The paper examines sex differences in gene expression and alternative splicing in stick insects, finding that splicing variation declines more rapidly than gene expression after the transition to asexuality.

This study investigates tandem repeat (TR) variation in stick insect genomes, finding TR enrichment in high-recombination regions and reduced loads in species with larger population sizes.

The paper quantifies introgression in 4126 ant colonies, finding 23% of species show introgression, more than double previous estimates, and suggests postzygotic barriers constrain it.

The paper tests if Wolbachia induces parthenogenesis in ladybugs by reducing Wolbachia load with antibiotics, showing decreased reproduction in parthenogenetic females.

The paper examines sex-biased gene expression in a sexual and parthenogenetic stick insect, finding early gonadal expression patterns suggesting unresolved sexual antagonism.

The paper traces the evolutionary trajectory from hybridogenesis to parthenogenesis and triploid lineages in stick-insects, showing a stepwise transition driven by genomic changes.

This study examines recombination, X inactivation, and centromere protein dynamics during male meiosis in stick insects, revealing unique patterns compared to Drosophila.

The paper investigates whether dosage compensation and meiotic sex chromosome inactivation persist in parthenogenetic stick insects with relaxed selection, finding both mechanisms are conserved despite the absence of male selection.

This study investigates niche differentiation and adaptation in sympatric sexual and asexual grass thrips species, finding that asexuality correlates with geographic niche variation and local adaptation to host plants.

The study examines whether morphologically distinct Myrmica ant species are reproductively isolated using genetic data, finding high congruence between morphology and genetic lineage.

This study identifies convergent evolution of H4K16ac-mediated dosage compensation in a ZW species and links it to sex-dependent lifespan differences.

This study examines dosage compensation and meiotic sex chromosome inactivation in stick insects, finding that X chromosome expression is dynamically regulated in male tissues during development.

The paper identifies young neo-sex chromosomes in ant crickets and estimates their evolutionary origin and recombination suppression events.

The paper analyzes centromere structure and function in stick insects, revealing a functionally monocentric system with holocentric-like features and chromosome-specific centromeres.

The paper develops a decontamination pipeline to detect and remove contamination in genomic data, revealing rare introgression in Lasius ants.

This paper integrates citizen science data with scientific sampling to model ant community richness, diversity, and abundance across elevation gradients.

The paper re-evaluates reproductive modes in Bacillus stick insects using genomic and field data, confirming hybrid lineage ancestry and genome elimination mechanisms.

The paper systematically analyzes genomic features of 26 parthenogenetic animals and finds that no feature is consistently replicated across transitions to asexuality, suggesting lineage-specific patterns.

The paper presents genome assemblies and analysis of two aphid parasitoid wasps, identifying AT-richness and gene family expansions linked to host interactions and symbiosis.

The paper identifies four CSD candidate regions in Lysiphlebus fabarum, showing they lack homology with the honeybee's CSD gene and suggest a novel molecular mechanism for CSD in Hymenoptera.

The paper shows that asexual reproduction in yeast reduces transposable element loads over time through increased TE excision rates.
