    Palaeontology: Sexual dimorphism in dinosaurs

    Stella A Ludwig, Roy E Smith, Nizar Ibrahim
    Studying fossils from a mass-mortality event reveals evidence for sexual dimorphism and, unusually, equal numbers of males and females in a herd of dinosaurs.

    Femora from an exceptionally large population of coeval ornithomimosaurs yield evidence of sexual dimorphism in extinct theropod dinosaurs

    Romain Pintore, Raphaël Cornette ... Ronan Allain
    Consistent bimodal variations in the femoral morphology of various modern amniotes and a remarkably large herd of coeval fossil non-avian theropods evidences sexual dimorphism in dinosaurs.

    Metabolic consequences of various fruit-based diets in a generalist insect species

    Laure Olazcuaga, Raymonde Baltenweck ... Julien Foucaud
    Metabolomic analyses indicate that diet generalism may stem from a neutral metabolic response to different chemistries, rather than from an accumulation of specific adaptations.

    Endoparasitoid lifestyle promotes endogenization and domestication of dsDNA viruses

    Benjamin Guinet, David Lepetit ... Julien Varaldi
    The propensity to endogenize and domesticate dsDNA viruses depends on lifestyle in Hymenoptera.

    Antagonistic role of the BTB-zinc finger transcription factors Chinmo and Broad-Complex in the juvenile/pupal transition and in growth control

    Sílvia Chafino, Panagiotis Giannios ... Xavier Franch-Marro
    Stage identity and developmental progression in insects is controlled by sequential expression of temporal-specific transcription factors.

    Tradeoffs explain scaling, sex differences, and seasonal oscillations in the remarkable weapons of snapping shrimp (Alpheus spp.)

    Jason P Dinh, SN Patek
    Observational field analyses demonstrate that within a species, variation in animal weapon size corresponds to individual differences in the costs and benefits of weaponry.

    Mutation of vsx genes in zebrafish highlights the robustness of the retinal specification network

    Joaquín Letelier, Lorena Buono ... Juan R Martínez-Morales
    Depletion of vsx genes in zebrafish confirms a conserved role in bipolar cells specification across vertebrates, but do not interfere with the formation of the neural retina domain, which reveal an unexpected robustness of the genetic network sustaining the retina.

    The impact of local genomic properties on the evolutionary fate of genes

    Yuichiro Hara, Shigehiro Kuraku
    The genomic features associated with a gene fate to loss have been retained for approximately 500 million years during evolution, and the genes with these features exhibit restricted expression profiles, leading to the genes being less important.

    Coevolutionary dynamics via adaptive feedback in collective-risk social dilemma game

    Linjie Liu, Xiaojie Chen, Attila Szolnoki
    The two-way coupling between collective actions and risk is essential to avoid the tragedy of the commons.

    Thermal phenotypic plasticity of pre- and post-copulatory male harm buffers sexual conflict in wild Drosophila melanogaster

    Claudia Londoño-Nieto, Roberto García-Roa ... Pau Carazo
    Natural temperature variation across an optimal reproductive range for wild flies (Drosophila melanogaster) modulates the impact of sexual conflict on female fitness via asymmetric effects on pre- and post-copulatory male harm mechanisms.
