Animal Behavior and Reproduction

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.

The paper reanalyzes sperm length data from multiple Drosophila species using statistical clustering to determine the number of sperm morphs, finding that some species have two parasperm morphs while others have one.

The paper tests the status signaling hypothesis by measuring aggression toward painted plumage models in American Herring Gulls, finding that first-cycle and control plumages elicit less aggression than definitive plumage.

The paper examines a hybrid zone between two manakin species, finding reduced offspring viability in hybrids, which may explain the zone's long-term stability.

The paper tests for sexually antagonistic coevolution in Drosophila by analyzing female post-mating transcriptomes and finds no evidence of coevolution, instead supporting environmental and female-expressed genetic factors.

This study investigates whether cancer in zebrafish affects offspring sex ratio and survival, finding no effect on sex ratio but higher offspring survival from cancerous females.

The paper investigates genetically based sperm discrimination in primates by examining vaginal immune responses and pH changes after mating with genetically similar males.

This study examines social behavior consistency in cockroaches under varying humidity, finding that groups show higher plasticity variance than individuals.

The paper quantifies subcellular organelle allocation in nematode sperm using electron microscopy to determine if organelle investment correlates with sperm size evolution.

This study investigates clownfish color patterns and finds that specialists and generalists have distinct ecological and adaptive functions linked to their anemone hosts.

The paper uses long-term tracking of male mice to show that social rank is stable and influenced by individual behaviors, with chasing linked to rank negotiation.
