Multimodal aposematic signals and their emerging role in mate attraction
Chemically defended animals often display conspicuous color patterns that predators learn
to associate with their unprofitability and subsequently avoid. Such animals (ie, aposematic) …

3‐Alkyl‐2‐Methoxypyrazines: Overview of Their Occurrence, Biosynthesis and Distribution in Edible Plants
F Zamolo, M Wüst - ChemBioChem, 2023 - Wiley Online Library
Pyrazines are ubiquitous in nature–biosynthesized by microorganisms, insects, and plants.
Due to their great structural diversity, they own manifold biological functions. Alkyl‐and …

Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth
Warning signals are predicted to develop signal monomorphism via positive frequency‐
dependent selection (+ FDS) albeit many aposematic systems exhibit signal polymorphism …

Colour alone matters: no predator generalization among morphs of an aposematic moth
Local warning colour polymorphism, frequently observed in aposematic organisms, is
evolutionarily puzzling. This is because variation in aposematic signals is expected to be …

Multiple modalities in insect warning displays have additive effects against wild avian predators
Allocation to different components of defence has been suggested as an explanation for the
existence of multiple aposematic morphs in a single population. We tested whether there are …

Not just the sum of its parts: Geographic variation and nonadditive effects of pyrazines in the chemical defence of an aposematic moth
Chemical defences often vary within and between populations both in quantity and quality,
which is puzzling if prey survival is dependent on the strength of the defence. We …

Diet influences resource allocation in chemical defence but not melanin synthesis in an aposematic moth
For animals that synthesise their chemical compounds de novo, resources, particularly
proteins, can influence investment in chemical defences and nitrogen-based wing …
