Evidence of declines in insect populations has recently received considerable scientific and societal attention. However, the lack long-term monitoring makes it difficult to assess whether are geographically widespread. By contrast, bird well monitored often used as indicators environmental change. We compared population trends European insectivorous birds with those other patterns were consistent insects. further examined evident for insectivores different habitats, foraging strata,...
Previous studies have reported that chromosome synteny in Lepidoptera has been well conserved, yet the number of haploid chromosomes varies widely from 5 to 223. Here we report genome (393 Mb) Glanville fritillary butterfly (Melitaea cinxia; Nymphalidae), a recognized model species metapopulation biology and eco-evolutionary research, which putative ancestral karyotype n=31. Using phylogenetic analyses Nymphalidae other Lepidoptera, combined with orthologue-level comparisons chromosomes,...
Four collaborations, ANTARES, IceCube, LIGO, and Virgo, join forces to report the non-observation of neutrino events correlated with GW150914 gravitational wave event reported recently by LIGO. Although paper reports a negative result, it both sets important constraints on production in binary coalescence marks significant step multimessenger astronomy.
Seasonal plasticity is accomplished via tightly regulated developmental cascades that translate environmental cues into trait changes. Little known about how alternative splicing and other posttranscriptional molecular mechanisms contribute to or these impact evolves. Here, we use transcriptomic genomic data from the butterfly Bicyclus anynana, a model system for seasonal plasticity, compare extent of differential expression test axes transcriptional differ in their potential evolutionary...
This study investigates the genetic diversity, population structure and demographic history of afrotropical butterfly Bicyclus anynana using mitochondrial DNA (mtDNA). Samples from six wild populations covering most species range Uganda to South Africa were compared for cytochrome c oxidase subunit gene (COI). Molecular diversity indices show overall high mtDNA populations, but low nucleotide divergence between haplotypes. Our results indicate relatively little geographic among southern...
Polyphenisms—the expression of discrete phenotypic morphs in response to environmental variation—are examples plasticity that may potentially be adaptive the face predictable heterogeneity. In butterfly Bicyclus anynana , we examine hormonal regulation involves divergent developmental trajectories into distinct adult for a suite traits as an adaptation contrasting seasonal environments. This polyphenism is induced by temperature during development and mediated ecdysteroid hormones. We reared...
A search for cosmic neutrino sources using the data collected with ANTARES telescope between early 2007 and end of 2015 is performed. For first time, all interactions---charged- neutral-current interactions flavors---are considered in a point-like detector. In previous analyses, only muon charged-current were used. This achieved by novel reconstruction algorithm shower-like events addition to standard track reconstruction. The shower channel contributes about 23% signal an...
Nature has devised many ways of producing males and females. Here, we report on a previously undescribed mechanism for Lepidoptera that functions without female-specific gene. The number alleles or allele heterozygosity in single Z-linked gene ( BaMasc ) is the primary sex-determining switch Bicyclus anynana butterflies. Embryos carrying develop into WZ (or Z0) females, those two distinct ZZ males, while (ZZ) homozygotes initiate female development, have mismatched dosage compensation, die...
The Advanced LIGO observatories detected gravitational waves from two binary black hole mergers during their first observation run (O1). We present a high-energy neutrino follow-up search for the second wave event, GW151226, as well candidate LVT151012. find and four candidates by IceCube, one zero Antares, within $\ifmmode\pm\else\textpm\fi{}500\text{ }\text{ }\mathrm{s}$ around respective signals, consistent with expected background rate. None of these are found to be directionally...

A small number of free-living viruses have been found to be obligately vertically transmitted, but it remains uncertain how widespread transmitted are and quickly they can spread through host populations. Recent metagenomic studies several insects infected with sigma ( Rhabdoviridae ). Here, we report that infect Mediterranean fruit flies Ceratitis capitata ), Drosophila immigrans , speckled wood butterflies Pararge aegeria ) all transmitted. We find patterns vertical transmission consistent...

Abstract For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question high-energy astrophysics. One approach for solving this puzzle is to correlate UHECRs with neutrinos, since neutrinos are a direct probe hadronic interactions and not deflected by magnetic fields. In paper, we present three different approaches correlating arrival directions UHECRs. The neutrino data provided IceCube Neutrino Observatory ANTARES, while UHECR energies above ∼50 EeV...
Abstract Anthropogenic factors have impacted the diversity and evolutionary trajectory of various species. This can be through such as pressure on population size or range, habitat fragmentation, extensive manipulation translocation. Here we use time-calibrated data to better understand pattern processes evolution in heavily manipulated European fallow deer ( Dama dama ). During Pleistocene, had a broad distribution across Europe were found far north Britain during Eemian interglacial. The...
Astrophysical sources of gravitational waves, such as binary neutron star and black hole mergers or core-collapse supernovae, can drive relativistic outflows, giving rise to non-thermal high-energy emission. High-energy neutrinos are signatures outflows. The detection waves from common could help establish the connection between dynamics progenitor properties outflow. We searched for associated emission astrophysical transients with minimal assumptions using data Advanced LIGO its first...

We have determined the location, in three dimensions, of eight quasi‐stable coronal “streamers” from an analysis Solar and Heliospheric Observatory (SOHO) Large‐Angle Spectrometric Coronagraph images acquired over approximately one solar rotation. use locations to attempt determine origin streamers. Comparison streamers' (longitude latitude at R ≈ 2.5 s source surface) with that current sheet computed a potential surface model show all streamers lie or near heliospheric sheet. assume...
Predispersal characteristics that affect the reproductive success in plants may influence their colonizing ability. We evaluated this hypothesis two sympatric epiphytic bromeliads Costa Rica, Guzmania monostachia and Tillandsia fasciculata, show contrasting levels of local seedling recruitment. Genets G. monostachia, species with higher recruitment, reach stage faster because a growth rate (6 vs. 13 yr). In addition, established genets, new asexual ramets develop reproduce annually, whereas...
Abstract Fitness‐related life history traits often show substantial heritable genetic variation in natural populations, but knowledge of the architecture these is limited. In G lanville fritillary butterfly, we measured heritability key a large outdoor population cage during 2 years and generations combined this experiment with an association study set candidate genes. The genes were selected on basis previous genomic transcriptomic studies have been linked to physiology or other arthropod...
Thermal tolerance has a major effect on individual fitness and species distributions can be determined by genetic variation phenotypic plasticity. We investigate the effects of developmental adult thermal conditions cold tolerance, measured as chill coma recovery (CCR) time, during early late stage in Glanville fritillary butterfly. also basis associating CCR with polymorphisms candidate genes that have known role insect physiology. Our results demonstrate cooler temperature leads to reduced...
