN2, and additionally the genus cannot synthesize...

Data for synergistic and antagonistic interactions between Varroa destructor mites and neonicotinoid insecticides in male Apis mellifera honey bees

Geoffrey Williams, Peter Neumann, Lars Straub & Selina Bruckner
Pressures from multiple, sometimes interacting, stressors can have negative consequences to important ecosystem-service providing species like the western honey bee (Apis mellifera). The introduced parasite Varroa destructor and the neonicotinoid class of insecticides each represent important, nearly ubiquitous biotic and abiotic stressors to honey bees, respectively. Previous research demonstrated that they can synergistically interact to negatively affect non-reproductive honey bee female workers, but no data exist on how concurrent exposure may affect reproductive honey bee...

Stakeholder priorities determine the impact of an alien tree invasion on ecosystem multifunctionality

Theo Linders, Urs Schaffner, Tena Alamirew, Eric Allan, Simon Choge, René Eschen, Hailu Shiferaw & Peter Manning
1. While the ecological impact of environmental change drivers, such as alien plant invasions, is relatively well-described, quantitative social-ecological studies detailing how these changes impact multiple ecosystem services, and subsequently stakeholders, are lacking. 2. We used a social-ecological approach to assess how Prosopis juliflora (Prosopis henceforth)¸ an invasive tree, affects the provision of multiple ecosystem services to different stakeholder groups in a degraded East African dryland. We combined plot-based ecological data on the impacts of...

Acute radiation syndrome-related gene expression in irradiated peripheral blood cell populations

Patrick Ostheim, Alan Don Mallawaratchy, Thomas Müller, Simone Schüle, Cornelius Hermann, Tanja Popp, Stefan Eder, Stephanie E. Combs, Matthias Port & Michael Abend
In a nuclear or radiological event, an early diagnostic tool is needed to distinguish the worried well from those individuals who may later develop life-threatenFing hematologic acute radiation syndrome. We examined the contribution of the peripheral blood's cell populations on radiation-induced gene expression (GE) changes. EDTA-whole-blood from six healthy donors was X-irradiated with 0 and 4Gy and T-lymphocytes, B-lymphocytes, NK-cells and granulocytes were separated using immunomagnetic methods. GE were examined in cell populations and whole...

Unconventional Monetary Policy and the Great Recession: Estimating the Macroeconomic Effects of a Spread Compression at the Zero Lower Bound

Christiane Baumeister & Luca Benati
We explore the macroeconomic effects of a compression in the long-term bond yield spread within the context of the Great Recession of 2007-2009 via a time-varying parameter structural VAR model. We identify a ‘pure’ spread shock defined as a shock that leaves the policy rate unchanged, which allows us to characterize the macroeconomic consequences of a decline in the yield spread induced by central banks’ asset purchases within an environment in which the policy rate...

Data from: Including tree spatial extension in the evaluation of neighbourhood competition effects in Bornean rain forest

David Newbery & Peter Stoll
Classical tree neighbourhood models use size variables acting at point distances. In a new approach here, trees were spatially extended as a function of their crown sizes, represented impressionistically as points within crown areas. Extension was accompanied by plasticity in the form of crown removal or relocation under the overlap of taller trees. Root systems were supposedly extended in a similar manner. For the 38 most abundant species in the focal size class (10 -...

Density effects of two hemiparasitic Melampyrum species on grassland plant diversity

Nico Heer, Fabian Klimmek, Yasemin Kurtogullari, Daniel Prati, Nora Simone Rieder & Steffen Boch
Hemiparasitic plants can reduce interspecific competition by parasitizing competitive species or by reducing the density of dominant plants. However, effects of hemiparasites have been suggested to be density dependent and to follow an optimum curve, with the highest diversity values occurring at intermediate hemiparasite densities. As a proof of principle, we tested whether this holds true for the two hemiparasitic species Melampyrum arvense and M. nemorosum. We conducted vegetation surveys in thermophilous fringe communities on...

Association of SNPs in Microtus arvalis and clade infections by TULV-CEN.S and TULV-EST.S

Anton Labutin, Moritz Saxenhofer, Thomas White & Gerald Heckel
The natural host ranges of many viruses are restricted to very specific taxa. Little is known about the molecular barriers between species that lead to the establishment of this restriction or generally prevent virus emergence in new hosts. Here, we identify genomic polymorphisms in a natural rodent host associated with a strong genetic barrier to the transmission of the European Tula orthohantavirus (TULV). We analyzed the very abrupt spatial transition between two major phylogenetic clades...

Analysis of ancestry heterozygosity suggests that hybrid incompatibilities in threespine stickleback are environment-dependent

Ken Thompson, Catherine Peichel, Diana Rennison, Matthew McGee, Arianne Albert, Timothy Vines, Anna Greenwood, Abigail Wark, Yaniv Brandvain, Molly Schumer & Dolph Schluter
Hybrid incompatibilities occur when interactions between opposite-ancestry alleles at different loci reduce the fitness of hybrids. Most work on incompatibilities has focused on those that are 'intrinsic', meaning they affect viability and sterility in the laboratory. Theory predicts that ecological selection can also underlie hybrid incompatibilities, but tests of this hypothesis using sequence data are scarce. In this article, we compiled genetic data for F2 hybrid crosses between divergent populations of threespine stickleback fish (Gasterosteus...

Ecological variation drives morphological differentiation in a highly social vertebrate

Annika Freudiger, Dario Josi, Timo Thünken, Fabian Herder, Jana Flury, David Marques, Michael Taborsky & Joachim Frommen
1. Animals may respond to ecological heterogeneity by genetic differentiation or phenotypic plasticity. Responses of organisms to their ecology can include adaptation at various levels of organization, including morphology, behaviour and social structure. Adaptations at one level might con-strain or enhance adaptations on other levels, which highlights the importance of understanding their interactions. 2. In highly social animals, understanding the influence of ecology on the evolution and maintenance of complex social organization poses an intriguing...

Oxygenated polycyclic aromatic hydrocarbon (OPAH) and polycyclic aromatic hydrocarbon (PAH) concentrations in soils with soil properties: A global data set

Wolfgang Wilcke, Moritz Bigalke, Chong Wei, Yongming Han & Benjamin Musa Bandowe
The hazardous oxygenated polycyclic aromatic hydrocarbons (OPAHs) originate from combustion (primary sources) or post-emission conversion of PAHs (secondary sources). We evaluated the global distribution of up to 15 OPAHs in 195 mineral topsoils from 33 study sites (covering 52°N-47°S, 71°W-118°E), to identify indications of primary or secondary sources of OPAHs. The sums of the (frequently measured 7 and 15) OPAH concentrations correlated with those of the S16EPA-PAHs. The relationship of the S16EPA-PAHs concentrations with the...
