Animal Behavior and Reproduction

This study shows that sexual selection does not modulate population sensitivity to heatwaves but may increase resilience to prolonged bottlenecks in the soil mite Sancassania berlesei.

The paper investigates sex-biased dispersal in two polyandrous Jacana species, finding male-biased dispersal in Northern Jacanas and no bias in Wattled Jacanas, with sexually selected traits linked to philopatry in females.

This study investigates whether Drosophila melanogaster uses kin-based social information to guide oviposition decisions, finding that females prefer substrates associated with kin over those with unrelated conspecifics.

The paper tests if the marginal male hypothesis combined with density-dependent pup survival can explain density differences between pinniped colonies.

This study investigates how diet and the vgll3 gene affect maturation in female Atlantic salmon, finding genetic and environmental interactions influence age at maturity.

This study examines whether reduced nuptial gifts in nonsacculate Opiliones species are compensated by increased behavioural sexual conflict through comparative mating behaviour analysis.

The paper examines mate choice and male strategies in wood tiger moths, finding WW males have higher mating success but Wy females have higher reproductive success.

This study shows female guppies preferentially mate with related males in complex social settings, challenging previous findings on inbreeding avoidance.

This study investigates how environmental and social factors influence coloration and behavior in African cichlids, showing that color morphs are environmentally induced and that blue males outcompete yellow males in contests.

This study investigates whether female post-copulatory preference in Drosophila depends on pre-copulatory choice and post-mating environment, finding no effect of male presence but a link between mating latency and sperm ejection.

The paper uses multivariate coevolutionary analysis to show how life-history traits evolve through modular pathways in amniotes, with distinct tempos across traits and taxa.

The study shows transgenerational epigenetic inheritance in Daphnia exposed to Microcystis leads to reduced survival and growth rates, contradicting the idea that it is generally adaptive.

This study compares decision-making strategies of two cichlid fish species under varying perceptual loads, finding divergence when attribute complexity increases.

The paper tests if social interactions mediate age-related differences in plumage traits and reproductive success in barn swallows, finding no evidence of mediation but associations between age, plumage, and reproductive success.

This study shows that Creobroter gemmata nymphs change body color based on red or green backgrounds, with more pronounced differentiation in early stages.

The study tests social learning in Serin birds, finding 40% could learn from conspecifics, with no sex or age influence but wing length and personality traits not linked to learning ability.

This paper revisits Rensch's Rule, expanding its application beyond sexual size dimorphism to other traits to better understand sexual dimorphism and phenotypic diversity.

This study examines bill dimorphism in male Green Hermits, finding males have sharper, more biomechanically efficient bills for stabbing during territorial combat.

This study reviews and analyzes 57 studies on egg hormones in wild birds, finding near-zero overall effects on maternal and offspring fitness but high heterogeneity.

This study examines how early-life adversity affects adult fitness in wild Soay sheep, finding sex-specific differences in how environmental factors influence lifetime breeding success.

The study examines multilevel selection on social behavior and group structure in wild yellow-bellied marmots, finding strong selection on group structure comparable to individual behavior.

This study investigates reproductive costs in bluefin killifish by manipulating sex ratios and densities, finding that male aggression towards females is highest when males lack rivals.

This study examines whether sexually successful Drosophila melanogaster males sire offspring with greater pathogen resistance, finding context- and sex-dependent relationships that contradict the 'good genes' hypothesis.

This study investigates how nutrition and adult density influence sex-biased dispersal in Drosophila melanogaster, finding that female dispersal is sensitive to protein availability and density-dependent in males.

This study links personality differences to demography in wandering albatrosses by analyzing how boldness affects population dynamics through a hyperstate model.

The paper investigates sexual conflict in Zygogramma bicolorata by examining the effects of mating duration and frequency on female fecundity and survivorship, finding that prolonged mating is detrimental to female fitness.

The paper examines how sexual display behavior in two-spotted goby populations follows consistent sex-specific reaction norms across latitude in response to operational sex ratio.

This study identifies sex-specific behavioral syndromes in anemonefish using novel assays, finding significant sex differences in parental care and aggression.

The paper shows that female-limited color polymorphisms evolve more often in high-density populations at high latitudes and in open landscapes, driven by sexual conflict and ecological factors.

This study proposes that aposematic signals may have evolved through sexual selection, leading to increased predation pressure and the eventual development of anti-predator defenses.
