Animal Behavior and Reproduction

The paper tests whether male Heliconius butterflies prefer full wing patterns or individual elements, finding no preference difference when elements are removed, suggesting independent function of pattern elements in mating and speciation.

This study links genomic diversity at vgll3 with age-dependent foraging behavior in Atlantic salmon, showing functional connections between diet and life history traits.

This study examines how temperature and food availability interact to influence wing pigmentation in Bicyclus anynana butterflies, showing genotype-specific thermal plasticity and nutritional effects.

The paper investigates whether RNA from Drosophila male seminal fluid is translated by females, identifying 67 male-derived, female-translated proteins and their roles in postmating interactions.

This study shows that corticosterone exposure in wild tree swallows leads to long-term changes in DNA methylation, physiology, and breeding behavior.

This study shows that morphological traits, not socio-cognitive demands, are key predictors of brain size evolution in birds.

The paper identifies pseudo-tail spots in barn swallows as a potential early stage of deceptive ornamentation, with low frequency and slow evolutionary change.

The paper examines gene expression differences in female stickleback brains during mate choice, finding species-specific co-expression patterns linked to male traits and female preferences.

This study examines how rapid body colouration changes in Oryzias celebensis relate to aggressive behavior during male-male competition, finding that blackened markings signal aggression and deter attacks.

This study examines phylogenetic patterns in nest type and other traits of Icteridae birds to assess if they evolved to avoid parasitism by Molothrus species.

This study quantifies phenotypic plasticity and genetic variation in Wahlenbergia ceracea, finding strong plastic responses to growth temperature over parental effects and genetic variation.

This study shows that male fruit flies do not change their diet choice after multiple matings, unlike females, despite physiological costs.

The paper reveals sexual dimorphism in head size among wild burying beetles, showing males have wider heads than females for a given body size, with different scaling relationships between head width and body size.

This paper unifies the detection of sexual selection and assortative mating for discrete and quantitative traits using information theory, showing that the same divergence measure applies to both.

This study investigates the effects of paternal age at conception on male survival, reproductive success, and offspring lifespan in Drosophila, finding no consistent deleterious effects and evidence of viability selection.

The paper shows that metabolic division of labour in burying beetles changes plastically and evolves when post-hatching care is removed, with larvae from populations without care being more successful in carrion consumption and survival.

This study examines factors driving egg morphological diversification in stick and leaf insects, finding that resource allocation and mechanical constraints are key, with egg size linked to female body size and reproductive strategies.

This paper models how maternal care influences the evolution of long, slow life histories in mammals.

The paper investigates the relationship between forceps length and six behavioural and physiological traits in European earwig males, finding no main association between forceps length and the traits measured.

The paper investigates capelin mating strategies, finding that males can regenerate semen, supporting the endurance rivalry hypothesis despite small testes and unique sperm physiology.

This study examines how inbreeding and rearing temperature affect sperm production in guppies, finding that only inbred males increase sperm production in response to female presence, especially when females are outbred.

This study examines how germline maintenance varies with reproductive timing in seed beetles, finding that early-reproducing females show peak maintenance at youth while late-reproducing females exhibit the opposite pattern.

This study examines consistent individual differences in behavior and context-dependent responses in Dendrobates tinctorius poison frogs, finding repeatability in activity and exploration but context-specificity in boldness.

This study experimentally demonstrates that mating effort and ejaculation in mosquitofish have distinct life history trade-offs, challenging the assumption of a shared resource pool for reproductive investment.

This study shows that social environment influences sex-biased aggression in Julidochromis marlieri, with larger fish in pairs being more aggressive and male-larger pairs showing sex-specific responses to intruder sex.

This paper develops a framework to assess social variation in coral gobies across ecological factors, finding that environmental disturbances reduce sociality and group living.

This paper develops methods to evolve visual patterns under wild predator selection using genetic algorithms and demonstrates their feasibility in field experiments with birds.

The paper examines eye morphology divergence between Heliconius species and their hybrids, finding adaptive differences and visual system disruption in hybrids.

The paper uses a spatially explicit model to show spatial structure enables coexistence of alternative reproductive tactics in tree crickets by equalizing mating benefits.

This study investigates how sperm size affects post-mating success in the flatworm Macrostomum lignano, finding that intermediate sperm size provides the highest competitiveness.
