Phenotypic plasticity, heritability, and genotype-by-environment interactions in an insect dispersal polymorphism

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.

Plant diversity promotes aboveground arthropods and associated functions despite arthropod loss over time

The paper tracks arthropod communities and their functions over 13 years in grasslands with varying plant richness, finding that plant diversity supports arthropods and their functions despite overall declines.

Three species, three labs, three experiments: testing the reproducibility of ecological studies on insect behaviour in a multi-laboratory setting

This study tests the reproducibility of insect behavior experiments across three labs and species, finding 83% successful replication of treatment effects but only 66% effect size replication.

Strength of purifying selection on the amino-acid sequence is associated with the amount of non-additive variance in gene expression.

The study finds that genes with higher non-additive variance in expression show stronger purifying selection and lower synonymous variation in Arabidopsis lyrata.

partR2: Partitioning R2 in generalized linear mixed models

partR2 quantifies part R2 and structure coefficients for fixed effects in generalized linear mixed models, providing variance decomposition and confidence intervals.

General methods for evolutionary quantitative genetic inference from generalised mixed models.

This paper provides methods to infer evolutionary quantitative genetic parameters from generalized linear mixed models, enabling prediction of response to selection for non-normal traits.
