Animal Behavior and Reproduction

This study examines how fine-scale changes in food distribution and social stability affect sociality in wild great tits, finding that resource clustering increases flock size and social centrality.

The study shows female budgerigars prefer males with foraging skills different from their own, supporting the skill-pool hypothesis in mate choice.

The paper investigates sneaky pesterer reproductive tactics in banded mongooses, finding they are rarely used as a stepping stone but instead as a backup strategy with lower reproductive success.

This study examines pair-bond strength in wild jackdaws, finding it varies across the population, is consistent over time, and linked to socio-cognitive performance, but not directly to fitness outcomes.

This study examines how mating strategies affect life history traits in the alien snail Rumina decollata, finding that self-fertilization leads to higher body weight but lower fecundity and inbreeding depression in offspring.

This study shows that breeding changes female vulturine guineafowl's social status by altering dominance dynamics with both males and non-breeding females.

The paper models the evolution of human pair bonds by simulating male mating strategies under different sex ratio conditions and finds that higher sex ratios favor mate-guarding over multiple mating.

This study shows that increased begging effort, not reduced food intake, causes lower growth in zebra finch nestlings raised in larger broods.

The paper estimates heritability of migration traits in mule deer using GPS and genomic data, finding low heritability for migration timing, distance, and duration but high heritability for movement rate.

This study examines how direct and indirect effects influence agonistic behaviors in house crickets, showing varying impacts on aggression initiation and stridulation traits.

This study shows Aedes aegypti females use multiple conspecific cues to assess competition for oviposition sites, with attraction to low-density cues and avoidance at high densities.

This study examines how parasitism affects sex allocation in hermaphroditic barnacles, finding that parasite infestation reduces reproductive investment and shifts sex allocation towards males in heavily infested hosts.

The paper describes agonistic behavioral sequences in wild slender mudskippers, finding that larger individuals win more often and winners display more aggressive behaviors than losers.

The paper examines how parental care affects the relationship between early-life size, growth, and glucose metabolism in nestling barn swallows, finding that lower parental care intensifies the physiological disadvantage of being smaller.

The paper investigates feedback between social information use and production in fruit flies, finding bidirectional behavioral changes in males but not females during aggressive contests.

This study investigates how microbial environments influence oviposition decisions in Drosophila melanogaster, finding that microbial cues affect fecundity and egg placement but not antimicrobial activity.

This study examines temporal copulatory patterns in female rats, finding that receptivity influences sexual bout frequency and time-outs, while mating conditions affect less-receptive females.

This study shows that maternal and larval clocks independently control the timing of larval emergence in shell-dwelling cichlids, with each clock able to override the other under experimental conditions.

The paper develops statistical methods to detect social buffering effects using mixed-effects models and demonstrates their power and accuracy in empirical studies.

This study investigates whether predation risk experienced during the larval stage of Aedes aegypti influences antipredator behavior in the subsequent pupal stage.

The paper investigates aggression differences among throat color morphs in Aegean wall lizards in their natural habitat and finds that the white morph exhibits more aggression than orange and yellow morphs.

The paper tests neophobia in Eisenia fetida worms, identifying bold and shy behavioral profiles that may explain their invasive success.

The paper investigates whether habitat type-specific chemical fingerprints in fire salamander larvae predict adult mate preference by comparing chemical compositions in different aquatic habitats.

The paper identifies genomic regions and genes associated with Reed Warbler responses to Cuckoo brood parasitism across Europe using landscape genomics methods.

The paper examines how increased yolk testosterone affects DNA methylation and phenotypes in wild great tit nestlings, finding sex-specific methylation changes at 763 CpG sites linked to growth, oxidative stress, and reproduction.

This study shows that turquoise killifish males experience reproductive aging despite being short-lived, with declining sperm quality and reduced embryo survival as they age.

This study shows that in male mice, competition amplifies the impact of early life contingency, leading to divergent life trajectories, while this effect is absent in females.

This study develops an agent-based model to explore how costs of acquiring private and social information influence dispersal strategies in butterflies across stable and variable environments.

This study examines how socio-ecological factors influence sexual selection and mating strategies in Drosophila prolongata, showing context-dependent shifts in competition modes and trait significance.

This study shows that genetic rescue effectiveness depends on rescuer sexual selection background, but its benefits decline over generations in Red Flour Beetle populations.
