Animal Behavior and Reproduction

The study finds that kin-sharing foraging grounds in solitary bush Karoo rats indicates mutual cooperation through kin selection and mutualism.

The paper examines the link between epigenetic potential and natal dispersal in Pied flycatchers, finding a positive association in certain comparisons but not others.

This study identifies discrete genetic modules underlying divergent reproductive strategies in three-spined stickleback, showing traits are genetically uncorrelated and map to different genomic regions.

The paper tests if weapon size in beetles is energetically costly by examining associations with metabolic rate, finding no significant link but identifying genetic and developmental influences on weapon size.

The paper tests whether male social dominance influences female mate choice and access to mates in pygmy halfbeaks, finding dominance affects access but not female preference.

This study shows that older mothers produce offspring with better development and growth efficiency, challenging the Lansing effect by demonstrating improved offspring performance with maternal age.

The paper shows that humidity, not temperature, regulates eyespot size in butterflies from populations where temperature is unreliable, and finds local adaptation in cue use and life history traits.

This study examines shoaling behavior in green chromides under various environmental manipulations, finding increased shoal fusion under stress and mixed-species shoaling with tilapia.

This study shows female fruit flies adjust egg clustering based on social cues, increasing clustering with group size and preferring mixed maternity clusters.

The paper examines age at first reproduction in three human populations under directional selection, finding low heritability and evolutionary stasis despite selection pressure.

The paper shows that strain-specific individual behaviours in C. elegans predict collective aggregation in mixed groups without altering individual movement patterns.

The paper reports the first observations of two fairy-wren species using anthropogenic materials in sexual displays to enhance reproductive fitness.

This study meta-analyzes the impact of transgenerational and developmental plasticity on stress responses, finding that experimental and biological context, rather than plasticity type alone, predicts stress tolerance outcomes.

The paper shows that environmental cues reduce selection against harmful alleles in seed beetles by enabling adaptive maternal care through learning.

This study identifies a multitiered social network structure in zebra finches, with distinct tiers of social contacts maintained by different mechanisms.

This study examines the effects of artificial selection for early dispersal on ambrosia beetles and their fungal symbionts, finding limited genetic response and changes in fungal communities.

This study uses artificial selection to show that clonal reproduction in Mimulus guttatus can evolve rapidly, with genetic correlations shaping the response to selection.

The paper investigates how habitat complexity affects sexual selection on brain size and ornamentation in pygmy halfbeaks, finding stronger selection for brain size in open environments.

The paper finds that male chickadees with better spatial cognition sire more extra-pair young and produce heavier offspring, supporting the good genes hypothesis.

This study examines how relaxing intralocus sexual conflict affects mate harm evolution in Drosophila melanogaster using experimental evolution.

The paper shows that lifespan variation in turquoise killifish is due to intrinsic quality rather than reproductive trade-offs.

This study investigates how temperature exposure affects seminal fluid protein production and transfer in Drosophila melanogaster under different sperm competition conditions.

This study tests intralocus sexual conflict in Drosophila melanogaster using male-limited selection, finding mixed evidence with reduced male fitness variation and female fitness costs.

This study shows that post-hatching acoustic communication in burying beetles compensates for prenatal disadvantages in larvae, highlighting its importance for growth.

This study investigates whether Common cuckoo females select high-quality hosts for egg-laying and finds that host selection does not target host quality but may influence cuckoo nestling growth.

This study investigates how wing development in grasshoppers is influenced by genetics, environment, and their interaction, showing heritable variation and density-dependent plasticity in dispersal dimorphism.

This study investigates how larval crowding affects seminal proteome allocation in Drosophila melanogaster males and females, finding that small males transfer more seminal proteins despite producing less overall.

This paper shows that the evolution of dominance in a Mendelian trait is linked to changes in phenotypic plasticity, specifically in the pdm3 gene across Drosophila species.

This study shows that early life adversity in rhesus macaques affects growth, reproductive timing, and lifetime reproductive success, with adversity intensifying trade-offs between growth and reproduction.

The paper identifies genetic trade-offs and antagonistic pleiotropy in Florida Scrub-Jays by analyzing fitness components and their genomic associations.
