Animal Behavior and Reproduction

This study tests developmental constraints and adaptive response hypotheses for early life effects on fertility in wild baboons but finds no strong support for these explanations.

This study investigates how food quality during different life stages affects stress coping and personality development in wild house mice, finding that early nutrition influences long-term behavioral strategies.

The paper tests if phoretic mites influence mate choice in burying beetles, finding no effect on female preference or offspring fitness.

This study shows three-spined sticklebacks use facial recognition to identify familiar individuals, distinguishing them from strangers based on facial features alone.

This paper conducts a meta-analysis of 226 effect sizes from 80 studies to examine how host personality traits relate to parasitic infection, finding that experimental infections reduce activity and exploration, while observational studies show activity-exploration correlates with infection risk.

The paper uses path analysis on Seychelles warbler data to examine factors influencing delayed offspring dispersal, finding territory quality and helper presence significantly affect dispersal decisions.

The paper tests if multisensory male displays improve female memory in tungara frogs, finding that memory is enhanced after signal fluctuations.

This study investigates how ecological and social factors influence sex-specific parental care in burying beetles, finding that females increase care on small carcasses and both sexes adjust care in response to competition.

This study shows that artificial selection for adult predation in guppies leads to changes in life history and morphology but not all predation-related traits.

The paper examines whether body color polymorphism in birds correlates with ecological success, finding that polymorphic species have larger ranges, lower extinction risk, and more stable populations.

This study investigates within- and transgenerational plasticity in Physa acuta by analyzing gene expression changes in response to predator cues across two generations.

The paper examines reproductive behavior differences among populations of Lymnaea stagnalis, finding distinct behavioral traits and no phylogenetic signals, suggesting evolutionary processes like divergent selection drive variation.

The paper uses simulations to show that Bateman gradients are influenced by covariances between mating success and other factors, not just direct causation.

This study examines how meerkats' spatial positions during foraging affect weight gain, finding age-related differences and unexpected outcomes for dominant females.

The paper measures yolk steroid hormone concentrations in Japanese Quail eggs during incubation and finds they decline by Day 15, with temperature differences between incubators affecting hormone levels.

This study examines how selection for male aggression in Drosophila melanogaster affects reproductive traits, chemical signaling, and lifespan, revealing trade-offs between reproductive success and longevity.

The paper develops a behavioral assay and uses a Hidden Markov Model to analyze bold-shy behaviors in medaka fish, identifying direct and social genetic effects on behavior.

The paper examines how multiple signaling traits in lizards correlate with physiological factors and social behavior, finding both redundancy and distinct signaling roles.

This study finds that two matings in female Drosophila melanogaster cause more genital and abdominal wounds than a single mating.

This study shows genetic heterogeneity in Drosophila leads to nonadditive increases in spatial preference and stopping time in group foraging behavior.

The paper uses circadian activity data and machine learning to predict breeding phenology in Nicrophorus nepalensis across different elevations and photoperiods, achieving high accuracy.

This study investigates the mechanisms behind correlated trait divergence during speciation, finding that environmental factors, not genetics, primarily drive the divergence of color patterns and chemical traits in stick insects.

This study shows that reproductive experience in male California mice affects memory, anxiety, and reproductive physiology, with caregiving and siring contributing differently to these changes.

The study assesses the repeatability of nest defense in female northern house wrens across different predator types and threat levels, finding it repeatable for similar and unknown risks but not for high-risk predators.

This study shows that group personality, not acoustic noise, drives variation in decision-making and cohesion in guppy shoals.

This study evaluates behavioral consistency in Baltic salmon parr, finding that locomotory activity is more consistent over time than thigmotaxis and aggressive behavior.

The paper examines extra-pair paternity in blue and great tits in a primeval forest, finding high promiscuity rates that do not impact reproductive success.

The paper presents a chromosome-level genome assembly for Uta stansburiana and uses RNA-seq data to identify gene expression differences linked to pace-of-life syndromes across environments.

The paper investigates how gut microbiomes affect sperm competition in Drosophila by testing synthetic bacterial consortia and identifies microbial effects on sperm transfer and viability.

This study examines how temperature and turbidity affect prey detectability by predators, finding that warmer water increases prey conspicuousness, counteracting the negative effects of turbidity.
