Animal Behavior and Reproduction

This study tests whether post-ejaculatory sperm environment affects offspring performance beyond paternity in capelin fish, finding no such effect.

The paper examines neuroanatomical changes in Heliconius butterflies during ecological speciation, finding heritable reductions in visual brain investment at high altitudes.

The paper introduces the risk-MVT (rMVT), a generalization of the Marginal Value Theorem that incorporates predation risk, showing how different risks affect optimal foraging strategies.

This study finds bold zebrafish learn faster in associative tasks than shy zebrafish, but final performance is similar, suggesting initial interactions, not learning capacity, drive differences.

This study shows that divergent selection increases reproductive isolation early in speciation, but not with more generations, and suggests phenotypic plasticity contributes to this pattern.

The paper identifies a novel male accessory gland peptide in the brown planthopper that reduces female post-mating receptivity without affecting oviposition.

This study investigates the effects of paternal age and sperm storage duration on offspring survival and reproduction in Drosophila, finding no age effect but a significant impact of sperm storage duration.

This study examines opsin gene expression and spectral sensitivity in male damselflies, finding plasticity in opsin expression that may influence their ability to detect female colour morphs.

This study examines how a transmissible cancer in Tasmanian devils affected breeding strategies and survival, finding no continued increase in precocial breeding or inbreeding depression.

The paper maps fitness landscapes to analyze sex allocation in hermaphrodites, finding that reproductive success peaks result from interactions between male and female allocations and inbreeding depression.

This study shows that early-life environmental conditions in hatcheries affect individual plasticity in juvenile lobsters' behavior and life-history traits, impacting conservation effectiveness.

This study investigates facultative sex in Lysiphlebus fabarum, finding that facultative sex does not confer fitness advantages and obligate sex provides fecundity benefits.

The paper examines how personal fitness incentives in wild banded mongooses affect intergroup conflict outcomes, finding that winning fights does not always translate to higher paternity success.

The paper investigates convergent evolution in cavity-nesting birds, finding behavioral similarities but limited gene expression convergence across species.

The paper assesses sexual selection on Drosophila wing color and morphology, finding that wing size and shape explain part of wing color variation and that sexual selection acts on a combination of color and morphology.

This study shows that positive evolutionary feedbacks increase aggression in Drosophila melanogaster, while negative feedbacks reduce it, demonstrating the impact of social dynamics on behavioral evolution.

This study demonstrates chemical mate choice copying in Drosophila melanogaster, showing females preferentially select male genotypes previously chosen by mated females.

The paper shows microbes can manipulate host reproduction in marine invertebrates by creating sperm-limited environments, driving transitions in developmental life-history strategies.

This study tests the hypothesis that resource defensibility facilitates weapon evolution by conducting experimental evolution in Drosophila melanogaster and observing changes in morphology and aggression.

The study examines how different types of social bonds in wild great tits affect reproductive success, finding varying impacts on clutch size, fledgling numbers, and laying dates.

Daphnia shows significant phenotypic plasticity in response to Microcystis exposure, but microbiome shifts are not correlated with the extent of this plasticity.

The paper investigates the relationship between female aggression and reproductive traits across eight Drosophila species, finding a correlation between aggression and ovariole number.

The paper investigates sex-biased dispersal in two polyandrous Jacana species, finding male-biased dispersal in Northern Jacanas and no bias in Wattled Jacanas, with sexually selected traits linked to philopatry in females.

This study investigates whether Drosophila melanogaster uses kin-based social information to guide oviposition decisions, finding that females prefer substrates associated with kin over those with unrelated conspecifics.

This study investigates how diet and the vgll3 gene affect maturation in female Atlantic salmon, finding genetic and environmental interactions influence age at maturity.

This study examines whether reduced nuptial gifts in nonsacculate Opiliones species are compensated by increased behavioural sexual conflict through comparative mating behaviour analysis.

The paper examines mate choice and male strategies in wood tiger moths, finding WW males have higher mating success but Wy females have higher reproductive success.

This study compares aquatic and terrestrial vertebrates to identify shifts in demographic and evolutionary constraints affecting life-history evolution, finding reduced diversification potential on land and differences in viviparity transitions.

The study shows transgenerational epigenetic inheritance in Daphnia exposed to Microcystis leads to reduced survival and growth rates, contradicting the idea that it is generally adaptive.

This paper revisits Rensch's Rule, expanding its application beyond sexual size dimorphism to other traits to better understand sexual dimorphism and phenotypic diversity.
