Animal Behavior and Reproduction

The paper tests five ant species in open field scenarios to identify behavioral response profiles and factors influencing their reactions to novel environments.

This study investigates the evolution of leading-edge serrations in swallows, finding they are linked to sperm competition rather than foraging behavior, unlike in owls.

The paper analyzes color evolution across five bird clades, finding that new color mechanisms enable new color space occupancy but not increased diversity, and that interpatch variation diverges from interspecies trends in males.

This study shows that larval competition in Drosophila melanogaster depends on egg number, food volume, and container dimensions, not just density, and introduces effective density as a better metric.

This study shows that Drosophila melanogaster populations adapted to larval crowding better counter age disadvantages in competition than low-density controls, but differences in egg size and hatching time among these populations do not improve their performance against age-disadvantaged competitors.

This study examines the physiological costs of prospecting behavior in Florida scrub-jays, finding that frequent prospecting is linked to oxidative damage but not mass loss.

This study identifies a genetic locus that increases burrow length in deer mice by altering specific digging behaviors.

The paper finds that in guppies, telomere length is negatively correlated with sperm production, suggesting a trade-off between reproduction and maintenance rather than aging.

The paper shows that a regime shift in Atlantic salmon populations led to a plastic response bypassing genetic influences on maturation age, despite unchanged allele frequencies.

This study investigates the heritability of fetal testosterone in wild nutrias, finding sex-specific genetic architecture and low cross-sex genetic correlation.

The paper shows that conserved genetic architecture of behavioral syndromes constrains evolutionary divergence in field crickets across populations.

The paper identifies QTL associated with courtship behavior differences between two Nasonia species and finds polygenic, interactive genetic architecture.

The paper uses mathematical models to compare protective coloration strategies of Taurotragus oryx in different environments, finding that natural selection increases the diversity of quasi-adaptations.

The paper identifies genetic loci, genes, and coexpression modules associated with life history trait variation in Daphnia pulex using genotyping, RNA-Seq, and phenotyping.

The paper identifies 59 behavioral modules linked to economic behavior in foraging mice using machine learning and shows their genetic and parental influences.

The paper shows how adversarial perturbations can create deceptive visual signals in animals, leading to exaggerated color patterns that remain evolutionarily stable.

This study identifies gene expression differences in NMR brain and gonads across reproductive castes, linking dopamine pathways and hyperprolactinaemia to eusocial reproductive suppression.

The paper shows that kinship affects fly fertility through epigenetic mechanisms involving pre- and post-zygotic processes, induced by a methylating cocktail.

The paper describes the phenotypic expression of the Purple Body gene in domestic guppy strains, highlighting its role in modifying coloration and the creation of new phenotypes when combined with other mutant genes.

The paper investigates the transcriptional basis of variation in parental provisioning behavior in burying beetles and finds that quantitative behavioral variation reflects many small transcriptional differences rather than a few major genes.

The paper analyzes reaction norms in Drosophila mediopunctata to disentangle plasticity components and test genetic models, finding support for the Pleiotropy model.
