Animal Behavior and Reproduction

The paper tests if prior predation-risk experience affects antipredator behavior in groups, finding no such effect, but immediate threats do influence behavior similarly across experienced and naive individuals.

This paper systematically reviews drivers of birth phenology in large herbivores, finding strong support for seasonality and predation hypotheses but highlighting gaps in Asian and South/Central American species.

The paper introduces the charisma R package for reproducible color characterization of digital images, demonstrating its utility in analyzing color evolution in birds.

The paper uses an individual-based model to show that competition-induced density-dependent fitness can drive sympatric allochronic divergence in Clunio marinus populations.

This study investigates how predation pressure differs between island and mainland habitats and its relationship with bird plumage conspicuousness using 3D-printed models.

The paper uses GWAS and functional validation in Drosophila to show that body size, SSD, and SSP are controlled by non-overlapping, context-dependent loci called private QTLs.

This paper uses mathematical models to show sexual selection through mate choice can increase or minimally reduce genetic variation in display traits and preferences, resolving the lek paradox.

Relocating a captive naked mole rat colony paused the queen's breeding; two daughters then sequentially became breeders without aggression, ending in peaceful succession.

This study investigates how individuality in Drosophila melanogaster persists across different environmental contexts, finding that behavioral consistency remains in at least one trait despite environmental changes.

This study characterizes post-mating responses in Drosophila hydei, a species lacking Sex-Peptide, showing distinct behavioral and physiological changes compared to Drosophila melanogaster.

The paper shows predator-induced body shape changes in Daphnia lumholtzi persist across multiple unexposed generations, demonstrating non-genetic inheritance of phenotypes.

The paper investigates nest-building behavior in cichlids, finding it involves innate templates and flexible schema with neural correlates in hippocampus-like regions.

The paper examines genetic variation in spider mites, finding that faster-growing genotypes experience more competition but cause stronger reproductive interference.

This paper analyzes directional and disruptive selection on non-plastic traits influencing ontogeny in age- and class-structured populations, showing how developmental and demographic interactions shape evolutionary outcomes.

This study investigates conspecific brood parasitism in barn swallows and finds it rare, challenging previous assumptions and highlighting the need for rigorous genetic validation.

This study examines task specialization and coordination in cooperatively breeding cichlids, finding no consistent division of labour and instead task contagion where individuals follow others in task execution.

This study identifies genomic regions and candidate genes associated with dispersal behavior in Tribolium castaneum using artificial selection and genome-wide association analysis.

The paper investigates why the gobiid fish Trimma marinae is monogamous despite potential for polygyny, finding that males can only care for up to three clutches, leading females to guard mates to monopolize care.

The paper investigates the evolutionary relationship between white eye-rings and diurnal behavior in rodents, finding that WER enhances visual appeal in diurnal species.

This study examines infanticide in sociable weavers and finds no direct reproductive benefits, suggesting indirect fitness benefits may drive the behavior.

The paper explains how male contributions to female-male mutualism can overcome the twofold cost of sex by showing that males enhance the fitness of thelytokous females through fertilization.

The paper investigates the relationship between microbiome composition in guppies and sperm motility traits, finding that skin microbiome diversity correlates with sperm velocity.

The paper examines how environmental conditions affect trait interactions in sea rock-pool mosquitoes, showing that salinity modulates direct carry-over effects through larval size-dependent behavioural plasticity.

This study presents an individual-based model to simulate eco-evolutionary dynamics in partially migratory metapopulations under spatio-seasonal environmental variation, showing how migration can mediate population responses to environmental changes.

The paper examines how variation in beech seed abundance affects yolk fatty acid composition in great tits, finding significant differences in PUFA profiles between years of high and low seed availability.

The paper examines sexual dimorphism in dorsal spot number and yellow surface area in Salamandra salamandra terrestris, finding females have more spots and are blacker than males.

This study examines the relationship between pigmentation pattern diversity, species richness, and geography in coral reef fishes, finding a positive correlation and evidence of rapid phenotypic diversification.

This study identifies genetic factors underlying color and pattern variation in Oophaga pumilio frogs from Bocas del Toro, finding key genes involved in different polymorphisms and evidence of selective sweeps.

The paper compares plasma steroid hormone levels between Afrotropical and Palearctic passerines, finding lower baseline corticosterone and testosterone in tropical species.

This study shows that sulphur-crested cockatoos form stable dominance hierarchies despite dynamic social interactions and open group membership.
