Strength of developmental carry-over varies continuously with environmental conditions in a wild bird population

The paper shows that the strength of developmental carry-over from natal to adult body mass in great tits varies with environmental conditions, driven by non-genetic factors rather than gene-by-environment interactions.

Developmental stage-specific responses to extreme climatic events and environmental variability in great tit nestlings

This study shows that great tit nestlings experience different impacts from extreme climate events depending on their developmental stage, with cold events early on and rain events later having the strongest effects.

Chilling out or heating up? Thermal plasticity of seminal fluid proteins in Drosophila melanogaster

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

The developmental environment mediates adult seminal proteome allocation in male Drosophila melanogaster

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.

Mechanisms of phenotypic trade-offs in the resource acquisition-allocation Y-model

The paper simulates the Y-model to quantify phenotypic trade-offs, finding that mean allocation strategy, not mean resource acquisition, influences trade-offs, and that within-individual allocation dependence amplifies these effects.

Simulations provide a mechanistic interpretation of Bateman gradients

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

No evidence for paternal age effects on sons or daughters, when accounting for paternal sperm storage

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.

Sperm storage reduces sperm and embryo quality in animals

This study investigates how in-vivo sperm storage affects sperm quality, fertilization success, and offspring quality across humans and non-human animals, finding that storage duration and other factors influence these outcomes.

Does female post-copulatory preference depend on pre-copulatory choice and post-mating environment?

This study investigates whether female post-copulatory preference in Drosophila depends on pre-copulatory choice and post-mating environment, finding no effect of male presence but a link between mating latency and sperm ejection.

Genetic, natal, and spatial drivers of social phenotypes in wild great tits

This study identifies genetic, natal, and spatial factors influencing social behaviors in wild great tits, finding small genetic effects and significant non-genetic influences.

Reproductive output of old polygynous males is limited by seminal fluid, not sperm number

This study shows that reproductive decline in old polygynous males is due to seminal fluid limitations, not sperm number, using Drosophila melanogaster.

Quantitative proteomics identification of seminal fluid proteins in male Drosophila melanogaster

The paper identifies seminal fluid proteins in Drosophila melanogaster using label-free quantitative proteomics, finding novel candidates and re-evaluating previously reported proteins.
