Diet influences resource allocation in chemical defence but not melanin synthesis in an aposematic moth

The paper tests how larval diet affects chemical defence and melanin synthesis in moths, finding resource trade-offs in defences but not in melanin.

Not just the sum of its parts: geographic variation and non-additive effects of pyrazines in the chemical defence of an aposematic moth

The paper investigates geographic variation and non-additive effects of pyrazines in the chemical defence of the wood tiger moth, finding that SBMP and IBMP have complex interactions and efficacy depending on concentration and predator context.

Experimental evolution of a pheromone signal

This study shows that artificial selection on a multicomponent pheromone signal in moths leads to a genetic covariance shift, enabling a response to selection without constraints from other linked components.

Toward an understanding of the chemical ecology of alternative reproductive tactics in the bulb mite (Rhizoglyphus robini)

The paper investigates pheromone production differences between alternative reproductive tactics in bulb mites, finding that scramblers produce more pheromones and reach larger sizes than fighters.

Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth

The paper shows that avian predator selection on warning coloration in moths varies geographically, with stronger positive frequency-dependent selection in monomorphic populations and weaker selection in polymorphic ones.
