Genetic architecture of cichlid brain morphology

The paper investigates the genetic architecture of brain morphology in cichlid fish, showing modular genetic control of brain components and weaker genetic correlations in hybrids.

Sexual dimorphism in pollen foraging and sensory traits in Heliconius butterflies

The paper examines sex-specific foraging strategies and sensory traits in Heliconius himera butterflies, finding females carry more pollen but both sexes forage on similar plants, with males having larger eyes and females larger mushroom bodies.

Repeated evolution of reduced visual investment at the onset of ecological speciation in high-altitude Heliconius butterflies.

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