Animal Behavior and Reproduction

The paper shows that groups of animals can detect threats more accurately than individuals by using social discounting, where stillness of neighbors signals safety and flight signals danger.

This paper tests whether Caenorhabditis elegans follows the Marginal Value Theorem in patchy environments, finding that it matches predictions through both behavioral adaptation and passive environmental interactions.

This study investigates how maternal effects and genetic variation jointly shape body size divergence in house mice, finding that maternal environment significantly influences early-life weight and is linked to nutrient signaling pathways.

This study shows that female Drosophila melanogaster adjust their reproductive output based on same-sex density, revealing density-dependent plasticity that mediates Allee effects.

This study models incubation schedules in Leachs Storm-Petrels to show how energetic tradeoffs and schedule breakdown lead to reproductive failure in harsh environments.

The study shows that social competence in cichlids is role-specific, with individuals excelling in one social role but not the other, suggesting stable behavioural tendencies.

The paper examines how boldness and sociability affect resource exploitation in California ground squirrels using automated foraging puzzles, finding boldness improves discovery and performance while sociability aids problem-solving.

This study investigates how Daphnia lumholtzi develops head and tailspines in response to predator cues, revealing a sustained hyperplasia mechanism distinct from other species.

The study uses capture-mark-recapture data to show female-biased dispersal in Ellobius talpinus, a subterranean rodent, with females having lower apparent survival than males across age classes.

This study examines how diet affects antipredator behavior and physiology in lizards, finding that high NPE diets lead to riskier perch choices during safe periods and higher corticosterone levels in low NPE diets.

The paper shows that maternal age at reproduction affects offspring life-history traits across two generations in predatory mites, with grandmaternal age mediating these effects.

The paper investigates how male mate preference learning in butterflies affects spermatophore protein composition and female reproductive outcomes.

The paper shows that environmental changes influence the complexity of mating displays and their persistence in changing climates.

The paper simulates secondary contact between populations to show how search costs and pleiotropy affect mating trait differentiation and species persistence.

The paper assesses the Z:A ratio as a genomic indicator of sexual selection in lekking birds, finding it influenced by demographic history and hybridization rather than solely sexual selection.

The paper compares human developmental timing with 462 mammalian species to show that human development follows general mammalian scaling patterns rather than being an outlier.

Heritable variation is maintained due to resource competition being more intense among kin.

The paper compares reproductive strategies in stickleback ecotypes, showing how hormonal tradeoffs shape life history divergence through gene expression and androgen production differences.

The paper applies the Bradley-Terry model to quantify sperm competition outcomes in Drosophila melanogaster by analyzing pairwise mating trials and estimating genotype-specific competitive success.

The paper measures aggression in Drosophila melanogaster inbred lines, finding sex differences and that male genotype does not affect post-mating female aggression changes.

This study tests if parental provisioning influences prey preferences in great tits, finding that innate biases against warning colors persist despite social learning.

This study investigates the role of stridulations in the mating of Nicrophorus vespilloides, finding that while not essential for courtship initiation, female stridulations may enhance copulation success.

This study shows that a male-expressed mating plug in nematodes increases female fertility by extending reproductive windows and reducing sperm loss, indicating reproductive cooperation rather than male competition.

The paper identifies genetic variation in Drosophila melanogaster that influences mating plug ejection timing, linking it to reproductive physiology and paternity outcomes.

This study examines how personality, sex, and learning influence the recombination of innovative behaviours in lovebirds during problem-solving tasks.

This study examines how female age affects receptivity and mating success in jumping spiders, finding age-dependent changes in courtship response patterns.

The paper examines how predation risk and nesting resources influence social complexity in cichlids, finding that predation risk promotes group living while resource availability limits its extent.

The paper tests if female reproductive fluid (FRF) in bitterling fish retains sperm-attracting properties despite their unique fertilization strategy involving water currents.

The study examines how food restriction affects genetic correlations between sexes in Drosophila prolongata, finding reduced intersex genetic covariances and increased sex-specific additive genetic variance.

The paper develops a kin-selection model to test whether menopause evolves through its effects on survival, fecundity, and indirect fitness benefits, supporting the 'mamas boy hypothesis'.
