Color under pressure: how multiple factors shape defensive coloration
Behavioral ecologists have long studied the role of coloration as a defense against natural
enemies. Recent reviews of defensive coloration have emphasized that these visual signals …

Toward testing for multimodal perception of mating signals
Many mating signals consist of multimodal components that need decoding by several
sensory modalities on the receiver's side. For methodological and conceptual reasons, the …

Predator selection on phenotypic variability of cryptic and aposematic moths
Natural selection generally favours phenotypic variability in camouflaged organisms,
whereas aposematic organisms are expected to evolve a more uniform warning coloration …

How life became colourful: colour vision, aposematism, sexual selection, flowers, and fruits
Plants and animals are often adorned with potentially conspicuous colours (eg red, yellow,
orange, blue, purple). These include the dazzling colours of fruits and flowers, the brilliant …

First characterization of toxic alkaloids and volatile organic compounds (VOCs) in the cryptic dendrobatid Silverstoneia punctiventris
Background Poison frogs are known for the outstanding diversity of alkaloid-based chemical
defences with promising therapeutic applications. However, current knowledge about …

Model systems in ecology, evolution, and behavior: A call for diversity in our model systems and discipline
Ecologists and evolutionary biologists are fascinated by life's variation but also seek to
understand phenomena and mechanisms that apply broadly across taxa. Model systems …

Detectability of a poison frog and its Batesian mimic depends on body posture and viewing angle
Aposematic signals warn predators that prey should be avoided due to dangerous
secondary defences. However, as warning signals do not always produce avoidance …

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 …

Species specificity and intraspecific variation in the chemical profiles of Heliconius butterflies across a large geographic range
In many animals, mate choice is important for the maintenance of reproductive isolation
between species. Traits important for mate choice and behavioral isolation are predicted to …

Evolutionary potential and constraints in an aposematic species: Genetic correlations between warning coloration and fitness components in wood tiger moths
Variability in warning signals is common but remains puzzling since deviations from the
most common form should result in a higher number of predator attacks. One explanation …
